Add support for existing Secrets and External Secrets Operator
Enhanced secret management for API7 Gateway credentials with support for existing Secrets and External Secrets Operator integration. Changes: 1. Secret Configuration: - Added api7.gateway.existingSecret parameter for using existing secrets - Added api7.gateway.existingSecretKeys for custom key names - Modified secret-api7.yaml to only create secret if existingSecret is empty - Updated job-adc-sync.yaml to reference configurable secret name 2. Values.yaml Documentation: - Added comprehensive documentation for secret configuration options - Documented two approaches: inline config (dev) vs existing secret (prod) - Added example kubectl command for creating secrets manually - Included instructions for obtaining admin key from API7 EE 3. External Secrets Support: - Created externalsecret-api7.yaml.example with complete examples - Included examples for AWS Secrets Manager and HashiCorp Vault - Documented SecretStore configuration patterns 4. Documentation: - Created SECRET-MANAGEMENT.md comprehensive guide - Covered all secret management options (inline, manual, external) - Added security best practices and troubleshooting guide - Included examples for External Secrets Operator setup Benefits: - Improved security: Secrets not stored in values.yaml - Flexibility: Support for any secret management tool - Production-ready: Works with External Secrets Operator - Better practices: Clear separation of config vs secrets 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# Secret Management for API7 Gateway
|
||||
|
||||
This document explains how to manage API7 Gateway credentials securely.
|
||||
|
||||
## Overview
|
||||
|
||||
API7 Gateway requires the following credentials:
|
||||
- **Admin URL**: Dashboard admin API endpoint
|
||||
- **Admin Key**: Authentication token for admin API
|
||||
- **Gateway Group**: Logical grouping of gateway instances
|
||||
|
||||
## Configuration Options
|
||||
|
||||
### Option 1: Inline Configuration (Development Only)
|
||||
|
||||
**⚠️ NOT RECOMMENDED for production**
|
||||
|
||||
Credentials are stored directly in `values.yaml`:
|
||||
|
||||
```yaml
|
||||
api7:
|
||||
gateway:
|
||||
existingSecret: "" # Leave empty
|
||||
adminUrl: https://api7ee3-0-1759339083-dashboard:7443
|
||||
adminKey: "your-admin-key"
|
||||
group: default
|
||||
```
|
||||
|
||||
The chart will create a Kubernetes Secret automatically.
|
||||
|
||||
### Option 2: Existing Secret (Recommended)
|
||||
|
||||
**✅ RECOMMENDED for production**
|
||||
|
||||
Create a Secret manually or using a secret management tool, then reference it:
|
||||
|
||||
```yaml
|
||||
api7:
|
||||
gateway:
|
||||
existingSecret: "api7-credentials" # Name of your secret
|
||||
existingSecretKeys:
|
||||
adminUrl: admin-url
|
||||
adminKey: admin-key
|
||||
group: gateway-group
|
||||
```
|
||||
|
||||
#### Create Secret Manually
|
||||
|
||||
```bash
|
||||
kubectl create secret generic api7-credentials \
|
||||
--from-literal=admin-url=https://api7ee3-0-1759339083-dashboard:7443 \
|
||||
--from-literal=admin-key=YOUR_ADMIN_KEY \
|
||||
--from-literal=gateway-group=default \
|
||||
-n api7ee
|
||||
```
|
||||
|
||||
#### Get Admin Key from API7 Enterprise
|
||||
|
||||
```bash
|
||||
# Get admin key from API7 Enterprise installation
|
||||
kubectl get secret -n api7ee api7ee3-0-1759339083 \
|
||||
-o jsonpath='{.data.admin_key}' | base64 -d
|
||||
```
|
||||
|
||||
### Option 3: External Secrets Operator
|
||||
|
||||
**✅ RECOMMENDED for production with centralized secret management**
|
||||
|
||||
Use External Secrets Operator to sync secrets from external providers like:
|
||||
- AWS Secrets Manager
|
||||
- HashiCorp Vault
|
||||
- Azure Key Vault
|
||||
- GCP Secret Manager
|
||||
- And more...
|
||||
|
||||
#### Step 1: Install External Secrets Operator
|
||||
|
||||
```bash
|
||||
helm repo add external-secrets https://charts.external-secrets.io
|
||||
helm install external-secrets external-secrets/external-secrets -n external-secrets-system --create-namespace
|
||||
```
|
||||
|
||||
#### Step 2: Configure SecretStore
|
||||
|
||||
Example for HashiCorp Vault:
|
||||
|
||||
```yaml
|
||||
apiVersion: external-secrets.io/v1beta1
|
||||
kind: SecretStore
|
||||
metadata:
|
||||
name: vault-backend
|
||||
namespace: api7ee
|
||||
spec:
|
||||
provider:
|
||||
vault:
|
||||
server: "https://vault.example.com"
|
||||
path: "secret"
|
||||
version: "v2"
|
||||
auth:
|
||||
kubernetes:
|
||||
mountPath: "kubernetes"
|
||||
role: "api7-role"
|
||||
serviceAccountRef:
|
||||
name: api7ee-demo-api7ee-demo-k8s
|
||||
```
|
||||
|
||||
#### Step 3: Create ExternalSecret
|
||||
|
||||
See `templates/externalsecret-api7.yaml.example` for a complete example.
