concourse-up

A Quick setup of a concourse server with Docker Compose with reference from https://github.com/concourse/concourse-docker

Prerequisites

• Certificates and keys generated and exchanged for the web and workers (ref section below)
• Docker is installed (Compose should be installed with it) ref https://docs.docker.com/install/

Setting up Certificates and keys

Run the commands below to create the folders and exchange keys used for communications between the web and worker processes

mkdir -p ~/Dev/docker/keys/web ~/Dev/docker/keys/worker ~/Dev/docker/mounts/concourse/worker

Create ssl keys for concourse host
ssh-keygen -t rsa -f ~/Dev/docker/keys/web/tsa_host_key -N ''

ssh-keygen -t rsa -f ~/Dev/docker/keys/web/session_signing_key -N ''

Create ssl keys for worker
ssh-keygen -t rsa -f ~/Dev/docker/keys/worker/worker_key -N ''

Exchange the keys between the host and workers for communications
cp ~/Dev/docker/keys/worker/worker_key.pub ~/Dev/docker/keys/web/authorized_worker_keys

cp ~/Dev/docker/keys/web/tsa_host_key.pub ~/Dev/docker/keys/worker

Multiple Workers

If more workers are required, do the following:

• Generate ssl keys for the worker in a seperate folder
• copy host key to new worker folder
• copy worker key to host's authorized worker keys
• create a copy of the 'concourse-worker' section in docker-compose.yml, and point the volume to the new worker folder

Usage

Disclaimer: if other folder locations are used other than the ones specified above, update the locations in the docker-compose.yml

• Copy docker-compose.yml file to any file location
• start up the instances with 'docker-compose up' ('docker-compose up -d' for detached processes)
• shutdown and clean up processes with 'docker-compose down'

Note

The disk can get filled up from the docker images generated by the jobs over time, periodically clean out unused images with "docker image prune" command
