Hi Victor, K8s always not works with "swap enabled". Refer to: https://github.com/ku bernetes/kubernetes/issues/53533 As "Angus Lees" mentioned, "Applications should configure limits.memory with the max ram they ever want to use, and requests.memory with their intended working set (including kernel buffers, etc)" I think it needs to assign enough memory for STX critical containers to keep system being stable. Please correct me if wrong. thanks, Bin On Mon, 2019-04-29 at 08:42 -0500, Victor Rodriguez wrote:
Hi Frank
I am in charge of the track of performance and footprint of the STX systems
Due to the fact that this bug was a footprint issue I was wondering if should discuss on the meeting on what stages and part of the STX do you want me to track the memory footprint
Also, I have a question regarding the chance to set up -m to each docker image so we can limit the amount of memory of each one. One of the experiments we did las Friday debugging the issue was that if we set -m and the system has SWAP it will take memory from there and keep running since we in STX do not have swap the containers fails from starvation.
