• Local OS Version: Windows 10.0.19044 Build 19044
• Local chip architecture:
• Reproduces in: <Remote - Containers>
• Corporate Proxy: yes
• Name of Dev Container Definition with Issue:

Steps to Reproduce:

1. Press "F1" > Select "Remote-Containers: Clone Repository in Container Volume" > Select: "Clone a repository from GitHub in a Container Volume"
2. Select Repo and branch
   Repo contains .devcontainer folder with Dockerfile with:

...
ENV HTTP_PROXY="${http://host.docker.internal}:${3128}"
ENV HTTPS_PROXY=...
...

Expectation:

• repo should be cloned and Devcontainer with proper setup should be created.

Observation:

• creating the temporary bootstap.Dockerfile failed even early before exact cloning step.

cc @chrmarti transferring from vscode-dev-containers to vscode-remote-release as I believe this is more extension specific.

Same issue here. Clone doesn’t use the devcontainer and dockerfile from the repo but bootstraps with a generic dockerfile/image. there should be a way to at least customize the bootstrapped dockerfile for cloning.

Additional information:
Environment: Dev Containers 0.255.4 in VS Code 1.72.2 (d045a5eda657f4d7b676dedbfa7aab8207f8a075)
Looks like operating with docker under cloned repository performed in the container
[139289 ms] Start: Run in container: docker volume ls -q
Therefore question: If I defined proxy settings on my host machine via .docker/config.json, including PROXY settings, will be this setting applied with operating with docker in bootstrap container?

Looks like it is exactly the issue - therefore no proxy are applied - everything is failing with error as:
#13 11.09 fatal: unable to access 'https://github.com/ohmyzsh/ohmyzsh/': Could not resolve host: github.com

Same Dockerfile (DevContainer) works perfectly if you first clone it locally and perform: "DevContiner:Open Folder in Container. "

I have the exact same issue, container creation with locally checked out repo works fine but "Clone a repository from GitHub in a Container Volume" fails.
At first it failed because the bootstrap image didn't have git-lfs installed even though its a feature in our devcontainer. After manually adding it to the bootstrap.Dockerfile it now fails with the Could not resolve host: ... errors although docker client is configured to use the proxy and is working for all other containers.
