I'm trying to preconfigure a private container registry in a CodeSpace so workshop participants can use it.

• I have rebuilt the codespace
• I tried a different prefix than GH_ to no avail.

If I read the docs correctly, this should make sure docker can pull from ghcr using my credentials, but all I get is an error:

codespace ➜ /workspaces/attendee-jessehouwing (main) $ docker pull ghcr.io/xxxxx-customers/xxxxx-cli
Using default tag: latest
Error response from daemon: Head "https://ghcr.io/v2/xxxxx-customers/xxxxx-cli/manifests/latest": unauthorized

I searched the vscode-container repository for a hint to something I may have to configure on my custom container, but I don't really see anything wrong.

Custom container dockerfile:

FROM mcr.microsoft.com/vscode/devcontainers/universal:1-linux

USER codespace
    
RUN az extension add --name azure-devops

I tried in the standard vscode container and see the same behavior. I must be doing something wrong.

The secrets are registered in the same repository as a set of repository secrets and I'm launching the codespace from the same repo:

A few questions to try and unblock you -

1. Have you ensured that your secrets are available to the repository you're creating the codespace off of? You can click "Update" to see which repos have access to these secrets.

   Then rebuild the Codespace.
