Git-crypt in docker.
This was build after frustration in getting git-crypt installed in my arch installation, after keep failing with openssl compilation errors.
Clone the repo locally and cd to it.
Check if you want to change the uid and gid in the Dockerfile to your own (so files created by git-crypt will be owned by you and not root) and build the image:
$ docker build -t [some_name] .
Create a shell wrapper git-crypt as /usr/local/bin/git-crypt (hopefully this path is in your $PATH):
#!/bin/bash -e
exec docker run -i -v $PWD:/repo [some_name] "$@"
NOTE: To be honest this hack has problems adding and using gpg users, that I didn't have time debugging. In my use case, using symmetric keys, it is working fine though:
$ mkdir test-repo
$ cd test-repo/
$ git init
Initialized empty Git repository in /mnt/data/projects/sources/test-repo/.git
