Anysphere dev containers postCreateCommand not working as expected

Bug Reports

Describe the Bug

I am using postCreateCommand to automatically clone a private git repository that requires credential.

devcontainer.json: “postCreateCommand”: “sudo -E git clone $git_repo $workspace/$repo_name”

However, it is not able to get my credentials
fatal: could not read Username for ‘https://github.com’: No such device or address

same command works when creating container without postCreatCommand and running the command after creating.

Steps to Reproduce

devcontainer.json: “postCreateCommand”: “sudo -E git clone $git_repo $workspace/$repo_name”

Expected Behavior

Git repository should be cloned

Operating System

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hi @Dahyun_Jeon, – credentials are not currently forwarded when running the postCreateCommand. Could you clone manually after starting the container, or clone locally and use a mount for the repository?

Hi, I am currently walking around this issue by manually running the postCreateCommand in the container.
However it is little bit frustrating, moving from automated workflow to manual workflow.
