Cozystack v1.7.0-alpha.1 introduces breaking changes to worker pools

Cozystack v1.7.0-alpha.1, as detailed in the project's GitHub release notes, introduces significant changes to the handling of worker pools. Worker pools are now first-class objects, moved out of the Kubernetes chart into separate KubernetesNodes resources. This shift removes the spec.nodeGroups field from the Kubernetes CR, and migration 52 is designed to adopt existing pools during the upgrade. Once separated, worker pools gain new capabilities such as setting CPU requests and limits, logging guest serial consoles, and routing image pulls through registry mirrors. Additionally, the addons.fluxcd option has been removed, with migration paths provided for tenant clusters that previously used it.

Operators considering this alpha build should carefully evaluate the impact of these breaking changes on their existing configurations. Specifically, any automation or tooling relying on the spec.nodeGroups field must be updated to accommodate the new KubernetesNodes structure. Similarly, tenant clusters that utilized the FluxCD addon need to ensure their upgrade path aligns with the migration provided. This alpha release is not intended for production environments, and operators should test thoroughly in isolated environments to confirm compatibility and functionality before considering broader deployment.
