Overview

An API client for ElasticLoadBalancingV2. To construct a client, you need to configure a :region and :credentials.

client = Aws::ElasticLoadBalancingV2::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.

#initialize(options) ⇒ Client

Returns a new instance of Client.

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.
  • :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]
    • ENV['AWS_REGION']
    • ENV['AMAZON_REGION']
    • ENV['AWS_DEFAULT_REGION']
    • ~/.aws/credentials
    • ~/.aws/config

  • :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 or custom 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)
  • :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.

    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)

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :name (required, String)

    The name of the load balancer.

    This name must be unique per region per account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, must not begin or end with a hyphen, and must not begin with "internal-".

  • :subnets (Array<String>)

    The IDs of the public subnets. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings.

    [Application Load Balancers] You must specify subnets from at least two Availability Zones.

    [Application Load Balancers on Outposts] You must specify one Outpost subnet.

    [Application Load Balancers on Local Zones] You can specify subnets from one or more Local Zones.

    [Network Load Balancers] You can specify subnets from one or more Availability Zones.

    [Gateway Load Balancers] You can specify subnets from one or more Availability Zones.

  • :subnet_mappings (Array<Types::SubnetMapping>)

    The IDs of the public subnets. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings.

    [Application Load Balancers] You must specify subnets from at least two Availability Zones. You cannot specify Elastic IP addresses for your subnets.

    [Application Load Balancers on Outposts] You must specify one Outpost subnet.

    [Application Load Balancers on Local Zones] You can specify subnets from one or more Local Zones.

    [Network Load Balancers] You can specify subnets from one or more Availability Zones. You can specify one Elastic IP address per subnet if you need static IP addresses for your internet-facing load balancer. For internal load balancers, you can specify one private IP address per subnet from the IPv4 range of the subnet. For internet-facing load balancer, you can specify one IPv6 address per subnet.

    [Gateway Load Balancers] You can specify subnets from one or more Availability Zones. You cannot specify Elastic IP addresses for your subnets.

  • :security_groups (Array<String>)

    [Application Load Balancers] The IDs of the security groups for the load balancer.

  • :scheme (String)

    The nodes of an Internet-facing load balancer have public IP addresses. The DNS name of an Internet-facing load balancer is publicly resolvable to the public IP addresses of the nodes. Therefore, Internet-facing load balancers can route requests from clients over the internet.

    The nodes of an internal load balancer have only private IP addresses. The DNS name of an internal load balancer is publicly resolvable to the private IP addresses of the nodes. Therefore, internal load balancers can route requests only from clients with access to the VPC for the load balancer.

    The default is an Internet-facing load balancer.

    You cannot specify a scheme for a Gateway Load Balancer.

  • :tags (Array<Types::Tag>)

    The tags to assign to the load balancer.

  • :type (String)

    The type of load balancer. The default is application.

  • :ip_address_type (String)

    The type of IP addresses used by the subnets for your load balancer. The possible values are ipv4 (for IPv4 addresses) and dualstack (for IPv4 and IPv6 addresses). Internal load balancers must use ipv4.

  • :customer_owned_ipv_4_pool (String)

    [Application Load Balancers on Outposts] The ID of the customer-owned address pool (CoIP pool).

#create_rule(params = {}) ⇒ Types::CreateRuleOutput

Creates a rule for the specified listener. The listener must be associated with an Application Load Balancer.

Each rule consists of a priority, one or more actions, and one or more conditions. Rules are evaluated in priority order, from the lowest value to the highest value. When the conditions for a rule are met, its actions are performed. If the conditions for no rules are met, the actions for the default rule are performed. For more information, see Listener rules in the Application Load Balancers Guide.

Examples:

Example: To create a rule


# This example creates a rule that forwards requests to the specified target group if the URL contains the specified
# pattern (for example, /img/*).

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :name (required, String)

    The name of the target group.

    This name must be unique per region per account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and must not begin or end with a hyphen.

