GCR-Image not using included static HTML

This is the repository:

  • https://github.com/WebMobileDeveloper88/app-go
    I created the image with waypoint build und deployed it as GCR Service.
    When inspecting the image with local Docker Desktop the static HTML-page is inside.
    When running the image as Google Cloud Run Service the default static HTML-page from HashiCorp is used.
    Strange behaviour…
