I am making some modifications to jupyterlab source - specifically [jupyterlab/packages/services/src/kernel/kernel.ts at d3897d2d843fcf9632bc0305bba2a43383a5121a · jupyterlab/jupyterlab · GitHub](https://github.com/jupyterlab/jupyterlab/blob/d3897d2d843fcf9632bc0305bba2a43383a5121a/packages/services/src/kernel/kernel.ts)

I don’t have access to an npm registry and I need to maintain an internal fork of jupyterlab with this modification and distribute it within a Dockerfile. How do I build the dockerfile with this modification? Note: I will be including several other custom extensions along with this modified jupyterlab distribution within my docker image.
