# Docker Swarm Examples
|
||||
|
||||
This directory contains Docker Swarm stack examples demonstrating EasyHAProxy in a Swarm cluster environment.
|
||||
|
||||
## What is Docker Swarm Mode?
|
||||
|
||||
Docker Swarm mode enables:
|
||||
- **Service orchestration** across multiple nodes
|
||||
- **Service scaling** with replicas
|
||||
- **Load balancing** across service replicas
|
||||
- **Rolling updates** with zero downtime
|
||||
- **Service discovery** via overlay networks
|
||||
|
||||
EasyHAProxy automatically discovers Swarm services and routes traffic based on service labels.
|
||||
|
||||
---
|
||||
|
||||
## Prerequisites
|
||||
|
||||
### 1. Initialize Docker Swarm
|
||||
|
||||
```bash
|
||||
# On manager node
|
||||
docker swarm init
|
||||
|
||||
# On worker nodes (use token from swarm init output)
|
||||
docker swarm join --token <token> <manager-ip>:2377
|
||||
```
|
||||
|
||||
### 2. Create Overlay Network
|
||||
|
||||
```bash
|
||||
# Create attachable overlay network for EasyHAProxy
|
||||
docker network create --driver overlay --attachable easyhaproxy
|
||||
```
|
||||
|
||||
**Why attachable?** Allows both swarm services and standalone containers to connect.
|
||||
|
||||

|
||||
|
||||
## Files in This Directory
|
||||
|
||||
- `easyhaproxy.yml` - EasyHAProxy service stack
|
||||
- `services.yml` - Example application services
|
||||
- `portainer.yml` - Portainer management interface
|
||||
- `certs/` - Directory for SSL certificates
|
||||
|
||||
---
|
||||
|
||||
## Prerequisites: Generate SSL Certificates
|
||||
|
||||
**IMPORTANT:** Before running any examples, you must generate the required SSL certificates:
|
||||
|
||||
```bash
|
||||
# From the repository root
|
||||
./examples/generate-keys.sh
|
||||
```
|
||||
|
||||
This script automatically generates:
|
||||
- SSL certificates for host1.local and host2.local (placed in `examples/swarm/certs/`)
|
||||
- JWT keys for authentication examples
|
||||
- All other .pem files needed for testing
|
||||
|
||||
**Note:** These are self-signed certificates for testing only. Do not use in production.
|
||||
|
||||
---
|
||||
Self-contained examples for EasyHAProxy in Docker Swarm mode. **All documentation is in the YAML files as header comments.**
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Deploy EasyHAProxy
|
||||
1. Pick an example below
|
||||
2. Open the YAML file
|
||||
3. Read the header comments for complete instructions
|
||||
4. Run the commands step-by-step
|
||||
|
||||
```bash
|
||||
cd examples/swarm
|
||||
## Prerequisites
|
||||
|
||||
# Edit easyhaproxy.yml and change:
|
||||
# EASYHAPROXY_CERTBOT_EMAIL: your-email@example.com
|
||||
All examples require:
|
||||
- Docker Swarm initialized (`docker swarm init`)
|
||||
- Overlay network created (`docker network create --driver overlay --attachable easyhaproxy`)
|
||||
- EasyHAProxy deployed (`docker stack deploy -c easyhaproxy.yml easyhaproxy`)
|
||||
|
||||
# Deploy stack
|
||||
docker stack deploy -c easyhaproxy.yml easyhaproxy
|
||||
```
|
||||
See header comments in each file for detailed setup instructions.
|
||||
|
||||
**What this creates:**
|
||||
- EasyHAProxy service with 1 replica
|
||||
- Exposed ports: 80, 443, 1936
|
||||
- Mounts Docker socket for service discovery
|
||||
- Mounts volume for certbot certificates
|
||||

## Example Files Explained
|
||||
## Important: Service Labels
|
||||
|
||||
### easyhaproxy.yml
|
||||
|
||||
```yaml
|
||||
services:
|
||||
haproxy:
|
||||
image: byjg/easy-haproxy:4.6.0
|
||||
volumes:
|
||||
- /var/run/docker.sock:/var/run/docker.sock # Service discovery
|
||||
- ./certs:/certs/haproxy # SSL certificates
|
||||
- certs_certbot:/certs/certbot # Let's Encrypt certs
|
||||
deploy:
|
||||
replicas: 1 # Single instance
|
||||
environment:
|
||||
EASYHAPROXY_DISCOVER: swarm # Swarm mode!
