How to Manage Nodes and Node Pools

Objective

OVHcloud Managed Kubernetes service provides you Kubernetes clusters without the hassle of installing or operating them. This guide will cover one of the first steps after ordering a cluster: managing nodes and node pools.

Requirements

  • An OVHcloud Managed Kubernetes cluster

Nodes and node pools

In your OVHcloud Managed Kubernetes cluster, nodes are grouped into node pools (group of nodes sharing the same configuration).

When you order a new cluster, it is created with a default node pool. Refer to our guide on creating a cluster for more information.

In this guide, we explain how to do some basic operations with nodes and node pools using the Public Cloud section of the OVHcloud Control Panel.

Instructions

Access our administration UI for your OVHcloud Managed Kubernetes clusters by clicking on Managed Kubernetes Service in the left-hand menu in the Public Cloud section of the OVHcloud Control Panel. In the table, select a cluster by clicking on the cluster name.

In this administration UI, you have several tabs:

  • Service: Here you will have a global view of your cluster with important information like the status, the API URL, or the kubectl configuration file.

  • Node pools: Here you will find the active node pools of your cluster. You will be able to add, resize, or remove node pools.

  • APIServer access: You can add IPv4 ranges in order to restrict access to your cluster’s APIServer.

  • Audit Logs: Here you will find the logs for your Kubernetes cluster’s control-plane.

Configuring a node pool

To access the nodes configuration, switch to the Node pools tab. Click on the ... button in the row of the node pool concerned. Then, select See nodes.

Here you can change the billing method for a node or delete a node by clicking on the respective ... button of a node.

Adding nodes to an existing node pool

In the Node pools tab, click on the ... button in the row of the node pool concerned. Then, select Configure node pool size.

In the popup window, you can resize your node pool by adding nodes. You can alternatively enable the autoscaling feature which allows you to set the minimum and maximum pool size instead.

Creating additional node pools

In the Node pools tab, click on the Add a node pool button.

Fill out the required fields to create a new node pool.

The name of node pool should be in lowercase. The “_” and “.” characters are not allowed. The node pool name cannot begin with a number.

The subsequent node pool configuration steps are described in Creating a cluster.

Deleting a node pool

In the Node pools tab, click on the ... button in the row of the node pool concerned, then select Delete pool.

Confirm the decision by typing DELETE into the field. Then, click the Delete button.
