Hi everyone!
I run a few low-resource-usage containers on a home server that also has things that run directly on the metal. I'm starting to run a simple Docker container that just lets me run the Whisper speech-to-text engine. That container basically uses all of my CPU power for several hours, which is fine, but I want to make sure it's not starving other processes of CPU time.
In a non-Docker setup, I'd just nice the program, and that'd be it, but that doesn't seem to work in this context. I've found this Stack Overflow post that recommends using the --cpu-shares flag with docker run, but I haven't been able to find out if that allows you to deprioritize the container relative to everything else using the CPU (such as non-containerized tasks) or just relative to other containers.
Any help would be appreciated!
If you want to keep it containerized, an LXC would let you limit CPU usage vs. host processes like you're wanting.
