ServiceDiscovery

Table of Contents

Client

class ServiceDiscovery.Client

A low-level client representing Amazon Route 53 Auto Naming (ServiceDiscovery):

client = session.create_client('servicediscovery')

These are the available methods:

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
create_private_dns_namespace(**kwargs)

Creates a private namespace based on DNS, which will be 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 will be backend.example.com . You can associate more than one service with the same namespace.

    Name='string',
    CreatorRequestId='string',
    Description='string',
    DnsConfig={

        'Type': 'HTTP'|'HTTPS'|'TCP',
        'ResourcePath': 'string',
        'FailureThreshold': 123
    }
)
Parameters
  • Name (string) --

    [REQUIRED]

    The name that you want to assign to the service.

  • CreatorRequestId (string) --

    A unique string that identifies the request and that allows failed CreateService requests to be retried without the risk of executing the operation twice. CreatorRequestId can be any unique string, for example, a date/time stamp.

    This field is autopopulated if not provided.

  • Description (string) -- A description for the service.
  • DnsConfig (dict) --

    [REQUIRED]

    A complex type that contains information about the records that you want Route 53 to create when you register an instance.

    • NamespaceId (string) -- [REQUIRED]

      The ID of the namespace to use for DNS configuration.

    • RoutingPolicy (string) --

      The routing policy that you want to apply to all records that Route 53 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 the service includes configurations for one A record and a health check, and 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 the service includes configurations for one A record and a health check, and 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) -- [REQUIRED]

      An array that contains one DnsRecord object for each record that you want Route 53 to create when you register an instance.

      • (dict) --

        A complex type that contains information about the records that you want Route 53 to create when you register an instance.

        • Type (string) -- [REQUIRED]

          The type of the resource, which indicates the type of value that Route 53 returns in response to DNS queries.

          Note the following:

          • A, AAAA, and SRV records: You can specify settings for a maximum of one A, one AAAA, and one SRV record. You can specify them in any combination.
          • CNAME records: If you specify CNAME for Type , you can't define any other records. This is a limitation of DNS—you can't create a CNAME record and any other type of record that has the same name as a CNAME record.
          • Alias records: If you want Route 53 to create an alias record when you register an instance, specify A or AAAA for Type .
          • All records: You specify settings other than TTL and Type when you register an instance.

          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 RegisterInstanceRequest$Attributes .
          • 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:

          test.backend.example.com

          If you specify settings for an SRV record and if you specify values for AWS_INSTANCE_IPV4 , AWS_INSTANCE_IPV6 , or both in the RegisterInstance request, Route 53 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.

        • 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 AWS 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 namespaces only. A complex type that contains settings for an optional health check. If you specify settings for a health check, Route 53 associates the health check with all the records that you specify in DnsConfig .

    For information about the charges for health checks, see Route 53 Pricing .

    • 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.

      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 for which your endpoint will return an HTTP status code of 2xx or 3xx when the endpoint is healthy, such as the file /docs/route53-health-check.html . Route 53 automatically adds the DNS name for the service and a leading forward slash (/ ) character.

    • 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 vice versa. For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Route 53 Developer Guide .

Response Structure

  • (dict) --

    • Instance (dict) --

      A complex type that contains information about a specified instance.

      • Id (string) --

        An identifier that you want to associate with the instance. Note the following:

        • If the service that is 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 is unique among instances that you register by using the same service.
        • If you specify an existing InstanceId and ServiceId , Route 53 updates the existing records. If there's also an existing health check, Route 53 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.

      • 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.

      • Attributes (dict) --

        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.

        Supported attribute keys include the following:

        • AWS_ALIAS_DNS_NAME : If you want Route 53 to create an alias record that routes traffic to an Elastic Load Balancing load balancer, specify the DNS name that is associated with the load balancer. For information about how to get the DNS name, see "DNSName" in the topic AliasTarget . Note the following:
          • The configuration for the service that is specified by ServiceId must include settings for an A record, an AAAA record, or both.
          • In the service that is specified by ServiceId , the value of RoutingPolicy must be WEIGHTED .
          • If the service that is specified by ServiceId includes HealthCheckConfig settings, Route 53 will create the health check, but it won't associate the health check with the alias record.
          • Auto naming currently doesn't support creating alias records that route traffic to AWS resources other than ELB load balancers.
          • If you specify a value for AWS_ALIAS_DNS_NAME , don't specify values for any of the AWS_INSTANCE attributes.
        • 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. Either AWS_INSTANCE_IPV4 or AWS_INSTANCE_IPV6 is required if the service includes settings for an SRV record.
        • 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. Either AWS_INSTANCE_IPV4 or AWS_INSTANCE_IPV6 is required if the service includes settings for an SRV record.
        • AWS_INSTANCE_PORT : If the service includes an SRV record, the value that you want Route 53 to return for the port. In addition, if the service includes HealthCheckConfig , the port on the endpoint that you want Route 53 to send requests to. For more information, see CreateService . This value is required if you specified settings for an SRV record when you created the service.