|
||||
EASYHAPROXY_SSL_MODE: "loose"
|
||||
EASYHAPROXY_CERTBOT_EMAIL: changeme@example.org # Change this!
|
||||
HAPROXY_CUSTOMERRORS: "true"
|
||||
HAPROXY_USERNAME: admin
|
||||
HAPROXY_PASSWORD: password
|
||||
HAPROXY_STATS_PORT: 1936
|
||||
ports:
|
||||
- "80:80/tcp"
|
||||
- "443:443/tcp"
|
||||
- "1936:1936/tcp"
|
||||
networks:
|
||||
- easyhaproxy # Overlay network
|
||||
|
||||
networks:
|
||||
easyhaproxy:
|
||||
external: true # Created separately
|
||||
|
||||
volumes:
|
||||
certs_certbot: # Persistent certbot data
|
||||
```
|
||||
|
||||
**Key differences from Docker Compose mode:**
|
||||
- `EASYHAPROXY_DISCOVER: swarm` - Discovery mode
|
||||
- `deploy.replicas: 1` - Swarm deployment config
|
||||
- External overlay network
|
||||
|
||||
---
|
||||
|
||||
## Service Labels in Swarm
|
||||
|
||||
Service labels are similar to container labels but applied to **services**, not containers.
|
||||
|
||||
### Basic Service Example
|
||||
|
||||
```yaml
|
||||
services:
|
||||
webapp:
|
||||
image: nginx:alpine
|
||||
deploy:
|
||||
replicas: 3 # 3 instances for load balancing
|
||||
labels:
|
||||
# Service labels (not container labels!)
|
||||
easyhaproxy.http.host: "webapp.example.com"
|
||||
easyhaproxy.http.port: "80"
|
||||
easyhaproxy.http.localport: "80"
|
||||
networks:
|
||||
- easyhaproxy
|
||||
```
|
||||
|
||||
**Important:** Use `deploy.labels`, NOT top-level `labels`!
|
||||
In Swarm mode, labels must be under `deploy.labels`, NOT top-level `labels`:
|
||||
|
||||
```yaml
|
||||
# ✅ CORRECT - Service labels
|
||||
|
|
@ -177,760 +59,9 @@ labels:
|
|||
easyhaproxy.http.host: example.com
|
||||
```

|
||||
|
||||
**Security layers:**
|
||||
- **Website**: Cloudflare IP restoration + path blocking
|
||||
- **API**: Cloudflare + JWT validation + internal path blocking
|
||||
- **Admin**: Strict IP whitelist (office network only)
|
||||
|
||||

|
||||
|
||||
## Scaling Services
|
||||
|
||||
Scale services dynamically:
|
||||
|
||||
```bash
|
||||
# Scale up
|
||||
docker service scale myapp_webapp=10
|
||||
|
||||
# Scale down
|
||||
docker service scale myapp_webapp=2
|
||||
|
||||
# Check replicas
|
||||
docker service ls
|
||||
```
|
||||
|
||||
EasyHAProxy automatically detects all replicas and load balances across them.
|
||||
|
||||
---
|
||||
|
||||
## Rolling Updates
|
||||
|
||||
Update services with zero downtime:
|
||||
|
||||
```bash
|
||||
# Update service image
|
||||
docker service update --image webapp:v2 myapp_webapp
|
||||
|
||||
# Update with custom settings
|
||||
docker service update \
|
||||
--image webapp:v2 \
|
||||
--update-parallelism 2 \
|
||||
--update-delay 10s \
|
||||
myapp_webapp
|
||||
```
|
||||
|
||||
EasyHAProxy continues routing to healthy containers during rollout.
