The official cluster images provided by Sealos include the following:
- kubernetes: Kubernetes image with containerd as the container runtime interface (CRI).

Sealos offers different types of Kubernetes cluster images based on the container runtime interface (CRI):
- Kubernetes image with containerd as the CRI.
- Kubernetes image with Docker as the CRI.
- Kubernetes image with Crio as the CRI.
Users can choose the appropriate image type based on their requirements and preferences.
Sealos offers multiple versions of cluster images. Examples include:
1. Development Version
This version is suitable for users who want to try out the latest features of the project. The development version may contain new features and improvements that have not been thoroughly tested and may not be as stable.
2. Latest Version
The latest version is typically more stable than the development version but may not include all the new features. This version is recommended for most users.
3. Release Version (Including Historical Versions)
The release version includes historical versions. Release versions have usually undergone rigorous testing and are considered stable.
4.1.5 is the corresponding version number for Sealos.
When choosing an image version, users should consider their requirements and preferences. Additionally, Sealos provides sub-versions for different processor architectures to meet the needs of users on different hardware platforms.
