Caddyfile: permission denied

[ShockedCoder]

It cannot read the Caddyfile even though its permissions are 0644 and it still can't read it even when the perms are 0777.
I've tried everything that I could think of, but I can't find any other instance of this happening.
And I've tried it with the default docker-compose.yml and that also didn't work.

Some more info in-case it's needed:

docker-compose.yml:

version: '3.3'
networks:
  caddy:
services:
  caddy:
    image: caddy:latest
    restart: unless-stopped
    container_name: caddy
    ports:
      - 80:80
      - 443:443
    volumes:
      - ./Caddyfile:/etc/caddy/Caddyfile
      - ./site:/srv
      - ./caddy_data:/data
      - ./caddy_config:/config
    networks:
      - caddy
volumes:
  caddy_data:
    external: true
  caddy_config:

I am experiencing the same issue. So far I have found this thread, where the problem seemed to be incorrect file permissions.

My setup:

• Fedora CoreOS
• Raspberry Pi 4
• Image e4fd3ed314bb.

What I have tried:

• Running it on my local machine, which does not give the error
• Setting permissions of the Caddyfile to 777
• Using user 1000 as owner of the Caddyfile
• Using root as the owner of the Caddyfile
• Mounting an entire folder to /etc/caddy with a Caddyfile

I am not sure where to go with debugging atm, if you need more specs or need me to try something let me know!

After some digging around I found this issue, which, although being version 1.4.4 rather than the 4.2.0 currently, seemed to be the case for me. Following the advice there solved it! @ShockedCoder does this solve it for you too?

Edit:
Just for people looking for a tldr:
You are maybe using SELinux, which comes with stricter permissions, mounting the volume with dir:dir:Z should solve it. You can also mount the folder with dir:dir:z to mark the folder as being shared with other containers too.

SELinux, the fucking bane of my existence.

And yes, it started working now, thank you for your help. Thank you very much.
