git tag

git tag: tag a Git commit

The git tag command is used to create tags in your Git repository. Tags are like labels or milestones that you can use to mark important points in your project's history, such as release versions (v1.0.0, v2.0.0). They are similar to branches but cannot be moved once created - they are fixed points.

Creating tags does not change the repository itself (the commits that are tagged remain identical). Instead, it helps to provide more context and milestones within the project's development, making it easier for teams and contributors to track progress, revert to stable versions, and understand the history of changes. They are also helpful for build or release automation, as tools can use tags to identify which version to package or deploy.

Tags in Git come in two types:

• Lightweight tags are simple pointers to specific commits. These tags are mainly used for referencing commits with human-readable names.

• Annotated tags are stored as full objects in the Git database, including the tagger name, email, date, and a tagging message. They can be GPG signed and verified for security and trust. These tags are recommended for marking official release versions because they contain additional information.

Examples

git tag -a v1.0.0 -m "Release version 1.0.0"

git tag v1.0.1

git tag

git tag -d v1.0.1

git push origin --tags

git push origin v1.0.0
