We’ve updated our Kubernetes platform. Version 1.30 is supported, and version 1.31 is now in preview.

Updating to a newer version ensures you have access to the latest bug fixes and enhancements, which can help prevent potential issues and improve your overall experience.


‍ We currently support Kubernetes 1.30, which means it has undergone rigorous testing and is deemed stable for production use. On the other hand, Kubernetes 1.31 is still in preview, indicating that it’s a newer release that hasn’t yet completed thorough testing and validation. While we’re excited about the new features and capabilities of version 1.31, we recommend waiting until it reaches general availability before deploying it to production environments. You can get started with Kubernetes on Leafcloud here.

Now that we’ve gotten that out of the way, let’s dive into the changes.


1.30 supported: features, changes

Version 1.30 of Kubernetes brings with it several upgrades and feature enhancements. Some key features and changes include:

  • Container Resource Based Pod Autoscaling has graduated to stable, refining the Horizontal Pod Autoscaler’s capabilities.

  • User Namespaces in Pods has moved to beta, enhancing pod security by supporting customized UID/GID ranges.

  • The introduction of Structured Parameters for Dynamic Resource Allocation, improving resource management within clusters.

  • A new ‘sleep’ action for the PreStop lifecycle hook, which is graduating to beta.

  • Node Memory Swap Support is undergoing major changes in its beta stage.

  • The kubelet now supports configuring IDs used to create user namespaces.

  • AppArmor profiles can now be configured through fields on the PodSecurityContext and container SecurityContext.
