# 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