|
||||
|
||||
```yaml
|
||||
apiVersion: external-secrets.io/v1beta1
|
||||
kind: ExternalSecret
|
||||
metadata:
|
||||
name: api7-credentials-external
|
||||
namespace: api7ee
|
||||
spec:
|
||||
refreshInterval: 1h
|
||||
secretStoreRef:
|
||||
name: vault-backend
|
||||
kind: SecretStore
|
||||
target:
|
||||
name: api7-credentials
|
||||
creationPolicy: Owner
|
||||
data:
|
||||
- secretKey: admin-url
|
||||
remoteRef:
|
||||
key: api7/gateway
|
||||
property: admin_url
|
||||
- secretKey: admin-key
|
||||
remoteRef:
|
||||
key: api7/gateway
|
||||
property: admin_key
|
||||
- secretKey: gateway-group
|
||||
remoteRef:
|
||||
key: api7/gateway
|
||||
property: gateway_group
|
||||
```
|
||||
|
||||
#### Step 4: Configure Helm Values
|
||||
|
||||
```yaml
|
||||
api7:
|
||||
gateway:
|
||||
existingSecret: "api7-credentials" # Created by ExternalSecret
|
||||
```
|
||||
|
||||
## Secret Keys
|
||||
|
||||
The Secret must contain these keys (default names):
|
||||
|
||||
| Key | Description | Example |
|
||||
|-----|-------------|---------|
|
||||
| `admin-url` | Dashboard admin API URL | `https://api7ee3-0-1759339083-dashboard:7443` |
|
||||
| `admin-key` | Dashboard admin API key | `edd1c9f034335f136f87ad84b625c8f1` |
|
||||
| `gateway-group` | Gateway group name | `default` |
|
||||
|
||||
### Custom Key Names
|
||||
|
||||
If your Secret uses different key names, configure them:
|
||||
|
||||
```yaml
|
||||
api7:
|
||||
gateway:
|
||||
existingSecret: "my-custom-secret"
|
||||
existingSecretKeys:
|
||||
adminUrl: dashboard_url # Your custom key name
|
||||
adminKey: api_token # Your custom key name
|
||||
group: group_name # Your custom key name
|
||||
```
|
||||
|
||||
## Security Best Practices
|
||||
|
||||
1. **Never commit secrets to Git**
|
||||
- Use `.gitignore` for values files containing secrets
|
||||
- Use secret management tools for production
|
||||
|
||||
2. **Use RBAC to restrict secret access**
|
||||
- Limit which ServiceAccounts can read secrets
|
||||
- Use namespace isolation
|
||||
|
||||
3. **Rotate credentials regularly**
|
||||
- Update admin keys periodically
|
||||
- Use External Secrets Operator for automatic rotation
|
||||
|
||||
4. **Enable audit logging**
|
||||
- Monitor secret access in Kubernetes audit logs
|
||||
- Alert on unauthorized access attempts
|
||||
|
||||
5. **Use encryption at rest**
|
||||
- Enable Kubernetes secret encryption
|
||||
- Use external KMS for additional security
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Secret not found
|
||||
|
||||
```bash
|
||||
# Check if secret exists
|
||||
kubectl get secret -n api7ee
|
||||
|
||||
# Describe the secret
|
||||
kubectl describe secret api7-credentials -n api7ee
|
||||
```
|
||||
|
||||
### Invalid credentials
|
||||
|
||||
```bash
|
||||
# View secret data (base64 encoded)
|
||||
kubectl get secret api7-credentials -n api7ee -o yaml
|
||||
|
||||
# Decode and verify values
|
||||
kubectl get secret api7-credentials -n api7ee \
|
||||
-o jsonpath='{.data.admin-key}' | base64 -d
|
||||
```
|
||||
|
||||
### ADC sync job fails
|
||||
|
||||
```bash
|
||||
# Check job logs
|
||||
kubectl logs -n api7ee job/api7ee-demo-api7ee-demo-k8s-adc-sync
|
||||
|
||||
# Common issues:
|
||||
# - Wrong admin URL (check DNS resolution)
|
||||
# - Invalid admin key (verify key is correct)
|
||||
# - TLS certificate issues (use tlsSkipVerify: true for self-signed)
|
||||
```
