Scaleway Elements Kubernetes Kapsule provides a managed environment to create, configure and run a cluster of preconfigured machines for containerized applications. You will be able to create Kubernetes clusters without the complexity of managing the infrastructure.
The service offers full flexibility such as:
To administrate your Kubernetes Cluster easily, Scaleway provides a
.kubeconfig file that allows you to manage your cluster from your local computer by using
kubectl. Kubectl is the command line interface for running commands against Kubernetes clusters.
To learn more about Scaleway Elements Kubernetes Kapsule, refer to the FAQ.
Scaleway also offers Kubernetes Kosmos which allows you to attach instances or dedicated servers from other Cloud providers to your cluster. For more information about Kubernetes Kosmos, refer to our dedicated documentation

Kubernetes is an extensible open-source platform, built to manage containerized workloads and services. For more detailed information, refer to our Introduction into Kubernetes and the official documentation.
A cluster is a set of machines, called nodes, running containerized applications managed by Kubernetes. The Kubernetes Control Plane and associated load balancers are managed by Scaleway. A cluster has several worker nodes and at least one control plane. Each cluster is built for High Availability with a redundancy on the Control Plane.
Consider the following when creating a Control Plane:
The Pool resource is a group of compute instances, organized by type (e.g., GP1-S, GP1-M). A pool is made up of nodes comprising Scaleway compute instances, unless it is a Multi-Cloud Pool in which case it can include nodes from other Cloud providers.
It represents the computing power of the cluster and contains the Kubernetes nodes, on which the containers run.
Consider the following when creating a Pool:
Load balancing refers to efficiently distributing incoming network traffic across a group of backend servers. Scaleway services manage the traffic between the API masters. As a user, the load balancer is a service entirely managed by Scaleway.
Namespaces are used in Kubernetes to divide cluster resources between multiple users. For detailed information, refer to Kubernetes official documentation on Namespaces
An API object that manages external access to the services in a cluster, typically HTTPS. Ingress can provide load balancing, SSL termination and name-based virtual hosting.
1 . Sign in to your Scaleway account
2 . Click Kubernetes on the side menu. The Kubernetes Kapsule page is displayed.
3 . Click Create a cluster.
The first page of the Cluster Creation Wizard displays. This concerns the configuration of your cluster.
4 . Complete the following steps of the wizard:
Choose a Cluster Type. This can be a Scaleway Kubernetes Kapsule or Kubernetes Kosmos.
Note: This document concerns the creation and management of a Scaleway Kubernetes Kapsule. For Kubernetes Kosmos, refer to the dedicated documentation
The second page of the Cluster Creation Wizard displays. This concerns the settings for your pool.
6 . Enter:
7 . Click Create a cluster
Your cluster is deployed
Once your cluster is created, it appears in the Clusters List.
Several options are available from the pop-up menu on the cluster list page:
.kubeconfigfile of the Cluster
To view your cluster information, click on the cluster itself. The cluster overview page provides several pieces of information:
If you click on the Pools tab, you are able to add, edit or delete a pool on your cluster.
If you click on the Nodes tab, you are able to reboot or replace nodes on your cluster.
Once the cluster is created, a
.kubeconfig file is available for download to manage several Kubernetes clusters. You can use this with kubectl ,the Kubernetes command line tool, allowing you to run commands against your Kubernetes clusters. You can use kubectl from a terminal on your local computer to deploy applications, inspect and manage cluster resources, and view logs.
2 . Download the
.kubeconfig files from your Cluster’s Overview page:
3 . Configure access to your cluster. You can do this in one of two ways:
KUBECONFIG environment variable:
use $HOME/.kube/config file:
mv $HOME/Downloads/Kubeconfig-ClusterName.yaml $HOME/.kube/config
Either way, make sure you replace
/$HOME/Downloads/Kubeconfig-ClusterName.yaml with the correct name and path of your downloaded
4 . Run the following command to finish:
kubectl get nodes
You can access the Kubernetes Dashboard direclty from the Scaleway console. The Kubernetes Dashboard is a web based interface that displays the state of Kubernetes resources in your cluster as well as errors that may have occurred.. You can also deploy new containerized applications or troubleshoot your existing ones from the web interface.
From Your clusters overview page, click Dashboard:
The Kubernetes Dashoboard opens in a new browser tab:
An Ingress Controller is an entry point that ingests your HTTP/HTTPS traffic and dispatches it to your services. More precisely, it is a reverse proxy that will dynamically configure itself and will forward HTTP/HTTPS traffic to your services.
It is possible to configure an Ingress Controller during cluster creation. Click on Advanced Options and click on Yes to enable the Ingress Controller. It is possible to setup
kubectl get nodes -o wide
Kapsule presents the following limitations:
/etcfolder on Kubernetes Kapsule nodes might be used for internal cluster actions. Prefer
/datafor local storage, even though local storage is not recommended in stateless Kubernetes clusters.
