In gke environment I have a cluster with three pods on which a docker image with ubuntu and wordpress is scaled. In the infrastructure, the CPU usage is regular while the memory constantly increases until it becomes saturated in a week, around 10gb. I have 64 gigabytes of ram available and I tuned the os (cache management, logrotation management, various php.ini checks) and verified anomalous consumption by the application, but there seems to be no remedy. I don’t know where to turn my head anymore. Can you help me? Thank you
