Terraform Module for CI/CD with AWS Code Pipeline using webhook triggers and Code Build for ECS.

Tip

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform.
Works with Actions, Atlantis, or Spacelift.

Watch demo of using Atmos with Terraform

Example of running atmos to manage infrastructure from our Quick Start tutorial.

For a complete example, see examples/complete.

For automated tests of the complete example using bats and Terratest, see test.

In this example, we'll trigger the pipeline anytime the master branch is updated.

module "ecs_push_pipeline" {
  source = "cloudposse/ecs-codepipeline/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"
  name                  = "app"
  namespace             = "eg"
  stage                 = "staging"
  _oauth_token    = "xxxxxxxxxxxxxx"
  _webhooks_token = "xxxxxxxxxxxxxx"
  repo_owner            = "cloudposse"
  repo_name             = "example"
  branch                = "master"
  service_name          = "example"
  ecs_cluster_name      = "eg-staging-example-cluster"
  privileged_mode       = "true"
}

In this example, we'll trigger anytime a new release is cut by setting the even type to release and using the json_path to exactly match an action of published.

module "ecs_release_pipeline" {
  source = "cloudposse/ecs-codepipeline/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"
  name                        = "app"
  namespace                   = "eg"
  stage                       = "staging"
  _oauth_token          = "xxxxxxxxxxxxxx"
  _webhooks_token       = "xxxxxxxxxxxxxx"
  repo_owner                  = "cloudposse"
  repo_name                   = "example"
  branch                      = "master"
  service_name                = "example"
  ecs_cluster_name            = "eg-staging-example-cluster"
  privileged_mode             = "true"
  _webhook_events       = ["release"]
  webhook_filter_json_path    = "$.action"
  webhook_filter_match_equals = "published"
}

Complete usage can be seen in the terraform-aws-ecs-web-app module.

Here's an example buildspec.yaml. Stick this in the root of your project repository.

version: 0.2
phases:
  pre_build:
    commands:
      - echo Logging in to Amazon ECR...
      - aws --version
      - eval $(aws ecr get-login --region $AWS_DEFAULT_REGION --no-include-email)
      - REPOSITORY_URI=$AWS_ACCOUNT_ID.dkr.ecr.$AWS_REGION.amazonaws.com/$IMAGE_REPO_NAME
      - IMAGE_TAG=$(echo $CODEBUILD_RESOLVED_SOURCE_VERSION | cut -c 1-7)

    commands:
      - echo Build started on `date`
      - echo Building the Docker image...

      - docker pull $REPO_URI:latest || true
      - docker build --cache-from $REPO_URI:latest --tag $REPO_URI:latest --tag $REPO_URI:$IMAGE_TAG .
  post_build:
