RBAC Issues
Troubleshooting RBAC permissions and 403 errors for the Headlamp Polaris Plugin.
Overview
The plugin requires get permission on services/proxy resource for the polaris-dashboard service in the polaris namespace. Without this permission, you'll see 403 Forbidden errors.
Common Scenarios
403 Forbidden Error
Symptom: Error loading Polaris data, "Access denied (403)" in UI
Cause: Missing or incorrect RBAC binding
Solution:
# 1. Verify RBAC resources exist
kubectl -n polaris get role polaris-proxy-reader
kubectl -n polaris get rolebinding headlamp-polaris-proxy
# If missing, apply RBAC:
kubectl apply -f - <<EOF
---
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
name: polaris-proxy-reader
namespace: polaris
rules:
- apiGroups: [""]
resources: ["services/proxy"]
resourceNames: ["polaris-dashboard"]
verbs: ["get"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
name: headlamp-polaris-proxy
namespace: polaris
subjects:
- kind: ServiceAccount
name: headlamp
namespace: kube-system
roleRef:
kind: Role
name: polaris-proxy-reader
apiGroup: rbac.authorization.k8s.io
EOF
Token-Auth Mode
Symptom: 403 error when using Headlamp with user-supplied tokens
Cause: User's own identity lacks the RoleBinding
Solution:
Bind the Role to authenticated users or specific users/groups:
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
name: users-polaris-proxy
namespace: polaris
subjects:
- kind: Group
name: system:authenticated # All authenticated users
apiGroup: rbac.authorization.k8s.io
roleRef:
kind: Role
name: polaris-proxy-reader
apiGroup: rbac.authorization.k8s.io
Testing Permissions
# Test service account (in-cluster mode)
kubectl auth can-i get services/proxy \
--as=system:serviceaccount:kube-system:headlamp \
-n polaris \
--resource-name=polaris-dashboard
# Test user (token-auth mode)
kubectl auth can-i get services/proxy \
--as=user@example.com \
-n polaris \
--resource-name=polaris-dashboard
# Expected output: yes
