Neither pingable nor in any kind of connection making it possible to communicate.Īs this was my last hope, I just modified the interface and the routes for it.įor a start, create a new bridge and get info of the newly created subnet. The bridge as well as the interface behind it got IPs and routes to an unmapped ip subnet reserved for dhcp. Docker bridges, the created bridge interfaces and the system routes. While losing my mind, I’ve looked on the network part again. The goal is having a reverse proxy with ssl, further services behind the reverse proxy.

Containers couldn’t reach the outer network (as in, no update calls etc.).

Running containers on a NAS, which just exposes the possibility by using docker.

Part 1: Using docker and getting crazy with itĪ little recap of what has happened until now: You can find the whole tragedy starting here: Disclaimer: Before you proceed and follow these steps, please keep in mind, that I’m not sure if I’m breaking any internal docker mechanics or opening the gate to hell with this. I’m writing the complete process of how I fixed the network problems in a few steps. I ended up using ENTRYPOINT but I could’ve used CMD in my case as well.Good news in terms of my docker misery. Here are some good links that talk about that: When working with DockerFiles it’s important to know the difference between CMD and ENTRYPOINT directives. etc/sysconfig/PlexMediaServer cd /usr/lib/plexmediaserver. └─ docker run -v /usr/lib/plexmediaserver:/usr/lib/plexmediaserver -v /var/lib/plexmediaserver:/var/lib/plexmediaserver -ulimit memlock=3072000:3072000 -d -it - ĬONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESĤ02f54fc7851 karim/centos-plex:v1 "/usr/bin/plex.sh" 6 seconds ago Up 5 seconds.

Using the init script with a systemd OS was problematic (there are some workarounds but I didn’t go down that path). So let’s start the container and set the main process as the script we created ( /usr/bin/plex.sh) to start the plex service. As soon as I stop the bash shell, the container will stop. etc/sysconfig/PlexMediaServer cd /usr/lib/plex

Instructions on how to create your own bridge are at Building your own bridge. I didn’t need static IPs as I was just playing around with the setup. If you want to assign static IPs to VMs there are a couple third party scripts which allow you to do that:įrom the sound of it, the static IP feature will probably be part of docker soon though.

How to expose docker container’s ip and port to outside docker host without port mapping.

Four ways to connect a docker container to a local network.

There are a couple of cool posts that discuss docker networking: Since Plex uses multicast for DLNA I decided to create a custom bridge which will allow containers direct access to the network.
