ServiceDiscovery **************** Client ====== class ServiceDiscovery.Client A low-level client representing AWS Cloud Map (ServiceDiscovery) With Cloud Map, you can configure public DNS, private DNS, or HTTP namespaces that your microservice applications run in. When an instance becomes available, you can call the Cloud Map API to register the instance with Cloud Map. For public or private DNS namespaces, Cloud Map automatically creates DNS records and an optional health check. Clients that submit public or private DNS queries, or HTTP requests, for the service receive an answer that contains up to eight healthy records. import boto3 client = boto3.client('servicediscovery') These are the available methods: * can_paginate * close * create_http_namespace * create_private_dns_namespace * create_public_dns_namespace * create_service * delete_namespace * delete_service * delete_service_attributes * deregister_instance * discover_instances * discover_instances_revision * get_instance * get_instances_health_status * get_namespace * get_operation * get_paginator * get_service * get_service_attributes * get_waiter * list_instances * list_namespaces * list_operations * list_services * list_tags_for_resource * register_instance * tag_resource * untag_resource * update_http_namespace * update_instance_custom_health_status * update_private_dns_namespace * update_public_dns_namespace * update_service * update_service_attributes Paginators ========== Paginators are available on a client instance via the "get_paginator" method.

DNS_HTTP The service instances can be discovered using either DNS queries or the "DiscoverInstances" API operation. HTTP The service instances can only be discovered using the "DiscoverInstances" API operation. DNS Reserved. * **Description** *(string) --* The description that you specify when you create the service. * **InstanceCount** *(integer) --* The number of instances that are currently associated with the service. Instances that were previously associated with the service but that are deleted aren't included in the count. The count might not reflect pending registrations and deregistrations. * **DnsConfig** *(dict) --* Information about the Route 53 DNS records that you want Cloud Map to create when you register an instance. * **NamespaceId** *(string) --* Use NamespaceId in Service instead. The ID of the namespace to use for DNS configuration. * **RoutingPolicy** *(string) --* The routing policy that you want to apply to all Route 53 DNS records that Cloud Map creates when you register an instance and specify this service. Note: If you want to use this service to register instances that create alias records, specify "WEIGHTED" for the routing policy. You can specify the following values: MULTIVALUE If you define a health check for the service and the health check is healthy, Route 53 returns the applicable value for up to eight instances. For example, suppose that the service includes configurations for one "A" record and a health check. You use the service to register 10 instances. Route 53 responds to DNS queries with IP addresses for up to eight healthy instances. If fewer than eight instances are healthy, Route 53 responds to every DNS query with the IP addresses for all of the healthy instances. If you don't define a health check for the service, Route 53 assumes that all instances are healthy and returns the values for up to eight instances. For more information about the multivalue routing policy, see Multivalue Answer Routing in the *Route 53 Developer Guide*. WEIGHTED Route 53 returns the applicable value from one randomly selected instance from among the instances that you registered using the same service. Currently, all records have the same weight, so you can't route more or less traffic to any instances. For example, suppose that the service includes configurations for one "A" record and a health check. You use the service to register 10 instances. Route 53 responds to DNS queries with the IP address for one randomly selected instance from among the healthy instances. If no instances are healthy, Route 53 responds to DNS queries as if all of the instances were healthy. If you don't define a health check for the service, Route 53 assumes that all instances are healthy and returns the applicable value for one randomly selected instance. For more information about the weighted routing policy, see Weighted Routing in the *Route 53 Developer Guide*. * **DnsRecords** *(list) --* An array that contains one "DnsRecord" object for each Route 53 DNS record that you want Cloud Map to create when you register an instance. Warning: The record type of a service specified in a "DnsRecord" object can't be updated. To change a record type, you need to delete the service and recreate it with a new "DnsConfig". * *(dict) --* A complex type that contains information about the Route 53 DNS records that you want Cloud Map to create when you register an instance. * **Type** *(string) --* The type of the resource, which indicates the type of value that Route 53 returns in response to DNS queries. You can specify values for "Type" in the following combinations: * "A" * "AAAA" * "A" and "AAAA" * "SRV" * "CNAME" If you want Cloud Map to create a Route 53 alias record when you register an instance, specify "A" or "AAAA" for "Type". You specify other settings, such as the IP address for "A" and "AAAA" records, when you register an instance. For more information, see RegisterInstance. The following values are supported: A Route 53 returns the IP address of the resource in IPv4 format, such as 192.0.2.44. AAAA Route 53 returns the IP address of the resource in IPv6 format, such as 2001:0db8:85a3:0000:0000:abcd:0001:2345. CNAME Route 53 returns the domain name of the resource, such as www.example.com. Note the following: * You specify the domain name that you want to route traffic to when you register an instance. For more information, see Attributes in the topic RegisterInstance. * You must specify "WEIGHTED" for the value of "RoutingPolicy". * You can't specify both "CNAME" for "Type" and settings for "HealthCheckConfig". If you do, the request will fail with an "InvalidInput" error. SRV Route 53 returns the value for an "SRV" record. The