Remove all references to the incorrect `config.watchPlugins: false` requirement that was believed necessary for Headlamp v0.39.0+. Investigation revealed that plugins work correctly with the default `watchPlugins: true` setting. The earlier documentation was based on a misunderstanding of the plugin loading mechanism. Changes: - Remove watchPlugins: false from all YAML configuration examples - Remove warning sections about watchPlugins requirement - Update troubleshooting guides to focus on actual issues - Simplify installation instructions by removing unnecessary config Files updated: - README.md (main installation docs and troubleshooting table) - docs/DEPLOYMENT.md - docs/TROUBLESHOOTING.md - docs/getting-started/* (quick-start, installation, prerequisites) - docs/deployment/* (helm, production) - docs/troubleshooting/* (common-issues, README) - Multiple other doc files formatted by prettier This cleanup ensures ArtifactHub and GitHub documentation show correct, simplified installation instructions.

# 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:**
|
|
|
|
```bash
|
|
# 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:
|
|
|
|
```yaml
|
|
---
|
|
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
|
|
|
|
```bash
|
|
# 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
|
|
```
|
|
|
