terraform-aws-jenkins

Introduction

terraform-aws-jenkins is a Terraform module to build a Docker image with Jenkins, save it to an ECR repo, and deploy to Elastic Beanstalk running Docker.

This is an enterprise-ready, scalable and highly-available architecture and the CI/CD pattern to build and deploy Jenkins.

The module uses these open-source Cloud Posse modules:

Features

The module will create the following AWS resources:

Elastic Beanstalk Application
Elastic Beanstalk Environment with Docker stack to run the Jenkins master
ECR repository to store the Jenkins Docker image
EFS filesystem to store Jenkins config and jobs (it will be mounted to a directory on the EC2 host, and then to the Docker container)
CodePipeline with CodeBuild to build and deploy Jenkins so even Jenkins itself follows the CI/CD pattern
CloudFormation stack to run a DataPipeline to automatically backup the EFS to S3
CloudFormation stack for SNS notifications about the status of each backup

After all of the AWS resources are created,

CodePipeline will:

Get the specified Jenkins repo from GitHub, e.g. https://github.com/cloudposse/jenkins
Build a Docker image from it
Save the Docker image to the ECR repo
Deploy the Docker image from the ECR repo to Elastic Beanstalk running Docker stack
Monitor the GitHub repo for changes and re-run the steps above if new commits are pushed into it

DataPipeline will run on the specified schedule and will backup all Jenkins files to an S3 bucket by doing the following:

Spawn an EC2 instance
Mount the EFS filesystem to a directory on the EC2 instance
Backup the directory to an S3 bucket
Notify about the status of the backup (Success or Failure) via email
Destroy the EC2 instance

Usage

For complete examples, see examples.
