23-30: RBAC permissions look good!The new rule follows the principle of least privilege by:
- Limiting operations to read-only actions (get, list, watch)
- Specifically scoping resource names to redis and sentinel components
Let's verify that these are the only workloadmonitor resources in the redis namespace:
✅ Verification successful
✅ RBAC permissions correctly cover all WorkloadMonitor resources
The resourceNames in the RBAC rule exactly match the two WorkloadMonitor resources defined in
redisfailover.yaml:
{{ .Release.Name }}-redis{{ .Release.Name }}-sentinel🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Verify no other workloadmonitor resources exist in redis templates rg -g '*.yaml' -l 'kind:\s*WorkloadMonitor' packages/apps/redis/templates/Length of output: 125
Script:
#!/bin/bash # Extract WorkloadMonitor resource names from redisfailover.yaml rg -U 'kind:\s*WorkloadMonitor[\s\S]*?name:.*' packages/apps/redis/templates/redisfailover.yamlLength of output: 234
packages/apps/kubernetes/templates/dashboard-resourcemap.yaml (1)
27-36: RBAC configuration is well structured!The new rule properly:
- Uses templating to dynamically scope resource names based on nodeGroups
- Maintains read-only access appropriate for dashboard usage
packages/apps/redis/templates/redisfailover.yaml (1)
78-91: Redis WorkloadMonitor configuration looks good!The monitor properly aligns with the RedisFailover spec:
- Uses same replica count
- Correctly selects redis component using labels
packages/apps/kubernetes/templates/cluster.yaml (3)
32-32: Label addition is well aligned!The deployment name label properly connects with the WorkloadMonitor selectors.
130-143: Control plane WorkloadMonitor configuration is solid!The monitor ensures high availability with:
- Minimum of 1 replica for basic operation
- Target of 2 replicas matching the KamajiControlPlane spec
276-289: Worker nodes WorkloadMonitor is properly configured!The monitor correctly:
- Uses group-specific minReplicas
- Implements precise label selection
- Includes version tracking
Let's verify the label consistency:
✅ Verification successful
Label selectors are consistent across the cluster configuration
The WorkloadMonitor's selector labels are properly aligned with the labels used throughout the cluster configuration:
cluster.x-k8s.io/cluster-name: Consistently uses Release.Namecluster.x-k8s.io/deployment-name: Correctly includes group namecluster.x-k8s.io/role: worker: Properly differentiates worker nodes🏁 Scripts executed

117-129: LGTM! WorkloadMonitor configuration aligns with Grafana deployment.The WorkloadMonitor configuration correctly matches the Grafana deployment's replica count and selector labels.
Consider adding topology spread constraints for high availability.
For better high availability, consider adding topology spread constraints to ensure replicas are distributed across different nodes.
spec: replicas: 2 minReplicas: 1 kind: monitoring type: grafana selector: app: grafana + topologySpreadConstraints: + - maxSkew: 1 + topologyKey: kubernetes.io/hostname + whenUnsatisfiable: DoNotSchedule + labelSelector: + matchLabels: + app: grafana version: {{ $.Chart.Version }}packages/extra/monitoring/templates/alerta/alerta.yaml (1)
235-247: Consider adjusting Alertmanager minReplicas for smaller clusters.While having minReplicas=2 ensures high availability, it might be too restrictive for smaller clusters. Consider making it configurable through values:
spec: replicas: 3 - minReplicas: 2 + minReplicas: {{ .Values.alertmanager.minReplicas | default 2 }} kind: monitoring type: alertmanagerThis allows operators to adjust the minimum replica count based on their cluster size and requirements.

- Matching name and replica count
- Specific selector targeting CloudNativePG instances
- Appropriate monitoring type for PostgreSQL

1-19: LGTM! Well-scoped RBAC permissions.The Role follows security best practices by:
- Limiting to read-only operations
- Specifying exact resource names instead of wildcards
- Separating permissions by API group

11-11: Verify trimPrefix behavior for unexpected namespace names.The
trimPrefixfunction assumes namespace starts with "tenant-". This could fail silently for namespaces without this prefix.Consider adding validation or fallback:
- - {{ trimPrefix "tenant-" .Release.Namespace }}-ingress-controller + {{- $namespace := trimPrefix "tenant-" .Release.Namespace }} + {{- if eq $namespace .Release.Namespace }} + {{- fail "Expected namespace to start with 'tenant-'" }} + {{- end }} + - {{ $namespace }}-ingress-controllerpackages/extra/ingress/templates/workloadmonitor.yaml (2)
12-15: LGTM! Well-structured selector.The selector effectively targets ingress-nginx pods using multiple labels, following Kubernetes best practices for reliable pod selection.
8-9: Verify minReplicas calculation for edge cases.The formula
{{ div .Values.replicas 2 | add1 }}works well for most cases but consider:
- When replicas=1, minReplicas=1 (potential single point of failure)
- When replicas=2, minReplicas=2 (no degraded mode possible)
Consider adjusting the formula or adding validation:
- minReplicas: {{ div .Values.replicas 2 | add1 }} + {{- $minReplicas := div .Values.replicas 2 | add1 }} + {{- if eq .Values.replicas 2 }} + {{- $minReplicas = 1 }} + {{- end }} + minReplicas: {{ $minReplicas }}packages/extra/seaweedfs/templates/dashboard-resourcemap.yaml (1)
1-29: LGTM! Comprehensive RBAC for SeaweedFS components.The Role effectively manages permissions for all SeaweedFS components (master, filer, volume, db) while maintaining the principle of least privilege.
