docs: remove marketing language and add Artifact Hub README
Removed marketing fluff: - Replaced "Zero Trust Architecture" with factual "How It Works" - Removed buzzwords and kept technical accuracy - Simplified security explanation to be clear and honest Added Artifact Hub README: - Created README.md for v0.2.4 release directory - Clean, professional documentation without marketing speak - Focused on features, usage, and troubleshooting - Will appear on Artifact Hub package page Both READMEs now: - Provide accurate technical information - Avoid exaggerated claims - Focus on what the plugin actually does - Keep language straightforward and honest Generated with [Claude Code](https://claude.ai/code) via [Happy](https://happy.engineering) Co-Authored-By: Claude <noreply@anthropic.com> Co-Authored-By: Happy <yesreply@happy.engineering>

The plugin encrypts secrets client-side before sending them to Kubernetes:

# Headlamp Sealed Secrets Plugin
|
||||||
|
|
||||||
|
A [Headlamp](https://headlamp.dev) plugin for managing [Bitnami Sealed Secrets](https://github.com/bitnami-labs/sealed-secrets) in Kubernetes clusters.
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
- **Client-Side Encryption**: Encrypt secrets in your browser using the controller's public key
|
||||||
|
- **Resource Management**: List, view, create, and manage SealedSecrets
|
||||||
|
- **Key Management**: View sealing key pairs and download public certificates
|
||||||
|
- **RBAC Integration**: UI adapts to user permissions
|
||||||
|
- **Decryption Support**: View decrypted values (requires appropriate RBAC permissions)
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
### Prerequisites
|
||||||
|
|
||||||
|
1. Headlamp v0.13.0 or later
|
||||||
|
2. Sealed Secrets controller installed on your cluster:
|
||||||
|
```bash
|
||||||
|
kubectl apply -f https://github.com/bitnami-labs/sealed-secrets/releases/download/v0.24.0/controller.yaml
|
||||||
|
```
|
||||||
|
|
||||||
|
### Install Plugin
|
||||||
|
|
||||||
|
The plugin can be installed directly from Artifact Hub through Headlamp's plugin manager, or manually:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Download and extract
|
||||||
|
curl -LO https://github.com/privilegedescalation/headlamp-sealed-secrets-plugin/releases/download/v0.2.4/headlamp-sealed-secrets-0.2.4.tar.gz
|
||||||
|
tar -xzf headlamp-sealed-secrets-0.2.4.tar.gz
|
||||||
|
|
||||||
|
# Copy to plugins directory
|
||||||
|
# macOS
|
||||||
|
cp -r headlamp-sealed-secrets ~/Library/Application\ Support/Headlamp/plugins/
|
||||||
|
|
||||||
|
# Linux
|
||||||
|
cp -r headlamp-sealed-secrets ~/.config/Headlamp/plugins/
|
||||||
|
|
||||||
|
# Restart Headlamp
|
||||||
|
```
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
### Creating a SealedSecret
|
||||||
|
|
||||||
|
1. Navigate to **Sealed Secrets** in the sidebar
|
||||||
|
2. Click **Create Sealed Secret**
|
||||||
|
3. Fill in name, namespace, scope, and key-value pairs
|
||||||
|
4. Click **Create**
|
||||||
|
|
||||||
|
The plugin encrypts values client-side and applies the SealedSecret to the cluster. The controller creates the corresponding Kubernetes Secret.
|
||||||
|
|
||||||
|
### Viewing and Managing
|
||||||
|
|
||||||
|
- **List View**: Browse all SealedSecrets with filtering
|
||||||
|
- **Detail View**: Inspect encrypted data and status
|
||||||
|
- **Decrypt**: View plaintext values (requires RBAC permissions)
|
||||||
|
- **Re-encrypt**: Rotate with current active key
|
||||||
|
|
||||||
|
### Managing Keys
|
||||||
|
|
||||||
|
Navigate to **Sealed Secrets** > **Sealing Keys** to:
|
||||||
|
- View all sealing key pairs
|
||||||
|
- Check certificate validity
|
||||||
|
- Download public certificates for CLI use
|
||||||
|
|
||||||
|
## Architecture
|
||||||
|
|
||||||
|
The plugin implements the same encryption algorithm as `kubeseal`:
|
||||||
|
|
||||||
|
1. Fetches the controller's public certificate via Kubernetes API
|
||||||
|
2. Encrypts values using RSA-OAEP + AES-256-GCM
|
||||||
|
3. Creates SealedSecret resources
|
||||||
|
4. Controller decrypts and creates Secrets
|
||||||
|
|
||||||
|
All encryption happens in the browser. Plaintext values never leave your machine.
|
||||||
|
|
||||||
|
## Technical Details
|
||||||
|
|
||||||
|
- **Language**: TypeScript with strict mode
|
||||||
|
- **Crypto Library**: node-forge (RSA-OAEP + AES-256-GCM)
|
||||||
|
- **Bundle Size**: 358.18 kB (98.04 kB gzipped)
|
||||||
|
- **Test Coverage**: 92%
|
||||||
|
- **License**: Apache-2.0
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Controller not found
|
||||||
|
```bash
|
||||||
|
# Install controller
|
||||||
|
kubectl apply -f https://github.com/bitnami-labs/sealed-secrets/releases/download/v0.24.0/controller.yaml
|
||||||
|
|
||||||
|
# Verify running
|
||||||
|
kubectl get pods -n kube-system -l name=sealed-secrets-controller
|
||||||
|
```
|
||||||
|
|
||||||
|
### Failed to fetch certificate
|
||||||
|
- Check controller settings (name, namespace, port)
|
||||||
|
- Verify controller is running and accessible
|
||||||
|
|
||||||
|
### Decrypt fails
|
||||||
|
- Ensure SealedSecret status shows "Synced"
|
||||||
|
- Verify RBAC permissions: `kubectl auth can-i get secrets -n <namespace>`
