terraform-ecs-jenkins's Introduction

terraform-ecs-jenkins

Bootstrap AWS account with an ECS cluster running jenkins

This repo contains a Terraform plan to run an Amazon ECS cluster with a private Amazon ECR Docker registry. And Jenkins 2.0 running from a container with ability to build and run more Docker images.

This project is based on material in Capgemini/terraform-amazon-ecs.git but has deviated to a point where a fork no longer makes sense.

Includes -

ECS cluster, launch configuration and autoscaling group
ECR repository for one Docker application
Jenkins container service with an ELB
CloudFormation log group

### Prerequisites

Terraform installed, recommended (>= 0.6.16). Head on over to https://www.terraform.io/downloads.html to grab the latest version.

Install and configure the AWS CLI tools

### Usage

Clone the repo
cp terraform.tfvars.example terraform.tfvars
edit terraform.tfvars with your details
Run the plan -

For a full list of overridable variables see variables.tf
