#add_listener_certificates(params = {}) ⇒ Types::AddListenerCertificatesOutput

Adds the specified certificate to the specified secure listener.

If the certificate was already added, the call is successful but the certificate is not added again.

To list the certificates for your listener, use DescribeListenerCertificates. To remove certificates from your listener, use RemoveListenerCertificates.

Examples:

resp = client.add_listener_certificates({
  listener_arn: "ListenerArn", # required
  certificates: [ # required
    {
      certificate_arn: "CertificateArn",
      is_default: false,
    },
  ],
})

Response structure


resp.certificates #=> Array
resp.certificates[0].certificate_arn #=> String
resp.certificates[0].is_default #=> Boolean

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :listener_arn (required, String)

    The Amazon Resource Name (ARN) of the listener.

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

    The certificate to add. You can specify one certificate per call.

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

#add_tags(params = {}) ⇒ Struct

Adds the specified tags to the specified Elastic Load Balancing resource. You can tag your Application Load Balancers, Network Load Balancers, and your target groups.

Each tag consists of a key and an optional value. If a resource already has a tag with the same key, AddTags updates its value.

To list the current tags for your resources, use DescribeTags. To remove tags from your resources, use RemoveTags.

Examples:

Example: To add tags to a load balancer


# This example adds the specified tags to the specified load balancer.

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

})

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :resource_arns (required, Array<String>)

    The Amazon Resource Name (ARN) of the resource.

  • :tags (required, Array<Types::Tag>)

    The tags. Each resource can have a maximum of 10 tags.

end

#create_listener(params = {}) ⇒ Types::CreateListenerOutput

Creates a listener for the specified Application Load Balancer or Network Load Balancer.

To update a listener, use ModifyListener. When you are finished with a listener, you can delete it using DeleteListener. If you are finished with both the listener and the load balancer, you can delete them both using DeleteLoadBalancer.

This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple listeners with the same settings, each call succeeds.

For more information, see Listeners for Your Application Load Balancers in the Application Load Balancers Guide and Listeners for Your Network Load Balancers in the Network Load Balancers Guide.

Parameters:

  • params (Hash) (defaults to: {})

    ({})

Options Hash (params):

  • :load_balancer_arn (required, String)

    The Amazon Resource Name (ARN) of the load balancer.

  • :protocol (required, String)

    The protocol for connections from clients to the load balancer. For Application Load Balancers, the supported protocols are HTTP and HTTPS. For Network Load Balancers, the supported protocol is TCP.

  • :port (required, Integer)

    The port on which the load balancer is listening.

  • :ssl_policy (String)

    [HTTPS listeners] The security policy that defines which ciphers and protocols are supported. The default is the current predefined security policy.

#create_load_balancer(params = {}) ⇒ Types::CreateLoadBalancerOutput

Creates an Application Load Balancer or a Network Load Balancer.

When you create a load balancer, you can specify security groups, public subnets, IP address type, and tags. Otherwise, you could do so later using SetSecurityGroups, SetSubnets, SetIpAddressType, and AddTags.

To create listeners for your load balancer, use CreateListener. To describe your current load balancers, see DescribeLoadBalancers. When you are finished with a load balancer, you can delete it using DeleteLoadBalancer.

For limit information, see Limits for Your Application Load Balancer in the Application Load Balancers Guide and Limits for Your Network Load Balancer in the Network Load Balancers Guide.

This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple load balancers with the same settings, each call succeeds.

For more information, see Application Load Balancers in the Application Load Balancers Guide and Network Load Balancers in the Network Load Balancers Guide.

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.

    [Network 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.

    [Network Load Balancers] You can specify subnets from one or more Availability Zones. You can specify one Elastic IP address per subnet.

  • :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 only route requests from clients with access to the VPC for the load balancer.

    The default is an Internet-facing load balancer.

  • :tags (Array<Types::Tag>)

    One or more tags to assign to the load balancer.

  • :type (String)

    The type of load balancer. The default is application.

  • :ip_address_type (String)

    [Application Load Balancers] 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.

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

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

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.

To view your current rules, use DescribeRules. To update a rule, use ModifyRule. To set the priorities of your rules, use SetRulePriorities. To delete a rule, use DeleteRule.

    ({})

Options Hash (params):

  • :listener_arn (required, String)

    The Amazon Resource Name (ARN) of the listener.

  • :conditions (required, Array<Types::RuleCondition>)

    The conditions. Each condition specifies a field name and a single value.

    If the field name is host-header, you can specify a single host name (for example, my.example.com). A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters. Note that you can include up to three wildcard characters.

    • A-Z, a-z, 0-9

    • - .