|
||||

|
||||
|
||||
## SSL Certificates in Swarm
|
||||
|
||||
### Option 1: Let's Encrypt (Recommended)
|
||||
|
||||
Configure in `easyhaproxy.yml`:
|
||||
```yaml
|
||||
environment:
|
||||
EASYHAPROXY_CERTBOT_EMAIL: your-email@example.com
|
||||
```
|
||||
|
||||
Enable per-service:
|
||||
```yaml
|
||||
deploy:
|
||||
labels:
|
||||
easyhaproxy.http.certbot: "true"
|
||||
```
|
||||
|
||||
### Option 2: Custom Certificates
|
||||
|
||||
Mount certificates directory:
|
||||
```yaml
|
||||
# easyhaproxy.yml
|
||||
volumes:
|
||||
- ./certs:/certs/haproxy
|
||||
```
|
||||
|
||||
Place certificate files:
|
||||
```bash
|
||||
./certs/
|
||||
├── example.com.pem
|
||||
├── api.example.com.pem
|
||||
└── secure.example.com.pem
|
||||
```
|
||||
|
||||
### Option 3: Docker Secrets (Production)
|
||||
|
||||
```bash
|
||||
# Create secret
|
||||
docker secret create example_com_cert ./example.com.pem
|
||||
|
||||
# Use in stack
|
||||
|
||||
services:
|
||||
haproxy:
|
||||
secrets:
|
||||
- example_com_cert
|
||||
environment:
|
||||
EASYHAPROXY_SSL_CERT_example_com: /run/secrets/example_com_cert
|
||||
|
||||
secrets:
|
||||
example_com_cert:
|
||||
external: true
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Monitoring and Stats
|
||||
|
||||
### HAProxy Stats Interface
|
||||
|
||||
Access at: `http://<swarm-ip>:1936`
|
||||
- Username: `admin` (configured in `easyhaproxy.yml`)
|
||||
- Password: `password` (configured in `easyhaproxy.yml`)
|
||||
|
||||
### Service Health
|
||||
|
||||
```bash
|
||||
# Check service health
|
||||
docker service ps myapp_webapp
|
||||
|
||||
# View detailed service info
|
||||
docker service inspect --pretty myapp_webapp
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Service Not Detected
|
||||
|
||||
**Check service labels:**
|
||||
```bash
|
||||
docker service inspect myapp_webapp | grep -A 20 Labels
|
||||
```
|
||||
|
||||
Ensure labels are under `deploy.labels`, not top-level `labels`.
|
||||
|
||||
**Check EasyHAProxy logs:**
|
||||
```bash
|
||||
docker service logs -f easyhaproxy_haproxy
|
||||
```
|
||||
|
||||
### Service Unreachable (503)
|
||||
|
||||
**Causes:**
|
||||
- Service containers not ready yet
|
||||
- Wrong network configuration
|
||||
- Service crashed
|
||||
|
||||
**Debug:**
|
||||
```bash
|
||||
# Check service is running
|
||||
docker service ps myapp_webapp
|
||||
|
||||
# Check network
|
||||
docker network inspect easyhaproxy
|
||||
|
||||
# Test service directly
|
||||
docker run --rm --network easyhaproxy alpine \
|
||||
wget -O- http://myapp_webapp:8080
|
||||
```
|
||||
|
||||
### Overlay Network Issues
|
||||
|
||||
**Create network if missing:**
|
||||
```bash
|
||||
docker network create --driver overlay --attachable easyhaproxy
|
||||
```
|
||||
|
||||
**Verify service is on network:**
|
||||
```bash
|
||||
docker service inspect myapp_webapp | grep -A 5 Networks
|
||||
```
|
||||
|
||||
### EasyHAProxy Not Starting
|
||||
|
||||
