Looking into more detail on that one Redis Kubernetes Operator. Now I’m having trouble using it, so I try compiling it, but then I have trouble there too.

So, what’s the hold-up? When go build is used and CGO_ENABLED=0,
then Golang will try to cross-compile rebuild the standard libraries.
If you have your Golang installation in a root directory and you are
but a lowly user account, the recompile of the system libraries will
fail. So, what I found doing that got me past this issue was to
simply make my Golang installation writable by my user account, and
that allowed the compile to continue smoothly without issue. What
didn’t work: upgrading Golang. Nope, this is not actually a problem
that is magically fixed in the newer versions.

This is a pretty good blog post on cross compiling with Golang.

Again, I reiterate, because this is important! Kubernetes Operators require Custom Resource Definitions (CRDs), otherwise they can’t work at all.
