I am running some programs inside containers within Kubernetes and use Prometheus for plotting some metrics like CPU utilization over a specific period of time, network I/O and so on. Basically the programs are encrypting some images I uploaded into a shared folder and for some reasons which I am not aware of, when the programs stops running inside the containers, their resource consumptions do not come back to the initial state (e.g., 0 CPU utilization) before encryption. Not sure if the resources are not released by Kubernetes or whatsoever. Any help ?
