$ git tag -a v2.0.0 -m "second stable release" You can also pass the tag message with the git tag command using “-m” flag. This will open the configured git editor for tag messages. To create annotated tag pass the “-a” flag. To create a lightweight tag run the “git tag” command followed by the version number. LIGHTWEIGHT TAGS – This creates a pointer to a specific commit but does not store information like when and who created the tag.ĪNNOTATED TAGS – This creates a pointer to a specific commit and stores information like when and who created the tag with the tag message. Git supports two types of tags lightweight and annotated tags. $ git log -oneline -allĢ06f49c (HEAD -> master) TAGS - second commit for tag demoĭ065fdd TAGS - First commit for tag demo Create Lightweight & Annotated Tags In Git To check the logs for your repository run the following command. $ git commit -m "TAGS - second commit for tag demo" $ echo "second commit for tags" > ftag2.txt $ git commit -m "TAGS - First commit for tag demo" $ echo "First commit for tags" > ftag1.txt Run the following commands which will create a directory called tags and create two commits. If you wish to follow along, this section will help you in creating a sample repository. Tags are git features and releases are github features where you will create release notes, and generate binaries through CI/CD pipeline like github actions, etc. Tags and releases are related to one another. Using semantic versioning scheme tags are created in the repository. Click on tags and you will see a complete history of tags associated with this project. You will see a section called tags in the repository. To make more sense of how the tag works with a real project, I picked the vagrant project hosted on github. A real use case would be, you may work on bugfix/branch and after a couple of commits, you will be merging the bugfix with the main or release branch where you can create tags and release the next patch version for the product. Tags are nothing but a label for a particular commit in a branch. In git, these version numberings are created with tags. When you release your product you will name the release with a version number and these version number follows the semantic versioning scheme. There will be a point when your product is ready to be released for public use. If you use an invalid tag name, git will reject the push operation.Let’s say your company is working on an open-source project where your team writes code, uses git to version the project, and creates multiple commits. For example, tag names cannot contain spaces or special characters. Git imposes certain restrictions on tag names. Tag names may not allow some special characters If you encounter errors when attempting to push tags make sure you have the necessary permissions or consult with the repository administrator. Watch for permissions required to push tagsĭepending on the configuration of the remote repository you may need appropriate permissions to push tags. In this case you need to resolve the merge conflicts before you can successfully push the tag. If you push a tag that points to a commit that conflicts with changes in the remote repository git will reject the push operation. Pushing a tag with a commit that has merge conflicts If you need to update a tag, you should delete the existing tag and create a new one with the desired changes. Attempting to push a tag with the same name as an existing tag will result in an error. Git tags are meant to be immutable and serve as stable references to a specific point in the repository's history. Common Gotchas Pushing a tag with the same name as an existing tag This will ensure that the -follow-tags option is enabled with every git push command which will push the commits and associated annotated tags. $ git config -global push.followTags true Prior to git version 1.8.3, to push both the commits and the tags at the same time, you had to call the git push command twice using the & changing operator:
