Kubernetes - Quickstart

Scaleway Kubernetes Kapsule and Kosmos provide a managed environment to create, configure and run a cluster of preconfigured machines for containerized applications. This allows you to create Kubernetes clusters without the complexity of managing the infrastructure. You can create a Kapsule cluster to your required specifications, edit it after creation and delete it all when you no longer need it.

How to create a Kubernetes cluster

1. Click Kubernetes in the Containers section of the side menu. The Kubernetes Kapsule dashboard displays.
2. Click Create cluster. The first page of the cluster creation wizard displays.
3. This page concerns the configuration of your cluster. Enter the following information:
   • The cluster type. It can either be a:
     • Kubernetes Kapsule cluster. It allows you to create clusters using exclusively Scaleway Instances, from the smallest development Instance to our GPU offers, including features such as node auto-healing and pools auto-scaling.
     • Kubernetes Kosmos cluster. Kubernetes Kosmos is the first managed Kubernetes engine that allows you to attach an Instance or dedicated server from any Cloud provider to a Scaleway Kubernetes control plane.
   • The geographical region of the cluster.
   • The Kubernetes version for the cluster.
   • The name for the cluster and optionally a description, tags, which can help you to organize your cluster.
4. • If you are creating a Kubernetes Kapsule cluster, click Next. The second page of the cluster creation wizard displays.
   • If you are creating a Kubernetes Kosmos cluster, click Create cluster to create cluster without any pools. You can add them to the cluster later. Otherwise, click Add and configure a Pool to configure a node pool for your cluster.
5. This page concerns the settings for your pool if you create a Kubernetes Kapsule cluster or if you want to use Scaleway nodes for your cluster with Kubernetes Kosmos. Enter the following information:
   • The availability zone in which all your pool’s nodes will be created
   • The node type you require
   • The configuration for your node options, including the number of nodes and whether to enable autoscale. You can also choose whether to enable auto-heal and whether to link the cluster to a placement group. Alternatively, you can leave these options at default values.
6. Click Create cluster.

How to add a Scaleway pool to a Kubernetes Cluster

1. Click Kubernetes in the Containers section of the side menu. The Kubernetes dashboard displays.
2. Click «See more Icon» next to the cluster you want to edit. Click Add pool in the menu. The pool configuration wizard displays.
3. This page concerns the configuration of your cluster. Enter the following information:
   • The pool type for the pool: Scaleway
   • The geographical region of the pool.
   • The node type for the pool.
   • If required configure the node options like autoscaling, autohealing, or link the pool to an existing placement group.
   • The name for the pool. Optionally you can assign tags to it.
4. Click Add pool.

How to add a Muti-Cloud pool to a Kubernetes Cluster

1. Click Kubernetes in the Containers section of the side menu. The Kubernetes dashboard displays.
2. Click «See more Icon» next to the pool you want to edit. Click Add a pool in the menu. The pool configuration wizard displays.
3. Click Add Pool.

How to add external nodes to a Multi-Cloud pool

1. Click Kubernetes in the Containers section of the side menu. The Kubernetes dashboard displays.
2. Click «See more Icon» next to the cluster you want to edit. Click More info in the menu. The cluster dashboard displays. Click the Pools tab.
3. Click «See more Icon» next to the pool you want to edit. Click More info in the menu. Click Add node in the menu. The node information page displays.
4. This page provides information on how to add your external node to the pool. Connect to your node and run the following command to add the node:

   $> wget https://scwcontainermulticloud.s3.fr-par.scw.cloud/multicloud-init.sh && chmod +x multicloud-init.sh
   $> ./multicloud-init.sh -p c58bcee3-52db-4501-a96e-41dddbb6e5f4 -r fr-par -t SCW_SECRET_KEYCopy

How to edit a Kubernetes cluster

1. Click Kubernetes in the Containers section of the side menu. The Kubernetes dashboard displays.
2. Click «See more Icon» next to the cluster you want to edit.
3. Choose the option you require:
   • More info: See detailed information about the Cluster
   • Add pool: Add additional computing resources to the Cluster
   • Get kubeconfig: Download the .kubeconfig file of the Cluster
   • Delete: Delete the Cluster

How to delete a Kubernetes cluster

1. Click Kubernetes in the Containers section of the side menu. The Kubernetes dashboard displays.
2. Click «See more Icon» to display the options menu, then click Delete. A cluster deletion pop-up displays.
3. Type DELETE to confirm the deletion of your cluster. Tick the checkbox to automatically delete all volumes (including those with volume type “retain”) and Load Balancers whose names start with cluster ID. Valitate your choice by clicking Delete cluster.
   Important:

   Deleting your cluster will permanently destroy your cluster and all its associated pools and Instances. External compute resources cannot be destroyed automatically and will remain active until destroyed at the concerned cloud service provider (CSP).
