我正在尝试第一次将docker映像部署到kubernetes集群中，我有两个节点master和worker节点都处于启动和运行状态。

我创建了namesapace预发布环境，以在jenkins构建过程中部署我的更改，但我遇到了错误。

+ kubectl '--kubeconfig=****' '--context=K8sCluster-CC-pre-release' apply -f ./environment/pre-release '-n=pre-release'
error: context "K8sCluster-CC-pre-release" does not exist

stage('deployment') {
        container('kubectl') {

            withCredentials([kubeconfigFile(credentialsId: 'KUBERNETES_CLUSTER_CONFIG', variable: 'KUBECONFIG')]) {
            def kubectl
                if(gitBranch == "future-master-fix") {
                kubectl = "kubectl --kubeconfig=${KUBECONFIG} --context=K8sCluster-CC-pre-release"
                sh "${kubectl} apply -f ./environment/pre-release -n=pre-release"
                }   
            }
        }
      }



kubectl config set-context K8sCluster-CC-pre-release --namespace=K8sCluster-CC-pre-release --user=kubernetes-admin --cluster=kubernetes
Context "K8sCluster-CC-pre-release" created.

你能请人帮我吗？
