# [Openssh-server](https://www.openssh.com/) is a sandboxed environment that
# allows ssh access without giving keys to the entire server. Giving ssh access
# via private key often means giving full access to the server. This container
# creates a limited and sandboxed environment that others can ssh into. The
# users only have access to the folders mapped and the processes running inside
# this container.