value for an "SRV" record uses the following values: "priority weight port service-hostname" Note the following about the values: * The values of "priority" and "weight" are both set to "1" and can't be changed. * The value of "port" comes from the value that you specify for the "AWS_INSTANCE_PORT" attribute when you submit a RegisterInstance request. * The value of "service-hostname" is a concatenation of the following values: * The value that you specify for "InstanceId" when you register an instance. * The name of the service. * The name of the namespace. For example, if the value of "InstanceId" is "test", the name of the service is "backend", and the name of the namespace is "example.com", the value of "service-hostname" is the following: "test.backend.example.com" If you specify settings for an "SRV" record, note the following: * If you specify values for "AWS_INSTANCE_IPV4", "AWS_INSTANCE_IPV6", or both in the "RegisterInstance" request, Cloud Map automatically creates "A" and/or "AAAA" records that have the same name as the value of "service-hostname" in the "SRV" record. You can ignore these records. * If you're using a system that requires a specific "SRV" format, such as HAProxy, see the Name element in the documentation about "CreateService" for information about how to specify the correct name format. * **TTL** *(integer) --* The amount of time, in seconds, that you want DNS resolvers to cache the settings for this record. Note: Alias records don't include a TTL because Route 53 uses the TTL for the Amazon Web Services resource that an alias record routes traffic to. If you include the "AWS_ALIAS_DNS_NAME" attribute when you submit a RegisterInstance request, the "TTL" value is ignored. Always specify a TTL for the service; you can use a service to register instances that create either alias or non-alias records. * **HealthCheckConfig** *(dict) --* *Public DNS and HTTP namespaces only.* Settings for an optional health check. If you specify settings for a health check, Cloud Map associates the health check with the records that you specify in "DnsConfig". * **Type** *(string) --* The type of health check that you want to create, which indicates how Route 53 determines whether an endpoint is healthy. Warning: You can't change the value of "Type" after you create a health check. You can create the following types of health checks: * **HTTP**: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTP request and waits for an HTTP status code of 200 or greater and less than 400. * **HTTPS**: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTPS request and waits for an HTTP status code of 200 or greater and less than 400. Warning: If you specify HTTPS for the value of "Type", the endpoint must support TLS v1.0 or later. * **TCP**: Route 53 tries to establish a TCP connection. If you specify "TCP" for "Type", don't specify a value for "ResourcePath". For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the *Route 53 Developer Guide*. * **ResourcePath** *(string) --* The path that you want Route 53 to request when performing health checks. The path can be any value that your endpoint returns an HTTP status code of a 2xx or 3xx format for when the endpoint is healthy. An example file is "/docs/route53-health- check.html". Route 53 automatically adds the DNS name for the service. If you don't specify a value for "ResourcePath", the default value is "/". If you specify "TCP" for "Type", you must *not* specify a value for "ResourcePath". * **FailureThreshold** *(integer) --* The number of consecutive health checks that an endpoint must pass or fail for Route 53 to change the current status of the endpoint from unhealthy to healthy or the other way around. For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the *Route 53 Developer Guide*. * **HealthCheckCustomConfig** *(dict) --* Information about an optional custom health check. A custom health check, which requires that you use a third-party health checker to evaluate the health of your resources, is useful in the following circumstances: * You can't use a health check that's defined by "HealthCheckConfig" because the resource isn't available over the internet. For example, you can use a custom health check when the instance is in an Amazon VPC. (To check the health of resources in a VPC, the health checker must also be in the VPC.) * You want to use a third-party health checker regardless of where your resources are located. Warning: If you specify a health check configuration, you can specify either "HealthCheckCustomConfig" or "HealthCheckConfig" but not both. * **FailureThreshold** *(integer) --* Warning: This parameter is no longer supported and is always set to 1. Cloud Map waits for approximately 30 seconds after receiving an "UpdateInstanceCustomHealthStatus" request before changing the status of the service instance. The number of 30-second intervals that you want Cloud Map to wait after receiving an "UpdateInstanceCustomHealthStatus" request before it changes the health status of a service instance. Sending a second or subsequent "UpdateInstanceCustomHealthStatus" request with the same value before 30 seconds has passed doesn't accelerate the change. Cloud Map still waits "30" seconds after the first request to make the change. * **CreateDate** *(datetime) --* The date and time that the service was created. ServiceDiscovery / Client / create_public_dns_namespace create_public_dns_namespace *************************** ServiceDiscovery.Client.create_public_dns_namespace(**kwargs) Creates a public namespace based on DNS, which is visible on the internet. The namespace defines your service naming scheme. For example, if you name your namespace "example.com" and name your service "backend", the resulting DNS name for the service is "backend.example.com". You can discover instances that were registered with a public DNS namespace by using either a "DiscoverInstances" request or using DNS. For the current quota on the number of namespaces that you can create using the same Amazon Web Services account, see Cloud Map quotas in the *Cloud Map Developer Guide*. Warning: The "CreatePublicDnsNamespace" API operation is not supported in the Amazon Web Services GovCloud (US) Regions.

