## Prerequisites
|
||||
|
||||
Before installation, ensure all [prerequisites](prerequisites.md) are met:
|
||||
|
||||
- Kubernetes v1.24+
|
||||
- Headlamp v0.26+ (v0.39+ recommended)
|
||||
- Polaris deployed with dashboard enabled
|
||||
- RBAC permissions configured
|
||||
|
||||
## Installation Methods
|
||||
|
||||
### Option 1: Plugin Manager (Recommended)
|
||||
|
||||
**Best for:** Production deployments, managed updates, ease of use
|
||||
|
||||
The plugin is published on [Artifact Hub](https://artifacthub.io/packages/headlamp/polaris/headlamp-polaris-plugin) and can be installed via the Headlamp Plugin Manager.
|
||||
|
||||
#### Via Headlamp UI
|
||||
|
||||
1. **Navigate to Plugin Settings:**
|
||||
- Open Headlamp in your browser
|
||||
- Go to **Settings → Plugins**
|
||||
- Click the **Catalog** tab
|
||||
|
||||
2. **Search and Install:**
|
||||
- Search for "Polaris"
|
||||
- Find "Headlamp Polaris Plugin"
|
||||
- Click **Install**
|
||||
|
||||
3. **Hard Refresh Browser:**
|
||||
- **Mac:** Cmd+Shift+R
|
||||
- **Windows/Linux:** Ctrl+Shift+R
|
||||
|
||||
4. **Verify Installation:**
|
||||
- Sidebar should show "Polaris" entry
|
||||
- Click **Polaris** → Overview page loads
|
||||
|
||||
#### Via Helm Configuration
|
||||
|
||||
Add to your Headlamp Helm values:
|
||||
|
||||
```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
|
||||
```
|
||||
|
||||
Deploy or update Headlamp:
|
||||
|
||||
```bash
|
||||
helm upgrade --install headlamp headlamp/headlamp \
|
||||
--namespace kube-system \
|
||||
--values headlamp-values.yaml
|
||||
```
|
||||
|
||||
Then install the plugin via Headlamp UI as described above.
|
||||
|
||||
#### Critical Configuration for Headlamp v0.39.0+
|
||||
|
||||
**⚠️ IMPORTANT:** You **must** set `config.watchPlugins: false` or the plugin will not load.
|
||||
|
||||
**Why?**
|
||||
- With `watchPlugins: true` (default), catalog-managed plugins are treated as "development directory" plugins
|
||||
- This causes the backend to serve metadata but the frontend never executes the JavaScript
|
||||
- Result: Plugin appears in Settings but no sidebar/routes/settings work
|
||||
|
||||
**Fix:**
|
||||
```yaml
|
||||
config:
|
||||
watchPlugins: false # Required for plugin manager
|
||||
```
|
||||
|
||||
See [deployment/PLUGIN_LOADING_FIX.md](../deployment/production.md#plugin-loading-issue-headlamp-v0390) for full root cause analysis.
|
||||
|
||||
### Option 2: Sidecar Container
|
||||
|
||||
**Best for:** Controlled plugin versions, air-gapped environments, specific version pinning
|
||||
|
||||
This method uses an init container to download and install the plugin from a tarball URL.
|
||||
|
||||
#### Helm Values Configuration
|
||||
|
||||
```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
|
||||
```
|
||||
|
||||
#### Plugin Configuration 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 Configuration
|
||||
|
||||
```bash
|
||||
# Create ConfigMap
|
||||
kubectl apply -f headlamp-plugin-config.yaml
|
||||
|
||||
# Deploy/update Headlamp with sidecar
|
||||
helm upgrade --install headlamp headlamp/headlamp \
|
||||
--namespace kube-system \
|
||||
--values headlamp-values.yaml
|
||||
|
||||
# Wait for pod to be ready
|
||||
kubectl -n kube-system wait --for=condition=ready pod -l app.kubernetes.io/name=headlamp --timeout=300s
|
||||
|
||||
# Verify plugin files
|
||||
kubectl -n kube-system exec -it deployment/headlamp -c headlamp -- ls -la /headlamp/plugins/headlamp-polaris-plugin/
|
||||
|
||||
# Expected output:
|
||||
# drwxr-xr-x dist/
|
||||
# -rw-r--r-- package.json
|
||||
```
|
||||
|
||||
### Option 3: Manual Tarball
|
||||
|
||||
**Best for:** Testing specific versions, offline installations
|
||||
|
||||
Download the plugin tarball and extract it into Headlamp's plugin directory.
