Class: Aws::ElasticLoadBalancingV2::Client

Inherits:
Seahorse::Client::Base show all
Defined in:
(unknown)

Overview

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

elasticloadbalancingv2 = Aws::ElasticLoadBalancingV2::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

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

Region

You can configure a default region in the following locations:

  • ENV['AWS_REGION']
  • Aws.config[:region]

Go here for a list of supported regions.

Credentials

Default credentials are loaded automatically from the following locations:

  • ENV['AWS_ACCESS_KEY_ID'] and ENV['AWS_SECRET_ACCESS_KEY']
  • Aws.config[:credentials]
  • The shared credentials ini file at ~/.aws/credentials (more information)
  • From an instance profile when running on EC2

You can also construct a credentials object from one of the following classes:

Alternatively, you configure credentials with :access_key_id and :secret_access_key:

# load credentials from disk
creds = YAML.load(File.read('/path/to/secrets'))

Aws::ElasticLoadBalancingV2::Client.new(
  access_key_id: creds['access_key_id'],
  secret_access_key: creds['secret_access_key']
)

Always load your credentials from outside your application. Avoid configuring credentials statically and never commit them to source control.

Instance Method Details

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

Adds the specified SSL server certificate to the certificate list for the specified HTTPS or TLS listener.

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

To get the certificate list for a listener, use DescribeListenerCertificates. To remove certificates from the certificate list for a listener, use RemoveListenerCertificates. To replace the default certificate for a listener, use ModifyListener.

For more information, see SSL Certificates in the Application Load Balancers Guide.

Examples:

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

    The certificate to add. You can specify one certificate per call. Set CertificateArn to the certificate ARN but do not set IsDefault.

Returns:

See Also:

#add_tags(options = {}) ⇒ 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", 
  ],

    {
      key: "project", 
      value: "lima", 
    }, 
    {
      key: "department", 
      value: "digital-media", 
    }, 
  ], 
})

Request syntax with placeholder values

See Also:

#create_listener(options = {}) ⇒ 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.

Examples:

Example: To create an HTTP listener

Example: To create an HTTPS listener


# This example creates an HTTPS listener for the specified load balancer that forwards requests to the specified target group. Note that you must specify an SSL certificate for an HTTPS listener. You can create and manage certificates using AWS Certificate Manager (ACM). Alternatively, you can create a certificate using SSL/TLS tools, get the certificate signed by a certificate authority (CA), and upload the certificate to AWS Identity and Access Management (IAM).

Options Hash (options):

  • :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 protocols are TCP, TLS, UDP, and TCP_UDP.

  • :port (required, Integer)

    The port on which the load balancer is listening.

  • :ssl_policy (String)

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

  • :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.

    To create a certificate list for the listener, use AddListenerCertificates.

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

    The actions for the default rule. The rule must include one forward action or one or more fixed-response actions.

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

    [HTTPS listeners] If the action type is authenticate-oidc, you authenticate users through an identity provider that is OpenID Connect (OIDC) compliant.

    [HTTPS listeners] If the action type is authenticate-cognito, you authenticate users through the user pools supported by Amazon Cognito.

    [Application Load Balancer] If the action type is redirect, you redirect specified client requests from one URL to another.

    [Application Load Balancer] If the action type is fixed-response, you drop specified client requests and return a custom HTTP response.

Returns:

#create_load_balancer(options = {}) ⇒ 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.

Options Hash (options):

  • :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 if you need static IP addresses for your load balancer.

  • :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.

  • :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.

Returns:

#create_rule(options = {}) ⇒ 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.

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/*).

Options Hash (options):

  • :listener_arn (required, String)

    The Amazon Resource Name (ARN) of the listener.

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

    The conditions. Each rule can include zero or one of the following conditions: http-request-method, host-header, path-pattern, and source-ip, and zero or more of the following conditions: http-header and query-string.

  • :priority (required, Integer)

    The rule priority. A listener can\'t have multiple rules with the same priority.

  • :actions (required, Array<Types::Action>)

    The actions. Each rule must include exactly one of the following types of actions: forward, fixed-response, or redirect, and it must be the last action to be performed.

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

    [HTTPS listeners] If the action type is authenticate-oidc, you authenticate users through an identity provider that is OpenID Connect (OIDC) compliant.

    [HTTPS listeners] If the action type is authenticate-cognito, you authenticate users through the user pools supported by Amazon Cognito.

    [Application Load Balancer] If the action type is redirect, you redirect specified client requests from one URL to another.

    [Application Load Balancer] If the action type is fixed-response, you drop specified client requests and return a custom HTTP response.

Returns:

#create_target_group(options = {}) ⇒ 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.

Options Hash (options):

  • :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. 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.