You can specify values for "Type" in the following combinations: * "A" * "AAAA" * "A" and "AAAA" * "SRV" * "CNAME" If you want Cloud Map to create a Route 53 alias record when you register an instance, specify "A" or "AAAA" for "Type". You specify other settings, such as the IP address for "A" and "AAAA" records, when you register an instance. For more information, see RegisterInstance. The following values are supported: A Route 53 returns the IP address of the resource in IPv4 format, such as 192.0.2.44. AAAA Route 53 returns the IP address of the resource in IPv6 format, such as 2001:0db8:85a3:0000:0000:abcd:0001:2345. CNAME Route 53 returns the domain name of the resource, such as www.example.com. Note the following: * You specify the domain name that you want to route traffic to when you register an instance. For more information, see Attributes in the topic RegisterInstance. * You must specify "WEIGHTED" for the value of "RoutingPolicy". * You can't specify both "CNAME" for "Type" and settings for "HealthCheckConfig". If you do, the request will fail with an "InvalidInput" error. SRV Route 53 returns the value for an "SRV" record. The value for an "SRV" record uses the following values: "priority weight port service-hostname" Note the following about the values: * The values of "priority" and "weight" are both set to "1" and can't be changed. * The value of "port" comes from the value that you specify for the "AWS_INSTANCE_PORT" attribute when you submit a RegisterInstance request. * The value of "service-hostname" is a concatenation of the following values: * The value that you specify for "InstanceId" when you register an instance. * The name of the service. * The name of the namespace. For example, if the value of "InstanceId" is "test", the name of the service is "backend", and the name of the namespace is "example.com", the value of "service- hostname" is the following: "test.backend.example.com" If you specify settings for an "SRV" record, note the following: * If you specify values for "AWS_INSTANCE_IPV4", "AWS_INSTANCE_IPV6", or both in the "RegisterInstance" request, Cloud Map automatically creates "A" and/or "AAAA" records that have the same name as the value of "service-hostname" in the "SRV" record. You can ignore these records. * If you're using a system that requires a specific "SRV" format, such as HAProxy, see the Name element in the documentation about "CreateService" for information about how to specify the correct name format. * **TTL** *(integer) --* **[REQUIRED]** The amount of time, in seconds, that you want DNS resolvers to cache the settings for this record. Note: Alias records don't include a TTL because Route 53 uses the TTL for the Amazon Web Services resource that an alias record routes traffic to. If you include the "AWS_ALIAS_DNS_NAME" attribute when you submit a RegisterInstance request, the "TTL" value is ignored. Always specify a TTL for the service; you can use a service to register instances that create either alias or non-alias records. * **HealthCheckConfig** *(dict) --* *Public DNS and HTTP namespaces only.* Settings for an optional health check. If you specify settings for a health check, Cloud Map associates the health check with the records that you specify in "DnsConfig". * **Type** *(string) --* **[REQUIRED]** The type of health check that you want to create, which indicates how Route 53 determines whether an endpoint is healthy. Warning: You can't change the value of "Type" after you create a health check. You can create the following types of health checks: * **HTTP**: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTP request and waits for an HTTP status code of 200 or greater and less than 400. * **HTTPS**: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTPS request and waits for an HTTP status code of 200 or greater and less than 400. Warning: If you specify HTTPS for the value of "Type", the endpoint must support TLS v1.0 or later. * **TCP**: Route 53 tries to establish a TCP connection. If you specify "TCP" for "Type", don't specify a value for "ResourcePath". For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the *Route 53 Developer Guide*. * **ResourcePath** *(string) --* The path that you want Route 53 to request when performing health checks. The path can be any value that your endpoint returns an HTTP status code of a 2xx or 3xx format for when the endpoint is healthy. An example file is "/docs/route53-health-check.html". Route 53 automatically adds the DNS name for the service. If you don't specify a value for "ResourcePath", the default value is "/". If you specify "TCP" for "Type", you must *not* specify a value for "ResourcePath". * **FailureThreshold** *(integer) --* The number of consecutive health checks that an endpoint must pass or fail for Route 53 to change the current status of the endpoint from unhealthy to healthy or the other way around.

You can specify the following values: MULTIVALUE If you define a health check for the service and the health check is healthy, Route 53 returns the applicable value for up to eight instances. For example, suppose that the service includes configurations for one "A" record and a health check. You use the service to register 10 instances. Route 53 responds to DNS queries with IP addresses for up to eight healthy instances. If fewer than eight instances are healthy, Route 53 responds to every DNS query with the IP addresses for all of the healthy instances. If you don't define a health check for the service, Route 53 assumes that all instances are healthy and returns the values for up to eight instances.

WEIGHTED Route 53 returns the applicable value from one randomly selected instance from among the instances that you registered using the same service. Currently, all records have the same weight, so you can't route more or less traffic to any instances. For example, suppose that the service includes configurations for one "A" record and a health check. You use the service to register 10 instances. Route 53 responds to DNS queries with the IP address for one randomly selected instance from among the healthy instances. If no instances are healthy, Route 53 responds to DNS queries as if all of the instances were healthy. If you don't define a health check for the service, Route 53 assumes that all instances are healthy and returns the applicable value for one randomly selected instance. For more information about the weighted routing policy, see Weighted Routing in the *Route 53 Developer Guide*. * **DnsRecords** *(list) --* An array that contains one "DnsRecord" object for each Route 53 DNS record that you want Cloud Map to create when you register an instance. Warning: The record type of a service specified in a "DnsRecord" object can't be updated. To change a record type, you need to delete the service and recreate it with a new "DnsConfig". * *(dict) --* A complex type that contains information about the Route 53 DNS records that you want Cloud Map to create when you register an instance. * **Type** *(string) --* The type of the resource, which indicates the type of value that Route 53 returns in response to DNS queries. You can specify values for "Type" in the following combinations: * "A" * "AAAA" * "A" and "AAAA" * "SRV" * "CNAME" If you want Cloud Map to create a Route 53 alias record when you register an instance, specify "A" or "AAAA" for "Type". You specify other settings, such as the IP