https://github.com/polydawn/siphon-cli https://github.com/polydawn/siphon-cli might address your needs for now. It's just a tiny little wrapper around terminals that shuttles the connection over a unix socket... which in the case of docker, you can put on a mount to access from the host. Author here; I built it to replace that use case of sshd with something that doesn't have the overhead of key management. Of course if you're doing something with network gaps involve, sshd might still be the right answer for you.