  • :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.

  • :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, the default is TCP. The TCP protocol is supported for health checks only if the protocol of the target group is TCP, TLS, UDP, or TCP_UDP. The 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. The default is traffic-port, which is the port on which each target receives traffic from the load balancer.

  • :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 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 HTTP and HTTPS health checks, the range is 5–300 seconds. 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 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 or HTTPS, 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 or TLS, 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. For target groups with a protocol of HTTP or HTTPS, the default is 2. For target groups with a protocol of TCP or TLS, this value must be the same as the healthy threshold count. If the target type is lambda, the default is 2.

  • :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. You can\'t specify targets for a target group using more than one target type.

    • instance - Targets are specified by instance ID. This is the default value. If the target group protocol is UDP or TCP_UDP, the target type must be instance.

    • ip - Targets are specified 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 - The target groups contains a single Lambda function.

Returns:

See Also:

#delete_listener(options = {}) ⇒ Struct

Deletes the specified listener.

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

Examples:

    Returns an empty response.

See Also:

#delete_load_balancer(options = {}) ⇒ 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:

Options Hash (options):

  • :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 the HTTP and HTTPS protocols. Network Load Balancers support the TCP, TLS, UDP, and TCP_UDP protocols.

  • :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.

  • :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.

    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 or one or more fixed-response actions.

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

    [HTTPS listeners] If the action type is authenticate-oidc, you authenticate users through an identity provider that is OpenID Connect (OIDC) compliant.

    [HTTPS listeners] If the action type is authenticate-cognito, you authenticate users through the user pools supported by Amazon Cognito.

    [Application Load Balancer] If the action type is redirect, you redirect specified client requests from one URL to another.

    [Application Load Balancer] If the action type is fixed-response, you drop specified client requests and return a custom HTTP response.

Returns:

Options Hash (options):

  • :rule_arn (required, String)

    The Amazon Resource Name (ARN) of the rule.

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

    The conditions. Each rule can include zero or one of the following conditions: http-request-method, host-header, path-pattern, and source-ip, and zero or more of the following conditions: http-header and query-string.

  • :actions (Array<Types::Action>)

    The actions. Each rule must include exactly one of the following types of actions: forward, fixed-response, or redirect, and it must be the last action to be performed.

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

    [HTTPS listeners] If the action type is authenticate-oidc, you authenticate users through an identity provider that is OpenID Connect (OIDC) compliant.

    [HTTPS listeners] If the action type is authenticate-cognito, you authenticate users through the user pools supported by Amazon Cognito.

    [Application Load Balancer] If the action type is redirect, you redirect specified client requests from one URL to another.

    [Application Load Balancer] If the action type is fixed-response, you drop specified client requests and return a custom HTTP response.

Options Hash (options):

  • :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 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 ping path that is the destination for the health check request.

  • :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 Application Load Balancers, the range is 5 to 300 seconds. For Network Load Balancers, 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 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.

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

#register_targets(options = {}) ⇒ 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.

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",

    }, 
    {
      id: "i-ceddcd4d", 
    }, 
  ], 
})

Example: To register targets with a target group using port overrides


# This example registers the specified instance with the specified target group using multiple ports. This enables you to register ECS containers on the same instance as targets in the target group.

resp = client.register_targets({
  target_group_arn: "arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-new-targets/3bb63f11dfb0faf9",

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

Waiters polls an API operation until a resource enters a desired state.

Basic Usage

Waiters will poll until they are succesful, they fail by entering a terminal state, or until a maximum number of attempts are made.

# 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 configure waiters by passing a block to #wait_until:

# poll for ~25 seconds
client.wait_until(...) do |w|
  w.max_attempts = 5
  w.delay = 5
end

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(...) do |w|

  # disable max attempts
  w.max_attempts = nil

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

end

Handling Errors

When a waiter is successful, it returns true. When a waiter fails, it raises an error. All errors raised extend from Waiters::Errors::WaiterFailed.

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

Parameters:

  • waiter_name (Symbol)

    The name of the waiter. See #waiter_names for a full list of supported waiters.

  • params (Hash) (defaults to: {})

    Additional request parameters. See the #waiter_names for a list of supported waiters and what request they call. The called request determines the list of accepted parameters.

Yield Parameters:

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.

#waiter_namesArray<Symbol>

Returns the list of supported waiters. The following table lists the supported waiters and the client method they call:

Waiter NameClient MethodDefault Delay:Default Max Attempts:
:load_balancer_available#describe_load_balancers1540
:load_balancer_exists#describe_load_balancers1540
:load_balancers_deleted#describe_load_balancers1540
:target_deregistered#describe_target_health1540
:target_in_service#describe_target_health1540

Returns:
