Git Submodules: Is it possible to have more than one URL for each?

I was wondering if it is possible to have more than one URL for each git submodule. It would be interested to have more than one source of it if one of them is down or someone is behind a proxy that blocks one of them.

Have you ever had this problem? How would you solve it?

From the submodule directory, use these commands to add additional remotes. If you omit the first command, it will replace your original remote URL, so you need to run both.

git remote set-url --add --push [remote] [original repo URL]
git remote set-url --add --push [remote] [second repo URL]

As far as I know, one submodule has only one url, which is referenced in:

  • .gitmodules
     $ cat .gitmodules
     [submodule "a"]
             path = a
             url = /home/moses/subtut/public/a/.git
     [submodule "b"]
             path = b
             url = /home/moses/subtut/public/b/.git
  • and in the config of the .git directory of the submodule

Meaning if that url is down, it may have to be changed in those two locations, but I have not tested that process.

Good comments from Gattster

git submodule sync.

According to the docs:

Synchronizes submodules' remote URL configuration setting to the value specified in .gitmodules.
This is useful when submodule URLs change upstream and you need to update your local repositories accordingly.

  • "git submodule sync" synchronizes all submodules
  • while "git submodule sync -- A" synchronizes submodule "A" only.

That being said, modifying .gitmodule might be better done in isolation (i.e. in a branch) until those new url can be validated/published.

I don't believe it is possible. It should be possible to manually do this by checking out your project, initializing your submodules, and then cd into a submodule directory and update the git remote origin to the new repository URL.
