Overview

An API client for ServiceDiscovery. To construct a client, you need to configure a :region and :credentials.

client = Aws::ServiceDiscovery::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the developer guide.

See #initialize for a full list of supported configuration options.

Parameters:

  • options (Hash)

Options Hash (options):

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials. This can be an instance of any one of the following classes:

    • Aws::Credentials - Used for configuring static, non-refreshing credentials.

    • Aws::SharedCredentials - Used for loading static credentials from a shared file, such as ~/.aws/config.

    • Aws::AssumeRoleCredentials - Used when you need to assume a role.

    • Aws::AssumeRoleWebIdentityCredentials - Used when you need to assume a role after providing credentials via the web.

    • Aws::SSOCredentials - Used for loading credentials from AWS SSO using an access token generated from aws login.

    • Aws::ProcessCredentials - Used for loading credentials from a process that outputs to stdout.

    • Aws::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • Aws::ECSCredentials - Used for loading credentials from instances running in ECS.

    • Aws::CognitoIdentityCredentials - Used for loading credentials from the Cognito Identity service.

    When :credentials are not configured directly, the following locations will be searched for credentials:

    • Aws.config[:credentials]
    • The :access_key_id, :secret_access_key, and :session_token options.
    • ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    • ~/.aws/credentials
    • ~/.aws/config
    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of Aws::InstanceProfileCredentails or Aws::ECSCredentials to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV['AWS_EC2_METADATA_DISABLED'] to true.
  • :region (required, String) —

    The AWS region to connect to. The configured :region is used to determine the service :endpoint. When not passed, a default :region is searched for in the following locations:

    • legacy - The pre-existing retry behavior. This is default value if no retry mode is provided.

    • standard - A standardized set of retry rules across the AWS SDKs. This includes support for retry quotas, which limit the number of unsuccessful retries a client can make.

    • adaptive - An experimental retry mode that includes all the functionality of standard mode along with automatic client side throttling. This is a provisional mode that may change behavior in the future.

  • :secret_access_key (String)
  • :session_token (String)
  • :simple_json (Boolean) — default: false —

    Disables request parameter conversion, validation, and formatting. Also disable response data type conversions. This option is useful when you want to ensure the highest level of performance by avoiding overhead of walking request parameters and response data structures.

    Causes the client to return stubbed responses. By default fake responses are generated and returned. You can specify the response data to return or errors to raise by calling ClientStubs#stub_responses. See ClientStubs for more information.

    Please note When response stubbing is enabled, no HTTP requests are made, and retries are disabled.

  • :token_provider (Aws::TokenProvider) —

    A Bearer Token Provider. This can be an instance of any one of the following classes:

    • Aws::StaticTokenProvider - Used for configuring static, non-refreshing tokens.

    • Aws::SSOTokenProvider - Used for loading tokens from AWS SSO using an access token generated from aws login.

    When :token_provider is not configured directly, the Aws::TokenProviderChain will be used to search for tokens configured for your profile in shared configuration files.

Instance Method Details

#create_http_namespace(params = {}) ⇒ Types::CreateHttpNamespaceResponse

Creates an HTTP namespace. Service instances registered using an HTTP namespace can be discovered using a DiscoverInstances request but can't be discovered 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.

Examples:

Example: CreateHttpNamespace example


# This example creates an HTTP namespace.

resp = client.create_http_namespace({
  creator_request_id: "example-creator-request-id-0001", 
  description: "Example.com AWS Cloud Map HTTP Namespace", 
  name: "example-http.com", 
})

resp.to_h outputs the following:

Options Hash (params):

  • :name (required, String) —

    The name that you want to assign to this namespace.

  • :creator_request_id (String) —

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

    A suitable default value is auto-generated. You should normally not need to pass this option.**

  • :description (String) —

    A description for the namespace.

  • :tags (Array<Types::Tag>) —

    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.

#create_private_dns_namespace(params = {}) ⇒ Types::CreatePrivateDnsNamespaceResponse

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.

Examples:

Example: Example: Create private DNS namespace


# Example: Create private DNS namespace

  • :creator_request_id (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).

    A suitable default value is auto-generated. You should normally not need to pass this option.**

  • :description (String) —

    A description for the namespace.

  • :vpc (required, String) —

    The ID of the Amazon VPC that you want to associate the namespace with.

#create_public_dns_namespace(params = {}) ⇒ Types::CreatePublicDnsNamespaceResponse

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.

The CreatePublicDnsNamespace API operation is not supported in the Amazon Web Services GovCloud (US) Regions.

#create_service(params = {}) ⇒ Types::CreateServiceResponse

Creates a service. This action defines the configuration for the following entities:

  • For public and private DNS namespaces, one of the following combinations of DNS records in Amazon Route 53:

    • A

    • AAAA

    • A and AAAA

    • SRV

    • CNAME

  • Optionally, a health check

After you create the service, you can submit a RegisterInstance request, and Cloud Map uses the values in the configuration to create the specified entities.

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.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :name (required, String) —

    The name that you want to assign to the service.

    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).

    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.

  • :namespace_id (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.

  • :creator_request_id (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).

    A suitable default value is auto-generated. You should normally not need to pass this option.**

  • :description (String) —

    A description for the service.

  • :dns_config (Types::DnsConfig) —

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

  • :health_check_config (Types::HealthCheckConfig) —

    Public DNS and HTTP namespaces only. A complex type that contains settings for an optional Route 53 health check. If you specify settings for a health check, Cloud Map associates the health check with all the Route 53 DNS records that you specify in DnsConfig.

    If you specify a health check configuration, you can specify either HealthCheckCustomConfig or HealthCheckConfig but not both.

