official Docker container(s)

[alexanderadam]

First of all: thank you very much for MuMuDVB.

I just wanted to mention that it would be nice to have official Docker container on Docker hub.

Hello Alexander

Thank you for the suggestion but I am new to Docker, can you tell me more how it works and what it does provides ?

Hey Brice,

thank you for your response. Although it's most probably too simple formulated: it's basically a very simple (especially regarding dependencies etc) distribution method that allows encapsulation of applications. It contains everything that is required to run the application and, if it's done well, allows reproducible builds. If persisted data is mounted outside of the container upgrading should not be a problem. And in case you want to remove the application: just remove the container and the data that is in the mounted containers. Nothing else will be touched. Nothing should harm your host system.

This usually requires a Dockerfile that contains the setup to build an image (i.e. install that, add this file, shell commands, …). With the help of the Dockerfile you can create an image which you can make accessible for everyone else (i.e. on Docker hub).

Everyone else can then just chose some parameters if required (i.e. mapping ports, folder mounts, etc) and run the container without having to build it first.

Maybe an example from a related project could help: You can find the container, documentation and Dockerfile of Tvheadend on Docker hub.

And you can simply pull the image with docker pull binhex/arch-tvheadend and run it with the mentioned options of the readme. You can see what it needs to build this containers is declared in it's Dockerfile (the used Linux distribution is usually not so relevant).

I'm not quite sure whether this answers your question but if it didn't: feel free to ask.

Negatives ... Hudge footstep No support to easy build for beginner user. Need more resources.

Here's a sample i'm currently working on, also includes dvblast and some other tools i might need. Please note: the host will have to provide /dev/dvb to the container, docker will not solve any driver issues.

Pushed to dockerhub. Note: this is not an 'official' build.

[alexanderadam]

@maldex awesome! Would it be possible for your to make a PR to integrate the used Dockerfile into the official Repository?

[braice]

Please go ahead with a pull request and I'll merge the Dockerfile !

For an official container, i would not like to include 3rd applications, but for personal use, a army-knife-type-container is great. Trying to figure a nice way for this.
