nsc base-image build-github-image

Test the build of a base image.

base-image build-github-image performs a test build of a Dockerfile intended for use as a GitHub Actions runner base image. It's useful for validating that a custom image configuration builds successfully before you upload it or wire it up to a GitHub runner profile. This command is also invokable as nsc github build-base-image — both forms run the exact same command, so don't be confused if you see either one referenced elsewhere.