address for "A" and "AAAA" records, when you register an instance. For more information, see RegisterInstance. The following values are supported: A Route 53 returns the IP address of the resource in IPv4 format, such as 192.0.2.44. AAAA Route 53 returns the IP address of the resource in IPv6 format, such as 2001:0db8:85a3:0000:0000:abcd:0001:2345. CNAME Route 53 returns the domain name of the resource, such as www.example.com. Note the following: * You specify the domain name that you want to route traffic to when you register an instance. For more information, see Attributes in the topic RegisterInstance. * You must specify "WEIGHTED" for the value of "RoutingPolicy". * You can't specify both "CNAME" for "Type" and settings for "HealthCheckConfig". If you do, the request will fail with an "InvalidInput" error. SRV Route 53 returns the value for an "SRV" record. The value for an "SRV" record uses the following values: "priority weight port service-hostname" Note the following about the values: * The values of "priority" and "weight" are both set to "1" and can't be changed. * The value of "port" comes from the value that you specify for the "AWS_INSTANCE_PORT" attribute when you submit a RegisterInstance request. * The value of "service-hostname" is a concatenation of the following values: * The value that you specify for "InstanceId" when you register an instance. * The name of the service. * The name of the namespace. For example, if the value of "InstanceId" is "test", the name of the service is "backend", and the name of the namespace is "example.com", the value of "service-hostname" is the following: "test.backend.example.com" If you specify settings for an "SRV" record, note the following: * If you specify values for "AWS_INSTANCE_IPV4", "AWS_INSTANCE_IPV6", or both in the "RegisterInstance" request, Cloud Map automatically creates "A" and/or "AAAA" records that have the same name as the value of "service-hostname" in the "SRV" record. You can ignore these records. * If you're using a system that requires a specific "SRV" format, such as HAProxy, see the Name element in the documentation about "CreateService" for information about how to specify the correct name format. * **TTL** *(integer) --* The amount of time, in seconds, that you want DNS resolvers to cache the settings for this record. Note: Alias records don't include a TTL because Route 53 uses the TTL for the Amazon Web Services resource that an alias record routes traffic to. If you include the "AWS_ALIAS_DNS_NAME" attribute when you submit a RegisterInstance request, the "TTL" value is ignored. Always specify a TTL for the service; you can use a service to register instances that create either alias or non-alias records. * **HealthCheckConfig** *(dict) --* *Public DNS and HTTP namespaces only.* Settings for an optional health check. If you specify settings for a health check, Cloud Map associates the health check with the records that you specify in "DnsConfig". * **Type** *(string) --* The type of health check that you want to create, which indicates how Route 53 determines whether an endpoint is healthy. Warning: You can't change the value of "Type" after you create a health check. You can create the following types of health checks: * **HTTP**: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTP request and waits for an HTTP status code of 200 or greater and less than 400. * **HTTPS**: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTPS request and waits for an HTTP status code of 200 or greater and less than 400. Warning: If you specify HTTPS for the value of "Type", the endpoint must support TLS v1.0 or later. * **TCP**: Route 53 tries to establish a TCP connection. If you specify "TCP" for "Type", don't specify a value for "ResourcePath". For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the *Route 53 Developer Guide*. * **ResourcePath** *(string) --* The path that you want Route 53 to request when performing health checks. The path can be any value that your endpoint returns an HTTP status code of a 2xx or 3xx format for when the endpoint is healthy. An example file is "/docs/route53-health-check.html". Route 53 automatically adds the DNS name for the service. If you don't specify a value for "ResourcePath", the default value is "/". If you specify "TCP" for "Type", you must *not* specify a value for "ResourcePath". * **FailureThreshold** *(integer) --* The number of consecutive health checks that an endpoint must pass or fail for Route 53 to change the current status of the endpoint from unhealthy to healthy or the other way around. For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the *Route 53 Developer Guide*. * **HealthCheckCustomConfig** *(dict) --* Information about an optional custom health check. A custom health check, which requires that you use a third-party health checker to evaluate the health of your resources, is useful in the following circumstances: * You can't use a health check that's defined by "HealthCheckConfig" because the resource isn't available over the internet. For example, you can use a custom health check when the instance is in an Amazon VPC. (To check the health of resources in a VPC, the health checker must also be in the VPC.) * You want to use a third-party health checker regardless of where your resources are located. Warning: If you specify a health check configuration, you can specify either "HealthCheckCustomConfig" or "HealthCheckConfig" but not both. * **FailureThreshold** *(integer) --* Warning: This parameter is no longer supported and is always set to 1. Cloud Map waits for approximately 30 seconds after receiving an "UpdateInstanceCustomHealthStatus" request before changing the status of the service instance. The number of 30-second intervals that you want Cloud Map to wait after receiving an "UpdateInstanceCustomHealthStatus" request before it changes the health status of a service instance. Sending a second or subsequent "UpdateInstanceCustomHealthStatus" request with the same value before 30 seconds has passed doesn't accelerate the change. Cloud Map still waits "30" seconds after the first request to make the change. * **CreateDate** *(datetime) --* The date and time that the service was created. * **NextToken** *(string) --* If the response contains "NextToken", submit another "ListServices" request to get the next group of results. Specify the value of "NextToken" from the previous response in the next request. Note: Cloud Map gets "MaxResults" services and then filters them based on the specified criteria. It's possible that no services in the first "MaxResults" services matched the specified criteria but that subsequent groups of "MaxResults" services do contain services that match the criteria. **Exceptions** * "ServiceDiscovery.Client.exceptions.InvalidInput" **Examples** Example: List services response = client.list_services( ) print(response) Expected Output: { 'Services': [ { 'Arn': 'arn:aws:servicediscovery:us-west-2:123456789012:service/srv-p5zdwlg5uvvzjita', 'CreateDate': 1587081768.334, 'DnsConfig': { 'DnsRecords': [ { 'TTL': 60, 'Type': 'A', }, ], 'RoutingPolicy': 'MULTIVALUE', }, 'Id': 'srv-p5zdwlg5uvvzjita', 'Name': 'myservice', }, ], 'ResponseMetadata': { '...': '...', }, } ServiceDiscovery / Client / delete_service delete_service ************** ServiceDiscovery.Client.delete_service(**kwargs) Deletes a specified service and all associated service attributes.

