# Helm Deployment
|
||||
|
||||
Deploy the Headlamp Polaris Plugin using Helm charts.
|
||||
|
||||
## Overview
|
||||
|
||||
Helm provides the easiest way to deploy and manage the plugin in production. This guide covers:
|
||||
|
||||
- Helm values configuration
|
||||
- Plugin Manager integration
|
||||
- FluxCD HelmRelease integration
|
||||
- Upgrade procedures
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Helm v3+ installed
|
||||
- Kubernetes cluster access
|
||||
- Headlamp Helm repository added
|
||||
|
||||
```bash
|
||||
# Add Headlamp Helm repository
|
||||
helm repo add headlamp https://headlamp-k8s.github.io/headlamp/
|
||||
helm repo update
|
||||
```
|
||||
|
||||
## Basic Helm Installation
|
||||
|
||||
### Minimal Configuration
|
||||
|
||||
```yaml
|
||||
# headlamp-values.yaml
|
||||
config:
|
||||
pluginsDir: /headlamp/plugins
|
||||
watchPlugins: false # CRITICAL for v0.39.0+
|
||||
|
||||
pluginsManager:
|
||||
enabled: true
|
||||
repositories:
|
||||
- https://artifacthub.io/packages/search?kind=4
|
||||
```
|
||||
|
||||
```bash
|
||||
# Install Headlamp
|
||||
helm install headlamp headlamp/headlamp \
|
||||
--namespace kube-system \
|
||||
--values headlamp-values.yaml
|
||||
|
||||
# Wait for deployment
|
||||
kubectl -n kube-system wait --for=condition=available deployment/headlamp --timeout=300s
|
||||
```
|
||||
|
||||
After installation, install the plugin via Headlamp UI (**Settings → Plugins → Catalog**).
|
||||
|
||||
## Complete Production Configuration
|
||||
|
||||

```
|
||||
|
||||
Deploy:
|
||||
|
||||
```bash
|
||||
helm upgrade --install headlamp headlamp/headlamp \
|
||||
--namespace kube-system \
|
||||
--values headlamp-values.yaml \
|
||||
--wait \
|
||||
--timeout 5m
|
||||
```
|
||||
|
||||
## Sidecar Plugin Installation Method
|
||||
|
||||
Alternative to Plugin Manager: use an init container to download the plugin.
|
||||
|
||||
```yaml
|
||||
# headlamp-values.yaml
|
||||
config:
|
||||
pluginsDir: /headlamp/plugins
|
||||
watchPlugins: false
|
||||
|
||||
initContainers:
|
||||
- name: install-polaris-plugin
|
||||
image: node:lts-alpine
|
||||
command:
|
||||
- sh
|
||||
- -c
|
||||
- |
|
||||
npm install -g @kinvolk/headlamp-plugin
|
||||
headlamp-plugin install --config /config/plugin.yml --plugins-dir /plugins
|
||||
volumeMounts:
|
||||
- name: plugins
|
||||
mountPath: /plugins
|
||||
- name: plugin-config
|
||||
mountPath: /config
|
||||
|
||||
volumes:
|
||||
- name: plugins
|
||||
emptyDir: {}
|
||||
- name: plugin-config
|
||||
configMap:
|
||||
name: headlamp-plugin-config
|
||||
```
|
||||
|
||||
Create the ConfigMap:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: v1
|
||||
kind: ConfigMap
|
||||
metadata:
|
||||
name: headlamp-plugin-config
|
||||
namespace: kube-system
|
||||
data:
|
||||
plugin.yml: |
|
||||
- name: headlamp-polaris-plugin
|
||||
version: 0.3.5
|
||||
url: https://github.com/cpfarhood/headlamp-polaris-plugin/releases/download/v0.3.5/headlamp-polaris-plugin-0.3.5.tar.gz
|
||||
```
|
||||
|
||||
Apply ConfigMap then deploy Headlamp:
|
||||
|
||||
```bash
|
||||
kubectl apply -f headlamp-plugin-config.yaml
|
||||
|
||||
helm upgrade --install headlamp headlamp/headlamp \
|
||||
--namespace kube-system \
|
||||
--values headlamp-values.yaml
|
||||
```
|
||||
|
||||

# Watch deployment
|
||||
flux get helmreleases -n kube-system --watch
|
||||
```
|
||||
|
||||
## RBAC Configuration
|
||||
|
||||
After deploying Headlamp, apply RBAC for the plugin:
|
||||
|
||||
```bash
|
||||
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
|

|
||||
EOF
|
||||
```
|
||||
|
||||
See [RBAC Permissions](../user-guide/rbac-permissions.md) for advanced RBAC configurations.
