Kubespray v2.32.0 introduces breaking changes with Ansible 12 and Kubernetes 1.36

The Kubespray v2.32.0 release, as detailed in the project's GitHub release notes, sets Kubernetes 1.36 as the default minor version and upgrades the Ansible environment to Ansible 12 with ansible-core 2.19. This Ansible update introduces breaking changes to conditionals and templating, requiring operators to recreate or update their virtual environments using the provided requirements.txt file. Additionally, Node Feature Discovery defaults to version 0.19.0, and Helm defaults to version 3.22.0, with older checksums removed. The release also removes support for Debian 11 and macvlan on Debian, while introducing support for Ubuntu 26.04 and openSUSE MicroOS with containerd.

Operators should carefully review the Urgent Upgrade Notes before proceeding. The Ansible changes require updating boolean expressions and reviewing custom Jinja templates for compatibility, which may disrupt existing playbooks. Furthermore, deprecated inventory overrides for Node Feature Discovery, Helm, and Cilium Gateway API must be updated to avoid configuration errors. Systems relying on Debian 11 or Docker on Debian 13 must migrate to supported alternatives. Testing and validation of inventory overrides, templating, and system compatibility are critical to ensure a smooth upgrade without service disruptions.
