pip and private repositories - pip

Question

I'm deploying a python application and I'm trying to create a pipeline with Drone.io
In my main application, I have multiple dependencies that are located in private Github repositories requirements.txt:
git+ssh://git#hostname_A/org/repo_A.git
git+ssh://git#hostname_B/org/repo_B.git
For each repository, I have a Github Deploy Key.
So my .drone.yml contains the multiple deploy keys store in drone secrets.
Inside my container, I'm copying a .ssh/config file:
Host hostname_A
HostName github.com
User git
IdentityFile /root/.ssh/repo_A_rsa
Host hostname_B
HostName github.com
User git
IdentityFile /root/.ssh/repo_B_rsa
The issue is that the repository/package repo_B also has a dependency with the private repository repo_A.
And I don't know how to link this private repository, I have tried to add install_requires and dependency_links inside the setup.py of repo_B:
setuptools.setup(
name="repo_B",
install_requires=[
"repo_A_alias # git+ssh://git#hostname_A/org/repo_A.git"
],
)
But I still get the error:
collecting repo_B # git+ssh://git#github.com/org/repo_B.git
Cloning ssh://****#github.com/org/repo_B.git to /tmp/pip-install-naymvvlo/repo_B_67066986e78c4124b8cc99242aeaa673
ERROR: Command errored out with exit status 128: git clone -q 'ssh://****#github.com/org/repo_B.git' /tmp/pip-install-naymvvlo/repo_B_67066986e78c4124b8cc99242aeaa673 Check the logs for full command output.
Or is there a way to access the log file?
