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.
