Docker setup for Jenkins with docker plugin integration

Why

• If you want to learn Jenkins and try some piplines, this will save you the headache of setting it up yourself
• If you want to integrate Jenkins into your stack, this can be a starter (you just add the SSL stuff, change hostname and you're good to go)
• If you read Installing Jenkins. This is basically it but with the ease of docker-compose and the addition of a reverse proxy

Setup

Note: This assumes that you have port 80 free and unused since we're using it here for HAProxy

• Clone the repo

• Run docker-compose up --build -d

• Verify everything is working

• Go to http://localhost

• If everything works the first page will ask for 1 time password. You can find the password through jenkins container logs

  docker --tail 100 -f mk-jenkins

  paste it in the browser then go through the wizard of setting up an admin user

• Most things will work, but to use Jenkins with full capabilities then using it on a production or any valid server is advised

Features

• Full Jenkins ecosystem with docker integration (the ability for Jenkins to build by using docker)
• Lightweight, all images used are alpine based
• Safe, no containers run using root user
• Easy to setup (development and production)
• Decoupled and extendable, you can pick only the containers you need and throw the rest. Or maybe switch HAProxy with your favourite webserver
• Clean removal (see section below)

Uninstall

• Run docker-compose down -v and it will remove everything related to this repo (even the volumes)