Note: Do not include sensitive information in the name if the namespace is discoverable by public DNS queries. If you want Cloud Map to create an "SRV" record when you register an instance and you're using a system that requires a specific "SRV" format, such as HAProxy, specify the following for "Name": * Start the name with an underscore (_), such as "_exampleservice". * End the name with *._protocol*, such as "._tcp". When you register an instance, Cloud Map creates an "SRV" record and assigns a name to the record by concatenating the service name and the namespace name (for example, "_exampleservice._tcp.example.com"). Note: For services that are accessible by DNS queries, you can't create multiple services with names that differ only by case (such as EXAMPLE and example). Otherwise, these services have the same DNS name and can't be distinguished. However, if you use a namespace that's only accessible by API calls, then you can create services that with names that differ only by case. * **NamespaceId** (*string*) -- The ID of the namespace that you want to use to create the service. The namespace ID must be specified, but it can be specified either here or in the "DnsConfig" object. * **CreatorRequestId** (*string*) -- A unique string that identifies the request and that allows failed "CreateService" requests to be retried without the risk of running the operation twice. "CreatorRequestId" can be any unique string (for example, a date/timestamp). This field is autopopulated if not provided. * **Description** (*string*) -- A description for the service. * **DnsConfig** (*dict*) -- A complex type that contains information about the Amazon Route 53 records that you want Cloud Map to create when you register an instance. * **NamespaceId** *(string) --* Use NamespaceId in Service instead. The ID of the namespace to use for DNS configuration. * **RoutingPolicy** *(string) --* The routing policy that you want to apply to all Route 53 DNS records that Cloud Map creates when you register an instance and specify this service. Note: If you want to use this service to register instances that create alias records, specify "WEIGHTED" for the routing policy. You can specify the following values: MULTIVALUE If you define a health check for the service and the health check is healthy, Route 53 returns the applicable value for up to eight instances. For example, suppose that the service includes configurations for one "A" record and a health check. You use the service to register 10 instances.

DNS Reserved. * **HealthCheckConfig** *(dict) --* *Public DNS and HTTP namespaces only.* A complex type that contains settings for an optional health check. If you specify settings for a health check, Cloud Map associates the health check with the records that you specify in "DnsConfig". For information about the charges for health checks, see Amazon Route 53 Pricing. * **Type** *(string) --* The type of health check that you want to create, which indicates how Route 53 determines whether an endpoint is healthy. Warning: You can't change the value of "Type" after you create a health check. You can create the following types of health checks: * **HTTP**: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTP request and waits for an HTTP status code of 200 or greater and less than 400. * **HTTPS**: Route 53 tries to establish a TCP connection. If successful, Route 53 submits an HTTPS request and waits for an HTTP status code of 200 or greater and less than 400. Warning: If you specify HTTPS for the value of "Type", the endpoint must support TLS v1.0 or later. * **TCP**: Route 53 tries to establish a TCP connection. If you specify "TCP" for "Type", don't specify a value for "ResourcePath". For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the *Route 53 Developer Guide*. * **ResourcePath** *(string) --* The path that you want Route 53 to request when performing health checks. The path can be any value that your endpoint returns an HTTP status code of a 2xx or 3xx format for when the endpoint is healthy. An example file is "/docs/route53-health-check.html". Route 53 automatically adds the DNS name for the service. If you don't specify a value for "ResourcePath", the default value is "/". If you specify "TCP" for "Type", you must *not* specify a value for "ResourcePath". * **FailureThreshold** *(integer) --* The number of consecutive health checks that an endpoint must pass or fail for Route 53 to change the current status of the endpoint from unhealthy to healthy or the other way around. For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the *Route 53 Developer Guide*. * **HealthCheckCustomConfig** *(dict) --* A complex type that contains information about an optional custom health check. Warning: If you specify a health check configuration, you can specify either "HealthCheckCustomConfig" or "HealthCheckConfig" but not both. * **FailureThreshold** *(integer) --* Warning: This parameter is no longer supported and is always set to 1. Cloud Map waits for approximately 30 seconds after receiving an "UpdateInstanceCustomHealthStatus" request before changing the status of the service instance. The number of 30-second intervals that you want Cloud Map to wait after receiving an "UpdateInstanceCustomHealthStatus" request before it changes the health status of a service instance. Sending a second or subsequent "UpdateInstanceCustomHealthStatus" request with the same value before 30 seconds has passed doesn't accelerate the change. Cloud Map still waits "30" seconds after the first request to make the change. * **CreateDate** *(datetime) --* The date and time that the service was created, in Unix format and Coordinated Universal Time (UTC). The value of "CreateDate" is accurate to milliseconds. For example, the value "1516925490.087" represents Friday, January 26, 2018 12:11:30.087 AM. * **CreatorRequestId** *(string) --* A unique string that identifies the request and that allows failed requests to be retried without the risk of running the operation twice.

