Markus Lehtonen 6149000637 Build statically linked binaries 
Switch to fully statically linked binaries and use scratch as a base
image.

Switching to the virtually empty scratch base image means that the
default/minimal NFD image only supports running hooks that are truly
statically linked (e.g.  normal go binaries that are "almost" statically
linked stop working).  The documentation has been already stating this
(i.e. that only statically-linked binaries are supported) - i.e. we have
had no promise of supporting other than that. Also, hooks are now
deprecated and even disabled by default so the possibility of real user
impact should be small.

Image variants

{: .no_toc}

NFD currently offers two variants of the container image. The "minimal" variant is currently deployed by default. Released container images are available for x86_64 and Arm64 architectures.

Minimal

This is a minimal image based on scratch and only supports running statically linked binaries.

For backwards compatibility a container image tag with suffix -minimal (e.g. {{ site.container_image }}-minimal) is provided.

Full

This image is based on debian:bullseye-slim and contains a full Linux system for running shell-based nfd-worker hooks and doing live debugging and diagnosis of the NFD images.

The container image tag has suffix -full (e.g. {{ site.container_image }}-full).
