filefrog/ssh-git

I like GitHub; I really do!

But sometimes, I just need to run a dumb, throwaway SSH+git containers somewhere on the k8s cluster / docker-compose recipe, for plumbing purposes.

That's what this image is for.

See it on Docker Hub!

Running it on Docker

To run this in your local Docker daemon:

docker run --rm -d --name my-ssh-git \
  -p 2222:22 -e SSH_USER=$USER -e SSH_UID=$UID
  filefrog/ssh-git

The OpenSSH sshd daemon is now spinning in the background.

To use this, you'll first need to exec into the container and run some git init's:

docker exec my-ssh-git -- mkdir -p /repos
docker exec my-ssh-git -- git init --bare /repos/some-repo.git

Then, you can push to it. From a pre-existing git working copy:

git remote add my-ssh-git ssh://localhost:2222/repos/some-repo.git
git push my-ssh-git master

Tada!

Running it on Kubernetes

In many ways, this is a lot easier in Kuberenetes. You can use an init container to pre-initialize the persistent volume with the git repos on it. I've included a deployment manifest, in deploy/k8s/ssh-git.yml that shows off some basic tricks.

Building (and Publishing) to Docker Hub

The Makefile handles building pushing. For jhunt's:

make push

Is all that's needed for release. If you want to build it locally, you can instead use:

make build

If you want to tag it to your own Dockerhub username:

IMAGE=you-at-dockerhub/mbsync make build push

By default, the image is tagged latest. You can supply your own tag via the TAG environment variable:

IMAGE=... TAG=$(date +%Y%m%d%H%M%S) make build push

Happy Hacking!
