Git Submodules with Heroku
Since Heroku doesn't currently support submodules, one other possible way would be to use sub-tree merging.
Basically, sub-tree merging is a Git merging strategy that allows you to merge another git repository into yours, but in a subdirectory of your choosing. There's a tool called git-subtree
, which tries to wrap this process in a way similar to git-submodule(1)
.
Other than the git-merge(1)
man page, there are a few other articles that can help you with this merging strategy:
- github:help on subtree merging
- Pro Git Chapter 6, Section 7: Subtree Merging
- I've also written a post called "Subtree merging and you"
There is another alternative to @Daniel Eisenhardt approach: https://stackoverflow.com/a/29464430/990356
Go to Settings > Personal access tokens and generate a personal access token with repo
scope enabled.
Now you can do git clone https://[email protected]/user-or-org/repo
and in the case of a submodule git submodule add https://[email protected]/user-or-org/repo
Pros:
- very simple approach
- token can be easily revoked
- your real password is safe
Cons:
- if someone has access to the token, he can access your GitHub repos (read and write)
Heroku now supports submodules.

However, this feature does not support submodules that are private.
