Extensions are not installed from .devcontainer in Insiders

[neuromechanist]

Issue Type: Bug

I have a .devcontainer that runs pulls a docker image (without a dockerfile) and starts the container. However, the extensions won't install on the VS Code Insiders, while there is no problem when I open the same .devcontainer (and the same workspace, everything) in the Stable VS Code.

I have my settings sync on as well on both versions as well. I already tried this on three different systems and I got the same result for both Insiders and Stable VS Code. Please find the output of the Insider and Stable container build process at the end of the post.

To reproduce, I think you can use my .devcontainer to re-recreate the container. The image is a little huge though (>6GB). I can't reproduce this problem without extensions because remote extensions are required.

VS Code version: Code - Insiders 1.52.0-insider (24b28f57be22fe3029cb17a1dd72d8d9c2d6468b, 2020-11-06T05:43:01.017Z)

@neuromechanist It looks like /root/.vscode-server-insiders/data/Machine/.installExtensionsMarker already existed (and we therefore skipped the extension install). Did you mount anything there or a parent folder?

[neuromechanist]

Yes, there was .installExtensionsMarker on that path, and removing the marker solved the issue, thanks.

However, I have not mounted (or touched anything in that directory), because I was not aware of that actually. Also, I made the container image from an anaconda image and installed additional packages from my YAML recipe. So, I am not sure how this marker found its way there.

Thanks again for your help. I'll close this issue.

[chrmarti]

The marker file is created at the start of the extension installation. If the installation fails and you reload the window, it will not retry. That is to not block startup forever. You can then rebuild the container to retry extension installation.
