Description
Description:
When deploying the falcon-operator on a cluster with only system node pools tainted with CriticalAddonsOnly:NoSchedule, the operator manager pod cannot be scheduled there because the upstream manifest does not expose tolerations as a configurable value on the falcon-operator-controller-manager deployment.
Environment:
AKS cluster with system node pools carrying the CriticalAddonsOnly:NoSchedule taint. Operator deployed via ArgoCD using the published manifest bundled in a Helm chart.
The Problem:
The operator manager is critical infrastructure and belongs on system nodes. Without a CriticalAddonsOnly toleration it lands on workload nodes which are disposable and scale up and down. Patching the upstream manifest is not an option as it breaks clean upgrades and does not compose with ArgoCD when bundled in a Helm chart.

Research direction
Start with the published manifest and the falcon-operator-controller-manager deployment, then inspect the Helm chart that bundles them to find how deployment settings are exposed. Done means users can configure tolerations and nodeSelector without patching the upstream manifest, allowing the manager to schedule on tainted system node pools through clean upgrades.
