I [made a simple container](https://github.com/funkypenguin/git-docker/blob/master/Dockerfile) which just basically executes git in the CWD:
To use it transparently, add an alias for the "git" command:
To use it transparently, add an alias for the "git" command, or just download it with the rest of the [handy aliases](https://raw.githubusercontent.com/funkypenguin/geek-cookbook/master/examples/scripts/gcb-aliases.sh):
```
alias git='docker run -v $PWD:/var/data -v \
/var/data/git-docker/data:/root funkypenguin/git-docker git'
/var/data/git-docker/data/.ssh:/root/.ssh funkypenguin/git-docker git'

## Setup SSH key
docker run -v /var/data/git-docker/data:/root funkypenguin/git-docker ssh-keygen -t ed25519 -f /root/.ssh/id_ed25519
If you plan to actually _push_ using git, you'll need to setup an SSH keypair. You _could_ copy across whatever keypair you currently use, but it's probably more appropriate to generate a specific keypair for this purpose.
Generate your new SSH keypair by running:
```
mkdir -p /var/data/git-docker/data/.ssh
chmod 600 /var/data/git-docker/data/.ssh
docker run -v /var/data/git-docker/data/.ssh:/root/.ssh funkypenguin/git-docker ssh-keygen -t ed25519 -f /root/.ssh/id_ed25519
```
The output will look something like this:
```
Generating public/private ed25519 key pair.
Enter passphrase (empty for no passphrase): Enter same passphrase again: Created directory '/root/.ssh'.
Your identification has been saved in /root/.ssh/id_ed25519.

Now add the contents of /var/data/git-docker/data/.ssh/id_ed25519.pub to your git account, and off you go - just run "git" from your Atomic host as usual, and pretend that you have the client installed!
