Question

我是kubernetes工具的新手，我正尝试使用docker + kubernetes部署Angular应用程序，这里是下面的Jenkins脚本。

stage('Deploy') {
       container('kubectl') {        
            withCredentials([kubeconfigFile(credentialsId: 'KUBERNETES_CLUSTER_CONFIG', variable: 'KUBECONFIG')]) {
            def kubectl
               kubectl = "kubectl --kubeconfig=${KUBECONFIG} --context=demo"
               echo 'deployment to PRERELEASE!'
               sh "kubectl config get-contexts"
               sh "kubectl -n demo get pods"
               sh  "${kubectl} apply -f ./environment/pre-release -n=pre-release"
               } 
            }
            }
    }

请找到以下詹金斯输出

现在的问题是，在部署之后，我无法使用以下命令在两台计算机的主计算机中看到吊舱和部署，请您帮我成功部署后如何访问应用程序。

kubectl get pods
kubectl get services
kubectl get deployments

Answer 1

您正在运行pre-release时将名称空间设置为"${kubectl} apply -f ./environment/pre-release -n=pre-release"。

要在此命名空间中获取pod，请使用：kubectl get pods -n pre-release。

命名空间是一种在单个物理Kubernetes集群中分离不同虚拟集群的方法。有关更多详细信息，请参见https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/。

Answer 2

运行以下命令时，您正在使用pre-release选项在名为-n的命名空间中创建资源。

kubectl '--kubeconfig=****' '--context=demo' apply -f ./environment/pre-release '-n=pre-release'
deployment.apps/frontend-deploy unchanged

您需要列出相同命名空间中的资源。

kubectl get pods -n pre-release
kubectl get services -n pre-release
kubectl get deployments -n pre-release

默认情况下，kubectl将在default名称空间中执行请求的操作。如果要将当前名称空间设置为pre-release，而不必在每个kubectl命令后附加-n pre-release，则可以运行以下命令：

kubectl config set-context --current --namespace=pre-release
