Client — AWS SDK for Ruby V2

You are viewing documentation for version 2 of the AWS SDK for Ruby. Version 3 documentation can be found here.

Class: Aws::ElasticLoadBalancingV2::Client 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:

Go here for a list of supported regions.

Credentials

Default credentials are loaded automatically from the following locations:

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:

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.

For more information, see HTTPS listeners in the Application Load Balancers Guide or TLS listeners in the Network Load Balancers Guide.

#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, Gateway Load Balancers, target groups, listeners, and rules.

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.

#create_rule(options = {}) ⇒ 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.

#delete_listener(options = {}) ⇒ Struct

Deletes the specified listener.

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

#delete_load_balancer(options = {}) ⇒ 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.

#delete_rule(options = {}) ⇒ Struct

Deletes the specified rule.

You can't delete the default rule.

#delete_target_group(options = {}) ⇒ Struct

Deletes the specified target group.

You can delete a target group if it is not referenced by any actions. Deleting a target group also deletes any associated health checks. Deleting a target group does not affect its registered targets. For example, any EC2 instances continue to run until you stop or terminate them.

#deregister_targets(options = {}) ⇒ Struct

Deregisters the specified targets from the specified target group. After the targets are deregistered, they no longer receive traffic from the load balancer.

#describe_listener_certificates(options = {}) ⇒ Types::DescribeListenerCertificatesOutput

Describes the default certificate and the certificate list for the specified HTTPS or TLS listener.

If the default certificate is also in the certificate list, it appears twice in the results (once with IsDefault set to true and once with IsDefault set to false).

For more information, see SSL certificates in the Application Load Balancers Guide or Server certificates in the Network Load Balancers Guide.

#describe_listeners(options = {}) ⇒ Types::DescribeListenersOutput

Describes the specified listeners or the listeners for the specified Application Load Balancer, Network Load Balancer, or Gateway Load Balancer. You must specify either a load balancer or one or more listeners.

#describe_rules(options = {}) ⇒ Types::DescribeRulesOutput

Describes the specified rules or the rules for the specified listener. You must specify either a listener or one or more rules.

#describe_tags(options = {}) ⇒ Types::DescribeTagsOutput

Describes the tags for the specified Elastic Load Balancing resources. You can describe the tags for one or more Application Load Balancers, Network Load Balancers, Gateway Load Balancers, target groups, listeners, or rules.

#describe_target_groups(options = {}) ⇒ 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.

#modify_listener(options = {}) ⇒ 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.

#modify_load_balancer_attributes(options = {}) ⇒ Types::ModifyLoadBalancerAttributesOutput

Modifies the specified attributes of the specified Application Load Balancer, Network Load Balancer, or Gateway Load Balancer.

If any of the specified attributes can't be modified as requested, the call fails. Any existing attributes that you do not modify retain their current values.

#modify_rule(options = {}) ⇒ Types::ModifyRuleOutput

Replaces the specified properties of the specified rule. Any properties that you do not specify are unchanged.

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.

#modify_target_group(options = {}) ⇒ Types::ModifyTargetGroupOutput

Modifies the health checks used when evaluating the health state of the targets in the specified target group.

#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.

#remove_listener_certificates(options = {}) ⇒ Struct

Removes the specified certificate from the certificate list for the specified HTTPS or TLS listener.

#remove_tags(options = {}) ⇒ Struct

Removes the specified tags from the specified Elastic Load Balancing resources. You can remove the tags for one or more Application Load Balancers, Network Load Balancers, Gateway Load Balancers, target groups, listeners, or rules.

#set_ip_address_type(options = {}) ⇒ Types::SetIpAddressTypeOutput

Sets the type of IP addresses used by the subnets of the specified Application Load Balancer or Network Load Balancer.

#set_rule_priorities(options = {}) ⇒ Types::SetRulePrioritiesOutput

Sets the priorities of the specified rules.

You can reorder the rules as long as there are no priority conflicts in the new order. Any existing rules that you do not specify retain their current priority.

#set_security_groups(options = {}) ⇒ Types::SetSecurityGroupsOutput

Associates the specified security groups with the specified Application Load Balancer. The specified security groups override the previously associated security groups.

You can't specify a security group for a Network Load Balancer or Gateway Load Balancer.

#set_subnets(options = {}) ⇒ Types::SetSubnetsOutput

Enables the Availability Zones for the specified public subnets for the specified Application Load Balancer or Network Load Balancer. The specified subnets replace the previously enabled subnets.

When you specify subnets for a Network Load Balancer, you must include all subnets that were enabled previously, with their existing configurations, plus any additional subnets.

#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
#waiter_names ⇒ Array<Symbol>

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