Overview
This document describes three 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.
Custom and marketplace images are non-standard operating environments. TKE has not undergone compatibility adaptation for these images, and users are responsible for ensuring their usability in a Kubernetes environment. In principle, TKE does not provide SLA services or technical support for such 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.
Market image: It is provided for specific use cases, such as qGPU sharing. It is available to all users and integrated with certain applications in addition to the operating system.
Supports and 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
If TKE plans to adjust the image logic in the future, we will notify you at least one week in advance via site messages, text messages, and emails. Please feel confident using the service. Changes in image logic will not affect existing nodes created with older image versions. For optimal results, we recommend using the latest base images.
