Overview

The load balancer configuration to use with a service or task set.

When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.

We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.

A service-linked role is required for services that use multiple target groups. For more information, see [Using service-linked roles] in the *Amazon Elastic Container Service Developer Guide*.

#container_name ⇒ String

The name of the container (as it appears in a container definition) to associate with the load balancer.

You need to specify the container name when configuring the target group for an Amazon ECS load balancer.

  :container_name,
  :container_port)
  SENSITIVE = []
  include Aws::Structure
end

#container_port ⇒ Integer

The port on the container to associate with the load balancer. This port must correspond to a ‘containerPort` in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they’re launched on must allow ingress traffic on the ‘hostPort` of the port mapping.

Returns:

  • (Integer)

#load_balancer_name ⇒ String

The name of the load balancer to associate with the Amazon ECS service or task set.

If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

end

#target_group_arn ⇒ String

The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.

A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.

For services using the ‘ECS` deployment controller, you can specify one or multiple target groups. For more information, see

Registering multiple target groups with a service][1

in the

*Amazon Elastic Container Service Developer Guide*.

For services using the ‘CODE_DEPLOY` deployment controller, you’re required to define two target groups for the load balancer. For more information, see [Blue/green deployment with CodeDeploy] in the *Amazon Elastic Container Service Developer Guide*.

If your service’s task definition uses the ‘awsvpc` network mode, you must choose `ip` as the target type, not `instance`. Do this when creating your target groups because tasks that use the `awsvpc` network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.
