Directions
Installing kubectl
Note:
If you have already installed kubectl, skip this step.
This step uses the Linux operating system as an example.
2. Execute the following commands in sequence to grant execution permissions.
sudo mv ./kubectl /usr/local/bin/kubectl
3. Execute the following command to check the installation result.
If the output is similar to the following version information, the installation was successful.
Client Version: version.Info{Major:"1", Minor:"5", GitVersion:"v1.5.2", GitCommit:"08e099554f3c31f6e6f07b448ab3ed78d0520507", GitTreeState:"clean", BuildDate:"2017-01-12T04:57:25Z", GoVersion:"go1.7.4", Compiler:"gc", Platform:"linux/amd64"}
Configuring kubeconfig
1. Log in to the TKE console, and choose Cluster from the left navigation bar. 2. On the cluster list page, click the ID of the registered cluster you want to connect to, to enter the management page of the cluster.
3. Choose Basic Information from the left navigation bar to enter the basic information page of the cluster.
4. In the Cluster APIServer Information, obtain the kubeconfig for either public network access or private network access, which you can copy or download.
5. Configure the cluster credential as needed. For details, see Connecting to the Kubernetes Cluster Through kubectl in the console.
Accessing the Kubernetes Cluster
1. After completing the kubeconfig configuration, execute the following commands in sequence to view contexts and switch the contexts to access the cluster.
kubectl config get-contexts
kubectl config use-context cls-3jju4zdc-context-default
2. Execute the following command to check whether the cluster can be accessed.
If you cannot connect to the cluster, check whether public network access or private network access is enabled, and ensure that the access client is in the specified network environment.
