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

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

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

  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 IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of Aws::InstanceProfileCredentails to enable retries and extended timeouts.
• :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:

  • Aws.config[:region]

• :adaptive_retry_wait_to_fill (Boolean) — default: true —

  Used only in adaptive retry mode. When true, the request will sleep until there is sufficent client side capacity to retry the request. When false, the request will raise a RetryCapacityNotAvailableError and will not retry instead of sleeping.

• :client_side_monitoring (Boolean) — default: false —

  When true, client-side metrics will be collected for all API requests from this client.

• :client_side_monitoring_client_id (String) — default: "" —

  Allows you to provide an identifier for this client which will be attached to all generated client side metrics. Defaults to an empty string.

• :client_side_monitoring_host (String) — default: "127.0.0.1" —

  Allows you to specify the DNS hostname or IPv4 or IPv6 address that the client side monitoring agent is running on, where client metrics will be published via UDP.

• :client_side_monitoring_port (Integer) — default: 31000 —

  Required for publishing client metrics. The port that the client side monitoring agent is running on, where client metrics will be published via UDP.

• :client_side_monitoring_publisher (Aws::ClientSideMonitoring::Publisher) — default: Aws::ClientSideMonitoring::Publisher —

  Allows you to provide a custom client-side monitoring publisher class. By default, will use the Client Side Monitoring Agent Publisher.

• :convert_params (Boolean) — default: true —

  When true, an attempt is made to coerce request parameters into the required types.

• :correct_clock_skew (Boolean) — default: true —

  Used only in standard and adaptive retry modes. Specifies whether to apply a clock skew correction and retry requests with skewed client clocks.

• :disable_host_prefix_injection (Boolean) — default: false —

  Set to true to disable SDK automatically adding host prefix to default service endpoint when available.

• :endpoint (String) —

  The client endpoint is normally constructed from the :region option. You should only configure an :endpoint when connecting to test endpoints. This should be a valid HTTP(S) URI.

• :endpoint_cache_max_entries (Integer) — default: 1000 —

  Used for the maximum size limit of the LRU cache storing endpoints data for endpoint discovery enabled operations. Defaults to 1000.

• :endpoint_cache_max_threads (Integer) — default: 10 —

  Used for the maximum threads in use for polling endpoints to be cached, defaults to 10.

• :endpoint_cache_poll_interval (Integer) — default: 60 —

  When :endpoint_discovery and :active_endpoint_cache is enabled, Use this option to config the time interval in seconds for making requests fetching endpoints information. Defaults to 60 sec.

• :endpoint_discovery (Boolean) — default: false —

  When set to true, endpoint discovery will be enabled for operations when available.

• :log_formatter (Aws::Log::Formatter) — default: Aws::Log::Formatter.default —

  The log formatter.

• :log_level (Symbol) — default: :info —

  The log level to send messages to the :logger at.

• :logger (Logger) —

  The Logger instance to send log messages to. If this option is not set, logging will be disabled.

• :max_attempts (Integer) — default: 3 —

  An integer representing the maximum number attempts that will be made for a single request, including the initial attempt. For example, setting this value to 5 will result in a request being retried up to 4 times. Used in standard and adaptive retry modes.

• :profile (String) — default: "default" —

  Used when loading credentials from the shared credentials file at HOME/.aws/credentials. When not specified, 'default' is used.

• :retry_backoff (Proc) —

  A proc or lambda used for backoff. Defaults to 2**retries * retry_base_delay. This option is only used in the legacy retry mode.

• :retry_base_delay (Float) — default: 0.3 —

  The base delay in seconds used by the default backoff function. This option is only used in the legacy retry mode.

• :retry_jitter (Symbol) — default: :none —

  A delay randomiser function used by the default backoff function. Some predefined functions can be referenced by name - :none, :equal, :full, otherwise a Proc that takes and returns a number. This option is only used in the legacy retry mode.

  @see https://www.awsarchitectureblog.com/2015/03/backoff.html

• :retry_limit (Integer) — default: 3 —

  The maximum number of times to retry failed requests. Only ~ 500 level server errors and certain ~ 400 level client errors are retried. Generally, these are throttling errors, data checksum errors, networking errors, timeout errors, auth errors, endpoint discovery, and errors from expired credentials. This option is only used in the legacy retry mode.

• :retry_max_delay (Integer) — default: 0 —

  The maximum number of seconds to delay between retries (0 for no limit) used by the default backoff function. This option is only used in the legacy retry mode.

• :retry_mode (String) — default: "legacy" —

  Specifies which retry algorithm to use. Values are:

  • 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.

  When :simple_json is enabled, the request parameters hash must be formatted exactly as the DynamoDB API expects.

• :stub_responses (Boolean) — default: false —

  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.

• :validate_params (Boolean) — default: true —

  When true, request parameters are validated before sending the request.

  A proxy to send requests through. Formatted like 'http://proxy.com:123'.

• :http_open_timeout (Float) — default: 15 —

  The number of seconds to wait when opening a HTTP session before raising a Timeout::Error.

• :http_read_timeout (Integer) — default: 60 —

  The default number of seconds to wait for response data. This value can safely be set per-request on the session.

• :http_idle_timeout (Float) — default: 5 —

  The number of seconds a connection is allowed to sit idle before it is considered stale. Stale connections are closed and removed from the pool before making a request.

• :http_continue_timeout (Float) — default: 1 —

  The number of seconds to wait for a 100-continue response before sending the request body. This option has no effect unless the request has "Expect" header set to "100-continue". Defaults to nil which disables this behaviour. This value can safely be set per request on the session.

• :http_wire_trace (Boolean) — default: false —

  When true, HTTP debug output will be sent to the :logger.

• :ssl_verify_peer (Boolean) — default: true —

  When true, SSL peer certificates are verified when establishing a connection.

• :ssl_ca_bundle (String) —

  Full path to the SSL certificate authority bundle file that should be used when verifying peer certificates. If you do not pass :ssl_ca_bundle or :ssl_ca_directory the the system default will be used if available.

• :ssl_ca_directory (String) —

  Full path of the directory that contains the unbundled SSL certificate authority files for verifying peer certificates. If you do not pass :ssl_ca_bundle or :ssl_ca_directory the the system default will be used if available.

Instance Method Details

#describe_services(params = {}) ⇒ Types::DescribeServicesResponse

Returns the metadata for one service or a list of the metadata for all services. Use this without a service code to get the service codes for all services. Use it with a service code, such as AmazonEC2, to get information specific to that service, such as the attribute names available for that service. For example, some of the attribute names available for EC2 are volumeType, maxIopsVolume, operation, locationType, and instanceCapacity10xlarge.
