Overview

This document describes two types of images supported by TKE and their respective use cases and instructions. For more information, see Image Types.
Note:
TKE provides SLA guarantees only for public images.
For custom images in non-standard operating environments without TKE's compatibility adaptation, you need to ensure the image availability in Kubernetes environments. In principle, TKE does not provide SLA and technical support for these images.
Public image: They are images officially provided by Tencent Cloud. Each image contains an operating system and initialization components provided by Tencent Cloud, and is available to all users.
Custom image: It is created by using the image creation feature or imported by using the image import feature. A custom image is only available to the creator and the people they share it with. It is a non-standard environment that doesn't come with official support and ongoing maintenance from Tencent Cloud.

Limits

There are two levels of operating systems, including cluster level and node pool level.
OS configured at the cluster level is used when creating a node, adding an existing node, and upgrading a node in a cluster.
When adding existing nodes or expanding the node capacity inside the node pool, you will use the OS at the node pool level.
Changes to the OS only apply to new nodes and reinstalled nodes, but not existing nodes.

List of Public Images Supported by TKE

TKE offers the following public images that you can choose as needed.
Note:
Whenever TKE plans to adjust the image logic, we will notify you at least one week in advance via Message Center, SMS, and email. Image logic changes will not affect the existing nodes previously created by using an earlier image. For better results, we recommend you use a later basic image.