**Check Docker socket permissions:**
|
||||
```bash
|
||||
docker service logs easyhaproxy_haproxy
|
||||
```
|
||||
|
||||
**Verify socket is mounted:**
|
||||
```bash
|
||||
docker service inspect easyhaproxy_haproxy | grep -A 5 Mounts
|
||||
```
|
||||
|
||||
### Certificate Issues
|
||||
|
||||
**Certbot fails:**
|
||||
- Ensure swarm is publicly accessible
|
||||
- Check DNS points to swarm IP
|
||||
- Verify ports 80/443 are open
|
||||
- Check certbot logs: `docker service logs easyhaproxy_haproxy | grep certbot`
|
||||
|
||||
**Custom cert not found:**
|
||||
```bash
|
||||
# Exec into service container
|
||||
docker exec -it $(docker ps -q -f name=easyhaproxy) sh
|
||||
ls -la /certs/haproxy/
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## High Availability Setup
|
||||
|
||||
### Multiple Manager Nodes
|
||||
|
||||
```bash
|
||||
# On additional manager nodes
|
||||
docker swarm join-token manager
|
||||
# Use token on new nodes
|
||||
```
|
||||
|
||||
### EasyHAProxy Constraints
|
||||
|
||||
Run EasyHAProxy on specific node:
|
||||
|
||||
```yaml
|
||||
services:
|
||||
haproxy:
|
||||
deploy:
|
||||
placement:
|
||||
constraints:
|
||||
- node.role == manager
|
||||
- node.labels.haproxy == true
|
||||
```
|
||||
|
||||
Label node:
|
||||
```bash
|
||||
docker node update --label-add haproxy=true <node-name>
|
||||
```
|
||||
|
||||
### Multiple EasyHAProxy Replicas
|
||||
|
||||
**Not recommended** - EasyHAProxy should run as single instance because:
|
||||
- Multiple instances would compete for port binding
|
||||
- Use external load balancer (cloud LB, keepalived, etc.) for HA
|
||||
|
||||
**Alternative HA pattern:**
|
||||
```
|
||||
Internet → Cloud Load Balancer → Multiple Swarm Nodes
|
||||
└→ EasyHAProxy (runs on 1 node)
|
||||
└→ Services (distributed across nodes)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Use Overlay Networks:**
|
||||
- Create dedicated network for EasyHAProxy
|
||||
- Use `--attachable` for flexibility
|
||||
|
||||
2. **Service Labels:**
|
||||
- Always use `deploy.labels`, never top-level `labels`
|
||||
- Use clear, descriptive domain names
|
||||
|
||||
3. **Replicas:**
|
||||
- Start with 2-3 replicas per service
|
||||
- Scale based on load monitoring
|
||||
- Use odd number for consensus (3, 5, 7)
|
||||
|
||||
4. **Updates:**
|
||||
- Use rolling updates for zero downtime
|
||||
- Set appropriate `update-delay`
|
||||
- Test in staging first
|
||||
|
||||
5. **Monitoring:**
|
||||
- Enable HAProxy stats
|
||||
- Use Portainer for visual management
|
||||
- Monitor service health regularly
|
||||
|
||||
6. **Security:**
|
||||
- Use Docker secrets for sensitive data
|
||||
- Restrict admin panel access
|
||||
- Use SSL/TLS for production
|
||||
- Apply IP whitelisting for admin interfaces
|
||||
|
||||
7. **Persistence:**
|
||||
- Use volumes for certbot certificates
|
||||
- Backup certificate volumes
|
||||
- Store custom certs in version control (encrypted)

