The feedback loops behind Kubernetes

Kubernetes operator is a closed feedback loop that ensures desired state for running workloads, similar to a thermostat's control. Operators automate manual tasks in managing databases like Postgres, improving efficiency by comparing and converging states. The same loop structure in a Bash script can be simplified and made scalable with Kubernetes components like kubelet, scheduler, CSI, and Services, creating a production control plane without the need for manual upkeep.