  • :protocol (String)

    The protocol to use for routing traffic to the targets. For Application Load Balancers, the supported protocols are HTTP and HTTPS. For Network Load Balancers, the supported protocols are TCP, TLS, UDP, or TCP_UDP. For Gateway Load Balancers, the supported protocol is GENEVE. A TCP_UDP listener must be associated with a TCP_UDP target group. If the target is a Lambda function, this parameter does not apply.

  • :protocol_version (String)

    [HTTP/HTTPS protocol] The protocol version. Specify GRPC to send requests to targets using gRPC. Specify HTTP2 to send requests to targets using HTTP/2. The default is HTTP1, which sends requests to targets using HTTP/1.1.

  • :port (Integer)

    The port on which the targets receive traffic. This port is used unless you specify a port override when registering the target. If the target is a Lambda function, this parameter does not apply. If the protocol is GENEVE, the supported port is 6081.

  • :vpc_id (String)

    The identifier of the virtual private cloud (VPC). If the target is a Lambda function, this parameter does not apply. Otherwise, this parameter is required.

  • :health_check_protocol (String)

    The protocol the load balancer uses when performing health checks on targets. For Application Load Balancers, the default is HTTP. For Network Load Balancers and Gateway Load Balancers, the default is TCP. The TCP protocol is not supported for health checks if the protocol of the target group is HTTP or HTTPS. The GENEVE, TLS, UDP, and TCP_UDP protocols are not supported for health checks.

  • :health_check_port (String)

    The port the load balancer uses when performing health checks on targets. If the protocol is HTTP, HTTPS, TCP, TLS, UDP, or TCP_UDP, the default is traffic-port, which is the port on which each target receives traffic from the load balancer. If the protocol is GENEVE, the default is port 80.

  • :health_check_enabled (Boolean)

    Indicates whether health checks are enabled. If the target type is lambda, health checks are disabled by default but can be enabled. If the target type is instance or ip, health checks are always enabled and cannot be disabled.

  • :health_check_path (String)

    [HTTP/HTTPS health checks] The destination for health checks on the targets.

    [HTTP1 or HTTP2 protocol version] The ping path. The default is /.

    [GRPC protocol version] The path of a custom health check method with the format /package.service/method. The default is /AWS.ALB/healthcheck.

  • :health_check_interval_seconds (Integer)

    The approximate amount of time, in seconds, between health checks of an individual target. For TCP health checks, the supported values are 10 and 30 seconds. If the target type is instance or ip, the default is 30 seconds. If the target group protocol is GENEVE, the default is 10 seconds. If the target type is lambda, the default is 35 seconds.

  • :health_check_timeout_seconds (Integer)

    The amount of time, in seconds, during which no response from a target means a failed health check. For target groups with a protocol of HTTP, HTTPS, or GENEVE, the default is 5 seconds. For target groups with a protocol of TCP or TLS, this value must be 6 seconds for HTTP health checks and 10 seconds for TCP and HTTPS health checks. If the target type is lambda, the default is 30 seconds.

  • :healthy_threshold_count (Integer)

    The number of consecutive health checks successes required before considering an unhealthy target healthy. For target groups with a protocol of HTTP or HTTPS, the default is 5. For target groups with a protocol of TCP, TLS, or GENEVE, the default is 3. If the target type is lambda, the default is 5.

  • :unhealthy_threshold_count (Integer)

    The number of consecutive health check failures required before considering a target unhealthy. If the target group protocol is HTTP or HTTPS, the default is 2. If the target group protocol is TCP or TLS, this value must be the same as the healthy threshold count. If the target group protocol is GENEVE, the default is 3. If the target type is lambda, the default is 2.

  • :matcher (Types::Matcher)

    [HTTP/HTTPS health checks] The HTTP or gRPC codes to use when checking for a successful response from a target.

  • :target_type (String)

    The type of target that you must specify when registering targets with this target group. You can't specify targets for a target group using more than one target type.

    • instance - Register targets by instance ID. This is the default value.

    • ip - Register targets by IP address. You can specify IP addresses from the subnets of the virtual private cloud (VPC) for the target group, the RFC 1918 range (10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16), and the RFC 6598 range (100.64.0.0/10). You can't specify publicly routable IP addresses.

    • lambda - Register a single Lambda function as a target.

