In git, how do I sync my tags against a remote server?
GitGit TagGit Problem Overview
Is there a way to keep my local git tags in lockstep with a remote's tags? That is -- not only get new tags when created (as usual, when fetch
-ing/pull
-ing), but also prune tags no longer on a remote and also delete existing tags when someone else git push -f
's a tag.
I know I can git fetch remotename
followed by git remote prune remotename
to achieve similar behaviour for branches.

Solution 1 - Git
> ...also prune tags no longer on a remote
git fetch
gets with Git 2.17 (Q2 2018) an handy short-hand for getting
rid of stale tags that are locally held.
See commit 6317972, commit 97716d2, commit e249ce0, commit 627a129, commit d0e0747, commit 2c72ed7, commit e1790f9, commit 59caf52, commit 82f34e0, commit 6fb23f5, commit ca3065e, commit bf16ab7, commit eca142d, commit 750d0da, commit 0711883, commit ce3ab21, commit aa59e0e (09 Feb 2018) by Ævar Arnfjörð Bjarmason (avar
).

> ## fetch: add a --prune-tags
option and fetch.pruneTags
config
> Add a --prune-tags
option to git-fetch
, along with fetch.pruneTags
config option and a -P
shorthand (-p
is --prune
).
This allows for doing any of:
>
> git fetch -p -P
> git fetch --prune --prune-tags
> git fetch -p -P origin
> git fetch --prune --prune-tags origin
>
> Or simply:
>
> git config fetch.prune true &&
> git config fetch.pruneTags true &&
> git fetch
>
> Instead of the much more verbose:
>
> git fetch --prune origin 'refs/tags/:refs/tags/' '+refs/heads/:refs/remotes/origin/'
>
> Before this feature it was painful to support the use-case of pulling
from a repo which is having both its branches and tags deleted
regularly, and have our local references to reflect upstream.
>
> At work we create deployment tags in the repo for each rollout, and
there's lots of those, so they're archived within weeks for
performance reasons.
>
> Without this change it's hard to centrally configure such repos in
/etc/gitconfig
(on servers that are only used for working with
them). You need to set fetch.prune=true
globally, and then for each
repo:
>
> git -C {} config --replace-all remote.origin.fetch "refs/tags/:refs/tags/" "^+*refs/tags/*:refs/tags/*$"
>
> Now I can simply set fetch.pruneTags=true
in /etc/gitconfig
as well,
and users running "git pull
" will automatically get the pruning
semantics I want.
Update Apr. 2021, Git for Windows 2.30.1 and GitHub Desktop 2.8
It works if you have set prune
and pruneTags
options:
cd C:\path\to\local\repo
git config fetch.prune true
git config fetch.pruneTags true
Then click on Fetch origin in GitHub Deskop: the logs will show:
2021-04-28T20:25:21.244Z - info: [ui] Executing fetch:
git -c credential.helper= -c protocol.version=2 fetch --progress --prune origin (took 2.986s)
... and any local tag not present in the remote will be gone!
Solution 2 - Git
The following worked for me:
git fetch --prune --tags
Solution 3 - Git
A bit of research has shown that git has no way to tell the difference between local or foreign tags (all tags go to .git/refs/tags/). Therefore, it is not possible to determine the difference between locally created tags and prune-able remote tags. The options, are then reduced to: having an ever growing set of tags, or only the tags that are on the server.
git push --tags origin && \
git tag | xargs -n1 git tag -d && \
git fetch --tags
Drop the first line for the latter behaviour, and could be potentially git alias'd for frequent usage.
An alternative would be to create a branch (as they can be identified as local/remote) at a tag point and are never write to it again. Then using remotename/branchname as a tag to checkout would keep tags in sync (in addition to git fetch
and git remote prune remotename
).
Either way is a hack, and the "right" answer is to stop changing tags all the time.
Solution 4 - Git
Another solution which actually works for me:
git tag -l | xargs git tag -d && git fetch -t
Solution 5 - Git
use these command to sync tags(delete all local then fetch all remote)
git tag -d $(git tag) # delete all local tags
git fetch --all # fetch all remote to local
Solution 6 - Git
git push --tags will push your local tags up to the server. By default, git fetch (the first half of git pull or git pull --rebase) will pull tags, but you can specify -t or --tags to pull all of them.
I'm not sure how to prune remotely deleted tags, but the fetch should pull down any force-updated tags.
Solution 7 - Git
disclaimer this uses git internals (some may argue that the filesystem is a git interface, but that's for another day :D)
# Blow away all local tags, this will remove any that are tagged locally
# but are not on the remote
rm .git/refs/tags/*
# Download all the tags from the remote
git fetch --tags
Solution 8 - Git
Here's an alternative solution:
git fetch -p +refs/tags/*:refs/tags/*
From the git fetch doc:
