terraform-aws-cicd

Terraform module to create AWS CodePipeline with CodeBuild for CI/CD

This module supports three use-cases:

1. GitHub -> S3 (build artifact) -> Elastic Beanstalk (running application stack). The module gets the code from a GitHub repository (public or private), builds it by executing the buildspec.yml file from the repository, pushes the built artifact to an S3 bucket, and deploys the artifact to Elastic Beanstalk running one of the supported stacks (e.g. Java, Go, Node, IIS, Python, Ruby, etc.).

   • http://docs.aws.amazon.com/codebuild/latest/userguide/sample-nodejs-hw.html
   • http://docs.aws.amazon.com/codebuild/latest/userguide/sample-go-hw.html

2. GitHub -> ECR (Docker image) -> Elastic Beanstalk (running Docker stack). The module gets the code from a GitHub repository, builds a Docker image from it by executing the buildspec.yml and Dockerfile files from the repository, pushes the Docker image to an ECR repository, and deploys the Docker image to Elastic Beanstalk running Docker stack.

3. GitHub -> ECR (Docker image). The module gets the code from a GitHub repository, builds a Docker image from it by executing the buildspec.yml and Dockerfile files from the repository, and pushes the Docker image to an ECR repository. This is used when we want to build a Docker image from the code and push it to ECR without deploying to Elastic Beanstalk. To activate this mode, don't specify the app and env attributes for the module.

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

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 repository as a module in your existing terraform code:

module "build" {
    source = "cloudposse/cicd/aws"
    # Cloud Posse recommends pinning every module to a specific version
    # version = "x.x.x"
    namespace           = "eg"
    stage               = "staging"
    name                = "app"

    # Enable the pipeline creation
    enabled             = true

    # Elastic Beanstalk
    elastic_beanstalk_application_name = "<(Optional) Elastic Beanstalk application name>"
    elastic_beanstalk_environment_name = "<(Optional) Elastic Beanstalk environment name>"

    # Application repository on GitHub
    github_oauth_token  = "(Required) <GitHub Oauth Token with permissions to access private repositories>"
    repo_owner          = "<GitHub Organization or Person name>"
    repo_name           = "<GitHub repository name of the application to be built and deployed to Elastic Beanstalk>"
    branch              = "<Branch of the GitHub repository>"

    # http://docs.aws.amazon.com/codebuild/latest/userguide/build-env-ref.html
    # http://docs.aws.amazon.com/codebuild/latest/userguide/build-spec-ref.html
    build_image         = "aws/codebuild/standard:2.0"
    build_compute_type  = "BUILD_GENERAL1_SMALL"

    # 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
    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"
   }]
}

Examples

Example: GitHub, NodeJS, S3 and EB

This is an example to build a Node app, store the build artifact to an S3 bucket, and then deploy it to Elastic Beanstalk running Node stack

buildspec.yml file

version: 0.2

phases:
  install:
    commands:
      - echo Starting installation ...
  pre_build:
    commands:
      - echo Installing NPM dependencies...
      - npm install
  build:
    commands:
      - echo Build started on `date`
  post_build:
    commands:
      - echo Build completed on `date`
artifacts:
  files:
    - node_modules/**/*
    - public/**/*
    - routes/**/*
    - views/**/*
    - app.js

Example: GitHub, NodeJS, Docker, ECR and EB

This is an example to build a Docker image for a Node app, push the Docker image to an ECR repository, and then deploy it to Elastic Beanstalk running Docker stack

buildspec.yml file
