Create docker containers on push

Docker build by push

This script makes a build script with a post receive hook. You can use this to build containers when doing a git push to a remote. Basically it will run docker build -t repo on a git push. This is especially handy if you're working in an environment with low internet speeds. It works likes this:

  • Makes a create script on the remote server
  • With the create script you can make a new repository with a buildhook that will run the file ./bin/build in your codebase
  • It passes $1 as branch name, you can use this for deploys or performance checks.

Install the create script on the server, this is responsible for making new repo's to which you can push.

ssh ipa@beers.xyz -- 'wget https://gist.githubusercontent.com/emilebosch/f8fb129ef6028d980fc3b86c3fc1f85f/raw/cff9f5626d2dea42c0d0347cb2022404269bb39e/create && chmod +x create'

This makes a new repo, and shows you the git command to add to you current repo:

 ssh ipa@beers.xyz -- ./create [YOUR REPO NAME]

After this, do a git push!

git push build

It will start a container build and you'll be happy and free.

## Add this file to your code repo under ./bin/build. This is executes on the server by the git push as
## post receive hook. The first argument is the branch name.
