Cloud Shell is a web-based command-line tool provided by Alibaba Cloud. You can use Cloud Shell to run commands in a browser to manage Alibaba Cloud resources. This topic describes how to use kubectl on Cloud Shell in the Container Service for Kubernetes (ACK) console to manage ACK clusters.
Prerequisites
Cloud Shell can connect to ACK clusters only from the Internet. Therefore, you must make sure that the API server of the cluster that you want to manage is accessible over the Internet. For more information, see Control public access to the API server of a cluster.
Background information
Cloud Shell is a web-based command-line tool. When you start Cloud Shell, Cloud Shell automatically creates a Linux VM for you. The Linux VM is free of charge. The VM is pre-installed with cloud management tools and system tools. You can use these tools with Web IDE provided by Cloud Shell to manage cloud resources. For more information, see What is Cloud Shell? .
When you open Cloud Shell in the ACK console, the system automatically loads the kubeconfig file of the cluster. Then, you can use kubectl to manage the cluster.
Procedure
Log on to the ACK console. In the left-side navigation pane, click Clusters.
On the Clusters page, find the cluster that you want to manage and choose in the Actions column.
Optional: Click the
icon and then click Mount File Storage. You can associate and mount an File Storage NAS (NAS) file system to persist files and scripts that are commonly used. This way, the files and scripts are not deleted when the NAS file system is released. You can click Create Now or Skip based on your requirements.
Run the following command to query the namespaces in the cluster:
kubectl get namespaceExpected output:
NAME STATUS AGE default Active 3h14m kube-node-lease Active 3h14m kube-public Active 3h14m kube-system Active 3h14m
