Из чего состоит Pod в Kubernetes?

A Pod in Kubernetes is the smallest deployable unit that can contain one or more containers running on a single host and sharing resources.

Main components of a Pod:

• Containers: one or more containers (usually Docker) that are started together and share resources.
• Shared resources:
  • Network: all containers in a Pod have a shared IP address and ports.
  • Storage: a shared volume accessible to all containers within the Pod.
• Metadata: name, namespace, labels, annotations.
• Specification: describes containers, volumes, restart policies, environment variables, and other settings.

Thus, a Pod provides the co-execution of containers with shared resources and lifecycle management.
