Guide for autogeneratng client codes for Kubernetes Custom Resource Definitions (CRD)

Steps:

• take the configuration in directory in pkg/apis/foo.com/ as template to define the new crd"

• Disable go modules

export GO111MODULE=off

• Download the generator repository

 go get k8s.io/code-generator

• Download this repository

go get github.com/afarid/kubernetes-crd-example/pkg/apis/foo.com/v1

• Run this command inside this project directory:

cd $GOPATH/src/github.com/afarid/kubernetes-crd-example
../../../k8s.io/code-generator/generate-groups.sh all "github.com/afarid/kubernetes-crd-example/pkg/clients" "github.com/afarid/kubernetes-crd-example/pkg/apis" "foo.com:v1" -h ../../../k8s.io/code-generator/hack/boilerplate.go.txt

After running the above command, you will see a new directory pkg/clients/.

• use generated package in your code, this is an example of how to use the generated package

package main

import (
	clientset "github.com/afarid/kubernetes-crd-example/pkg/clients/clientset/versioned"
)

func main() {
	_, _ = clientset.NewForConfig(nil)
}
