Here are some Kubernetes interview questions and answers to give you an idea of what to expect:
The five types of controller managers are endpoints, service accounts, node, namespace, replication, and token controller manager.
Namespaces divide cluster resources between users, provide a scope of resources, and help the environment where multiple users spread teams or projects.
Daemon sets refer to a set of pods that runs on a host and are used for host layers attributes like simple or monitoring network. The Kubernetes controller manager refers to a daemon that helps with garbage collection, namespace creation, and core control loops. It allows multiple processes to run on the master node.
A Heapster in Kubernetes refers to a metrics collection and performance monitoring system for data the Kublet collects.
Kube-scheduler works as the default scheduler for Kubernetes. It works by assigning nodes to newly created pods.
