docker-autobuild

Description

Docker Hub recently made autobuilds an Pro-only feature. This container does basically the same thing, but on your own infrastructure.

This will:

• Listen for a push webhook from Github
• Look in config.json for a matching config entry
• Pull the repo
• Checkout the correct commit
• Build the container
• Push it to Docker Hub
• Notify you via various notification methods when it's done

Direct trigger

There is also an option to trigger a build directly without a push event.

Send a GET request to: http://mynodeserver:3000/trigger/projectName/branchName. This will follow the same series of events as the webhook, but will checkout the tip of whatever branch is in the URL.

Deployment

The easiest thing to do is deploy this with docker:

• Create a config file somewhere:

curl https://raw.githubusercontent.com/tedkulp/docker-autobuilder/master/config/config.yaml.example > config.yaml

• Modify config file with actual credentials
• Run w/ docker:

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock -p 3000:3000 -v `pwd`/config.json:/app/config/config.json tedkulp/docker-autobuilder:latest

• Create push webhook in repository to point to http://mynodeserver:3000/webhook/github and has a content type of application/json.
• Wait patiently for new docker container to be pushed to Docker Hub

Redis

Docker-autobuilder does require redis for queueing builds. The default hostname is localhost, which can be overridden with the REDIS_HOST environment variable. See the included docker-compose.yaml file for a idea on how to set it up.
