SSH config

This container runs sshd. By mapping port 22 to a load balancer / host you can ssh to the host.

You can map valid ssh keys to /home/ubuntu/.ssh/authorized_keys

The following files can be mapped.

/etc/ssh/ssh_config # sshd configuration file.
/etc/ssh/ssh_host_ed25519_key.pub # ed25519 host public key
/etc/ssh/ssh_host_ed25519_key # ed25519 host private key
/etc/ssh/ssh_host_rsa_key.pub # rsa host public key
/etc/ssh/ssh_host_rsa_key # rsa host private key
/etc/ssh/ssh_host_ecdsa_key.pub # ecdsa host public key
/etc/ssh/ssh_host_ecdsa_key # ecdsa private key
