OMV7 Docker Compose Cups don't work ...

mirada · Apr 15th 2025

I now want to install a print server on my OMV7 and have decided on Docker/Compose. Under OMV5, I had CUPS installed natively, which worked well. I've tried various Docker images, but none of them work for CUPS... Most of them require a username/password, but no combination I know of has been accepted.

Than I found my currently following image:

Code

# version: '3.5'
services:
  cups:
    image: chuckcharlie/cups-avahi-airprint:latest
    container_name: cups
    network_mode: host
    volumes:
      - /srv/dev-disk-by-uuid-fb1e45f4-ea1c-4de9-b916-189ef60fe594/Docker/_appdata/chuckcharlie/services:/services
      - /srv/dev-disk-by-uuid-fb1e45f4-ea1c-4de9-b916-189ef60fe594/Docker/_appdata/chuckcharlie/config:/config
    ports:
      - 631:631
    environment:
       CUPSADMIN: "print" 
       CUPSPASSWORD: "print"
    restart: unless-stopped

(From here)

The page 192.xxx.x.xx:631/ opens (OpenPrinting CUPS 2.4.11), but after clicking on 'Administration (Verwaltung)' and entering the username/password (print/print), only 'Internal Server Error' appears in the Window.

Example click on 'Klassen' :

Unable to get class list

Bad file descriptor

Maybe I have an error in the file or user permissions (appuser) or an incorrect entry in the shared folders...

A ports statement is not need and ignored when using host networking.

Try changing the environment variables by removing one leading space like this:

Code

environment:
  CUPSADMIN: "print" 
  CUPSPASSWORD: "print"

Entering the password seems to work. If I enter the wrong one, the prompt keeps coming up. It only disappears when I type print/print. But then the error message appears (full black window, white letters, upper left corner) :

Internal Server Error

I've changed things quite often. And yes, I've read the references to 'Docker in OMV 7' and '(Docker) Compose Plugin For OMV7' on wiki.omv-extras.org (and some other sites in the WWW).

Code

# version: '3.5'
services:
  cups:
    image: chuckcharlie/cups-avahi-airprint:latest
    container_name: cups
    network_mode: host
    volumes:
      - ${appdata}/chuckcharlie/services:/services
      - ${appdata}/chuckcharlie/config:/config
    environment:
       CUPSADMIN: "print" 
       CUPSPASSWORD: "print"
    restart: unless-stopped

Result of "check" :

resulted in the error message:

then go back to previous configuration

but the Result :

see 'cups login.jpg' below

try to log in with

print : print

root : my.root.pw

my.user : my.user.pw

but all are not accepted

the password request keeps coming up

maybe this helps:

Code

insgesamt 48

I'm hoping for some help, because this printer server is really getting on my nerves...
