Clever Kubernetes Engine (CKE)

Clever Cloud allows you to create and manage Kubernetes clusters directly from Clever Tools. Once created and configured, you can use them with kubectl or any Kubernetes-compatible tool.

Prerequisites

Activate k8s feature flag to manage Kubernetes clusters:

clever features enable k8s

Then, check it works with the following command:

clever k8s

In all the following examples, you can target a specific organisation with the --org or -o option.

Create/Delete a Cluster

To create a Kubernetes cluster, you just need a name and you can wait for it to be in ACTIVE state:

clever k8s create myKubeCluster
clever k8s delete myKubeCluster --watch

To delete a cluster, use:

clever k8s delete myKubeCluster
clever k8s delete myKubeCluster --yes

List Clusters

If you have cluster, you can list them and know their name, ID and status with:

clever k8s list
clever k8s list --format json

Get Cluster information

To get information about a specific cluster, use:

clever k8s get myKubeCluster
clever k8s get kubernetes_id -F json

Classic response is a table:

┌─────────┬─────────────────────────────────────────┐
│ (index) │ Values                                  │
├─────────┼─────────────────────────────────────────┤
│ Name    │ 'myKubeCluster'                         │
│ ID      │ 'kubernetes_id'                         │
│ Version │ 1.34                                    │
│ Status  │ 'ACTIVE'                                │
└─────────┴─────────────────────────────────────────┘

Add persistent storage to a Cluster

You can add persistent storage to an ACTIVE cluster with:

clever k8s add-persistent-storage myKubeCluster

Once added you can’t remove it, but you can start a fresh cluster without persistent storage.

Get kubeconfig file of a Cluster

To get the kubeconfig file of an ACTIVE cluster, and set it as the current context, use:

clever k8s get-kubeconfig myKubeCluster
clever k8s get-kubeconfig myKubeCluster > ~/.kube/config
