Resolves #1024
What is the feature
The feature is to allow the configuration of dynamic tags for Docker images built through Git, such as using a commit ID prefix.
Why we need the feature
This feature is needed to automate the tagging process of Docker images, ensuring that each build is uniquely identifiable and traceable back to a specific commit. This helps in maintaining a clear version history and simplifies the process of identifying the source of a particular image.
How to implement and why
Identify the Build Process: Locate the script or configuration file responsible for building Docker images. This is likely within the
scriptsdirectory or a CI/CD configuration file.Extract Commit ID: Use Git commands to extract the current commit ID during the build process. This can be done using
git rev-parse --short HEADto get a short version of the commit ID.Modify Tagging Logic: Update the tagging logic in the build script to include the commit ID as a prefix or suffix. For example, modify the Docker build command to use
docker build -t myimage:${COMMIT_ID}.Configuration Option: Allow this behavior to be configurable. This can be achieved by introducing an environment variable or a configuration file entry that enables or disables dynamic tagging.
Update Documentation: Ensure that the README or any relevant documentation is updated to reflect this new feature, including instructions on how to enable and configure it.
About backward compatibility
Backward compatibility should be maintained by making the dynamic tagging feature optional. By default, the existing static tagging method should remain unchanged unless the user explicitly opts into the new dynamic tagging feature. This ensures that existing workflows are not disrupted.