|
||||
|
||||
## Upgrading
|
||||
|
||||
### Upgrade Headlamp
|
||||
|
||||
```bash
|
||||
# Update Helm repo
|
||||
helm repo update
|
||||
|
||||
# Upgrade Headlamp (preserves plugin configuration)
|
||||
helm upgrade headlamp headlamp/headlamp \
|
||||
--namespace kube-system \
|
||||
--values headlamp-values.yaml \
|
||||
--wait
|
||||
```
|
||||
|
||||
### Upgrade Plugin (Plugin Manager Method)
|
||||
|
||||
1. Navigate to **Settings → Plugins** in Headlamp UI
|
||||
2. Find "headlamp-polaris-plugin"
|
||||
3. Click **Update** if new version available
|
||||
4. Hard refresh browser (**Cmd+Shift+R** / **Ctrl+Shift+R**)
|
||||
|
||||
### Upgrade Plugin (Sidecar Method)
|
||||
|
||||
```bash
|
||||
# Update ConfigMap with new version
|
||||
kubectl -n kube-system edit configmap headlamp-plugin-config
|
||||
|
||||
# Update version and URL:
|
||||
# version: 0.3.6
|
||||
# url: https://github.com/.../v0.3.6/headlamp-polaris-plugin-0.3.6.tar.gz
|
||||
|
||||
# Restart deployment to trigger init container
|
||||
kubectl -n kube-system rollout restart deployment/headlamp
|
||||
kubectl -n kube-system rollout status deployment/headlamp
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Plugin Not Loading
|
||||
|
||||
```bash
|
||||
# Check Headlamp values
|
||||
helm get values headlamp -n kube-system
|
||||
|
||||
# Verify watchPlugins is false:
|
||||
# config:
|
||||
# watchPlugins: false
|
||||
|
||||
# If incorrect, update values and upgrade:
|
||||
helm upgrade headlamp headlamp/headlamp \
|
||||
--namespace kube-system \
|
||||
--values headlamp-values.yaml \
|
||||
--set config.watchPlugins=false
|
||||
```
|
||||
|
||||
### Helm Release Stuck
|
||||
|
||||
```bash
|
||||
# Check Helm release status
|
||||
helm list -n kube-system
|
||||
|
||||
# If stuck, force upgrade
|
||||
helm upgrade headlamp headlamp/headlamp \
|
||||
--namespace kube-system \
|
||||
--values headlamp-values.yaml \
|
||||
--force \
|
||||
--wait
|
||||
```
|
||||
|
||||
### FluxCD Reconciliation Issues
|
||||
|
||||
```bash
|
||||
# Check HelmRelease status
|
||||
flux get helmreleases -n kube-system
|
||||
|
||||
# Check events
|
||||
kubectl -n kube-system describe helmrelease headlamp
|
||||
|
||||
# Force reconciliation
|
||||
flux reconcile helmrelease headlamp -n kube-system
|
||||
```
|
||||
|
||||

# Kubernetes Deployment
|
||||
|
||||
Direct Kubernetes manifest deployment for the Headlamp Polaris Plugin.
|
||||
|
||||
## Overview
|
||||
|
||||
This guide covers deploying the plugin using raw Kubernetes manifests without Helm. This approach is useful for:
|
||||
|
||||
- Environments where Helm is not available
|
||||
- Highly customized deployments
|
||||
- GitOps workflows with Kustomize
|
||||
- Learning the underlying Kubernetes resources
|
||||
|
||||
## RBAC Manifests
|
||||
|
||||
The plugin requires read-only access to the Polaris dashboard service proxy.
