Deployments

StatefulSets and Deployments are both controllers in Kubernetes that are used to manage the deployment and scaling of pods. StatefulSets are designed to manage stateful applications, such as databases or other distributed systems, that require stable network identities, stable storage, and ordered deployment and scaling. StatefulSets use stable network identities, which means that each pod in the set has a stable, unique hostname that persists across restarts. They also use stable storage, which means that each pod has its own persistent storage that is managed by a persistent volume claim. ...

Pods and nodes are both fundamental concepts in the Kubernetes architecture, but they serve different purposes. A pod is the smallest deployable unit in Kubernetes, representing a single instance of a running process in a cluster. A pod can contain one or more tightly-coupled containers that share the same network namespace and storage volumes. All containers in a pod run on the same node, and they can communicate with each other using local host networking. ...
