Not updating ghcr.io images

[bruvv]

Description
When using ghcr.io images watchtower isn't finding any updates for it. For example
image: ghcr.io/linuxserver/plex
https://github.com/linuxserver/docker-plex
Will not be updated by watchtower.

Steps to reproduce the issue:

1. https://github.com/linuxserver/docker-plex use that docker-compose file
2. wait for a new latest update (at the time of write it is: https://github.com/linuxserver/docker-plex/pkgs/container/plex/7446206)
3. see watchtower not finding the new images

Describe the results you received:
Still running an older container

Describe the results you expected:
Updatte the older container

Hi there! 👋🏼 As you're new to this repo, we'd like to suggest that you read our code of conduct as well as our contribution guidelines. Thanks a bunch for opening your first issue! 🙏

[piksel]

Probably due to sticky #923

The watchtower logs should state that it was skipped due to missing config data (if you run it with --debug or WATCHTOWER_DEBUG)

[bruvv]

Thanks for linking it, as everything updates just as it should i do not think that it is related to synology (it even updated docker with DSM7 to a v20).
Anyway I ran it with debug enabled and if finds all the containers (22) but misses the Plex one (number 23). I made sure it is running:
a4225257c900 ghcr.io/linuxserver/plex "/init" 7 weeks ago Up 2 weeks
Which it is, when searching in the log there is nothing mention ghcr nor plex like watchtower isn't finding the container. I even ran it with WATCHTOWER_INCLUDE_STOPPED=true to make sure it gets everything but even that doesn't help.
This is my docker-compose.yml:

version: '3'
services:
  watchtower:
    container_name: watchtower
    hostname: watchtower
    image: containrrr/watchtower
    environment:
      - WATCHTOWER_CLEANUP=true
      - WATCHTOWER_REMOVE_VOLUMES=true
      - WATCHTOWER_INCLUDE_STOPPED=true
      - TZ=Europe/Berlin
      - WATCHTOWER_DEBUG=true
    restart: unless-stopped
    network_mode: bridge
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

    command: --interval 30

Could you include the watchtower startup message ( the first info message after start ) and the summary after a session ( debug level, X scanned X updated etc )?
I presume you don't want to include the full log (which of course would be much better).
There is nothing in watchtower itself that singles out ghcr.io repos, so I don't see why only that one would be ignored...

[bruvv]

I do not mind posting everything it is just a very large log file. Here it is:
https://pastebin.com/0VFFwU6G
And the docker inspect:
https://pastebin.com/EPdHZgHC (mind you this is with debug off, this is how I am normally running it)

I have 27 containers. And as far as I can see there is nothing in the logs that shows the containers is there. But I can tell you it is.
Here is the docker inspect of the plex container: https://pastebin.com/YRV7MZGj
Perhaps the docker-compose that I am running for plex is usefull:

version: "2.1"
services:
  plex:
    image: ghcr.io/linuxserver/plex
    container_name: plex
    network_mode: host
    devices:
        - /dev/dri:/dev/dri
    #privileged: true
    labels:
      com.centurylinklabs.watchtower.enable: "false"
    environment:
        - PUID=1026
        - PGID=100
        - VERSION=latest
        - PLEX_CLAIM=claim-*********
    volumes:
        - /volume1/docker/plex:/config:rw
        - /volume1/downloads/movies:/movies:rw
        - /volume1/downloads/series:/tv:rw    
    restart: unless-stopped

[bruvv]

Any update ?

[piksel]

All the pastebin links are removed. Perhaps use gist? I didn't see that you posted before, sorry.

[bruvv]

I have updated all the pastebin links. Note: they're valid for 14 days.

[simskij]

It's not working because the plex container has the following label:

"com.centurylinklabs.watchtower.enable": "false",

[bruvv]

Omg... that I didn't see that, I have no idea why that is in there!
thanks for spotting that
