Incorrect workspace copy, causing host/container repo sync issue

[shreyansp]

Thanks for sharing this example. There is one mistake in it though. It took me a couple hours to figure out, using this example, why my git repo in devcontainer was not in sync with that on my host. It's because of your last line COPY . /workspace.

I thought the whole point of dev containers is that so the workspace from your host and container is shared (by mounting it), not copied!

The dev container docker image that Microsoft provides, mcr.microsoft.com/vscode/devcontainers/python:0-${VARIANT}, creates a mount correctly, but then I guess your COPY command overwrites this and creates a static snapshot view of the repository from the host at the point in time when the image is created.

Removing this line fixes everything. Thank you!