The count might not reflect pending registrations and deregistrations. * **DnsConfig** *(dict) --* A complex type that contains information about the Route 53 DNS records that you want Cloud Map to create when you register an instance. Warning: The record types of a service can only be changed by deleting the service and recreating it with a new "Dnsconfig". * **NamespaceId** *(string) --* Use NamespaceId in Service instead. The ID of the namespace to use for DNS configuration. * **RoutingPolicy** *(string) --* The routing policy that you want to apply to all Route 53 DNS records that Cloud Map creates when you register an instance and specify this service. Note: If you want to use this service to register instances that create alias records, specify "WEIGHTED" for the routing policy. You can specify the following values: MULTIVALUE If you define a health check for the service and the health check is healthy, Route 53 returns the applicable value for up to eight instances. For example, suppose that the service includes configurations for one "A" record and a health check. You use the service to register 10 instances. Route 53 responds to DNS queries with IP addresses for up to eight healthy instances. If fewer than eight instances are healthy, Route 53 responds to every DNS query with the IP addresses for all of the healthy instances. If you don't define a health check for the service, Route 53 assumes that all instances are healthy and returns the values for up to eight instances. For more information about the multivalue routing policy, see Multivalue Answer Routing in the *Route 53 Developer Guide*. WEIGHTED Route 53 returns the applicable value from one randomly selected instance from among the instances that you registered using the same service. Currently, all records have the same weight, so you can't route more or less traffic to any instances. For example, suppose that the service includes configurations for one "A" record and a health check. You use the service to register 10 instances. Route 53 responds to DNS queries with the IP address for one randomly selected instance from among the healthy instances. If no instances are healthy, Route 53 responds to DNS queries as if all of the instances were healthy. If you don't define a health check for the service, Route 53 assumes that all instances are healthy and returns the applicable value for one randomly selected instance. For more information about the weighted routing policy, see Weighted Routing in the *Route 53 Developer Guide*. * **DnsRecords** *(list) --* An array that contains one "DnsRecord" object for each Route 53 DNS record that you want Cloud Map to create when you register an instance. Warning: The record type of a service specified in a "DnsRecord" object can't be updated. To change a record type, you need to delete the service and recreate it with a new "DnsConfig". * *(dict) --* A complex type that contains information about the Route 53 DNS records that you want Cloud Map to create when you register an instance. * **Type** *(string) --* The type of the resource, which indicates the type of value that Route 53 returns in response to DNS queries. You can specify values for "Type" in the following combinations: * "A" * "AAAA" * "A" and "AAAA" * "SRV" * "CNAME" If you want Cloud Map to create a Route 53 alias record when you register an instance, specify "A" or "AAAA" for "Type". You specify other settings, such as the IP address for "A" and "AAAA" records, when you register an instance. For more information, see RegisterInstance. The following values are supported: A Route 53 returns the IP address of the resource in IPv4 format, such as 192.0.2.44. AAAA Route 53 returns the IP address of the resource in IPv6 format, such as 2001:0db8:85a3:0000:0000:abcd:0001:2345. CNAME Route 53 returns the domain name of the resource, such as www.example.com. Note the following: * You specify the domain name that you want to route traffic to when you register an instance. For more information, see Attributes in the topic RegisterInstance. * You must specify "WEIGHTED" for the value of "RoutingPolicy". * You can't specify both "CNAME" for "Type" and settings for "HealthCheckConfig". If you do, the request will fail with an "InvalidInput" error. SRV Route 53 returns the value for an "SRV" record. The value for an "SRV" record uses the following values: "priority weight port service-hostname" Note the following about the values: * The values of "priority" and "weight" are both set to "1" and can't be changed. * The value of "port" comes from the value that you specify for the "AWS_INSTANCE_PORT" attribute when you submit a RegisterInstance request. * The value of "service-hostname" is a concatenation of the following values: * The value that you specify for "InstanceId" when you register an instance. * The name of the service. * The name of the namespace. For example, if the value of "InstanceId" is "test", the name of the service is "backend", and the name of the namespace is "example.com", the value of "service-hostname" is the following: "test.backend.example.com" If you specify settings for an "SRV" record, note the following: * If you specify values for "AWS_INSTANCE_IPV4", "AWS_INSTANCE_IPV6", or both in the "RegisterInstance" request, Cloud Map automatically creates "A" and/or "AAAA" records that have the same name as the value of "service- hostname" in the "SRV" record. You can ignore these records. * If you're using a system that requires a specific "SRV" format, such as HAProxy, see the Name element in the documentation about "CreateService" for information about how to specify the correct name format. * **TTL** *(integer) --* The amount of time, in seconds, that you want DNS resolvers to cache the settings for this record. Note: Alias records don't include a TTL because Route 53 uses the TTL for the Amazon Web Services resource that an alias record routes traffic to. If you include the "AWS_ALIAS_DNS_NAME" attribute when you submit a RegisterInstance request, the "TTL" value is ignored. Always specify a TTL for the service; you can use a service to register instances that create either alias or non-alias records. * **Type** *(string) --* Describes the systems that can be used to discover the service instances.

