How does Docker image tagging work and what is the significance of the ‘latest’ tag?

Key points

  • Tags in Docker are mutable labels pointing to specific image digests
  • 'Latest' tag does not always point to the most recent image
  • Pinning to specific version tags or digests is safer for production
  • 'Latest' is a conventional default tag, not automatically updated