|
||||
|
||||
### Complete RBAC Configuration
|
||||
|
||||
```yaml
|
||||
---
|
||||
# Role: Read-only access to Polaris service proxy
|
||||
apiVersion: rbac.authorization.k8s.io/v1
|
||||
kind: Role
|
||||
metadata:
|
||||
name: polaris-proxy-reader
|
||||
namespace: polaris
|
||||
labels:
|
||||
app.kubernetes.io/name: headlamp-polaris-plugin
|
||||
app.kubernetes.io/component: rbac
|
||||
rules:
|
||||
- apiGroups: [""]
|
||||
resources: ["services/proxy"]
|
||||
resourceNames: ["polaris-dashboard"]
|
||||
verbs: ["get"]
|
||||
|
||||
---
|
||||
# RoleBinding: Grant Headlamp service account access
|
||||
apiVersion: rbac.authorization.k8s.io/v1
|
||||
kind: RoleBinding
|
||||
metadata:
|
||||
name: headlamp-polaris-proxy
|
||||
namespace: polaris
|
||||
labels:
|
||||
app.kubernetes.io/name: headlamp-polaris-plugin
|
||||
app.kubernetes.io/component: rbac
|
||||
subjects:
|
||||
- kind: ServiceAccount
|
||||
name: headlamp
|
||||
namespace: kube-system
|
||||
roleRef:
|
||||
kind: Role
|
||||
name: polaris-proxy-reader
|
||||
apiGroup: rbac.authorization.k8s.io
|
||||
```
|
||||
|
||||
Apply the RBAC manifests:
|
||||
|
||||
```bash
|
||||
kubectl apply -f polaris-plugin-rbac.yaml
|
||||
```
|
||||
|
||||
### RBAC Verification
|
||||
|
||||
```bash
|
||||
# Verify Role exists
|
||||
kubectl -n polaris get role polaris-proxy-reader
|
||||
|
||||
# Verify RoleBinding exists
|
||||
kubectl -n polaris get rolebinding headlamp-polaris-proxy
|
||||
|
||||
# Test permission
|
||||
kubectl auth can-i get services/proxy \
|
||||
--as=system:serviceaccount:kube-system:headlamp \
|
||||
-n polaris \
|
||||
--resource-name=polaris-dashboard
|
||||
|
||||
# Expected output: yes
|
||||
```
|
||||
|
||||
## Plugin Installation via Init Container
|
||||
|
||||
Use an init container to download and install the plugin.
|
||||
|
||||
### ConfigMap for Plugin Configuration

## Complete Deployment Workflow
|
||||
|
||||
### 1. Apply All Manifests
|
||||
|
||||
```bash
|
||||
# Create RBAC for Polaris plugin
|
||||
kubectl apply -f polaris-plugin-rbac.yaml
|
||||
|
||||
# Create plugin configuration
|
||||
kubectl apply -f headlamp-plugin-config.yaml
|
||||
|
||||
# Deploy Headlamp with plugin init container
|
||||
kubectl apply -f headlamp-deployment.yaml
|
||||
kubectl apply -f headlamp-service.yaml
|
||||
kubectl apply -f headlamp-serviceaccount.yaml
|
||||
|
||||
# Wait for deployment to be ready
|
||||
kubectl -n kube-system wait --for=condition=available deployment/headlamp --timeout=300s
|
||||
```
|
||||
|
||||
### 2. Verify Deployment
|
||||
|
||||
```bash
|
||||
# Check pods are running
|
||||
kubectl -n kube-system get pods -l app.kubernetes.io/name=headlamp
|
||||
|
||||
# Expected output:
|
||||
# NAME READY STATUS RESTARTS AGE
|
||||
# headlamp-xxxxxxxxxx-xxxxx 1/1 Running 0 2m
|
||||
|
||||
# Check init container logs
|
||||
kubectl -n kube-system logs deployment/headlamp -c install-plugins
|
||||
|
||||
# Expected output:
|
||||
# Plugin installation complete
|
||||
|
||||
# Verify plugin files exist
|
||||
kubectl -n kube-system exec deployment/headlamp -c headlamp -- \
|
||||
ls -la /headlamp/plugins/headlamp-polaris-plugin/
|
||||
|
||||
# Expected output:
|
||||
# drwxr-xr-x dist/
|
||||
# -rw-r--r-- package.json
|
||||
|
||||
# Test Polaris API access
|
||||
kubectl get --raw /api/v1/namespaces/polaris/services/polaris-dashboard:80/proxy/results.json \
|
||||
| jq .PolarisOutputVersion
