Hey everyone, I'm pretty new to Docker and I'm trying to understand the security implications of my setup. My Nginx proxy configuration includes '/var/run/docker.sock:/tmp/docker.sock:ro' in the volumes section. I've heard that mounting it as read-only can help reduce security risks, but I'm still feeling a little uncertain about it. Is this setup safe enough for a production environment, or should I be more concerned?

Mounting the Docker socket as read-only doesn’t really provide the security you might think it does. Even with that ‘:ro’ flag, you can still send both read and write API requests. If you're looking to secure your setup, consider using a socket proxy that helps filter which API calls are allowed or blocked.
