buildkitd to listen to ssh:// addr

[fenollp]

I'm trying to get builkitd to listen to ssh:// connections in much the same way that docker allows setting DOCKER_HOST client side.

I'm not setting --addr for builkitd and passing the buildkitd socket to buildctl works.

Should I be doing something with BUILDKIT_HOST?
If this ssh:// thing is specific to docker, where should I look at to implement it for builkitd?

Thanks

SSH is a dialer side feature. On daemon side you still listen to UNIX socket and we have a command buildctl dial-stdio that is a helper to dial into the socket and redirect its own studio to it.

So on the dialer side, when user wants to connect to ssh://myhost dialer would run ssh myhost -- buildctl dial-stdio.

Take a look at docker/cli#889 for the docker cli implementation. Our current connection helpers are in https://github.com/moby/buildkit/tree/master/client/connhelper
