[git] How do you push a tag to a remote repository using Git?

I have cloned a remote Git repository to my laptop, then I wanted to add a tag so I ran

git tag mytag master

When I run git tag on my laptop the tag mytag is shown. I then want to push this to the remote repository so I have this tag on all my clients, so I run git push but I got the message:

Everything up-to-date

And if I go to my desktop and run git pull and then git tag no tags are shown.

I have also tried to do a minor change on a file in the project, then push it to the server. After that I could pull the change from the server to my Desktop computer, but there's still no tag when running git tag on my desktop computer.

How can I push my tag to the remote repository so that all client computers can see it?

To push a single tag:

git push origin <tag_name>

And the following command should push all tags (not recommended):

git push --tags

To push specific, one tag do following git push origin tag_name

You can push the tags like this git push --tags

You can push all local tags by simply git push --tags command.

$ git tag                         # see tag lists
$ git push origin <tag-name>      # push a single tag
$ git push --tags                 # push all local tags 

Tags are not sent to the remote repository by the git push command. We need to explicitly send these tags to the remote server by using the following command:

git push origin <tagname>

We can push all the tags at once by using the below command:

git push origin --tags

To expand on Trevor's answer, you can push a single tag or all of your tags at once.

Push a Single Tag

git push <remote> <tag>

This is a summary of the relevant documentation that explains this (some command options omitted for brevity):

git push [[<repository> [<refspec>…]]

<refspec>...

The format of a <refspec> parameter is…the source ref <src>, followed by a colon :, followed by the destination ref <dst>…

The <dst> tells which ref on the remote side is updated with this push…If :<dst> is omitted, the same ref as <src> will be updated…

tag <tag> means the same as refs/tags/<tag>:refs/tags/<tag>.

Push All of Your Tags at Once

git push --tags <remote>
# Or
git push <remote> --tags

Here is a summary of the relevant documentation (some command options omitted for brevity):

git push [--all | --mirror | --tags] [<repository> [<refspec>…]]

--tags

All refs under refs/tags are pushed, in addition to refspecs explicitly listed on the command line.

How can I push my tag to the remote repository so that all client computers can see it?

Run this to push mytag to your git origin (eg: GitHub or GitLab)

git push origin refs/tags/mytag

It's better to use the full "refspec" as shown above (literally refs/tags/mytag) just in-case mytag is actually v1.0.0 and is ambiguous (eg: because there's a branch also named v1.0.0).

I am using git push <remote-name> tag <tag-name> to ensure that I am pushing a tag. I use it like: git push origin tag v1.0.1. This pattern is based upon the documentation (man git-push):

OPTIONS
   ...
   <refspec>...
       ...
       tag <tag> means the same as refs/tags/<tag>:refs/tags/<tag>.
