Question 23

difference between StatefulSet vs. DaemonSet vs. Deployment

Answer 23

StatefulSets run one or more pods with a persistent ID and persistent volumes, which is suitable for running stateful applications.

DaemonSets run one or more pods across the entire cluster or a certain set of nodes. This can be used to run administrative workloads such as logging and monitoring components.

Deployments run one or more pods, allowing you to define how many replicas of the pods need to run, on which types of nodes, and which deployment strategy should be used (for example, a Rolling deployment which replaces pods with a new version one by one, to prevent downtime).