|
||||
|
||||
#### Download and Extract
|
||||
|
||||
```bash
|
||||
# Download latest release
|
||||
VERSION=0.3.5
|
||||
wget https://github.com/cpfarhood/headlamp-polaris-plugin/releases/download/v${VERSION}/headlamp-polaris-plugin-${VERSION}.tar.gz
|
||||
|
||||
# Extract to plugin directory
|
||||
tar xzf headlamp-polaris-plugin-${VERSION}.tar.gz -C /headlamp/plugins/
|
||||
|
||||
# Verify extraction
|
||||
ls -la /headlamp/plugins/headlamp-polaris-plugin/
|
||||
|
||||
# Expected output:
|
||||
# drwxr-xr-x dist/
|
||||
# -rw-r--r-- package.json
|
||||
```
|
||||
|
||||
#### Kubernetes Volume Mount
|
||||
|
||||
If Headlamp runs in Kubernetes, mount the plugin directory as a volume:
|
||||
|
||||
```yaml
|
||||
# headlamp-values.yaml
|
||||
config:
|
||||
pluginsDir: /plugins
|
||||
|
||||
volumes:
|
||||
- name: plugins
|
||||
hostPath:
|
||||
path: /path/to/plugins # Where you extracted the tarball
|
||||
type: Directory
|
||||
|
||||
volumeMounts:
|
||||
- name: plugins
|
||||
mountPath: /plugins
|
||||
readOnly: true
|
||||
```
|
||||
|
||||
**Note:** This method is not recommended for production (hostPath is node-specific).
|
||||
|
||||
### Option 4: Build from Source
|
||||
|
||||
**Best for:** Development, contributing, testing unreleased features
|
||||
|
||||
Clone the repository and build the plugin from source.
|
||||
|
||||
#### Clone and Build
|
||||
|
||||
```bash
|
||||
# Clone repository
|
||||
git clone https://github.com/cpfarhood/headlamp-polaris-plugin.git
|
||||
cd headlamp-polaris-plugin
|
||||
|
||||
# Install dependencies
|
||||
npm install
|
||||
|
||||
# Build plugin
|
||||
npm run build
|
||||
|
||||
# Package tarball (optional)
|
||||
npm run package
|
||||
|
||||
# Extract to Headlamp plugin directory
|
||||
npx @kinvolk/headlamp-plugin extract . /headlamp/plugins
|
||||
```
|
||||
|
||||
#### Development Mode (Hot Reload)
|
||||
|
||||
For active development with hot reload:
|
||||
|
||||
```bash
|
||||
# Start Headlamp with plugin hot reload
|
||||
npm start
|
||||
|
||||
# Opens Headlamp at http://localhost:4466
|
||||
# Changes to src/ automatically rebuild and reload
|
||||
```
|
||||
|
||||
See [Development Workflow](../development/workflow.md) for detailed development setup.
|
||||
|
||||
## Post-Installation
|
||||
|
||||
After installing the plugin via any method:
|
||||
|
||||
### 1. Configure RBAC
|
||||
|
||||
Apply RBAC permissions for the plugin to access Polaris:
|
||||
|
||||
```bash
|
||||
# Create polaris-plugin-rbac.yaml
|
||||
cat <<EOF | kubectl apply -f -
|
||||
---
|
||||
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
|
||||
```
|
||||
|
||||
See [RBAC Permissions](../user-guide/rbac-permissions.md) for detailed RBAC configuration.
