When you log into a remote host from your container, the remote host key is unknown to your SSH client inside the container

usually, you're asked to confirm its fingerprint:

The authenticity of host ***** can't be established.
RSA key fingerprint is *****.
Are you sure you want to continue connecting (yes/no)?

But as there is no interactive shell, the SSH client fails.

Two solutions:

  • add the host key in the file ~/.ssh/known_hosts in the container

  • disable host key check (Dangerous as no remote host authentication is performed)

    ssh -o "StrictHostKeyChecking=no" user@host
