标签

1. 轻量标签
   一个特定提交的引用

$ git tag v0.1

$ git tag
v0.1

2. 附注标签
   附注标签是存储在 Git 数据库中的一个完整对象。 它们是可以被校验的

$ git tag -a v0.2 -m 'tag0.2'

$ git tag
v0.1
v0.2

3. 补标签

$ git log --stat

4. 共享标签
   默认情况git push 命令不会推送标签到git远程仓库。可以使用git push <remote> [tagname] 显式推送

$ git push git-test v0.1
Total 0 (delta 0), reused 0 (delta 0)
To https://github.com/dongwudi/gittest.git
 * [new tag]         v0.1 -> v0.1

也可以使用git push <remote> --tags一次性推送所有不在远程仓库上的标签。

$ git push git-test --tags
Enumerating objects: 3, done.
Counting objects: 100% (3/3), done.
Delta compression using up to 8 threads
Compressing objects: 100% (3/3), done.
Writing objects: 100% (3/3), 313 bytes | 156.00 KiB/s, done.
Total 3 (delta 1), reused 0 (delta 0)
remote: Resolving deltas: 100% (1/1), done.
To https://github.com/dongwudi/gittest.git
 * [new tag]         v0.2 -> v0.2
 * [new tag]         v0.3 -> v0.3
 * [new tag]         v0.4 -> v0.4

5.删除标签

$ git tag -d v0.1
Deleted tag 'v0.1' (was 8727432)

上述命令并不会从远程仓库中移除这个标签，你必须使用 git push <remote> :refs/tags/<tagname> 来更新你的远程仓库

$ git push git-test :refs/tags/v0.1
To https://github.com/dongwudi/gittest.git
 - [deleted]         v0.1