For example, the value "1516925490.087" represents Friday, January 26, 2018 12:11:30.087 AM. * **CreatorRequestId** *(string) --* A unique string that identifies the request and that allows failed requests to be retried without the risk of running an operation twice. **Exceptions** * "ServiceDiscovery.Client.exceptions.InvalidInput" * "ServiceDiscovery.Client.exceptions.NamespaceNotFound" **Examples** This example gets information about a specified namespace. response = client.get_namespace( Id='ns-e4anhexample0004', ) print(response) Expected Output: { 'Namespace': { 'Arn': 'arn:aws:servicediscovery:us-west-2: 123456789120:namespace/ns-e1tpmexample0001', 'CreateDate': datetime(2018, 11, 18, 21, 17, 12, 6, 322, 0), 'CreatorRequestId': 'example-creator-request-id-0001', 'Description': 'Example.com AWS Cloud Map HTTP Namespace', 'Id': 'ns-e1tpmexample0001', 'Name': 'example-http.com', 'Properties': { 'DnsProperties': { }, 'HttpProperties': { 'HttpName': 'example-http.com', }, }, 'Type': 'HTTP', }, 'ResponseMetadata': { '...': '...', }, } ServiceDiscovery / Client / register_instance register_instance ***************** ServiceDiscovery.Client.register_instance(**kwargs) Creates or updates one or more records and, optionally, creates a health check based on the settings in a specified service. When you submit a "RegisterInstance" request, the following occurs: * For each DNS record that you define in the service that's specified by "ServiceId", a record is created or updated in the hosted zone that's associated with the corresponding namespace. * If the service includes "HealthCheckConfig", a health check is created based on the settings in the health check configuration. * The health check, if any, is associated with each of the new or updated records. Warning: One "RegisterInstance" request must complete before you can submit another request and specify the same service ID and instance ID. For more information, see CreateService. When Cloud Map receives a DNS query for the specified DNS name, it returns the applicable value: * **If the health check is healthy**: returns all the records * **If the health check is unhealthy**: returns the applicable value for the last healthy instance * **If you didn't specify a health check configuration**: returns all the records For the current quota on the number of instances that you can register using the same namespace and using the same service, see Cloud Map quotas in the *Cloud Map Developer Guide*. See also: AWS API Documentation **Request Syntax** response = client.register_instance( ServiceId='string', InstanceId='string', CreatorRequestId='string', Attributes={ 'string': 'string' } ) Parameters: * **ServiceId** (*string*) -- **[REQUIRED]** The ID of the service that you want to use for settings for the instance. * **InstanceId** (*string*) -- **[REQUIRED]** An identifier that you want to associate with the instance. Note the following: * If the service that's specified by "ServiceId" includes settings for an "SRV" record, the value of "InstanceId" is automatically included as part of the value for the "SRV" record. For more information, see DnsRecord > Type. * You can use this value to update an existing instance. * To register a new instance, you must specify a value that's unique among instances that you register by using the same service. * If you specify an existing "InstanceId" and "ServiceId", Cloud Map updates the existing DNS records, if any. If there's also an existing health check, Cloud Map deletes the old health check and creates a new one. Note: The health check isn't deleted immediately, so it will still appear for a while if you submit a "ListHealthChecks" request, for example. Note: Do not include sensitive information in "InstanceId" if the namespace is discoverable by public DNS queries and any "Type" member of "DnsRecord" for the service contains "SRV" because the "InstanceId" is discoverable by public DNS queries. * **CreatorRequestId** (*string*) -- A unique string that identifies the request and that allows failed "RegisterInstance" requests to be retried without the risk of executing the operation twice. You must use a unique "CreatorRequestId" string every time you submit a "RegisterInstance" request if you're registering additional instances for the same namespace and service. "CreatorRequestId" can be any unique string (for example, a date/time stamp). This field is autopopulated if not provided. * **Attributes** (*dict*) -- **[REQUIRED]** A string map that contains the following information for the service that you specify in "ServiceId": * The attributes that apply to the records that are defined in the service. * For each attribute, the applicable value. Warning: Do not include sensitive information in the attributes if the namespace is discoverable by public DNS queries. The following are the supported attribute keys. AWS_ALIAS_DNS_NAME If you want Cloud Map to create an Amazon Route 53 alias record that routes traffic to an Elastic Load Balancing load balancer, specify the DNS name that's associated with the load balancer. For information about how to get the DNS name, see "DNSName" in the topic AliasTarget in the *Route 53 API Reference*. Note the following: * The configuration for the service that's specified by "ServiceId" must include settings for an "A" record, an "AAAA" record, or both. * In the service that's specified by "ServiceId", the value of "RoutingPolicy" must be "WEIGHTED". * If the service that's specified by "ServiceId" includes "HealthCheckConfig" settings, Cloud Map will create the Route 53 health check, but it doesn't associate the health check with the alias record. * Cloud Map currently doesn't support creating alias records that route traffic to Amazon Web Services resources other than Elastic Load Balancing load balancers. * If you specify a value for "AWS_ALIAS_DNS_NAME", don't specify values for any of the "AWS_INSTANCE" attributes. * The "AWS_ALIAS_DNS_NAME" is not supported in the GovCloud (US) Regions. AWS_EC2_INSTANCE_ID *HTTP namespaces only.* The Amazon EC2 instance ID for the instance. If the "AWS_EC2_INSTANCE_ID" attribute is specified, then the only other attribute that can be specified is "AWS_INIT_HEALTH_STATUS". When the "AWS_EC2_INSTANCE_ID" attribute is specified, then the "AWS_INSTANCE_IPV4" attribute will be filled out with the primary private IPv4 address. AWS_INIT_HEALTH_STATUS If the service configuration includes "HealthCheckCustomConfig", you can optionally use "AWS_INIT_HEALTH_STATUS" to specify the initial status of the custom health check, "HEALTHY" or "UNHEALTHY". If you don't specify a value for "AWS_INIT_HEALTH_STATUS", the initial status is "HEALTHY". AWS_INSTANCE_CNAME If the service configuration includes a "CNAME" record, the domain name that you want Route 53 to return in response to DNS queries (for example, "example.com"). This value is required if the service specified by "ServiceId" includes settings for an "CNAME" record. AWS_INSTANCE_IPV4 If the service configuration includes an "A" record, the IPv4 address that you want Route 53 to return in response to DNS queries (for example, "192.0.2.44"). This value is required if the service specified by "ServiceId" includes settings for an "A" record. If the service includes settings for an "SRV" record, you must specify a value for "AWS_INSTANCE_IPV4", "AWS_INSTANCE_IPV6", or both. AWS_INSTANCE_IPV6 If the service configuration includes an "AAAA" record, the IPv6 address that you want Route 53 to return in response to DNS queries (for example, "2001:0db8:85a3:0000:0000:abcd:0001:2345"). This value is required if the service specified by "ServiceId" includes settings for an "AAAA" record. If the service includes settings for an "SRV" record, you must specify a value for "AWS_INSTANCE_IPV4", "AWS_INSTANCE_IPV6", or both. AWS_INSTANCE_PORT If the service includes an "SRV" record, the value that you want Route 53 to return for the port. If the service includes "HealthCheckConfig", the port on the endpoint that you want Route 53 to send requests to. This value is required if you specified settings for an "SRV" record or a Route 53 health check when you created the service. Custom attributes You can add up to 30 custom attributes. For each key-value pair, the maximum length of the attribute name is 255 characters, and the maximum length of the attribute value is 1,024 characters.

