We are trying to run a small-scale AKS cluster with minimal resources. We're running into an issue where our limits are far exceeding our allocation on the CPU. After reviewing our deployments we noticed the CoreDNS deployment has a CPU limit of 3 and it's running two replicas (6 total). Changing the YAML file to a different limit changes the limit temporarily, but then reverts back only after a few mins.
If anyone could point us to some documentation or help us it would be greatly appreciated.
