Terraform module to create AWS CodeBuild project for AWS CodePipeline.


This project is part of our comprehensive "SweetOps" approach towards DevOps.

Terraform Open Source Modules

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Usage

IMPORTANT: We do not pin modules to versions in our examples because of the difficulty of keeping the versions in the documentation in sync with the latest released versions. We highly recommend that in your code you pin the version to the exact version you are using so that your infrastructure remains stable, and update versions in a systematic way so that they do not catch you by surprise.

Also, because of a bug in the Terraform registry (hashicorp/terraform#21417), the registry shows many of our inputs as required when in fact they are optional. The table below correctly indicates which inputs are required.

Include this module in your existing terraform code:

module "build" {
    source              = "git::https://github.com/cloudposse/terraform-aws-codebuild.git?ref=master"
    namespace           = "eg"
    stage               = "staging"
    name                = "app"

    # https://docs.aws.amazon.com/codebuild/latest/userguide/build-env-ref-available.html
    build_image         = "aws/codebuild/standard:2.0"
    build_compute_type  = "BUILD_GENERAL1_SMALL"
    build_timeout       = 60

    # These attributes are optional, used as ENV variables when building Docker images and pushing them to ECR
    # For more info:
    # http://docs.aws.amazon.com/codebuild/latest/userguide/sample-docker.html
    # https://www.terraform.io/docs/providers/aws/r/codebuild_project.html

    privileged_mode     = true
    aws_region          = "us-east-1"
    aws_account_id      = "xxxxxxxxxx"
    image_repo_name     = "ecr-repo-name"
    image_tag           = "latest"

    # Optional extra environment variables
    environment_variables = [{
        name  = "JENKINS_URL"
        value = "https://jenkins.example.com"
      },
      {
        name  = "COMPANY_NAME"
        value = "Amazon"
      },
      {
        name = "TIME_ZONE"
        value = "Pacific/Auckland"

      }]
}