|
||||
|
||||
### 2. Restart Headlamp (if needed)
|
||||
|
||||
```bash
|
||||
# If you updated Helm values or ConfigMaps
|
||||
kubectl -n kube-system rollout restart deployment/headlamp
|
||||
|
||||
# Wait for pod to be ready
|
||||
kubectl -n kube-system wait --for=condition=ready pod -l app.kubernetes.io/name=headlamp --timeout=300s
|
||||
```
|
||||
|
||||
### 3. Clear Browser Cache
|
||||
|
||||
**Critical:** Hard refresh your browser to load the new plugin JavaScript:
|
||||
|
||||
- **Mac:** Cmd+Shift+R
|
||||
- **Windows/Linux:** Ctrl+Shift+R
|
||||
|
||||
### 4. Verify Installation
|
||||
|
||||
**UI Verification:**
|
||||
1. Navigate to **Settings → Plugins**
|
||||
2. Verify "headlamp-polaris-plugin" is listed
|
||||
3. Check version matches installed version
|
||||
4. Verify **Polaris** appears in sidebar
|
||||
5. Click **Polaris** → Overview page loads
|
||||
6. Cluster score displays correctly
|
||||
|
||||
**CLI Verification:**
|
||||
|
||||
```bash
|
||||
# Verify plugin files exist
|
||||
kubectl -n kube-system exec -it deployment/headlamp -c headlamp -- ls -la /headlamp/plugins/headlamp-polaris-plugin/
|
||||
|
||||
# Expected output:
|
||||
# drwxr-xr-x dist/
|
||||
# -rw-r--r-- package.json
|
||||
|
||||
# Check Headlamp logs for errors
|
||||
kubectl -n kube-system logs deployment/headlamp | grep -i polaris
|
||||
|
||||
# Expected: No errors related to plugin loading
|
||||
|
||||
# Test Polaris API access
|
||||
kubectl get --raw /api/v1/namespaces/polaris/services/polaris-dashboard:80/proxy/results.json | jq .PolarisOutputVersion
|
||||
|
||||
# Expected: "1.0" or similar
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Plugin Not in Sidebar
|
||||
|
||||
**Symptom:** Plugin listed in Settings → Plugins but no "Polaris" entry in sidebar
|
||||
|
||||
**Causes:**
|
||||
1. `watchPlugins: true` (should be `false` for v0.39.0+)
|
||||
2. Browser cache not cleared
|
||||
3. Plugin JavaScript failed to load
|
||||
|
||||
**Solution:**
|
||||
|
||||
```bash
|
||||
# 1. Check Headlamp config
|
||||
kubectl -n kube-system get configmap headlamp -o yaml | grep watchPlugins
|
||||
|
||||
# If "true" or missing, fix it:
|
||||
kubectl -n kube-system edit configmap headlamp
|
||||
# Set: watchPlugins: "false"
|
||||
|
||||
# 2. Restart Headlamp
|
||||
kubectl -n kube-system rollout restart deployment/headlamp
|
||||
|
||||
# 3. Hard refresh browser (Cmd+Shift+R or Ctrl+Shift+R)
|
||||
|
||||
# 4. Check browser console for JavaScript errors
|
||||
# Open DevTools → Console tab
|
||||
```
|
||||
|
||||
### 403 Forbidden Error
|
||||
|
||||
**Symptom:** Error loading Polaris data, 403 in browser console
|
||||
|
||||
**Cause:** RBAC permissions missing or incorrect
|
||||
|
||||
**Solution:**
|
||||
|
||||
See [RBAC Issues](../troubleshooting/rbac-issues.md) for detailed debugging.
|
||||
|
||||
### 404 Not Found Error
|
||||
|
||||
**Symptom:** Error loading Polaris data, 404 in browser console
|
||||
|
||||
**Causes:**
|
||||
1. Polaris not deployed
|
||||
2. Polaris service name incorrect
|
||||
3. Polaris namespace incorrect
|
||||
|
||||
**Solution:**
|
||||
|
||||
```bash
|
||||
# Verify Polaris deployment
|
||||
kubectl -n polaris get pods
|
||||
kubectl -n polaris get svc polaris-dashboard
|
||||
|
||||
# If service doesn't exist, install Polaris:
|
||||
helm install polaris fairwinds-stable/polaris \
|
||||
--namespace polaris \
|
||||
--create-namespace \
|
||||
--set dashboard.enabled=true
|
||||
```
|
||||
|
||||
### Plugin Version Mismatch
|
||||
|
||||
**Symptom:** Settings shows old version, ArtifactHub shows new version
|
||||
|
||||
**Cause:** ArtifactHub sync delay (30 minutes) or plugin manager cache
|
||||
|
||||
**Solution:**
|
||||
|
||||
```bash
|
||||
# Wait 30 minutes for ArtifactHub sync
|
||||
# Or manually force Headlamp restart:
|
||||
kubectl -n kube-system rollout restart deployment/headlamp
|
||||
```

|
||||
helm install polaris fairwinds-stable/polaris \
|
||||
--namespace polaris \
|
||||
--create-namespace \
|
||||
--set dashboard.enabled=true
|
||||
|
||||
# Wait for pods to be ready
|
||||
kubectl -n polaris wait --for=condition=ready pod -l app.kubernetes.io/name=polaris --timeout=300s
|
||||
```
|
||||
|
||||
## Headlamp Requirements
|
||||
|
||||
### Verify Headlamp Installation
|
||||
|
||||
```bash
|
||||
# Check Headlamp is deployed
|
||||
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 1h
|
||||
|
||||
# Check Headlamp version (must be v0.26+)
|
||||
kubectl -n kube-system get deployment headlamp -o jsonpath='{.spec.template.spec.containers[0].image}'
|
||||
|
||||
# Expected output:
|
||||
# ghcr.io/headlamp-k8s/headlamp:v0.39.0 (or similar)
|
||||
```
|
||||
|
||||
### Install Headlamp (if not present)
|
||||
|
||||
```bash
|
||||
# Add Headlamp Helm repository
|
||||
helm repo add headlamp https://headlamp-k8s.github.io/headlamp/
|
||||
helm repo update
|
||||
|
||||
# Install Headlamp
|
||||
helm install headlamp headlamp/headlamp \
|
||||
--namespace kube-system \
|
||||
--set config.pluginsDir="/headlamp/plugins" \
|
||||
--set config.watchPlugins=false \
|
||||
--set pluginsManager.enabled=true
|
||||
|
||||
# Wait for pod to be ready
|
||||
kubectl -n kube-system wait --for=condition=ready pod -l app.kubernetes.io/name=headlamp --timeout=300s
|
||||
```
|
||||
|
||||
## RBAC Requirements
|
||||
|
||||
The plugin requires permissions to access the Polaris dashboard via Kubernetes service proxy.
