devcontainer-feature.json with github ssh access

[Desmond Kirrane (dkirrane)]

I'm creating a custom devcontainer feature using https://github.com/devcontainers/feature-starter.

My custom devcontainer feature needs GitHub.com access.

Is there a way for devcontainer test to reuse SSH keys?
devcontainer features test --features featureX --skip-scenarios

My attempt but it seems the devcontainer features test cli ignores the mount and containerEnv in the scenarios.json

{
    "test": {
        "image": "mcr.microsoft.com/devcontainers/base:ubuntu",

        "features": {
            "chezmoi": {
                "github_username": "dkirrane"
            }
        },

        "mounts": [
           // SSH Agent forwarding by mounting the SSH agent socket (SSH_AUTH_SOCK)
           // The SSH agent socket (SSH_AUTH_SOCK) is shared between outer feature devcontainer and inner feature test scenario container
            {
                "source": "${localEnv:SSH_AUTH_SOCK}",
                "target": "/tmp/ssh-agent.sock",
                "type": "bind"
            }
        ],
        "containerEnv": {
            "SSH_AUTH_SOCK": "/tmp/ssh-agent.sock"
        }      
    }
}
