I have a question regarding kubebuilder configuration - which version of the kubebuilder api does the application use? Basically the /usr/local/kubebuilder/bin/etcd is missing for envtest. I have configured kubebuilder regarding the latest documentation, and there was no information about downloading etc whatsoever. If you can point me out to the configuration that is needed to be done additionally, I'd be very grateful

You should install setup-envtest: go install sigs.k8s.io/controller-runtime/tools/setup-envtest@latest
then download all needed bins with exporting the path to those bins.:

export KUBEBUILDER_ASSETS=$(setup-envtest use 1.25.0 --bin-dir ${BINARY_DIR} -p path)

Install libgit2-dev from alpine in version 1.5.*: https://pkgs.alpinelinux.org/packages?name=libgit2-dev&branch=v3.18&repo=&arch=&maintainer=

Also builiding requires apk add --no-cache gcc libc-dev