|
||||
|
||||
### Required Permission
|
||||
|
||||
| Verb | API Group | Resource | Resource Name | Namespace |
|
||||
| ----- | ----------- | ---------------- | ------------------- | --------- |
|
||||
| `get` | `""` (core) | `services/proxy` | `polaris-dashboard` | `polaris` |
|
||||
|
||||
### Verify RBAC Permissions
|
||||
|
||||
```bash
|
||||
# Test if Headlamp service account has permission
|
||||
kubectl auth can-i get services/proxy \
|
||||
--as=system:serviceaccount:kube-system:headlamp \
|
||||
-n polaris \
|
||||
--resource-name=polaris-dashboard
|
||||
|
||||
# Expected output: yes
|
||||
|
||||
# If "no", you need to create RBAC (see installation guide)
|
||||
```
|
||||
|
||||
## Network Requirements
|
||||
|
||||
### Service Proxy Access
|
||||
|
||||
The plugin accesses Polaris through the Kubernetes API server's service proxy:
|
||||
|
||||
```
|
||||
Headlamp Pod → Kubernetes API Server → Polaris Dashboard Service
|
||||
```
|
||||
|
||||
**Required network paths:**
|
||||
- Headlamp pod → Kubernetes API server (443)
|
||||
- Kubernetes API server → Polaris dashboard service (80)
|
||||
|
||||
### NetworkPolicy Considerations
|
||||
|
||||
If the `polaris` namespace has NetworkPolicies enabled, ensure the Kubernetes API server can reach the `polaris-dashboard` service on port 80.
|
||||
|
||||
### Test Network Connectivity
|
||||
|
||||
```bash
|
||||
# Test service proxy endpoint from API server
|
||||
kubectl get --raw /api/v1/namespaces/polaris/services/polaris-dashboard:80/proxy/results.json | jq . > /dev/null
|
||||
|
||||
# If successful, no output
|
||||
# If failed, check NetworkPolicies and service status
|
||||
```
|
||||
|
||||
## Browser Requirements
|
||||
|
||||
The plugin uses modern JavaScript features and requires:
|
||||
|
||||
- **ES2020+ support**
|
||||
- **localStorage** enabled
|
||||
- **JavaScript** enabled
|
||||
- **Cookies** enabled (for Headlamp session)
|
||||
|
||||
### Tested Browsers
|
||||
|
||||
| Browser | Minimum Version |
|
||||
| ---------------- | --------------- |
|
||||
| Chrome/Chromium | 80+ |
|
||||
| Firefox | 75+ |
|
||||
| Safari | 13.1+ |
|
||||
| Edge | 80+ |
|
||||
|
||||
## Optional Components
|
||||
|
||||
### OIDC Authentication (for multi-user deployments)
|
||||
|
||||
If using Headlamp with OIDC authentication, each user must have RBAC permissions for service proxy access (see [RBAC Permissions](../user-guide/rbac-permissions.md)).
|
||||
|
||||
### Ingress (for external access)
|
||||
|
||||
If exposing Headlamp externally, configure an Ingress with TLS:
|
||||
|
||||
```yaml
|
||||
ingress:
|
||||
enabled: true
|
||||
className: nginx
|
||||
annotations:
|
||||
cert-manager.io/cluster-issuer: letsencrypt-prod
|
||||
hosts:
|
||||
- host: headlamp.example.com
|
||||
paths:
|
||||
- path: /
|
||||
pathType: Prefix
|
||||
tls:
|
||||
- secretName: headlamp-tls
|
||||
hosts:
|
||||
- headlamp.example.com
|
||||
```
|
||||
|
||||
