Deployments are not creating

Question

I am trying to create Deployment from client-go but it is not creating and throwing an error as

the server could not find the requested resource

My client-go version: 4.0.0

My Kubernetes version is:

Client Version:

version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.0", GitCommit:"fff5156092b56e6bd60fff75aad4dc9de6b6ef37", GitTreeState:"clean", BuildDate:"2017-03-28T16:36:33Z", GoVersion:"go1.7.5", Compiler:"gc", Platform:"linux/amd64"}

Server Version:

version.Info{Major:"1", Minor:"5", GitVersion:"v1.5.3", GitCommit:"029c3a408176b55c30846f0faedf56aae5992e9b", GitTreeState:"clean", BuildDate:"2017-02-15T06:34:56Z", GoVersion:"go1.7.4", Compiler:"gc", Platform:"linux/amd64"}

My sample code is

package main

"net"
)

var (
KubeMasterIP  = "x.x.x.x"
Port          = "xxxx"
UserName      = "xxxxx"
Password      = "xxxxxxxxxx"
TLSValue      = true
Protocol      = "https"
NameSpaceName = "test-namespace"
)

func main() {

fmt.Println("***************************")
buildAndDeployApp()
fmt.Println("***************************")
}

func buildAndDeployApp() {

tlsClientConfig := rest.TLSClientConfig{}
tlsClientConfig.Insecure = TLSValue
fmt.Println("HostPath: ", net.JoinHostPort(KubeMasterIP, Port))
restConfig := &rest.Config{
    Host:            net.JoinHostPort(KubeMasterIP, Port),
    Username:        UserName,
    Password:        Password,
    TLSClientConfig: tlsClientConfig,
}

cSet, err := kube.NewForConfig(restConfig)
if err != nil {
    fmt.Println("Error in Kube clientSet : ", err.Error())
}

deploy, err := cSet.AppsV1beta1().Deployments(NameSpaceName).Create(BuildDeployment())
fmt.Println("Deploy Output: ", deploy)
fmt.Println("Error: ", err)
}

func int32Ptr(i int32) *int32 { return &i }

Answer 1

apps/v1beta1 will not work in 1.5, its supported from 1.6. I used extensions/v1beta1 to access deployments in 1.5.