Response Structure

  • (dict) --
    • Service (dict) --

      A complex type that contains information about the service.

      • Id (string) --

        The ID that Route 53 assigned to the service when you created it.

      • Arn (string) --

        The Amazon Resource Name (ARN) that Route 53 assigns to the service when you create it.

      • Name (string) --

        The name of the service.

      • Description (string) --

        The description of 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 have been deleted are not included in the count.

      • DnsConfig (dict) --

        A complex type that contains information about the records that you want Route 53 to create when you register an instance.

        • NamespaceId (string) --

          The ID of the namespace to use for DNS configuration.

        • RoutingPolicy (string) --

          The routing policy that you want to apply to all records that Route 53 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 the service includes configurations for one A record and a health check, and 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 the service includes configurations for one A record and a health check, and 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 record that you want Route 53 to create when you register an instance.

          • (dict) --

            A complex type that contains information about the records that you want Route 53 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.

              Note the following:

              • A, AAAA, and SRV records: You can specify settings for a maximum of one A, one AAAA, and one SRV record. You can specify them in any combination.
              • CNAME records: If you specify CNAME for Type , you can't define any other records. This is a limitation of DNS—you can't create a CNAME record and any other type of record that has the same name as a CNAME record.
              • Alias records: If you want Route 53 to create an alias record when you register an instance, specify A or AAAA for Type .
              • All records: You specify settings other than TTL and Type when you register an instance.

              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 RegisterInstanceRequest$Attributes .
              • 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:

              test.backend.example.com

              If you specify settings for an SRV record and if you specify values for AWS_INSTANCE_IPV4 , AWS_INSTANCE_IPV6 , or both in the RegisterInstance request, Route 53 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.

            • 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 AWS 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 namespaces only. A complex type that contains settings for an optional health check. If you specify settings for a health check, Route 53 associates the health check with all the records that you specify in DnsConfig .

        For information about the charges for health checks, see 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.

          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 for which your endpoint will return an HTTP status code of 2xx or 3xx when the endpoint is healthy, such as the file /docs/route53-health-check.html . Route 53 automatically adds the DNS name for the service and a leading forward slash (/ ) character.

        • 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 vice versa. For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Route 53 Developer Guide .

      • 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 executing the operation twice. CreatorRequestId can be any unique string, for example, a date/time stamp.

get_waiter(waiter_name)
list_instances(**kwargs)

register_instance(**kwargs)

Creates or updates one or more records and optionally a health check based on the settings in a specified service. When you submit a RegisterInstance request, Amazon Route 53 does the following:

  • For each DNS record that you define in the service specified by ServiceId , creates or updates a record in the hosted zone that is associated with the corresponding namespace
  • Creates or updates a health check based on the settings in the health check configuration, if any, for the service
  • Associates the health check, if any, with each of the 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 Route 53 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 IP address of the last healthy instance
  • If you didn't specify a health check configuration : returns all the records

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 records and health check that Route 53 will create.

  • InstanceId (string) --

    [REQUIRED]

    An identifier that you want to associate with the instance. Note the following:

    • If the service that is 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 is unique among instances that you register by using the same service.
    • If you specify an existing InstanceId and ServiceId , Route 53 updates the existing records. If there's also an existing health check, Route 53 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.

  • 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.

    Supported attribute keys include the following:

    AWS_ALIAS_DNS_NAME

    If you want Route 53 to create an alias record that routes traffic to an Elastic Load Balancing load balancer, specify the DNS name that is associated with the load balancer. For information about how to get the DNS name, see "DNSName" in the topic AliasTarget .

    Note the following:

    • The configuration for the service that is specified by ServiceId must include settings for an A record, an AAAA record, or both.
    • In the service that is specified by ServiceId , the value of RoutingPolicy must be WEIGHTED .
    • If the service that is specified by ServiceId includes HealthCheckConfig settings, Route 53 will create the health check, but it won't associate the health check with the alias record.
    • Auto naming currently doesn't support creating alias records that route traffic to AWS resources other than ELB load balancers.
    • If you specify a value for AWS_ALIAS_DNS_NAME , don't specify values for any of the AWS_INSTANCE attributes.
    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. Either AWS_INSTANCE_IPV4 or AWS_INSTANCE_IPV6 is required if the service includes settings for an SRV record.

