Docker - Gitreceive

Gitreceive https://github.com/progrium/gitreceive

Running

docker run --name gitreceive -d -p 22:22 marcellodesales/gitreceive

• The container will expose port 22 (default ssh port) and have a docker volume mounted at /home/git.

Making port binding to other ports makes it harder to connect to the container.

• Make sure the receiver is correctly setup in your host.

docker exec -ti gitreceiver cat /home/git/receiver

Add Keys

To allow someone push to gitreceive, you need to add their public key.

Make sure to review details at https://github.com/progrium/gitreceive

cat ~/.ssh/id_rsa.pub | ssh -i sshkey root@localhost "gitreceive upload-key mdesales"

• The ssh keys are provided for convenience. You must create your own in any serious use.*

Receiving Git changes

• Simply add the server as an origin of a directory with a github repo.

$ git remote add paas git@localhost:myapp

$ git remote show paas
* remote paas
  Fetch URL: git@localhost:myapp
  Push  URL: git@localhost:myapp
  HEAD branch: master
  Remote branch:
    master tracked
  Local ref configured for 'git push':
    master pushes to master (up to date)

• You can now push to the receiver... It will execute the receive script...

$ git push paas master
