Unable to deploy when composer.json references another repo

[edgreenberg]

Bug Report

• At what date and time did you most recently experience the problem? 2021-11-23@13:00 EST

• Where did you experience the problem? E.g. Azure Web Apps, Azure Functions, Azure Container Registry, or offline use. Azure Web Apps

• If your repo is publicly available please share its URL: it's a github enterprise repo

• What happened? After the repo is pulled, Oryx tries to run composer install. The composer.json contains a reference to a package in one of our git repositories. Oryx (I believe) doesn't look at /root/.ssh/config to resolve the hostname 'gitfilestore' If it did, I'm not sure which private key it would present. I can't add the private key I got from kudu to both the main repo and this small package repo.

• What did you expect or want to happen? I wanted it to execute the command:

git clone --mirror 'git@gitfilestore:HappySoftware/FileStore' '/home/.cache/composer/vcs/git-gitfilestore-HappySoftware-FileStore/'

so that the hostname is resolved in the the config directory and the specified private key in the /root/.ssh directories is used.

• How can we reproduce it? You need a repo containing a composer style package and to reference it in the composer.json

• Do you have log output? Please include between the backticks:

This is what my section of composer.json looks like:

    "repositories": [
        {
            "type": "git",
            "url": "git@gitfilestore:HappySoftware/FileStore"
        }
    ],

And this is what the section of the config file is:

Host gitfilestore
    Hostname github.happysoftware.com
    IdentityFile /home/git/.ssh/id_rsa_filestore
    IdentitiesOnly yes