# Cloudflare IP Restoration Plugin Example for Docker Swarm
|
||||
# ==============================================================================
|
||||
# EXAMPLE: Cloudflare IP Restoration (Swarm)
|
||||
# ==============================================================================
|
||||
#
|
||||
# This example demonstrates restoring original visitor IPs when using Cloudflare CDN
|
||||
# WHAT THIS DEMONSTRATES:
|
||||
# - Restoring original visitor IPs when behind Cloudflare CDN
|
||||
# - Using Docker configs to manage Cloudflare IP lists
|
||||
# - Service discovery in Swarm mode with plugins
|
||||
# - Load balancing across multiple replicas
|
||||
#
|
||||
# Prerequisites:
|
||||
# 1. Docker Swarm initialized:
|
||||
# docker swarm init
|
||||
# REQUIREMENTS (run these first):
|
||||
# ```bash
|
||||
# # Initialize Docker Swarm (if not already initialized)
|
||||
# docker swarm init
|
||||
#
|
||||
# 2. Create overlay network:
|
||||
# docker network create --driver overlay --attachable easyhaproxy
|
||||
# # Create overlay network (idempotent)
|
||||
# docker network ls | grep -q easyhaproxy || docker network create --driver overlay --attachable easyhaproxy
|
||||
#
|
||||
# 3. 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
|
||||
# # Ensure EasyHAProxy is deployed
|
||||
# docker stack deploy -c easyhaproxy.yml easyhaproxy
|
||||
#
|
||||
# 4. Deploy the stack:
|
||||
# docker stack deploy -c cloudflare.yml webapp
|
||||
# # Download Cloudflare IP ranges 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
|
||||
# rm cloudflare_ips.lst
|
||||
#
|
||||
# 5. Test:
|
||||
# curl http://<swarm-ip>/
|
||||
# # Add to /etc/hosts for local testing (idempotent)
|
||||
# grep -q "myapp.example.com" /etc/hosts || echo "127.0.0.1 myapp.example.com" | sudo tee -a /etc/hosts
|
||||
# ```
|
||||
#
|
||||
# Note: This plugin is most useful when your site is actually behind Cloudflare.
|
||||
# HOW TO START:
|
||||
# ```bash
|
||||
# docker stack deploy -c cloudflare.yml webapp
|
||||
# ```
|
||||
#
|
||||
# HOW TO VERIFY IT'S WORKING:
|
||||
# ```bash
|
||||
# # Check stack is deployed
|
||||
# docker stack ls | grep webapp
|
||||
# # Expected: webapp stack listed
|
||||
#
|
||||
# # Check service is running
|
||||
# docker service ls | grep webapp_webapp
|
||||
# # Expected: webapp_webapp with 4/4 replicas
|
||||
#
|
||||
# # Test the application
|
||||
# curl -H "Host: myapp.example.com" http://localhost/
|
||||
# # Expected: 200 OK with "App Behind Cloudflare"
|
||||
#
|
||||
# # Check HAProxy config includes Cloudflare IPs
|
||||
# docker exec $(docker ps -q -f name=easyhaproxy_haproxy) cat /etc/haproxy/haproxy.cfg | grep -A 5 "cloudflare"
|
||||
# # Expected: ACL rules for Cloudflare IP ranges
|
||||
# ```
|
||||
#
|
||||
# CLEAN UP:
|
||||
# ```bash
|
||||
# docker stack rm webapp
|
||||
# # To also remove the Cloudflare IPs config:
|
||||
# # docker config rm cloudflare_ips
|
||||
# ```
|
||||
#
|
||||
# NOTE: This plugin is most useful when your site is actually behind Cloudflare CDN.
|
||||
# The plugin uses the CF-Connecting-IP header to restore the original visitor IP.

