Terraform module which creates CodeDeploy for ECS resources on AWS.

Description

Provision Applications, Deployment Groups and AWS CodeDeploy IAM Role.

This module provides recommended settings:

• ECS Blue/Green deployment
• Enable automatically rollback

Usage

Minimal

module "codedeploy" {
  source                     = "git::https://github.com/tmknom/terraform-aws-codedeploy-for-ecs.git?ref=tags/1.2.0"
  name                       = "example"
  ecs_cluster_name           = "${var.ecs_cluster_name}"
  ecs_service_name           = "${var.ecs_service_name}"
  lb_listener_arns           = ["${var.lb_listener_arns}"]
  blue_lb_target_group_name  = "${var.blue_lb_target_group_name}"
  green_lb_target_group_name = "${var.green_lb_target_group_name}"
}

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.
