Container Service for Kubernetes:Use ContainerOS

Last Updated:Jan 19, 2024

When you create a node pool in a Container Service for Kubernetes (ACK) cluster, you can select ContainerOS as the operating system of nodes. ContainerOS is simple and secure and is optimized for containers. ContainerOS is a lightweight Linux distribution intended for running containerized applications. ContainerOS contains only the required software packages and system services, which greatly improves system security and performance.

Prerequisites

An ACK cluster is created. The ACK cluster runs Kubernetes 1.24.6 or later and uses containerd. For more information about how to create an ACK cluster, see Create an ACK managed cluster. For more information about how to update an ACK cluster, see Update an ACK cluster.

Procedure

  1. Log on to the ACK console. In the left-side navigation pane, click Clusters.

  2. On the Clusters page, click the name of the cluster that you want to manage and choose Nodes > Node Pools in the left-side navigation pane.

  3. In the upper-right corner of the Node Pools page, click Create Node Pool.

  4. In the Create Node Pool dialog box, set Operating System to ContainerOS 3, configure other parameters, and then click Confirm Order.

    For more information about other parameters, see Create a node pool.
