VScode devcontainer can build from existing Dockerfile. You can develop the project image as usual, and then reference the Dockerfile from devcontainer.json. This means you can build and run from the command line via `docker` command if needed. The VScode extension just makes this slightly easier.

Not sure how GP's company does it, but that is how I would configure it.

Caveat: the default devcontainer initialization workflow does _not_ create the Dockerfile, only the .json.

At $work we don't use devcontainer.json, but we can launch the development environment image such that you can SSH into it as if it was a regular VM.
