kreisys/docker-ssh-exec-wrapper repository overview

The original docker-ssh-exec (https://github.com/mdsol/docker-ssh-exec⁠) has 2 issues:

1. It expects an env variable DOCKER-SSH-KEY to contain the key. Hyphens, unfortunately, are not allowed in most shells.
2. SSH keys contain newlines.

For the life of me I haven't managed to pass an SSH key, with its newline characters through the DOCKER-SSH-KEY variable.

How to use: You'll need to pass your SSH key as one line, all newlines converted to \n, as an environment variable to docker. Example:

docker run -e PRIVATE_SSH_KEY="$(cat ~/.ssh/id_rsa | perl -pe 's/\n/\\n/')" -d kreisys/docker-ssh-exec-wrapper -server
