Add comprehensive plugin usage examples for Docker, Kubernetes, and Swarm
- Introduced multiple detailed plugin examples for Cloudflare IP restoration, IP whitelisting, JWT validation, and combined usage. - Added configurations for `docker-compose`, `Kubernetes`, and `Swarm` showcasing individual and multi-plugin use cases. - Included clear prerequisites, setup steps, and testing procedures for each example. - Documented advanced scenarios like path blocking, custom IP lists, and JWT validation for production environments.

## Plugin Examples
|
||||
|
||||
### JWT Validator Plugin
|
||||
|
||||
Secure your API with JWT token validation in Swarm:
|
||||
|
||||
```yaml
|
||||
version: "3"
|
||||
|
||||
services:
|
||||
haproxy:
|
||||
image: byjg/easy-haproxy:4.6.0
|
||||
volumes:
|
||||
- /var/run/docker.sock:/var/run/docker.sock
|
||||
- jwt_keys:/etc/haproxy/jwt_keys
|
||||
deploy:
|
||||
replicas: 1
|
||||
environment:
|
||||
EASYHAPROXY_DISCOVER: swarm
|
||||
ports:
|
||||
- "80:80/tcp"
|
||||
- "443:443/tcp"
|
||||
networks:
|
||||
- easyhaproxy
|
||||
|
||||
api:
|
||||
image: my-api:latest
|
||||
deploy:
|
||||
replicas: 5
|
||||
labels:
|
||||
easyhaproxy.http.host: "api.example.com"
|
||||
easyhaproxy.http.port: "80"
|
||||
easyhaproxy.http.localport: "8080"
|
||||
# Enable JWT validation
|
||||
easyhaproxy.http.plugins: "jwt_validator"
|
||||
easyhaproxy.http.plugin.jwt_validator.algorithm: "RS256"
|
||||
easyhaproxy.http.plugin.jwt_validator.issuer: "https://auth.example.com/"
|
||||
easyhaproxy.http.plugin.jwt_validator.audience: "https://api.example.com"
|
||||
easyhaproxy.http.plugin.jwt_validator.pubkey_path: "/etc/haproxy/jwt_keys/api_pubkey.pem"
|
||||
networks:
|
||||

|
||||
|

||||
easyhaproxy:
|
||||
external: true
|
||||
|
||||
volumes:
|
||||
jwt_keys:
|
||||
```
|
||||
|
||||
**Deploy public key using Docker config:**
|
||||
```bash
|
||||
# Create Docker config with public key
|
||||
docker config create jwt_api_pubkey ./api_pubkey.pem
|
||||
|
||||
# Update EasyHAProxy service to use config
|
||||
docker service update \
|
||||
--config-add source=jwt_api_pubkey,target=/etc/haproxy/jwt_keys/api_pubkey.pem \
|
||||
easyhaproxy_haproxy
|
||||
```
|
||||
|
||||
**Test:**
|
||||
```bash
|
||||
# Without token
|
||||
curl http://api.example.com/users
|
||||
# Response: Missing Authorization HTTP header
|
||||
|
||||
# With valid token
|
||||
curl -H "Authorization: Bearer eyJhbGc..." http://api.example.com/users
|
||||
# Response: Success
|
||||
```

#
|
||||
# 2. Create overlay network:
|
||||

|
||||
#
|
||||
# Note: This plugin is most useful when your site is actually behind Cloudflare.

# JWT Validator Plugin Example for Docker Swarm
|
||||
#
|
||||
# This example demonstrates JWT token validation for API protection in Swarm
|
||||
#
|
||||
# Prerequisites:
|
||||
# 1. Docker Swarm initialized:
|
||||
# docker swarm init
|
||||
#
|
||||
# 2. Create overlay network:
|
||||
# docker network create --driver overlay --attachable easyhaproxy
|
||||
#
|
||||
# 3. Generate JWT keys and create Docker config:
|
||||
# openssl genrsa -out jwt_private.pem 2048
|
||||
# openssl rsa -in jwt_private.pem -pubout -out jwt_pubkey.pem
|
||||
# docker config create jwt_api_pubkey jwt_pubkey.pem
|
||||
#
|
||||
# 4. Deploy the stack:
|
||||
# docker stack deploy -c jwt-validator.yml api
|
||||
#
|
||||
# 5. Test without token (should fail):
|
||||
# curl http://<swarm-ip>/
|
||||
# # Response: Missing Authorization HTTP header
|
||||
#
|
||||
# 6. Generate test JWT at https://jwt.io with:
|
||||
# - Algorithm: RS256
|
||||
# - Payload: {"iss":"https://auth.example.com/","aud":"https://api.example.com","exp":9999999999}
|
||||
# - Use your jwt_private.pem for signing
|
||||
#
|
||||
# 7. Test with token:
|
||||
# TOKEN="eyJhbGc..."
|
||||
# curl -H "Authorization: Bearer $TOKEN" http://<swarm-ip>/
|
||||
# # Response: Success

# Multiple Plugins Combined Example for Docker Swarm
|
||||
#
|
||||
# This example demonstrates using multiple plugins together for enhanced security
|
||||
#
|
||||
# Prerequisites:
|
||||
# 1. Docker Swarm initialized:
|
||||
# docker swarm init
|
||||
#
|
||||
# 2. Create overlay network:
|
||||
# docker network create --driver overlay --attachable easyhaproxy
|
||||
#
|
||||
# 3. Generate JWT keys and create Docker config:
|
||||
# openssl genrsa -out jwt_private.pem 2048
|
||||
# openssl rsa -in jwt_private.pem -pubout -out jwt_pubkey.pem
|
||||
# docker config create jwt_api_pubkey jwt_pubkey.pem
|
||||
#
|
||||
# 4. Download Cloudflare IPs and create Docker config:
|
||||
# curl https://www.cloudflare.com/ips-v4 > cloudflare_ips.lst
|
||||
# curl https://www.cloudflare.com/ips-v6 >> cloudflare_ips.lst
|
||||
# docker config create cloudflare_ips cloudflare_ips.lst
|
||||
#
|
||||
# 5. Deploy the stack:
|
||||
# docker stack deploy -c plugins-combined.yml production
|
||||
#
|
||||
# This creates three services with different security profiles:
|
||||
# - Public website: Cloudflare + path blocking
|
||||
# - Protected API: JWT validation + path blocking
|
||||
# - Admin panel: Strict IP whitelist