|
||||
|
||||
# Expected output: "1.0" or similar
|
||||
```
|
||||
|
||||
### 3. Access Headlamp
|
||||
|
||||
```bash
|
||||
# Port-forward to access locally
|
||||
kubectl -n kube-system port-forward service/headlamp 8080:80
|
||||
|
||||
# Open browser to http://localhost:8080
|
||||
```

|
||||
|
||||
## Upgrading the Plugin
|
||||
|
||||
### Update ConfigMap
|
||||
|
||||
```bash
|
||||
# Edit ConfigMap with new version
|
||||
kubectl -n kube-system edit configmap headlamp-plugin-config
|
||||
|
||||
# Update version and URL:
|
||||
# version: 0.3.6
|
||||
# url: https://github.com/.../v0.3.6/headlamp-polaris-plugin-0.3.6.tar.gz
|
||||
|
||||
# Restart deployment to trigger init container
|
||||
kubectl -n kube-system rollout restart deployment/headlamp
|
||||
|
||||
# Wait for rollout to complete
|
||||
kubectl -n kube-system rollout status deployment/headlamp
|
||||
```
|
||||
|
||||
### Verify Upgrade
|
||||
|
||||
```bash
|
||||
# Check init container logs
|
||||
kubectl -n kube-system logs deployment/headlamp -c install-plugins
|
||||
|
||||
# Verify new version in UI
|
||||
# Navigate to Settings → Plugins in Headlamp
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Init Container Fails
|
||||
|
||||
```bash
|
||||
# Check init container logs
|
||||
kubectl -n kube-system logs deployment/headlamp -c install-plugins
|
||||
|
||||
# Common issues:
|
||||
# 1. Network connectivity to GitHub
|
||||
# 2. Invalid URL in ConfigMap
|
||||
# 3. Tarball checksum mismatch
|
||||
```
|
||||
|
||||
### Plugin Not Loading
|
||||
|
||||
```bash
|
||||
# Verify HEADLAMP_CONFIG_WATCH_PLUGINS is false
|
||||
kubectl -n kube-system get deployment headlamp -o yaml | grep WATCH_PLUGINS
|
||||
|
||||
# Expected output:
|
||||
# - name: HEADLAMP_CONFIG_WATCH_PLUGINS
|
||||
# value: "false"
|
||||
|
||||
# If not set or "true", update deployment
|
||||
kubectl -n kube-system edit deployment headlamp
|
||||
```
|
||||
|
||||
### RBAC Permissions Denied
|
||||
|
||||
```bash
|
||||
# Test RBAC
|
||||
kubectl auth can-i get services/proxy \
|
||||
--as=system:serviceaccount:kube-system:headlamp \
|
||||
-n polaris \
|
||||
--resource-name=polaris-dashboard
|
||||
|
||||
# If "no", verify RBAC manifests applied:
|
||||
kubectl -n polaris get role polaris-proxy-reader
|
||||
kubectl -n polaris get rolebinding headlamp-polaris-proxy
|
||||
```
|
||||

|
||||
|
||||
### Post-Deployment Verification
|
||||
|
||||
```bash
|
||||
# 1. Verify Polaris API is accessible via service proxy
|
||||
kubectl get --raw /api/v1/namespaces/polaris/services/polaris-dashboard:80/proxy/results.json | jq .PolarisOutputVersion
|
||||
# Expected: "1.0" or similar
|
||||
|
||||
# 2. Verify RBAC permissions
|
||||
kubectl auth can-i get services/proxy \
|
||||
--as=system:serviceaccount:kube-system:headlamp \
|
||||
-n polaris \
|
||||
--resource-name=polaris-dashboard
|
||||
# Expected: yes
|
||||
|
||||
# 3. Check Headlamp logs for plugin loading
|
||||
kubectl -n kube-system logs deployment/headlamp | grep -i polaris
|
||||
# Expected: No errors related to plugin loading
|
||||
|
||||
# 4. Verify plugin files exist
|
||||
kubectl -n kube-system exec deployment/headlamp -c headlamp -- ls -la /headlamp/plugins/headlamp-polaris-plugin/

|
||||
- [ ] App bar shows Polaris score badge
|
||||
- [ ] Click namespace - detail drawer opens
|
||||
- [ ] Test inline audit section on a Deployment/StatefulSet
|
