devcontainer build fails with authentication error

Hi everyone,

I’ve been using the build feature of the devcontainer CLI before and didn’t have any issues until recently.

Now when I try to build my devcontainer configuration I receive the following error:

I’m logged into Docker hub and can pull other images with no problem. Any ideas what could be the issue here?

Actually the workaround of using BuildKit will not work for Docker Compose at the moment (that won’t switch to using buildx). Preparing a fix that will simply skip --pull when we use that temporary image with docker build.

Another workaround is to not use --no-cache (--pull is only added when that is set).

Fixed in Remote-Containers 0.241.2-pre-release and Dev Containers CLI 0.7.1.

(The workaround would be to not use --no-cache.)

Just tested CLI version 0.7.1. Works again, thanks for fixing! ❤️
