kubernetes.core 6.4.0 collection release adds Helm v4 compatibility and improved k8s_drain check mode. Upgrade guide with practical examples.

Introduction

The kubernetes.core 6.4.0 collection has been released with two significant improvements: Helm v4 compatibility across all Helm modules and enhanced k8s_drain behavior with check mode support.

This update is important for teams using Ansible to manage Kubernetes clusters, especially those planning to adopt Helm v4.

FAQ

Is kubernetes.core 6.4.0 included in Ansible 13.6.0?

Check with ansible-galaxy collection list kubernetes.core. If your version is older, upgrade manually with ansible-galaxy collection install kubernetes.core:==6.4.0 --force.

Does Helm v4 support require changes to my existing playbooks?

No. The 6.4.0 update adds forward compatibility — existing Helm v3 playbooks continue to work without modification.

What Python packages are required?

The kubernetes.core collection requires the kubernetes Python package and optionally helm CLI for Helm modules.

Conclusion

kubernetes.core 6.4.0 is a solid release that prepares your Ansible-Kubernetes automation for the Helm v4 era while improving operational safety with better drain handling. Upgrade your collection to take advantage of these improvements.