  • :tags (Array<Types::Tag>)

    The tags to assign to the target group.

Returns:

#delete_listener(params = {}) ⇒ Struct

Deletes the specified listener.

Alternatively, your listener is deleted when you delete the load balancer to which it is attached.

Examples:

Example: To delete a listener


# This example deletes the specified listener.

resp = client.delete_listener({
  listener_arn: "arn:aws:elasticloadbalancing:ua-west-2:123456789012:listener/app/my-load-balancer/50dc6c495c0c9188/f2f7dc8efc522ab2",

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :listener_arn (required, String)

    The Amazon Resource Name (ARN) of the listener.

Returns:

end

#delete_load_balancer(params = {}) ⇒ Struct

Deletes the specified Application Load Balancer, Network Load Balancer, or Gateway Load Balancer. Deleting a load balancer also deletes its listeners.

You can't delete a load balancer if deletion protection is enabled. If the load balancer does not exist or has already been deleted, the call succeeds.

Deleting a load balancer does not affect its registered targets. For example, your EC2 instances continue to run and are still registered to their target groups. If you no longer need these EC2 instances, you can stop or terminate them.

Examples:

Example: To delete a load balancer


# This example deletes the specified load balancer.

resp = client.delete_load_balancer({
  load_balancer_arn: "arn:aws:elasticloadbalancing:us-west-2:123456789012:loadbalancer/app/my-load-balancer/50dc6c495c0c9188",

#modify_listener(params = {}) ⇒ Types::ModifyListenerOutput

Replaces the specified properties of the specified listener. Any properties that you do not specify remain unchanged.

Changing the protocol from HTTPS to HTTP, or from TLS to TCP, removes the security policy and default certificate properties. If you change the protocol from HTTP to HTTPS, or from TCP to TLS, you must add the security policy and default certificate properties.

To add an item to a list, remove an item from a list, or update an item in a list, you must provide the entire list. For example, to add an action, specify a list with the current actions plus the new action.

Examples:

Example: To change the default action for a listener


# This example changes the default action for the specified listener.

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :listener_arn (required, String)

    The Amazon Resource Name (ARN) of the listener.

  • :port (Integer)

    The port for connections from clients to the load balancer. You cannot specify a port for a Gateway Load Balancer.

  • :protocol (String)

    The protocol for connections from clients to the load balancer. Application Load Balancers support the HTTP and HTTPS protocols. Network Load Balancers support the TCP, TLS, UDP, and TCP_UDP protocols. You can’t change the protocol to UDP or TCP_UDP if dual-stack mode is enabled. You cannot specify a protocol for a Gateway Load Balancer.

  • :ssl_policy (String)

    [HTTPS and TLS listeners] The security policy that defines which protocols and ciphers are supported.

    For more information, see Security policies in the Application Load Balancers Guide or Security policies in the Network Load Balancers Guide.

  • :certificates (Array<Types::Certificate>)

    [HTTPS and TLS listeners] The default certificate for the listener. You must provide exactly one certificate. Set CertificateArn to the certificate ARN but do not set IsDefault.

  • :default_actions (Array<Types::Action>)

    The actions for the default rule.

  • :alpn_policy (Array<String>)

    [TLS listeners] The name of the Application-Layer Protocol Negotiation (ALPN) policy. You can specify one policy name. The following are the possible values:

    • HTTP1Only

    • HTTP2Only

    • HTTP2Optional

    • HTTP2Preferred

    • None

    For more information, see ALPN policies in the Network Load Balancers Guide.

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :target_group_arn (required, String)

    The Amazon Resource Name (ARN) of the target group.

  • :health_check_protocol (String)

    The protocol the load balancer uses when performing health checks on targets. The TCP protocol is supported for health checks only if the protocol of the target group is TCP, TLS, UDP, or TCP_UDP. The GENEVE, TLS, UDP, and TCP_UDP protocols are not supported for health checks.

    With Network Load Balancers, you can't modify this setting.

  • :health_check_port (String)

    The port the load balancer uses when performing health checks on targets.

  • :health_check_path (String)

    [HTTP/HTTPS health checks] The destination for health checks on the targets.

