This might not be totally necessary but I’m wondering if I can limit how much physical memory the Discourse Docker container can utilize using LXC `cgroups`. I’m noticing a gradual memory leak on my server and am not 100% sure where it is at this point:
Pinning down the leak might be a bit easier if I can certifiably know that the Docker container is hard-limited by the kernel.
As a side note, the server is not currently live and has absolutely no traffic.

Its a docker feature and supported by docker, I see no reason you could not set up your server to limit memory a container is allowed to consume.

Sweet! I figured as much but thought that I’d ask anyway. Thanks @sam 🙂
