Is there any reverse proxy for ssh or any way to reverse proxy ssh through Nginx?

I've been trying for a few weeks and have had no luck at getting anything to work.

I'm looking for something that works this way:

• expose port 22 so no having to use -p xxxx and have different ports for each containers ssh

• be able to ssh to containers as subdomains such as how Nginx reverse proxy does

  • gitea.example.com:22

  • domain2.example.com:22

• keep the current port 80 and 443, I don't want to run ssh through 443

If nothing like this exists any ideas on how to achieve this?

The current reverse proxy I'm using is https://docs.linuxserver.io/images/docker-swag

Thanks for all the information, took me a while to try all the options.

In the end, I was not able to achieve the proxy app.domain.com:22 for several containers for reasons pointed out by w0keson.

I ended up just doing separate ports per container that need ssh.
