Exposing docker socket to a container (discuss.tchncs.de)

Do you guys expose the docker socket to any of your containers or is that a strict no-no? What are your thoughts behind it if you don't? How do you justify this decision from a security standpoint if you do?

I am still fairly new to docker but I like the idea of something like Watchtower. Even though I am not a fan of auto-updates and I probably wouldn't use that feature I still find it interesting to get a notification if some container needs an update. However, it needs to have access to the docker socket to do its work and I read a lot about that and that this is a bad idea which can result in root access on your host filesystem from within a container.

There are probably other containers as well especially in this whole monitoring and maintenance category, that need that privilege, so I wanted to ask how other people handle this situation.

Cheers!

I just follow the software release pages with RSS.

That is actually a pretty good idea. I wanted to try out FreshRSS anyways, so this might be one more reason to do that. Thanks!
