What is PodPods are the smallest deployable units that can be used to create and manage kubernetes calculations. A pod represents a process that runs in a cluster.Pods are like pea pods, which consist of one or more containers (such as Docker containers) that share container storage, network, and container run configuration items. The containers in the
the same as restarting the pod. The pod only provides the container's operating environment and keeps the container running, and restarting the container does not cause the pod to restart.(2) pod does not heal. If the pod is running node failure, or if the scheduler itself

Pod is the most basic deployment dispatch unit in Kubernetes, and it can contain container, which logically represents an instance of a certain application. For example, a Web site application is built from the front end, back end, and database, and these three components will run in their respective containers, so we can cre

Kubernetes cluster has been set up, has been running very stable. Previous concerns have focused more on installation, configuration, and component debugging, and some of the minutiae has been overlooked. The settings for the time zone in the pod are one of them.
