Is there a simple way to rout connections between containers?

 

Back when I hosted my programs on a windows server I created a php script that would send a UDP packet to Murmur (Mumble server) using port 64738 on the same host and get the number of connected users (and some other misc server properties) in a packet as a response. I used this to generate an RSS feed to let users know if anyone was in the server.

 

I've since transitioned to unRAID and have both the web server and Murmur running in containers now. When I attempt to send a packet from the web server container to the Murmur container the connection times out. It fails when using 127.0.0.1, localhost, the local IP, remote IP or the server domain name. I'm assuming the connection is never leaving the web server docker container.

 

I've been able to test the script locally on my PC and I can communicate to the murmur container and Installing murmur on my PC the script is able to request the data fine drom inside of hte container. I'm using hernandito's Apache-PHP-Adminer and coppit's MumbleServer containers if it matters.

 

 

Don't know if this will help at all or not, but if you

ifconfig

at the command line you will see another IP used by dockers.

That did it! The docker0 inet IP works.

 

Thanks trurl.
