Manage a cluster

View the list of clusters

On the Kubernetes Management page, you can view and manage the list of existing Kubernetes clusters. To open Kubernetes Management, follow these steps:

In the FPT Portal menu, select Kubernetes. The system displays a list of existing clusters organized by Name, Version, Worker Group, Type, Status, Creation Date, and Action.

Accessing Cluster Details

Step 1: Select Kubernetes from the menu to display the Kubernetes Management page. Select the cluster for which you want to view details.

Step 2: The cluster information is displayed on the [Essential Properties] tab.

• Cluster Information: Basic cluster information includes the cluster name, Kubernetes version, Kubernetes configuration file, status, purpose of the SSH key file, and auto-upgrade version (if enabled).

• Load Balancer VIP: Information about the selected load balancer size.

• Worker Group Settings: List of groups and settings Worker Nodes: Minimum/maximum count, CPU, memory, disk.

• API: API URL for the cluster.

Step 3: The [Node Pools] tab displays all worker groups belonging to the cluster and the configuration information for each worker group.

• Name: Worker group name

• Is Based: Display (ü) if worker-based, (û) if not worker-based

• Instance Type: Display the instance type (CPU or GPU)

• Resource Type: Display the amount of CPU and RAM

• Disk: Display disk capacity

• Policy: Display information about the selected storage policy

• Auto Scale: Displays (ü) if auto scaling is enabled, (û) if disabled

• Min Node: Displays the minimum number of worker node VM instances configured for the worker group.

• Max Node: Displays the maximum number of worker node VM instances configured for the worker group.

• Action: Users can delete worker groups that are no longer in use. Note: Worker group bases cannot be deleted

Obtaining Cluster Access Information

Step 1: Select "Containers" > "Kubernetes" from the menu to display the Kubernetes Management page. Select the cluster whose information you want to access.

Step 2: Under Essential Properties > Cluster Information > Configuration, download the kubeconfig file to log into the cluster using tools like kubectl.

Tip: M-FKE uses Native Kubernetes, allowing users to manage the cluster using kubectl and dashboard tools just like a standard Kubernetes cluster.

Kubeconfig Rotation

When using a Kubernetes cluster, you can perform a kubeconfig rotation. Example: When you need to change the certificate for user authentication

Step 1: Select [Containers] > [Kubernetes] from the menu to display the Kubernetes Management page.

Step 2: Select [Renew kubeconfig] under [Configuration] in the [Essential Properties] tab.

Step 3: Review the warning information in the pop-up and click the [Renew] button.

Deleting a Kubernetes Cluster

Unneeded Kubernetes clusters can be deleted using the following steps.

Step 1: Select [Containers] > [Kubernetes] from the menu to display the Kubernetes Management page.

Step 2: From the list, select [Action] at the end of the cluster you want to delete. Select [Delete].

Step 3: Review the warning information in the pop-up and select "Delete".
