Plex server on a VPS Docker setup without port forwarding

by ⋅ Leave a Comment

[ updated 10-30-2016 | Upgraded Plex to plexmediaserver-1.1.4.2757-24ffd60.x86_64.rpm and CentOS ]

Recently I tried setting up a Plex server in a docker container. The first problem was the 127.0.0.1:32400 bind which required logging in locally or port forwarding. After doing this once, I realized that you could use the Preferences.xml file, but that meant that you couldn’t truly automate this/deploy it elegantly in a docker container. And what if you wanted to run other servers — for friends? I finally figured out how to do this in the most elegant way possible.

First – Grab your Unique Plex Access Token

Login at https://app.plex.tv/web/app with your username and password
Open your javascript console (in Chrome: View -> Developer -> JavaScript Console)
and type:
console.log(window.PLEXWEB.myPlexAccessToken);

Note the token, which will look like this: “PZwoXix8vxhQJyrdqAbY”

At this stage DO NOT click log out of your account until you register the new server. Otherwise your token will regenerate.
Once you register the server, it won’t matter after that if the token changes.

You can pull it down by doing:

Docker Swarm Tutorial and Examples

by ⋅ 35 Comments

A bit of background and the “old/normal way”

If you use Docker, you very quickly run into a common question: how do you make Docker work across multiple hosts, datacenters, and different clouds. One of the simplest solutions is Docker Swarm. Docker summarizes it best as “a native clustering for Docker…[which] allows you create and access to a pool of Docker hosts using the full suite of Docker tools.”

One of the biggest benefits to using Docker Swarm is that it provides the standard Docker API, which means that all of the existing Docker management tools (and 3rd party products) just work out of the box as they do with a single host. The only difference is that they now scale transparently over multiple hosts.

After reading up on it HERE and HERE, it was evident that this is a pretty simple service, but it wasn’t 100% clear what went where. After searching around the web, I realized that almost all of the tutorials and examples on Docker Swarm involved either docker-machine or very convoluted examples which did not explain what was happening on which component. With that said, here is a very simple Docker Swarm Tutorial with some practical examples.

Assuming you have a bunch of servers running docker:
vm01 (10.0.0.101), vm02 (10.0.0.102), vm03 (10.0.0.103), vm04 (10.0.0.104)
