Git tags

Listing Your Tags

git tag will list all the tags in the repo
git tag -l 'v1.8.5*' will use the wild card to list only the matches

Creating Tags

Types

lightweight tag: is very much like a branch that doesn’t change – it’s just a pointer to a specific commit.
annotated tag: are stored as full objects in the Git database. (recommended)

Lightweight tags

To create a lightweight tag, don’t supply the -a, -s, or -m option.
This is basically the commit checksum stored in a file – no other information is kept.

Annotated tags

They’re checksummed; contain the tagger name, email, and date; have a tagging message; and can be signed and verified with GNU Privacy Guard (GPG).

You need to use -a flag eg. git tag -a v1.4 -m 'my version 1.4'

You can see the tag data along with the commit that was tagged by using the git show command:
eg. git show v1.4

That shows:

the tagger information
the date the commit was tagged
the annotation message before showing the commit information.

Tagging Later

Just add the commit hash at the end.

git tag -a v1.2 9fceb02

git push origin --tags pushes all tags
git push origin v1.5 pushes a specific tag
