Configure continious syncronization to Docker container

Run Docker container in background

docker run -itd -p127.0.0.1:30022:22 -p127.0.0.1:30873:873 --name ubu1 --hostname ubu1 ubuntu

Append your host public key to container's authorized_keys. This file must be owned by user and mode be 600 -rw-------
It is expected you already have SSH key.

docker exec ubu1 mkdir -p /root/.ssh/
docker exec ubu1 bash -c "echo $(cat ~/.ssh/id_rsa.pub) >> /root/.ssh/authorized_keys"

Run autorsync

autorsync $PWD --rsh='ssh -p30022' root@localhost:$PWD

Troubleshoting

  1. Assert sshd is running

    docker exec ubu1 /usr/sbin/sshd

    Logs in foreground could help better

    docker exec -it ubu1 /usr/sbin/sshd -d

  2. Check connection

    ssh -Tnvvp30022 root@localhost

  3. chmod and chown for authorized_keys in docker

    chown root:root /root/.ssh/authorized_keys
chmod 600       /root/.ssh/authorized_keys

Fish Shell

You may also want to install and use Fish Shell instead of Bash:

apt update
apt install software-properties-common
apt-add-repository ppa:fish-shell/release-3
apt update
apt install fish
