Pods are foundational to building and running applications in Kubernetes. They provide the execution environment for containers, encapsulating application components, managing their lifecycle, and facilitating inter-component communication and resource sharing. A Pod encapsulates one or more containers, storage resources, a unique network IP, and options that govern how the container(s) should run. Containers within a …