    For information about the charges for health checks, see Cloud Map Pricing.

  • :health_check_custom_config (Types::HealthCheckCustomConfig) —

    A complex type that contains information about an optional custom health check.

    If you specify a health check configuration, you can specify either HealthCheckCustomConfig or HealthCheckConfig but not both.

    You can't add, update, or delete a HealthCheckCustomConfig configuration from an existing service.

  • :tags (Array<Types::Tag>) —

    The tags to add to the service. 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.

  • :type (String) —

    If present, specifies that the service instances are only discoverable using the DiscoverInstances API operation. No DNS records is registered for the service instances. The only valid value is HTTP.

Returns:

If there are instances that match both the filters specified in both the QueryParameters parameter and this parameter, all of these instances are returned. Otherwise, the filters are ignored, and only instances that match the filters that are specified in the QueryParameters parameter are returned.

  • :health_status (String) —

    The health status of the instances that you want to discover. This parameter is ignored for services that don't have a health check configured, and all instances are returned.

    HEALTHY

    Returns healthy instances.

    UNHEALTHY

    Returns unhealthy instances.

    ALL

    Returns all instances.

    The ID of the service that the instance is associated with.

  • :instances (Array<String>) —

    An array that contains the IDs of all the instances that you want to get the health status for.

    If you omit Instances, Cloud Map returns the health status for all the instances that are associated with the specified service.

    To get the IDs for the instances that you've registered by using a specified service, submit a ListInstances request.

  • :max_results (Integer) —

    The maximum number of instances that you want Cloud Map to return in the response to a GetInstancesHealthStatus request. If you don't specify a value for MaxResults, Cloud Map returns up to 100 instances.

  • :next_token (String) —

    For the first GetInstancesHealthStatus request, omit this value.

    If more than MaxResults instances match the specified criteria, you can submit another GetInstancesHealthStatus request to get the next group of results. Specify the value of NextToken from the previous response in the next request.

#register_instance(params = {}) ⇒ Types::RegisterInstanceResponse

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.

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.

Examples:

Example: Example: Register Instance


# Example: Register Instance

resp = client.register_instance({
  attributes: {
    "AWS_INSTANCE_IPV4" => "172.2.1.3", 
    "AWS_INSTANCE_PORT" => "808", 
  }, 
  creator_request_id: "7a48a98a-72e6-4849-bfa7-1a458e030d7b", 
  instance_id: "myservice-53", 
  service_id: "srv-p5zdwlg5uvvzjita", 
})

resp.to_h outputs the following:

  operation_id: "4yejorelbukcjzpnr6tlmrghsjwpngf4-k95yg2u7", 
}

Request syntax with placeholder values


resp = client.register_instance({
  service_id: "ResourceId", # required
  instance_id: "InstanceId", # required
  creator_request_id: "ResourceId",
  attributes: { # required
    "AttrKey" => "AttrValue",
  },
})

Response structure


resp.operation_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :service_id (required, String) —

    The ID of the service that you want to use for settings for the instance.

  • :instance_id (required, String) —

    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.

      The health check isn't deleted immediately, so it will still appear for a while if you submit a ListHealthChecks request, for example.

    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.

  • :creator_request_id (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).

    A suitable default value is auto-generated. You should normally not need to pass this option.**

  • :attributes (required, Hash<String,String>) —

    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.

    Do not include sensitive information in the attributes if the namespace is discoverable by public DNS queries.

    Supported attribute keys include the following:

    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.

    • Auto naming 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.

    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 total size of all provided attributes (sum of all keys and values) must not exceed 5,000 characters.

Response structure


resp.operation_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :id (required, String) —

    The ID of the namespace being updated.

  • :updater_request_id (String) —

    A unique string that identifies the request and that allows failed UpdatePublicDnsNamespace requests to be retried without the risk of running the operation twice. UpdaterRequestId can be any unique string (for example, a date/timestamp).

    A suitable default value is auto-generated. You should normally not need to pass this option.**

  • :namespace (required, Types::PublicDnsNamespaceChange) —

    Updated properties for the public DNS namespace.

Returns:

def update_public_dns_namespace(params = {}, options = {})
  req = build_request(:update_public_dns_namespace, params)
  req.send_request(options)
end

#update_service(params = {}) ⇒ Types::UpdateServiceResponse

Submits a request to perform the following operations:

  • Update the TTL setting for existing DnsRecords configurations

  • Add, update, or delete HealthCheckConfig for a specified service

    You can't add, update, or delete a HealthCheckCustomConfig configuration.

For public and private DNS namespaces, note the following:

  • If you omit any existing DnsRecords or HealthCheckConfig configurations from an UpdateService request, the configurations are deleted from the service.

  • If you omit an existing HealthCheckCustomConfig configuration from an UpdateService request, the configuration isn't deleted from the service.

When you update settings for a service, Cloud Map also updates the corresponding settings in all the records and health checks that were created by using the specified service.

Examples:

Example: UpdateService Example


# This example submits a request to replace the DnsConfig and HealthCheckConfig settings of a specified service.

resp = client.update_service({
  id: "srv-e4anhexample0004", 
  service: {
    dns_config: {
      dns_records: [
        {
          ttl: 60, 
          type: "A", 
        }, 
      ], 
    }, 
    health_check_config: {
      failure_threshold: 2, 
      resource_path: "/", 
      type: "HTTP", 
    }, 
  }, 
})

resp.to_h outputs the following:
{
  operation_id: "m35hsdrkxwjffm3xef4bxyy6vc3ewakx-jdn3y5g5", 
}
