Please allow exposing TCP ports

[rfay]

Describe the bug

Per https://www.gitpod.io/docs/config-ports/

At the moment you can only expose HTTP servers

But so very many applications require us to expose plain non-http TCP ports.

All real computers allow exposing a TCP port. gitpod is awfully close to becoming a real computer! (congrats!)

I can do this with https://github.com/jpillora/chisel doing it by encapsulating the traffic in http packets.

We just announced preview version of Gitpod local companion which allows to tunnel any tcp port: https://www.gitpod.io/blog/local-app please try and give us feedback 🙏🏻

This is an outstanding and exciting feature. Where would you like feedback? (I'm able to get simple ports to work, but ssh access doesn't seem to work;

$ ssh -F /tmp/gitpod_ssh_config amaranth-caterpillar-0wh52qdr
kex_exchange_identification: read: Connection reset by peer

(Edit: This works on a newly created instance, just doesn't work on an existing one. Here's on a new one:

 ssh -F /tmp/gitpod_ssh_config indigo-aardwolf-q3gq1lmk

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

There are a number of things missing in the login, but it definitely works.

Please note that this excellent new feature doesn't address the request in this issue. The idea here would be to actually allow exposing ports on the hostname (or perhaps on a special hostname).

(Edit: This works on a newly created instance, just doesn't work on an existing one. Here's on a new one:

This is likely due to the existing instance running on an older version of the code that doesn't specify the correct port for the SSH server. It used 0 i.e. next available, which the local companion app cannot use.
If you run something like this in the workspace:

ps aux | grep drop

and see '-p :0' not '-p :23001' then that is the reason.

If you elaborate on your use case it would help. I see localhost as a special stable hostname on each you can access any tcp port.
