Pihole on docker won't show the web UI

Help

Yes. Here are the virtual hosts I've tried

  1. redactedhost.local
  2. redactedhost
  3. pi.hole

Every one of the tests was run with the following command: docker stop pihole && rm -rf data/pihole/ && docker-compose up -d

The docker configuration is

  pihole:
    container_name: pihole
    image: pihole/pihole:v5.7-stretch
    ports:
      - "9053:53/tcp"
      - "9053:53/udp"
      - "9080:80/tcp"
    environment:
      - VIRTUAL_HOST=pi.hole
    env_file:
      - ./.env.compose
      - ./secrets/pihole/env
    volumes:
      - ./data/pihole/pihole:/etc/pihole
      - ./data/pihole/dnsmasq:/etc/dnsmasq.d
    restart: unless-stopped

And the env files have the following keys:

  • WEBPASSWORD=redacted
  • ADMIN_EMAIL=redacted@redacted.redacted
  • PUID=500
  • PGID=1000
  • TZ=Asia/Kolkata
  • UMASK_SET=022
    (other containers in my compose file use these variables. Next up, I'll try removing them to see if it helps). I doubt it does because it was working last night with the same setup.

Absolutely. Plus this image worked last night. It's definitely something wrong with the host machine but I can't figure out what since I've changed the image and also deleted ./data/pihole to reset it's state. :frowning:

Any idea what this means from the docker logs?

$ docker logs -f pihole
[...]
[cont-init.d] 20-start.sh: executing...
 ::: Starting docker specific checks & setup for docker pihole/pihole
Failed to set capabilities on file `/usr/bin/pihole-FTL' (Operation not supported)
The value of the capability argument is not permitted for a file. Or the file is not a regular (non-symlink) file

I noticed a very similar issue when mounting /usr/bin on a NFS. I'm running everything inside the docker container and nothing is mounted to /usr/bin :disappointed:

Update: Forgot to link the "very similar issue"
