What is a Docker Registry, and how is it different from Docker Hub?
A registry is any server implementing the Docker Registry HTTP API v2 for storing and distributing images by name and digest. Docker Hub is Docker Inc.'s public hosted registry and the default one the CLI pulls from. Private alternatives include AWS ECR, GitHub Container Registry (GHCR), Google Artifact Registry, and self-hosted options like Harbor or Nexus.
