Does this support SSH private keys with a passphrase?

In my experience you also need to pass in  `-v "$SSH_AUTH_SOCK":"/root/$(basename $SSH_AUTH_SOCK)" -e SSH_AUTH_SOCK="/root/$(basename $SSH_AUTH_SOCK)"` in order to be able to use protected keys. Judging from other issues around use on MacOS this probably isn't available without some extra work to handle Windows/Linux/MacOS use cases, though it is fairly straightforward for Linux.
