Cluster hosting

Kubeadm cluster hosting

For a host cluster created and managed by kubeadm, kubeclipper gets the cluster and node information from the kubeconfig file and imports it into the kubeclipper platform.

Click “Cluster Management” > “Cluster Hosting” button to enter the cluster hosting page. Click “Add” button at the upper left corner. In the pop-up window of Add Provider, fill in the provider name (such as kubeadm-demo) and description, and then fill in the following information:

• Region: The region of the cluster and node in the kubeclipper platform.

• Provider type: Select kubeadm.

• SSH: Specifies the connection method of cluster nodes. Private Key or Password can be selected. Ensure that all cluster nodes can be connected through the selected method.

  • Private Key: enter the node user name and private key information.
  • Password: enter the node user name and password.

• Cluster name: Specifies the display name on the platform and cannot be the same as any other clusters.

• KubeConfig: The KubeConfig file of the host cluster.

Click the “OK” button to import the cluster and node into the platform. Click the provider name (kubeadm-demo) to enter the Provider detail page, where you can view the cluster under the provider and perform the following operations on the provider:

• Synchronization: Kubeclipper synchronizes cluster information every four hours. You can also click “Synchronize” to manually perform the operation.
• Edit: Edit the provider’s name, description, access information, and node connection method.
• Remove: Remove the cluster information from kubeclipper, but the cluster will not be uninstalled.

Managed cluster management

You can choose “Cluster Management” > “Cluster” to go to the cluster list page and view the list of all clusters, including hosted clusters and local clusters. The following table lists the operations supported by different clusters:

Note that “docker.io” will be used as image resource by default when you install external storage and other plug-ins for host clusters. If you are in an offline environment, you need to fill in the address of the accessible private registry during plug-in installation. The private registry must be added to the CRI registry of the cluster. For details, refer to CRI Registry.
