January 7, 201511 yr Is it possible to have some of my docker containers get a different IP address on my local subnet? I'm starting to run into some port conflicts with different apps I'm turning up in docker containers. ? Docker let's you reassign ports for containers pretty easily. Can you give us an example of where that isn't working for you?
January 7, 201511 yr Is it possible to have some of my docker containers get a different IP address on my local subnet? I'm starting to run into some port conflicts with different apps I'm turning up in docker containers. The usual way to deal with port conflicts is to remap the ports. That feature is already available in the built-in docker manager.
January 7, 201511 yr Author I have 2 apps that must run on the same public port. I cannot reassign them as the devices are attempting to connect to them on these pre-defined ports.

January 7, 201511 yr I had the same issue trying to run 2 Plex dockers. Inexplicably Plex hard codes port 32400 so a separate IP address is required for outside connectivity. There is a solution in Pipework, but it was too complicated for me to set up. According to this article other options may be in progress but aren't ready for prime time. The easy solution for me was to run the second Plex server in a VM.
January 7, 201511 yr Start the first container for Plex, goto settings, go to server, go to connect, and here you can change the port Plex uses.

I think plex says you can't though. https://support.plex.tv/hc/en-us/articles/200931138 Important: While you can choose any valid WAN/external port number you desire, the mapping for the LAN/internal port must always be 32400.
January 7, 201511 yr Oh wow, never checked out support. Hmm... Gonna need to research this further. Eric and I were talking docker and vms and networking today. In short, other than Plex, are there any other containers that you can't get around this using port mappings in docker?

In short, other than Plex, are there any other containers that you can't get around this using port mappings in docker? There surely is PlexConnect that Needs both 80 and 443. EDIT: You can kind'of workaround it using the Reverse-Proxy docker (by smdion) and some advanced Apache config for the reverse settings. ie: I can serve 80 and 443 to Apple TV from the Apache Reverse and forward to different Ports in PlexConnect with a specific SSL cert and still use same IP and Ports to serve different SSL Cert for my own Domain. The trick is to identify the ServerName in the config (atv.plexconnect + trailers.apple.com for PlexConnect) or just no ServerName at all for my own domain.

Yes you can remap in the PlexConnect config, but you absolutely need a proxy because Apple TV need to think it speak on Port 80&443. Using the ReverseProxy, it work.

January 7, 201511 yr i've got two nics on my m/board and i've wondered whether it were possible to have two network bridges, one on each nic.

It could use different mode but then you have to find a way to remap the other network services that plex uses internally. I forget which it is, maybe it was network discover. But it's mentioned in one of the Docker files I was looking at for plex. I haven't had a chance to experiment in my own docker with this to see if I could keep it to the simpler mode.

I'm 99% sure plex connect could do bridged, but it does need 80/443 or a working reverse proxy config.
January 7, 201511 yr OK, I think Brit had another feature request out there about networking that was related to this. Will be looking into this.

January 7, 201511 yr Also.. is changing the unRAID WebUI port something we want to add into the WebUI? I don't know if that'll ever be supported with emhttp since that process cannot be restarted but you can change the webgui port today by adding a -p 8000 (if say you wanted to move it from the default port 80 to port 8000) to the emhttp line in /boot/config/go: #!/bin/bash # Start the Management Utility /usr/local/sbin/emhttp -p 8000 & Then just reboot unRAID to have that port change go in to effect.

Yeah I was just thinking with a few dockers running on port 80 it may be easier for some users to have it in the WebUI.
January 8, 201511 yr lxc (underlying container tech) can certainly do containers on separate / discrete IP's. Hopefully docker will provide an interface to that at some point.
April 16, 201511 yr Is there any change on getting different IP for docker? IP address or Port? If it's IP address you're on about, may I ask why?
April 16, 201511 yr off topic but not to off So no one here runs more that one nic on their unraid system? I am stuck with two dual port intel PCI gbit cards because they would not work on correctly with pfSense box and i thought about installing them on the unraid and see what kind of monkey business i could get into.