      • (matches 0 or more characters)
    • ? (matches exactly 1 character)

    If the field name is path-pattern, you can specify a single path pattern. A path pattern is case sensitive, can be up to 128 characters in length, and can contain any of the following characters. Note that you can include up to three wildcard characters.

    • A-Z, a-z, 0-9

#create_target_group(params = {}) ⇒ Types::CreateTargetGroupOutput

Creates a target group.

To register targets with the target group, use RegisterTargets. To update the health check settings for the target group, use ModifyTargetGroup. To monitor the health of targets in the target group, use DescribeTargetHealth.

To route traffic to the targets in a target group, specify the target group in an action using CreateListener or CreateRule.

To delete a target group, use DeleteTargetGroup.

This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple target groups with the same settings, each call succeeds.

For more information, see Target Groups for Your Application Load Balancers in the Application Load Balancers Guide or Target Groups for Your Network Load Balancers in the Network Load Balancers Guide.

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 (required, 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 protocol is TCP.

  • :port (required, Integer)

    The port on which the targets receive traffic. This port is used unless you specify a port override when registering the target.

  • :vpc_id (required, String)

    The identifier of the virtual private cloud (VPC).

  • :health_check_protocol (String)

    The protocol the load balancer uses when performing health checks on targets. The TCP protocol is supported only if the protocol of the target group is TCP. For Application Load Balancers, the default is HTTP. For Network Load Balancers, the default is TCP.

  • :health_check_port (String)

    The port the load balancer uses when performing health checks on targets. The default is traffic-port, which is the port on which each target receives traffic from the load balancer.

  • :health_check_path (String)

    [HTTP/HTTPS health checks] The ping path that is the destination on the targets for health checks. The default is /.

  • :health_check_interval_seconds (Integer)

    The approximate amount of time, in seconds, between health checks of an individual target. For Application Load Balancers, the range is 5 to 300 seconds. For Network Load Balancers, the supported values are 10 or 30 seconds. The default is 30 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 Application Load Balancers, the range is 2 to 60 seconds and the default is 5 seconds. For Network Load Balancers, this is 10 seconds for TCP and HTTPS health checks and 6 seconds for HTTP health checks.

  • :healthy_threshold_count (Integer)

    The number of consecutive health checks successes required before considering an unhealthy target healthy. For Application Load Balancers, the default is 5. For Network Load Balancers, the default is 3.

  • :unhealthy_threshold_count (Integer)

    The number of consecutive health check failures required before considering a target unhealthy. For Application Load Balancers, the default is 2. For Network Load Balancers, this value must be the same as the healthy threshold count.

  • :matcher (Types::Matcher)

    [HTTP/HTTPS health checks] The HTTP 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. The possible values are instance (targets are specified by instance ID) or ip (targets are specified by IP address). The default is instance. Note that you can't specify targets for a target group using both instance IDs and IP addresses.

    If the target type is ip, 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.

Returns:

#delete_load_balancer(params = {}) ⇒ Struct

Deletes the specified Application Load Balancer or Network Load Balancer and its attached 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",

#describe_target_groups(params = {}) ⇒ Types::DescribeTargetGroupsOutput

Describes the specified target groups or all of your target groups. By default, all target groups are described. Alternatively, you can specify one of the following to filter the results: the ARN of the load balancer, the names of one or more target groups, or the ARNs of one or more target groups.

To describe the targets for a target group, use DescribeTargetHealth. To describe the attributes of a target group, use DescribeTargetGroupAttributes.

Examples:

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.

  • :protocol (String)

    The protocol for connections from clients to the load balancer. Application Load Balancers support HTTP and HTTPS and Network Load Balancers support TCP.

  • :ssl_policy (String)

    [HTTPS listeners] The security policy that defines which protocols and ciphers are supported. For more information, see Security Policies in the Application Load Balancers Guide.

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

    [HTTPS listeners] The default SSL server certificate. You must provide exactly one certificate. To create a certificate list, use AddListenerCertificates.

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

    The actions for the default rule. The rule must include one forward action.

    If the action type is forward, you can specify a single target group. The protocol of the target group must be HTTP or HTTPS for an Application Load Balancer or TCP for a Network Load Balancer.

    If the action type is authenticate-oidc, you can use an identity provider that is OpenID Connect (OIDC) compliant to authenticate users as they access your application.

    If the action type is authenticate-cognito, you can use Amazon Cognito to authenticate users as they access your application.

#register_targets(params = {}) ⇒ Struct

Registers the specified targets with the specified target group.

You can register targets by instance ID or by IP address. 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.

To remove a target from a target group, use DeregisterTargets.

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.waiter_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.
