Node feature discovery for Kubernetes
6149000637
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. |
