Research direction
Start with the Dockerfile shown in the issue, especially the nginx:1.19.7-alpine base image and the wget command that reports a bad address for github.com. Reproduce the Docker build with the listed Docker and macOS versions, then determine whether the failure is specific to the image or build environment; done means the command resolves github.com successfully or the cause is documented.
