docker: openssh-server restricted to rsync 🐳

repo: https://github.com/fphammerle/docker-rsync-sshd

docker hub: https://hub.docker.com/r/fphammerle/rsync-sshd

SSH clients are restricted to rsync --server commands via rrsync.

rrsync prefixes /data to all paths (e.g., rsync ... host:/src /backup downloads /data/src).

example 1

$ docker run --name=rsync-sshd -p 2022:22 -e USERS=alice,bob -v rsync-data:/data:ro fphammerle/rsync-sshd
$ docker cp alice-keys rsync-sshd:/home/alice/.ssh/authorized_keys
$ docker cp bob-keys rsync-sshd:/home/bob/.ssh/authorized_keys

example 2

$ docker run --name rsync-sshd \
    --publish 2022:22 --env USERS=alice,bob \
    --volume accessible-data:/data:ro \
    --volume host-keys:/etc/ssh/host_keys \
    --volume alice-ssh-config:/home/alice/.ssh:ro \
    --volume bob-ssh-config:/home/bob/.ssh:ro \
    --init --rm \
