kubernetes code-generator binaries docker:

script parts:

Makefile

modules.txt - go import paths for CRD specs
hack/boilerplate.go.txt - boilerplate text for generated code

build code-generator

docker buildx build --progress=plain  -f docker/Dockerfile -t code-generator:latest .

generate deepcopy, openapi

docker run -ti -v $(pwd):/data code-generator:latest
for PKG in core ldap; do PKG_VERSION=v1alpha1 make pkg=$PKG openapigen; make generate pkg=$PKG; done

generate client-go

create client-go structure

docker run -ti -v $(pwd):/data code-generator:latest
go mod init github.com/nevidanniu/sample-apispec/client-go
go get -x github.com/nevidanniu/sample-apispec

update api ver & generate client-go

docker run -ti -v $(pwd):/data code-generator:latest
cd client-go
rm -rf applyconfigurations ssp listers informers
