Allow virtual hosts to expose multiple ports about nginx-proxy HOT 10 CLOSED

Multiple ports are not currently supported in the current template but there is no reason why you could not have the template do that though. For 443, you probably need to get SSL certs setup as well. SSL support is not implemented yet.

Hi,

Can you please explain with more detail how I could achieve this? For example, I want to use the Docker image "sameersbn/gitlab" that exposes the ports 80 and 22 and have a "jenkins" container also. So the "nginx-proxy" should be able to redirect "gitlab.myserver.com" on port 80 and 22 and "jenkins.myserver.com" on port 8080 only.

Thank in advance for your help.

nginx-proxy won't work for proxying port 22 (ssh). For your web traffic on port 80 and 8080, you would just set an env variable VIRTUAL_HOST=gitlab.myserver.com and VIRTUAL_HOST=jenkins.myserver.com on the appropriate containers and run nginx-proxy on the same host. Provided your DNS is setup to point to those domain names to your host, nginx-proxy will route the traffice accordingly. When you start your jenkins and gitlab containers, don't bind them to the host port 80/8080, just let docker assign a host port.

Thanks a lot for the answer, it's very clear!

So, for the SSH, I'll just let "-p 22:22", so that the gitlab container exposes the port directly. I think that should work :)

Cheers!

That should work although you may need to change your host's SSH port to avoid a conflict.

One last question, to make sure I fully understand (I am kind of a newbie on all this):

So, if my gitlab container exposes the port like "-p 22:22", then I won't be able to connect to my physical server (let's say "myserver.com ") on SSH port 22 anymore, because the connection will actually be redirected towards the container. The solution is, as you suggested, to have a setting like "-p 10022:22" instead of the exact port binding.

I hope I got this right. Thanks again for your help ;)

from nginx-proxy.

Yes. Either the container uses port 22 on the host or the host's SSH daemon does. Only one can use it though.

Great! I really appreciate it!

@jwilder - am I right in thinking this won't solve the problem though, seeing as @cosminonnet needs to expose both ports 80 and 10022 on the same container?

Is this possible without changing the nginx configuration template?

from nginx-proxy.

Sorry, only just realised that you were suggesting routing port 22 directly without going through nginx-proxy. Good idea!
