# We disable CGO here due to:
# 1) https://github.com/golang/go/issues/28065 that prevents 'go test' from running inside an Alpine container
# 2) https://stackoverflow.com/questions/36279253/go-compiled-binary-wont-run-in-an-alpine-docker-container-on-ubuntu-host which
#       which prevents from just switching to the Buster build image
# Sadly, this is slower: https://stackoverflow.com/questions/47714278/why-is-compiling-with-cgo-enabled-0-slower