# IP Whitelist Plugin Example for Docker Swarm
|
||||
# ==============================================================================
|
||||
# EXAMPLE: IP Whitelist Plugin (Swarm)
|
||||
# ==============================================================================
|
||||
#
|
||||
# This example demonstrates restricting access to specific IP addresses in Swarm
|
||||
# WHAT THIS DEMONSTRATES:
|
||||
# - Restricting access to specific IP addresses/networks
|
||||
# - IP-based access control for admin panels or sensitive services
|
||||
# - Returning custom status codes for blocked IPs
|
||||
# - Service discovery in Swarm mode with plugins
|
||||
#
|
||||
# Prerequisites:
|
||||
# 1. Docker Swarm initialized:
|
||||
# docker swarm init
|
||||
# REQUIREMENTS (run these first):
|
||||
# ```bash
|
||||
# # Initialize Docker Swarm (if not already initialized)
|
||||
# docker swarm init
|
||||
#
|
||||
# 2. Create overlay network:
|
||||
# docker network create --driver overlay --attachable easyhaproxy
|
||||
# # Create overlay network (idempotent)
|
||||
# docker network ls | grep -q easyhaproxy || docker network create --driver overlay --attachable easyhaproxy
|
||||
#
|
||||
# 3. Update allowed_ips label with your actual IP addresses/networks
|
||||
# # Ensure EasyHAProxy is deployed
|
||||
# docker stack deploy -c easyhaproxy.yml easyhaproxy
|
||||
#
|
||||
# 4. Deploy the stack:
|
||||
# docker stack deploy -c ip-whitelist.yml admin
|
||||
# # Add to /etc/hosts for local testing (idempotent)
|
||||
# grep -q "admin.example.com" /etc/hosts || echo "127.0.0.1 admin.example.com" | sudo tee -a /etc/hosts
|
||||
#
|
||||
# 5. Test from allowed IP:
|
||||
# curl http://<swarm-ip>/
|
||||
# # Response: Success (200 OK)
|
||||
# # IMPORTANT: Edit this file (ip-whitelist.yml) line 64 to add your actual IP addresses!
|
||||
# # Get your current IP: curl ifconfig.me
|
||||
# ```
|
||||
#
|
||||
# 6. Test from non-allowed IP:
|
||||
# # Response: HTTP 403 Forbidden
|
||||
# HOW TO START:
|
||||
# ```bash
|
||||
# docker stack deploy -c ip-whitelist.yml admin
|
||||
# ```
|
||||
#
|
||||
# HOW TO VERIFY IT'S WORKING:
|
||||
# ```bash
|
||||
# # Check stack is deployed
|
||||
# docker stack ls | grep admin
|
||||
# # Expected: admin stack listed
|
||||
#
|
||||
# # Check service is running
|
||||
# docker service ls | grep admin_admin
|
||||
# # Expected: admin_admin with 3/3 replicas
|
||||
#
|
||||
# # Test from allowed IP (assumes 127.0.0.1 or your IP is in the whitelist)
|
||||
# curl -H "Host: admin.example.com" http://localhost/
|
||||
# # Expected: 200 OK with "Admin Panel - IP Restricted"
|
||||
#
|
||||
# # Test from blocked IP (using a different IP via proxy or VPN)
|
||||
# # Expected: HTTP 403 Forbidden

# ==============================================================================
|
||||
#
|
||||
# This example demonstrates JWT token validation for API protection in Swarm
|
||||
# WHAT THIS DEMONSTRATES:
|
||||
# - JWT token validation for API authentication
|
||||
# - Using Docker configs to manage JWT public keys
|
||||
# - Validating issuer, audience, and expiration claims
|
||||
# - Service discovery in Swarm mode with plugins
|
||||
#
|
||||
# Prerequisites:
|
||||
# 1. Docker Swarm initialized:
|
||||
# docker swarm init
|
||||
# REQUIREMENTS (run these first):
|
||||
# ```bash
|
||||
# # Initialize Docker Swarm (if not already initialized)
|
||||
# docker swarm init
|
||||
#
|
||||
# 2. Create overlay network:
|
||||

# ==============================================================================
|
||||
# EXAMPLE: Multiple Plugins Combined (Swarm)
|
||||
# ==============================================================================
|
||||
#
|
||||
# This example demonstrates using multiple plugins together for enhanced security
|
||||
# WHAT THIS DEMONSTRATES:
|
||||
# - Using multiple plugins together for layered security
|
||||
# - Three different security profiles for different service types:
|
||||
# * Public website: Cloudflare IP restoration + path blocking
|
||||
# * Protected API: JWT authentication + path blocking
|
||||
# * Admin panel: Strict IP whitelist
|
||||
# - Complex production-ready security configuration
|
||||
#
|
||||
# Prerequisites:
|
||||
# 1. Docker Swarm initialized:
|
||||
# docker swarm init
|
||||
# REQUIREMENTS (run these first):
|
||||
# ```bash
|
||||
# # Initialize Docker Swarm (if not already initialized)
|
||||
# docker swarm init

#
|
||||
# 2. Create overlay network:
|
||||
# docker network create --driver overlay --attachable easyhaproxy
|
||||
# # Create overlay network (idempotent)
|
||||
# docker network ls | grep -q easyhaproxy || 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
|
||||
# # Ensure EasyHAProxy is deployed
|
||||
# docker stack deploy -c easyhaproxy.yml easyhaproxy
|
||||
#
|
||||
# 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
|
||||
# # Generate JWT key pair (RS256 algorithm)
|
||||
# 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
|
||||
#
|
||||
# 5. Deploy the stack:
|
||||
# docker stack deploy -c plugins-combined.yml production
|
||||
# # Download Cloudflare IP ranges 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
|
||||
# rm cloudflare_ips.lst jwt_private.pem jwt_pubkey.pem
|
||||
#
|
||||
# This creates three services with different security profiles:
|
||||
# - Public website: Cloudflare + path blocking
|
||||
# - Protected API: JWT validation + path blocking
|
||||
# - Admin panel: Strict IP whitelist
|
||||
# # Add to /etc/hosts for local testing (idempotent)
|
||||
# grep -q "website.example.com" /etc/hosts || echo "127.0.0.1 website.example.com api.example.com admin.example.com" | sudo tee -a /etc/hosts
|
||||
#
|
||||
# # IMPORTANT: Edit this file (plugins-combined.yml) line 124 to add your actual IP!
