GIT: How do I update my bare repo?

Question

I created a bare repo to publish my repository, but I can't figure out how to update the bare repo with the current state of the main repository.

Answer 1

Add the bare repository as a remote repository, then use git push.

Answer 2

If you want to duplicate all the objects from the main repo, do this inside the main repo:

git push --all <url-of-bare-repo>

Alternatively, do a fetch inside the bare repo:

git fetch --all <url-of-main-repo>

You cannot do a pull, because a pull wants to merge with HEAD, which a bare repo does not have.

You can add these as remotes to save yourself some typing in the future:

git remote add <whatever-name> <url-of-other-repo>

Then you can simply do

git push --all <whatever-name>

or

git fetch --all <whatever-name>

depending on what repo you're in. If <whatever-name> is origin, you can even leave it out altogether.
