Please add a warning regarding the security risks of sharing the docker.sock to this wiki page.

Sharing the docker.sock with Uptime Kuma container means trivial privilege escalation and container escape, affecting security of both other containers as well as the docker host! The read-only flag does not prevent this type of attack at all since the socket is not a regular file on the file system.

I've also commented regarding this issue here:
louislam/uptime-kuma#2061 (comment)

You also mention:

:ro (readonly) is recommended.

This might lead to a false understand of the security implications of sharing the docker.sock file, because as already stated, setting this flag does not really matter in this case as this is not a regular file.

If Uptime Kuma is exposed to the Internet, because of security reasons I advice against sharing the docker.sock with Uptime Kuma, even if it is a nice feature.