    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. Either AWS_INSTANCE_IPV4 or AWS_INSTANCE_IPV6 is required if the service includes settings for an SRV record.

    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 when you created the service.

    • OperationId (string) --

      A value that you can use to determine whether the request completed successfully. To get the status of the operation, see GetOperation .

update_service(**kwargs)

Submits a request to perform the following operations:

  • Add or delete DnsRecords configurations
  • Update the TTL setting for existing DnsRecords configurations
  • Add, update, or delete HealthCheckConfig for a specified service

You must specify all DnsRecords configurations (and, optionally, HealthCheckConfig ) that you want to appear in the updated service. Any current configurations that don't appear in an UpdateService request are deleted.

When you update the TTL setting for a service, Amazon Route 53 also updates the corresponding settings in all the records and health checks that were created by using the specified service.

    The ID of the service that you want to update.

  • Service (dict) --

    [REQUIRED]

    A complex type that contains the new settings for the service.

    • Description (string) --

      A description for the service.

    • DnsConfig (dict) -- [REQUIRED]

      A complex type that contains information about the records that you want Route 53 to create when you register an instance.

      • DnsRecords (list) -- [REQUIRED]

        An array that contains one DnsRecord object for each record that you want Route 53 to create when you register an instance.

        • (dict) --

          A complex type that contains information about the records that you want Route 53 to create when you register an instance.

          • Type (string) -- [REQUIRED]

            The type of the resource, which indicates the type of value that Route 53 returns in response to DNS queries.

            Note the following:

            • A, AAAA, and SRV records: You can specify settings for a maximum of one A, one AAAA, and one SRV record. You can specify them in any combination.
            • CNAME records: If you specify CNAME for Type , you can't define any other records. This is a limitation of DNS—you can't create a CNAME record and any other type of record that has the same name as a CNAME record.
            • Alias records: If you want Route 53 to create an alias record when you register an instance, specify A or AAAA for Type .
            • All records: You specify settings other than TTL and Type when you register an instance.

            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 RegisterInstanceRequest$Attributes .
            • 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:

            test.backend.example.com

            If you specify settings for an SRV record and if you specify values for AWS_INSTANCE_IPV4 , AWS_INSTANCE_IPV6 , or both in the RegisterInstance request, Route 53 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.

          • 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 AWS 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 namespaces only. A complex type that contains settings for an optional health check. If you specify settings for a health check, Amazon Route 53 associates the health check with all the records that you specify in DnsConfig .

      A and AAAA records

      If DnsConfig includes configurations for both A and AAAA records, Route 53 creates a health check that uses the IPv4 address to check the health of the resource. If the endpoint that is specified by the IPv4 address is unhealthy, Route 53 considers both the A and AAAA records to be unhealthy.

      CNAME records

      You can't specify settings for HealthCheckConfig when the DNSConfig includes CNAME for the value of Type . If you do, the CreateService request will fail with an InvalidInput error.

      Request interval

      The health check uses 30 seconds as the request interval. This is the number of seconds between the time that each Route 53 health checker gets a response from your endpoint and the time that it sends the next health check request. A health checker in each data center around the world sends your endpoint a health check request every 30 seconds. On average, your endpoint receives a health check request about every two seconds. Health checkers in different data centers don't coordinate with one another, so you'll sometimes see several requests per second followed by a few seconds with no health checks at all.

      Health checking regions

      Health checkers perform checks from all Route 53 health-checking regions. For a list of the current regions, see Regions .

      Alias records

      When you register an instance, if you include the AWS_ALIAS_DNS_NAME attribute, Route 53 creates an alias record. Note the following:

      • Route 53 automatically sets EvaluateTargetHealth to true for alias records. When EvaluateTargetHealth is true, the alias record inherits the health of the referenced AWS resource. such as an ELB load balancer. For more information, see EvaluateTargetHealth .
      • If you include HealthCheckConfig and then use the service to register an instance that creates an alias record, Route 53 doesn't create the health check.

      For information about the charges for health checks, see Route 53 Pricing .

      • 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.

        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 for which your endpoint will return an HTTP status code of 2xx or 3xx when the endpoint is healthy, such as the file /docs/route53-health-check.html . Route 53 automatically adds the DNS name for the service and a leading forward slash (/ ) character.

      • 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 vice versa. For more information, see How Route 53 Determines Whether an Endpoint Is Healthy in the Route 53 Developer Guide .
