#git tag
Think of a git tag as an alias to a sha1 or to a branch.
The Git Book on tagging says there are two main typs of tags, lightweight and annotated. Lightweight only records commit and tag. Annotated records who, what, when and where. Use annotated, -a.
List all tags:
$ git tag
To tag your current commit:
$ git tag -a <tag_name> -m '<message>'
To tage a previsous commit:
$ git tag -a <tag_name> -m '<message' <sha1>
git push doesn't push the tag names to the repo. To push all tags to the repo:
$ git push origin --tags
Or individual tag:
$ git push origin <tag_name>
Delete tag localy:
$ git tag -d <tag_name>
Push deleted tag changes to repo:
$ git push origin :refs/tags/<tag_name>
