Module: ecs-codepipeline

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

Usage

For a complete example, see examples/complete.

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

Trigger on GitHub Push

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"
  github_oauth_token    = "xxxxxxxxxxxxxx"
  github_webhooks_token = "xxxxxxxxxxxxxx"
  repo_owner            = "cloudposse"
  repo_name             = "example"
  branch                = "master"
  service_name          = "example"
  ecs_cluster_name      = "eg-staging-example-cluster"
  privileged_mode       = "true"
}

Trigger on GitHub Releases

In this example, we'll trigger anytime a new GitHub 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"
  github_oauth_token          = "xxxxxxxxxxxxxx"
  github_webhooks_token       = "xxxxxxxxxxxxxx"
  repo_owner                  = "cloudposse"
  repo_name                   = "example"
  branch                      = "master"
  service_name                = "example"
  ecs_cluster_name            = "eg-staging-example-cluster"
  privileged_mode             = "true"
  github_webhook_events       = ["release"]
  webhook_filter_json_path    = "$.action"
  webhook_filter_match_equals = "published"
}
