JAVA_OPTS doesn't seem to be working

[RulerOf]

My setup

• Host OS: Oracle Linux 7

• Log output (probably unhelpful).
  • Obtained with grep -v liquibase ./airsonic/config/airsonic.log to filter out noise.

• No volume mount symlinks

• docker-compose .env:

DOMAIN=mydomain.com
TZ=America/New_York
PGID=1000

• portion of docker-compose.yml:

  airsonic:
    depends_on:
      - traefik
      - plex
    image: linuxserver/airsonic:latest
    container_name: airsonic
    hostname: airsonic
    restart: unless-stopped
    volumes:
      - ./airsonic/config:/config
      - /storage/media/music:/music
      - ./airsonic/playlists:/playlists
      - /storage/media/podcasts:/podcasts
    environment:
      - PGID
      - PUID=1006
      - TZ
      - JAVA_OPTS="-Dserver.use-forward-headers=true"
    labels:
      traefik.enable: "true"
      traefik.port: "4040"
      traefik.frontend.rule: "Host:airsonic.${DOMAIN}"
      com.centurylinklabs.watchtower.enable: "true"

Details

It doesn't seem that JAVA_OPTS is being honored in this container, and looking at the run file doesn't show it referenced in there anywhere.

After bringing up the container on my system, I check my running processes and anything in the JAVA_OPTS environment variable doesn't get added to the java process's command line:

[root@drew-metal content-engine]# docker-compose start airsonic
Starting airsonic ... done
[root@drew-metal content-engine]# ps aux | grep airsonic

I had to remove the quotes from the JAVA_OPTS to make the container work after applying #9

Looks like we forgot to add JAVA_OPTS to the run command. Thanks for notifying us. I'll do an inhouse PR to make the variable available in another way. Something to do with linting I think.

That was quick. Thanks, @tobbenb!