||||
|
||||
## Security Best Practices
|
||||
|
||||
### RBAC
|
||||
|
||||
**Principle of Least Privilege:**
|
||||
|
||||
```yaml
|
||||
# ✅ GOOD: Scoped to specific service
|
||||
rules:
|
||||
- apiGroups: [""]
|
||||
resources: ["services/proxy"]
|
||||
resourceNames: ["polaris-dashboard"]
|
||||
verbs: ["get"]
|
||||
|
||||
# ❌ BAD: Too broad
|
||||
rules:
|
||||
- apiGroups: [""]
|
||||
resources: ["services/proxy"]
|
||||
verbs: ["get"] # Allows proxy to ALL services
|
||||
```
|
||||
|
||||
**Token-Auth Mode:**
|
||||
|
||||
When Headlamp uses user-supplied tokens (OIDC), each user needs the RoleBinding:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: rbac.authorization.k8s.io/v1
|
||||
kind: RoleBinding
|
||||
metadata:
|
||||
name: authenticated-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
|
||||
```
|
||||
|
||||
For fine-grained control, bind specific users or groups:
|
||||
|
||||
```yaml
|
||||
subjects:
|
||||
- kind: Group
|
||||
name: sre-team # Only SRE team
|
||||
apiGroup: rbac.authorization.k8s.io
|
||||
```
|
||||
|
||||
### Network Policies
|
||||
|
||||
If using strict NetworkPolicies:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: networking.k8s.io/v1
|
||||
kind: NetworkPolicy
|
||||
metadata:
|
||||
name: allow-apiserver-to-polaris
|
||||
namespace: polaris
|
||||
spec:
|
||||
podSelector:
|
||||
matchLabels:
|
||||
app.kubernetes.io/name: polaris
|
||||
app.kubernetes.io/component: dashboard
|
||||
policyTypes:
|
||||
- Ingress
|
||||
ingress:
|
||||
# Allow from API server (performs the proxy hop)
|
||||
- from:
|
||||
- namespaceSelector:
|
||||
matchLabels:
|
||||
kubernetes.io/metadata.name: kube-system
|
||||
- podSelector:
|
||||
matchLabels:
|
||||
component: kube-apiserver
|
||||
ports:
|
||||
- protocol: TCP
|
||||
port: 80
|
||||
```
|
||||
|
||||
**Note:** The API server proxies the request, not the Headlamp pod directly.
|
||||
|
||||
### Audit Logging
|
||||
|
||||
Kubernetes audit logs record every service proxy request:
|
||||
|
||||
- **What's logged:** User/service account, timestamp, response code
|
||||
- **Volume:** Auto-refresh interval affects audit log volume
|
||||
- **Recommendation:** Configure audit policy level if concerned about log volume
|
||||
|
||||
```yaml
|
||||
# audit-policy.yaml
|
||||
apiVersion: audit.k8s.io/v1
|
||||
kind: Policy
|
||||
rules:

```
|
||||
|
||||
### Data Sensitivity
|
||||
|
||||
Polaris audit data may contain:
|
||||
|
||||
- Resource names and namespaces
|
||||
- Configuration details
|
||||
- Potential security vulnerabilities
|
||||
|
||||
**Recommendation:** Restrict plugin access to authorized users only (not `system:authenticated` unless appropriate).
|
||||
|
||||
## High Availability
|
||||
|
||||
### Headlamp Replicas
|
||||
|
||||
Deploy Headlamp with 2+ replicas for high availability:
|
||||
|
||||
```yaml
|
||||
# helm-values.yaml
|
||||
replicaCount: 2
|
||||
|
||||
affinity:
|
||||
podAntiAffinity:
|
||||
preferredDuringSchedulingIgnoredDuringExecution:
|
||||
- weight: 100
|
||||
podAffinityTerm:
|
||||
labelSelector:
|
||||
matchLabels:
|
||||
app.kubernetes.io/name: headlamp
|
||||
topologyKey: kubernetes.io/hostname
|
||||
|
||||
resources:
|
||||
limits:
|
||||
cpu: 500m
|
||||
memory: 512Mi
|
||||
requests:
|
||||
cpu: 100m
|
||||
memory: 128Mi
|
||||
```
|
||||
|
||||
### Pod Disruption Budget
|
||||
|
||||
