Tag images
Docker
Tagging an image in Docker is important for the following reasons:
  • Version control: Tags help identify different versions of an image.
  • Traceability: Tags allow you to track changes and updates to an image.
    Automation: Tags are used in automated processes, such as deploying new versions.
    Troubleshooting: Tags help pinpoint specific image versions when debugging.
    Managing large-scale projects: Tags organize images in complex projects.
