Containers are the basic building blocks for running individual applications, pods provide the orchestration-friendly abstraction that allows Kubernetes to manage, scale, and heal applications effectively.

Why Pods Exist

  • Abstraction Layer: Pods abstract container management, enabling Kubernetes to orchestrate and manage workloads.
  • Multi-Container Design: Some applications benefit from having multiple containers work together within the same pod, such as:A main application and a helper container.A sidecar for logging, monitoring, or caching.

Example Use Case

  • A web server and a file fetcher (sidecar) container might run together in a pod. The web server serves requests, and the file fetcher synchronizes data from an external source. Both share the same network and storage.