The health status updates don't update "InstancesRevision". **Exceptions** * "ServiceDiscovery.Client.exceptions.ServiceNotFound" * "ServiceDiscovery.Client.exceptions.NamespaceNotFound" * "ServiceDiscovery.Client.exceptions.InvalidInput" * "ServiceDiscovery.Client.exceptions.RequestLimitExceeded" **Examples** Example: Discover registered instances response = client.discover_instances( HealthStatus='ALL', MaxResults=10, NamespaceName='example.com', ServiceName='myservice', ) print(response) Expected Output: { 'Instances': [ { 'Attributes': { 'AWS_INSTANCE_IPV4': '172.2.1.3', 'AWS_INSTANCE_PORT': '808', }, 'HealthStatus': 'UNKNOWN', 'InstanceId': 'myservice-53', 'NamespaceName': 'example.com', 'ServiceName': 'myservice', }, ], 'ResponseMetadata': { '...': '...', }, } ServiceDiscovery / Client / create_private_dns_namespace create_private_dns_namespace **************************** ServiceDiscovery.Client.create_private_dns_namespace(**kwargs) Creates a private namespace based on DNS, which is visible only inside a specified Amazon VPC. The namespace defines your service naming scheme. For example, if you name your namespace "example.com" and name your service "backend", the resulting DNS name for the service is "backend.example.com". Service instances that are registered using a private DNS namespace can be discovered using either a "DiscoverInstances" request or using DNS. For the current quota on the number of namespaces that you can create using the same Amazon Web Services account, see Cloud Map quotas in the *Cloud Map Developer Guide*. See also: AWS API Documentation **Request Syntax** response = client.create_private_dns_namespace( Name='string', CreatorRequestId='string', Description='string', Vpc='string', Tags=[ { 'Key': 'string', 'Value': 'string' }, ], Properties={ 'DnsProperties': { 'SOA': { 'TTL': 123 } } } ) Parameters: * **Name** (*string*) -- **[REQUIRED]** The name that you want to assign to this namespace. When you create a private DNS namespace, Cloud Map automatically creates an Amazon Route 53 private hosted zone that has the same name as the namespace. * **CreatorRequestId** (*string*) -- A unique string that identifies the request and that allows failed "CreatePrivateDnsNamespace" requests to be retried without the risk of running the operation twice. "CreatorRequestId" can be any unique string (for example, a date/timestamp). This field is autopopulated if not provided. * **Description** (*string*) -- A description for the namespace. * **Vpc** (*string*) -- **[REQUIRED]** The ID of the Amazon VPC that you want to associate the namespace with. * **Tags** (*list*) -- The tags to add to the namespace. Each tag consists of a key and an optional value that you define. Tags keys can be up to 128 characters in length, and tag values can be up to 256 characters in length. * *(dict) --* A custom key-value pair that's associated with a resource. * **Key** *(string) --* **[REQUIRED]** The key identifier, or name, of the tag. * **Value** *(string) --* **[REQUIRED]** The string value that's associated with the key of the tag. You can set the value of a tag to an empty string, but you can't set the value of a tag to null. * **Properties** (*dict*) -- Properties for the private DNS namespace. * **DnsProperties** *(dict) --* **[REQUIRED]** DNS properties for the private DNS namespace. * **SOA** *(dict) --* **[REQUIRED]** Fields for the Start of Authority (SOA) record for the hosted zone for the private DNS namespace. * **TTL** *(integer) --* **[REQUIRED]** The time to live (TTL) for purposes of negative caching. Return type: dict Returns: **Response Syntax** { 'OperationId': 'string' } **Response Structure** * *(dict) --* * **OperationId** *(string) --* A value that you can use to determine whether the request completed successfully. To get the status of the operation, see GetOperation. **Exceptions** * "ServiceDiscovery.Client.exceptions.InvalidInput" * "ServiceDiscovery.Client.exceptions.NamespaceAlreadyExists" * "ServiceDiscovery.Client.exceptions.ResourceLimitExceeded" * "ServiceDiscovery.Client.exceptions.DuplicateRequest" * "ServiceDiscovery.Client.exceptions.TooManyTagsException" **Examples** Example: Create private DNS namespace response = client.create_private_dns_namespace( CreatorRequestId='eedd6892-50f3-41b2-8af9-611d6e1d1a8c', Name='example.com', Vpc='vpc-1c56417b', ) print(response) Expected Output: { 'OperationId': 'gv4g5meo7ndmeh4fqskygvk23d2fijwa-k9302yzd', 'ResponseMetadata': { '...': '...', }, } ServiceDiscovery / Client / deregister_instance deregister_instance ******************* ServiceDiscovery.Client.deregister_instance(**kwargs) Deletes the Amazon Route 53 DNS records and health check, if any, that Cloud Map created for the specified instance. See also: AWS API Documentation **Request Syntax** response = client.deregister_instance( ServiceId='string', InstanceId='string' ) Parameters: * **ServiceId** (*string*) -- **[REQUIRED]** The ID of the service that the instance is associated with. * **InstanceId** (*string*) -- **[REQUIRED]** The value that you specified for "Id" in the RegisterInstance request. Return type: dict Returns: **Response Syntax** { 'OperationId': 'string' } **Response Structure** * *(dict) --* * **OperationId** *(string) --* A value that you can use to determine whether the request completed successfully. To get the status of the operation, see GetOperation. **Exceptions** * "ServiceDiscovery.Client.exceptions.DuplicateRequest" * "ServiceDiscovery.Client.exceptions.InvalidInput" * "ServiceDiscovery.Client.exceptions.InstanceNotFound" * "ServiceDiscovery.Client.exceptions.ResourceInUse" * "ServiceDiscovery.Client.exceptions.ServiceNotFound" **Examples** Example: Deregister a service instance response = client.deregister_instance( InstanceId='myservice-53', ServiceId='srv-p5zdwlg5uvvzjita', ) print(response) Expected Output: { 'OperationId': '4yejorelbukcjzpnr6tlmrghsjwpngf4-k98rnaiq', 'ResponseMetadata': { '...': '...', }, }
