Supercolliderjs in Docker

[VictorKolb]

Hello!
I'm trying run Supercolliderjs in Docker but got some error:

I'm not sure from looking at the docker file, but I'm guessing it has to do with user permissions.

Try USER ?

[VictorKolb]

Thanks Chris!
I tried to use USER root.
Now my dockerfile looks like:

FROM ubuntu:18.04

USER root

	apt-get install -y software-properties-common gnupg curl && \
    curl -sL https://deb.nodesource.com/setup_14.x | bash && \

	add-apt-repository -y ppa:supercollider/ppa && \
	add-apt-repository -y multiverse && \
	apt-get update && \
    apt-get install -y nodejs supercollider make && \
    apt-get clean


COPY ./package.json package.json
COPY ./package-lock.json package-lock.json

RUN npm i

COPY ./src src

COPY ./Makefile Makefile

CMD ["make", "start"]

Error isn't resolved. Maybe I misunderstood something?

[VictorKolb]

Ok, I have moved a little forward. Now I get the error about display when sclang is starting:

Ok, my journey is continuing.

Now supercolliderjs isn't connecting to Jack.
I notice, when I start supercollider directly like export QT_QPA_PLATFORM=offscreen &&sclang /etc/radio.sc, I can see something like:

JackDriver: connected  system:capture_1 to SuperCollider:in_1
JackDriver: connected  system:capture_2 to SuperCollider:in_2
JackDriver: connected  SuperCollider:out_1 to darkice:left
JackDriver: connected  SuperCollider:out_2 to darkice:right

But when I try export QT_QPA_PLATFORM=offscreen && node index.js this is info didn't appear

[VictorKolb]

Update:
If I add s.boot to file /root/.config/SuperCollider/startup.scd supercollider trying booting server

booting server 'localhost' on address: 127.0.0.1:57110

And JackDriver start to connect. But port already used by previous server, started with supercoliderjs, and connect is interrupted.

debug  : JackDriver: client name is 'SuperCollider-01' <--- As you can see, name is SuperCollider-01 instead SuperCollider
debug  : SC_AudioDriver: sample rate = 44100.000000, driver's block size = 1024
debug  : JackDriver: connected  system:capture_1 to SuperCollider-01:in_1

debug  : JackDriver: connected  SuperCollider-01:out_1 to darkice:left
        JackDriver: connected  SuperCollider-01:out_2 to darkice:right
debug  : Exception in World_OpenUDP: bind: Address already in use

@crucialfelix do you know a way to give a signal to JackDriver about started scsynth?

[VictorKolb]

Ok, all done.
If add this to my .supercollider.yaml all works!

env:
  SC_JACK_DEFAULT_OUTPUTS: "darkice:left,darkice:right"

I'll create PR to add docker example.

[crucialfelix]

Hi. You've got a working Dockerfile with ... icecast? How is it communicating with the world?

We should get this on hub.docker.com

I haven't had anytime to work with supercollider.js unfortunately (full time job)