Ensure at least one replica is always available during node maintenance:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: policy/v1
|
||||
kind: PodDisruptionBudget
|
||||
metadata:
|
||||
name: headlamp-pdb
|
||||
namespace: kube-system
|
||||
spec:
|
||||
minAvailable: 1
|
||||
selector:
|
||||
matchLabels:
|
||||
app.kubernetes.io/name: headlamp
|
||||
```
|
||||
|
||||
### Health Checks
|
||||
|
||||
Configure liveness and readiness probes:
|
||||
|
||||
```yaml
|
||||
livenessProbe:
|
||||
httpGet:
|
||||
path: /
|
||||
port: http
|
||||
initialDelaySeconds: 30
|
||||
periodSeconds: 10
|
||||
|
||||
readinessProbe:
|
||||
httpGet:
|
||||
path: /
|
||||
port: http
|
||||
initialDelaySeconds: 10
|
||||
periodSeconds: 5
|
||||
```
|
||||
|
||||
## Monitoring and Observability
|
||||
|
||||
### Metrics to Monitor
|
||||
|
||||
**Application Metrics:**
|
||||
|
||||
- Headlamp pod CPU/memory usage
|
||||
- HTTP request latency and error rates
|
||||
- Plugin load time
|
||||
|
||||
**Polaris Metrics:**
|
||||
|
||||
- Polaris dashboard API response time
|
||||
- Service proxy request latency
|
||||
- RBAC denial rate (403 errors)
|
||||
|
||||
### Prometheus Integration
|
||||
|
||||
Example ServiceMonitor for Headlamp:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: monitoring.coreos.com/v1
|
||||
kind: ServiceMonitor
|
||||
metadata:
|
||||
name: headlamp
|
||||
namespace: kube-system
|
||||
spec:
|
||||
selector:
|
||||
matchLabels:
|
||||
app.kubernetes.io/name: headlamp
|
||||
endpoints:
|
||||
- port: http
|
||||
interval: 30s
|
||||
path: /metrics
|
||||
```
|
||||
|
||||
### Logging
|
||||
|
||||
**Headlamp Logs:**
|
||||
|
||||
```bash
|
||||
# View logs
|
||||
kubectl -n kube-system logs deployment/headlamp -f
|
||||
|
||||
# Filter for plugin-related logs
|
||||
kubectl -n kube-system logs deployment/headlamp | grep -i polaris
|
||||
```
|
||||
|
||||
**Polaris Dashboard Logs:**
|
||||
|
||||
```bash
|
||||
kubectl -n polaris logs deployment/polaris-dashboard -f
|
||||
```
|
||||
|
||||
### Alerts
|
||||
|
||||
Recommended alerts:
|
||||
|
||||
- Headlamp pod not ready
|
||||
- High error rate (4xx/5xx)
|
||||
- Polaris dashboard unavailable
|
||||
- RBAC denials (403 errors)
|
||||
|
||||
Example PrometheusRule:
|
||||
|
||||
```yaml
|
||||
---
|
||||
apiVersion: monitoring.coreos.com/v1
|
||||
kind: PrometheusRule
|
||||
metadata:
|
||||
name: headlamp-alerts
|
||||
namespace: kube-system
|
||||
spec:
|
||||
groups:
|
||||
- name: headlamp
|
||||
interval: 30s
|
||||
rules:
|
||||
- alert: HeadlampPodNotReady
|
||||
expr: kube_pod_status_ready{namespace="kube-system", pod=~"headlamp-.*"} == 0
|
||||
for: 5m
|
||||
labels:
|
||||
severity: warning
|
||||
annotations:
|
||||
summary: "Headlamp pod not ready"
|
||||
description: "Pod {{ $labels.pod }} in namespace {{ $labels.namespace }} has been not ready for 5 minutes."
|
||||
```
|
||||
|
||||
## Performance Tuning
|
||||
|
||||
### Plugin Refresh Interval
|
||||
|
||||
The plugin auto-refreshes Polaris data at a configurable interval (default: 5 minutes).
|
||||
|
||||
**Recommendations:**
|
||||
|
||||
- **High-traffic clusters:** 10-30 minutes (reduces API server load)
|
||||
- **Low-traffic clusters:** 1-5 minutes (more real-time data)
|
||||
|
||||
Configure via **Settings → Plugins → Polaris** in Headlamp UI.
|
||||
|
||||
### Browser Caching
|
||||
|
||||
The plugin uses localStorage for settings. Browser cache can affect plugin loading.
