     1  Enhancement: Reduce the size of all the container images built on CI
     2  
     3  Previously, all images were based on golang:1.16 which is built from Debian.
     4  Using 'scratch' as base, reduces the size of the artifacts well as the attack
     5  surface for all the images, plus copying the binary from the build step ensures
     6  that only the strictly required software is present on the final image.
     7  For the revad images tagged '-eos', eos-slim is used instead. It is still large
     8  but it updates the environment as well as the EOS version.
