Mount --user-data-dir for container

[phit42]

I was trying to follow this suggestion (for my docker container install of sockpupp on a Synology NAS):

Don't burn out your disk!! Mount the path for --user-data-dir as a RAM Disk/tmpfs disk ! This will also help to speed up Chrome

so I mounted a directory /volumeSATA/satashare/.../user-data-dir from an external sata drive (I cannot "ram" it but at least I can move it away from my raid drives),
-v /volumeSATA/satashare/.../user-data-dir:/user-data-dir:rw
and told Chromium to use it (env CHROMIUM_FLAGS --user-data-dir=/user-data-dir ).

It doesn't work though. it doesn't recognize the flag or the directory, what am I missing?

I did it like this (docker-compose) and it seems to be written to:

volumes:
  - type: tmpfs
     target: /tmp/cache
     tmpfs:
       size: 1000000000`

and then my flag would be --user-data-dir=/tmp/cache

volumes:

• type: tmpfs
  target: /tmp/cache
  tmpfs:
  size: 1000000000`

Where do you put this flag in the compose? this is mine

  sockpuppetbrowser:
    container_name: SockPuppetBrowser
    image: dgtlmoon/sockpuppetbrowser:latest
    <<: [*config, *dns, *sec]
    networks:
      eth1:
        ipv4_address: ${sockpuppetbrowser_ip}
    ports:
        - 3000:3000
        - 8080:8080
    volumes:
      - type: tmpfs
        target: /tmp/cache
        tmpfs:
          size: 1000000000`
    environment:
      - SCREEN_WIDTH=1920
      - SCREEN_HEIGHT=1024
      - SCREEN_DEPTH=16
      - MAX_CONCURRENT_CHROME_PROCESSES=10

Thank you @marrrc @lordraiden . This utilises the system's tmp directory to cache the information. tmp on my system is not big enough, thus I wanted to move it to a separate directory (on a mounted volume). Any idea why that wouldn't work?

you were missing a "=" in:
CHROMIUM_FLAGS
