📝 Describe your problem

I'd like to run Uptime Kuma with a different user in Docker, because currently it's running as root.
How can I define it here?

Example:

    environment:
      - USER_ID=1006
      - GROUP_ID=996

Thanks!

See https://github.com/louislam/uptime-kuma/wiki/Environment-Variables#docker-specific-environment-variables
You could use the standard PUID/PGID. I have not tested if they work.

v2 will come with full support of running as another user via the -rootless tags. See #4052 for further context.
See #4171 for what bugfixes still need to happen until a first beta can be issued.

Hmm, that's strange... The document says that the default PUID and GUID are 1000, but when I set these values:

    environment:
      - PUID=1000
      - PGID=1000

in a docker compose, the Uptime Kuma cannot check the container status. Any idea why?

[CommanderStorm]

cannot check the container status

How have you mounted the docker socket?
What are the permissions of said socket?
Can the chosen PUID/PGID access said socket?

[Feriman22]

You can find my docker compose below. I have added it as read only, due to the checking doesn't require a write permission.

srw-rw---- 1 root docker 0 Jan 14 12:14 /var/run/docker.sock

The user with PIUD 1000 is part of the docker group, so it has an access to it.

version: '3.8'

  uptime-kuma:
