Troubleshooting

Invalid ECS Service's DeploymentController

If you receive the following error message, ECS Service does not configured DeploymentController to CODE_DEPLOY.

* module.codedeploy.aws_codedeploy_deployment_group.default: 1 error(s) occurred:

* aws_codedeploy_deployment_group.default: InvalidECSServiceException: Deployment group's ECS service must be configured for the external controller.
    status code: 400, request id: 88404497-0379-11e9-88cd-9d6929f0e7ec

You should configure ECS Service's DeploymentController to CODE_DEPLOY.

For Terraform:

resource "aws_ecs_service" "default" {
  ......

  deployment_controller {
    type = "CODE_DEPLOY"
  }
}

For more information, see Amazon ECS Deployment Types in the Amazon Elastic Container Service Developer Guide.
