BT Sensors plugin from Docker

seems like it does not work out of the box, seeing dbus permission denied errors - has somebody already cracked this and has BT sensors working in SK server running in Docker? @naugehyde or maybe @Karl-Erik Gustafsson ?

Been running plugin in docker long times and no issues.

Teppo KurkiOP•3mo ago

the plugin did not start properly until i added volume mapping /var/run/dbus:/var/run/dbus

Karl-Erik Gustafsson•3mo ago

Was about to ask volume mapping. That is needed there.

now the plugin starts but server log shows stuff like

Check that you have at least these in place

    volumes:
      - /var/run/dbus/system_bus_socket:/var/run/dbus/system_bus_socket
    privileged: true
    cap_add:
      - NET_ADMIN

    volumes:
      - /var/run/dbus/system_bus_socket:/var/run/dbus/system_bus_socket
    privileged: true
    cap_add:
      - NET_ADMIN

Teppo KurkiOP•3mo ago

i had mapped /var/run/dbus/ and privileged was there already. adding NET_ADMIN did not change anything, same errors. no sensors show time up for today, i'll get back to this

naugehyde•3mo ago

The error occurs when UNKNOWN attempts to read the classMap variable from its constructor which should be set at plug-in load time. Not sure why that might be happening in docker. Not running SK in docker but I'll take a look when I can. In the meantime, @Teppo Kurki can you send the entire log? There may have been an uncaught error earlier

Teppo KurkiOP•3mo ago

figured out the error: I am running docker from master, where the js files are under dist but the server reports being 2.13.5, and your hack of choosing between dist and lib is not firing i would much, much prefer exposing server's functionality in an organized manner, via the API, instead of plugins reaching into dist/lib directly...

naugehyde•3mo ago

an API would be welcome. alternatively you could expose the functionality in the plugin'sapp parameter.

Karl-Erik Gustafsson•3mo ago

I think dist/lib selection might work but as it is tight to server version and official 2.13.5 has lib and now master has dist but still report version as 2.13.5 therefore selection between dist and lib is not activated. Need manually add sudo ln -s dist lib

Teppo KurkiOP•3mo ago

Yep, I just modified the plugin code. Not many people running off master..
