lnovy/mumble repository overview

⁠Docker! Mumble! PulseAudio!

Run Mumble inside an isolated Docker⁠ container on your Linux desktop! See its sights via X11 forwarding! Hear its sounds through the magic of PulseAudio and SSH tunnels!

Known Issue: While audio works flawlessly during calls and Mumble is perfectly usable, the notification sounds such as call ringing do not work.

⁠Docker index

The easiest method to get Mumble in docker is to download the already prepared image from the official Docker image index repository: lnovy/mumble⁠. Follow further instructions there.

⁠Building Instructions

In case you do not want to download the prepared image, you can built the image yourself using these following instructions.

1. Install PulseAudio Preferences⁠. Debian/Ubuntu users can do this:

    sudo apt-get install paprefs
   

   Copy

2. Launch PulseAudio Preferences, go to the "Network Server" tab, and check the "Enable network access to local sound devices" and "Don't require authentication" checkboxes

3. Restart PulseAudio

    sudo service pulseaudio restart
   

   Copy

   or

    pulseaudio -k
    pulseaudio --start
   

   Copy

   On some distributions, it may be necessary to completely restart your computer. You can confirm that the settings have successfully been applied using the pax11publish command. You should see something like this (the important part is in bold):

   Server: {ShortAlphanumericString}unix:/run/user/1000/pulse/native tcp:YourHostname:4713 tcp6:YourHostname:4713

   Cookie: ReallyLongAlphanumericString

4. Install Docker⁠ if you haven't already

5. Clone this repository and get right in there

    git clone https://github.com/lnovy/docker-mumble-pulseaudio.git && cd docker-mumble-pulseaudio
   

   Copy

6. Build the container

    sudo docker build -t mumble .
   

   Copy

7. Create an entry in your .ssh/config file for easy access. It should look like this:

    Host docker-mumble
      User      docker
      Port      55556
      HostName  127.0.0.1
      RemoteForward 64713 localhost:4713
      ForwardX11 yes
      
   

   Copy

   (Optional) I recommend creating an SSH key without a password to be used to connect to this container. So in case you used a non-standard filename for your SSH key, add this:

      IdentityFile /path/to/your/ssh/key
   

   Copy

8. Run the container and forward the appropriate port

    sudo docker run -d -p 55556:22 mumble
   

   Copy

9. (Optional) Copy an SSH public key

   If you plan to use an SSH key, copy the public key to the docker container using the following command. The password is docker.

    ssh-copy-id -i /path/to/your/public/key.pub docker-mumble
   

   Copy

10. Connect via SSH and launch Mumble using the provided PulseAudio wrapper script

    ssh docker-mumble mumble-pulseaudio
    

    Copy

    In case you didn't copy the SSH public key, the password is docker.

11. Go use Mumble in a safe container!