|
||||
|
||||
**Best Practice:** Instruct users to hard refresh after plugin updates (**Cmd+Shift+R** / **Ctrl+Shift+R**).
|
||||
|
||||
### Resource Limits
|
||||
|
||||
Recommended resource limits for Headlamp with plugin:
|
||||
|
||||
```yaml
|
||||
resources:
|
||||
limits:
|
||||
cpu: 500m
|
||||
memory: 512Mi
|
||||
requests:
|
||||
cpu: 100m
|
||||
memory: 128Mi
|
||||
```
|
||||
|
||||
Adjust based on cluster size and user count.
|
||||
|
||||
## Disaster Recovery
|
||||
|
||||
### Backup Considerations
|
||||
|
||||
**What to back up:**
|
||||
|
||||
- Headlamp Helm values or Kubernetes manifests
|
||||
- RBAC manifests (Role, RoleBinding)
|
||||
- Plugin configuration (ConfigMap if using sidecar method)
|
||||
|
||||
**What NOT to back up:**
|
||||
|
||||
- Plugin tarball (available on GitHub releases)
|
||||
- Polaris audit data (regenerated by Polaris)
|
||||
- Browser localStorage (user-specific settings)
|
||||
|
||||
### Recovery Procedure
|
||||
|
||||
If Headlamp or plugin becomes unavailable:
|
||||
|
||||
1. **Verify Polaris is running:**
|
||||
```bash
|
||||
kubectl -n polaris get pods
|
||||
kubectl -n polaris get svc polaris-dashboard
|
||||
```
|
||||
|
||||
2. **Redeploy Headlamp:**
|
||||
```bash
|
||||
helm upgrade --install headlamp headlamp/headlamp \
|
||||
--namespace kube-system \
|
||||
--values headlamp-values.yaml
|
||||
```
|
||||
|
||||
3. **Reapply RBAC:**
|
||||
```bash
|
||||
kubectl apply -f polaris-plugin-rbac.yaml
|
||||
```
|
||||
|
||||
4. **Verify plugin files:**
|
||||
```bash
|
||||
kubectl -n kube-system exec deployment/headlamp -- \
|
||||
ls /headlamp/plugins/headlamp-polaris-plugin/
|
||||
```
|
||||
|
||||
5. **Hard refresh browser:**
|
||||
**Cmd+Shift+R** / **Ctrl+Shift+R**
|
||||
|
||||
## Known Issues
|
||||
|
||||
### Plugin Loading Issue (Headlamp v0.39.0+)
|
||||
|
||||
**Symptom:** Plugin appears in Settings but not in sidebar
|
||||
|
||||
**Cause:** `config.watchPlugins: true` (default) treats catalog plugins as development plugins
|
||||
|
||||
**Fix:**
|
||||
|
||||
```yaml
|
||||
config:
|
||||
watchPlugins: false # Required for plugin manager
|
||||
```
|
||||
|
||||
**Root Cause:**
|
||||
|
||||
With `watchPlugins: true`, Headlamp backend serves plugin metadata but frontend never executes the JavaScript. This causes plugins to appear in Settings but no sidebar/routes/settings work.
|
||||
|
||||
**Documentation:** See `deployment/PLUGIN_LOADING_FIX.md` in repository for full analysis.
|
||||
|
||||
**After Fix:**
|
||||
|
||||
- Restart Headlamp deployment
|
||||
- Hard refresh browser (**Cmd+Shift+R** / **Ctrl+Shift+R**)
|
||||
|
||||
### Skipped Count Limitation
|
||||
|
||||
**Symptom:** "Skipped" count in UI is lower than native Polaris dashboard
|
||||
|
||||
**Cause:** Plugin only counts checks with `Severity: "ignore"` from API response
|
||||
|
||||
**Explanation:**
|
||||
|
||||
Polaris omits annotation-based exemptions (e.g., `polaris.fairwinds.com/*-exempt`) from the `results.json` endpoint. The native Polaris dashboard computes skipped count by querying raw Kubernetes resources and parsing annotations.
|
||||
|
||||
**Workaround:** Use "View in Polaris Dashboard" link for accurate exemption count.
|
||||
|
||||
**Future Enhancement:** Would require cluster-wide read access to all workload types (significant RBAC expansion).
|
||||
|
||||
### ArtifactHub Sync Delay
|
||||
|
||||
**Symptom:** New plugin version not appearing in Headlamp catalog
|
||||
|
||||
**Cause:** ArtifactHub syncs from GitHub every 30 minutes (no webhook/push mechanism)
|
||||
|
||||
**Solution:** Wait 30 minutes after GitHub release for new version to appear in catalog.

||||
