What happens if Kubernetes master node fails?
Whenever master node under kubernetes fails, the cluster still remains in an operational mode. It doesn’t affect pod creation or service member changes. If worker node fails, master stops receiving updates from worker node.
How many pods does node Kubernetes have?