    [HTTP1 or HTTP2 protocol version] The ping path. The default is /.

    [GRPC protocol version] The path of a custom health check method with the format /package.service/method. The default is /AWS.ALB/healthcheck.

  • :health_check_enabled (Boolean)

    Indicates whether health checks are enabled.

  • :health_check_interval_seconds (Integer)

    The approximate amount of time, in seconds, between health checks of an individual target. For TCP health checks, the supported values are 10 or 30 seconds.

    With Network Load Balancers, you can't modify this setting.

  • :health_check_timeout_seconds (Integer)

    [HTTP/HTTPS health checks] The amount of time, in seconds, during which no response means a failed health check.

    With Network Load Balancers, you can't modify this setting.

  • :healthy_threshold_count (Integer)

    The number of consecutive health checks successes required before considering an unhealthy target healthy.

  • :unhealthy_threshold_count (Integer)

    The number of consecutive health check failures required before considering the target unhealthy. For target groups with a protocol of TCP or TLS, this value must be the same as the healthy threshold count.

  • :matcher (Types::Matcher)

    [HTTP/HTTPS health checks] The HTTP or gRPC codes to use when checking for a successful response from a target.

    With Network Load Balancers, you can't modify this setting.

#register_targets(params = {}) ⇒ Struct

Registers the specified targets with the specified target group.

If the target is an EC2 instance, it must be in the running state when you register it.

By default, the load balancer routes requests to registered targets using the protocol and port for the target group. Alternatively, you can override the port for a target when you register it. You can register each EC2 instance or IP address with the same target group multiple times using different ports.

With a Network Load Balancer, you cannot register instances by instance ID if they have the following instance types: C1, CC1, CC2, CG1, CG2, CR1, CS1, G1, G2, HI1, HS1, M1, M2, M3, and T1. You can register instances of these types by IP address.

Examples:

Example: To register targets with a target group


# This example registers the specified instances with the specified target group.

resp = client.register_targets({
  target_group_arn: "arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/73e2d6bc24d8a067",

#wait_until(waiter_name, params = {}, options = {}) {|w.waiter| ... } ⇒ Boolean

Polls an API operation until a resource enters a desired state.

Basic Usage

A waiter will call an API operation until:

  • It is successful
  • It enters a terminal state
  • It makes the maximum number of attempts

In between attempts, the waiter will sleep.

# polls in a loop, sleeping between attempts
client.wait_until(waiter_name, params)

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You can pass configuration as the final arguments hash.

# poll for ~25 seconds
client.wait_until(waiter_name, params, {
  max_attempts: 5,
  delay: 5,
})

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
client.wait_until(waiter_name, params, {

  # disable max attempts
  max_attempts: nil,

  # poll for 1 hour, instead of a number of attempts
  before_wait: -> (attempts, response) do
    throw :failure if Time.now - started_at > 3600
  end
})

Handling Errors

When a waiter is unsuccessful, it will raise an error. All of the failure errors extend from Waiters::Errors::WaiterFailed.

begin
  client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

Valid Waiters

The following table lists the valid waiter names, the operations they call, and the default :delay and :max_attempts values.

waiter_name params :delay :max_attempts
load_balancer_available #describe_load_balancers 15 40
load_balancer_exists #describe_load_balancers 15 40
load_balancers_deleted #describe_load_balancers 15 40
target_deregistered #describe_target_health 15 40
target_in_service #describe_target_health 15 40

Parameters:

  • waiter_name (Symbol)
  • params (Hash) (defaults to: {})

    ({})

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :max_attempts (Integer)
  • :delay (Integer)
  • :before_attempt (Proc)
  • :before_wait (Proc)

Yields:

  • (w.waiter)

Returns:

  • (Boolean)

    Returns true if the waiter was successful.

Raises:

  • (Errors::FailureStateError)

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

  • (Errors::TooManyAttemptsError)

    Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.

  • (Errors::UnexpectedError)

    Raised when an error is encounted while polling for a resource that is not expected.

  • (Errors::NoSuchWaiterError)

    Raised when you request to wait for an unknown state.
