Abdelfettah Sghiouar, Senior Developer Advocate at Google, shared his thoughts on Kubernetes multi-tenancy and that not all tools are designed with multi-tenancy in mind.
Abdel suggested an alternative approach involving a shared control plane with single node pools per tenant. This method allows for the deployment of tenant-specific tools, although it might not fully leverage Kubernetes' capabilities.
