RancherOS and sound module (missing /dev/snd)

RancherOS
21

I haven’t followed this thread for a while … the release you are referring to must be ros 0.5, isn’t it?
If I am not mistaken that is released, right? would you mind to post the link to the “page in the docs” here?

Is there any update on this? I’m seriously interested into moving my desktop to RancherOS which would make it a lot easier for me to target RancherOS on all our server machines. Getting sound, xwindows, etc… working and somewhat supported would be a huge step forward for us.

RancherOS ros service / compose misses two features I need to build my RancherOS Desktop: tmpfs, group_add.

kernel-extra service is required!
sudo ros s enable kernel-extras
sudo ros s list

...
enabled  kernel-extras
...

My example service files:

base service (xorg, dbus, volumeicon)

#version: '2'
#services:
  xorg:
    image: "dengleros/xorg"
    container_name: xorg
    hostname: xorg
    privileged: true
    read_only: true
    restart: always
    environment:
    - DISPLAY=:0
    tmpfs:
    - /var/log
    volumes:
    - dengleros-tmp:/tmp
    # Workaround missing tmpfs
    - /var/log
    user: root

  dbus:
    image: "dengleros/dbus"
    container_name: dbus
    hostname: dbus
    read_only: true
    restart: always
    labels:                   
    - io.rancher.os.after=xorg
    volumes:
    - dengleros-varlibdbus:/var/lib/dbus
    - dengleros-varrundbus:/var/run/dbus
    - dengleros-homeuserdbus:/home/user/.dbus
    # xorg volume
    - dengleros-tmp:/tmp

  volumeicon:
    image: "dengleros/volumeicon"
    container_name: volumeicon
    hostname: volumeicon
    restart: always
    labels:
    - io.rancher.os.after=xorg
    environment:
    - DISPLAY=:0
    devices:
    - /dev/snd:/dev/snd
    volumes:
    - dengleros-volumeicon:/home/user/.config/volumeicon
    # Volume xorg
    - dengleros-tmp:/tmp

Fluxbox DE
xterm with (user-)docker access.

#version: '2'
#services:
  fluxbox:                                   
    image: "dengleros/fluxbox"               
    container_name: fluxbox                  
    hostname: fluxbox                        
    restart: unless-stopped                  
    labels:                                  
    - io.rancher.os.after=xorg               
    - io.rancher.os.after=dbus               
    environment:                             
    - DISPLAY=:0                             
    volumes:                  
    - dengleros-homeuserfluxbox:/home/user/.fluxbox
    - /usr/bin/docker:/usr/bin/docker              
    - /var/run/docker.sock:/var/run/docker.sock    
    # Volumes xorg and dbus                        
    - dengleros-varlibdbus:/var/lib/dbus           
    - dengleros-varrundbus:/var/run/dbus           
    - dengleros-homeuserdbus:/home/user/.dbus      
    - dengleros-tmp:/tmp

Chromium browser (needs compose group_add…)

docker run -dti --name chromium --hostname chromium --group-add audio --group-add video --volumes-from xorg --volumes-from dbus -e DISPLAY=:0 --shm-size=512m  --device /dev/snd --device /dev/dri --user root dengleros/chromium

Should boot to a fluxbox DE with xterm and (user-)docker access. Images are alpine based, but it’s possible to mix up different distributions (I started with a volumeicon @ debian and moved to alpine later).

The images are testing and not optimized, but works fine for me :wink:
Privileges should be reduced and user moved from root to a normal user…
I created a simple login screen (i3lock), but isn’t added with this example above.

Do you know when compose v2 syntax with group_add and tmpfs will be available at RancherOS (ros service)? group_add and tmpfs could be merged to docker-compose, but maybe not released yet…?

Any one created a wifi container with a gui / applet like wicd / connman-ui / wpa_gui?

wlan0 is inside my container (–net=host), but no interfaces listed in wpa_gui… I don’t know why the wpa_gui can’t find wlan0 interface…

25

Don’t know why… works fine now and moved to RancherOS service.

  wpagui:
    image: "dengleros/wpagui"
    container_name: wpagui
#    hostname: wpagui
    restart: always
    net: host
    cap_add:
    - NET_ADMIN
    labels:
    - io.rancher.os.after=xorg
    environment:
    - DISPLAY=:0
    - QT_X11_NO_MITSHM=1
    - QT_GRAPHICSSYSTEM=native
    volumes:
    - dengleros-tmp:/tmp

DenglerOS Desktop with separated xorg, dbus, volumeicon, wpa_gui, fluxbox and sound / wlan. As desktop fluxbox and manually started chromium browser and additional applications (terminator, keepassx, atom, …).
