LoadBalancer
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.
Contents
- containerName
-
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.
Type: String
Required: No
- containerPort
-
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 thehostPort
of the port mapping.Type: Integer
Required: No
- loadBalancerName
-
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.
Type: String
Required: No
- targetGroupArn
-
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 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.Important
If your service's task definition uses the
awsvpc
network mode, you must chooseip
as the target type, notinstance
. Do this when creating your target groups because tasks that use theawsvpc
network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.Type: String
Required: No
