I have a GitLab project that utilises GitLab CI. The project also uses submodules, both the project and it's submodules are under the same GitLab account.
Here is my .gitmodules file
[submodule "proto_contracts"]
path = proto_contracts
url = https://gitlab.com/areller/proto_contracts.git
I also have this piece in the .gitlab-ci.yml file
variables:
GIT_SUBMODULE_STRATEGY: recursive
However, when i run the CI I get this error
fatal: could not read Username for 'https://gitlab.com': No such device or address
Both the project and the submodules are in a private repository so you would expect to be prompted for authentication, but as I've mentioned, the project and the submodule are under the same account and one of the runner's jobs is to clone the original repository
So it's odd that it's unable to reach the submodule Is there a way around it?

Pulling with submodules. Once you have set up the submodules you can update the repository with fetch/pull like you would normally do. To pull everything including the submodules, use the --recurse-submodules and the --remote parameter in the git pull command .
all tiers. Use Git submodules to keep a Git repository as a subdirectory of another Git repository. You can clone another repository into your project and keep your commits separate.
This is because of some major drawbacks around git submodules, such as being locked to a specific version of the outer repo, the lacking of effective merge management, and the general notion that the Git repository itself doesn't really know it's now a multi-module repository.
Git submodules may look powerful or cool upfront, but for all the reasons above it is a bad idea to share code using submodules, especially when the code changes frequently. It will be much worse when you have more and more developers working on the same repos.
You must use relative URLs for submodules. Update your .gitmodules as follow:
[submodule "proto_contracts"]
path = proto_contracts
url = ../../areller/proto_contracts.git
