# Docker Swarm Vagrant Cluster
A **production-ready** Docker Swarm cluster with 1 manager and 3 worker nodes for container orchestration and deployment.
## 🐳 Docker Swarm Features
- **1 Swarm Manager** - Cluster orchestration and management
- **3 Swarm Workers** - Container execution and scaling
- **Overlay Networking** - Secure multi-host container communication
- **Service Discovery** - Built-in DNS and load balancing
- **High Availability** - Automatic failover and service recovery
- **Portainer UI** - Web-based cluster management interface
- **Traefik** - Reverse proxy with automatic service discovery
## 🏗️ Architecture
```

```
## 📋 Prerequisites
- **Vagrant** 2.2+
- **VirtualBox** 6.0+ or **libvirt** (KVM)
- **Ansible** 2.9+
- **2GB+ RAM** (512MB per machine + 1GB swap)
- **6GB+ free disk space**
## 🚀 Quick Start
1. **Start all machines:**
```bash
make start
```
2. **Check status:**
```bash
make status
```
3. **Access a machine:**
```bash
make ssh-manager
make ssh-worker1
```
## 🎛️ Management Commands
### Using Make
```bash
make start # Start all machines
make stop # Stop all machines
make destroy # Destroy all machines
make status # Show machine status
make ssh-manager # Access swarm manager
make ssh-worker1 # Access swarm worker1
make ssh-worker2 # Access swarm worker2
make ssh-worker3 # Access swarm worker3
```
### Using Management Script
```bash
./manage.sh start # Start all machines
./manage.sh stop # Stop all machines
./manage.sh destroy # Destroy all machines
./manage.sh status # Show machine status
./manage.sh ssh swarm-manager # Access swarm manager
./manage.sh ssh swarm-worker1 # Access swarm worker1
```
### Using Vagrant Directly
```bash
vagrant up # Start all machines
vagrant halt # Stop all machines
vagrant destroy -f # Destroy all machines
vagrant status # Show machine status
vagrant ssh swarm-manager # Access swarm manager
vagrant ssh swarm-worker1 # Access swarm worker1
```
## 🌐 Network Configuration
- **Swarm Manager**: 192.168.56.10
- **Swarm Worker 1**: 192.168.56.11
- **Swarm Worker 2**: 192.168.56.12
- **Swarm Worker 3**: 192.168.56.13
All machines are connected via a private network and communicate through Docker Swarm overlay networking.
## 🔧 Machine Specifications
- **OS**: Debian 11 (Bullseye)
- **RAM**: 512MB per machine + 1GB swap
- **CPU**: 1 core per machine
- **Disk**: 8GB per machine

## 🛠️ Troubleshooting
### Common Issues
1. **Machines not starting:**
```bash
vagrant status
vagrant up --debug
```
2. **Network issues:**
```bash
vagrant ssh host -c "ping 192.168.56.10"
```
3. **SSH issues:**
```bash
vagrant ssh-config
```
### Useful Commands
```bash
# Check machine status
vagrant status
# View machine details
vagrant ssh-config
# Reload machines
vagrant reload
# Provision machines
vagrant provision
```
## 🐧 Debian Linux Notes
### **Package Management**
```bash
# Update package index
apt update
# Install packages
apt install package-name
# Search packages
apt search keyword
```
### **Common Debian Commands**
```bash
# Check system info
uname -a
cat /etc/os-release
# Check memory usage
free -m
# Check disk usage
df -h
```
## 🎭 Ansible Integration
### **Prerequisites**
```bash
# Install Ansible (on your host machine)
pip install ansible
# Or on Ubuntu/Debian
sudo apt install ansible
```
### **Ansible Commands**
```bash
# Test connectivity to all hosts
make ansible-ping
# Install dependencies (Python, tools, swap)
make ansible-setup
# Deploy applications and services
make ansible-deploy
# List all hosts
make ansible-list
# Gather system facts
make ansible-facts
```
### **Using Management Script**
```bash
# Test Ansible connectivity
./manage.sh ansible ping
# Install dependencies
./manage.sh ansible setup
# Deploy applications
./manage.sh ansible deploy
```
### **Direct Ansible Commands**
```bash
# Test connectivity
ansible all -i inventory -m ping
# Run setup playbook
ansible-playbook -i inventory setup-playbook.yml
# Run deployment playbook
ansible-playbook -i inventory deploy-playbook.yml
# Run on specific hosts
ansible-playbook -i inventory deploy-playbook.yml --limit machines
# Run with verbose output
ansible-playbook -i inventory deploy-playbook.yml -v
```
## 🚀 Next Steps
This is a bare-bones Debian setup. You can extend it by:
1. **Adding provisioning scripts** to install Debian packages
2. **Setting up networking** between machines
3. **Installing Docker** (Debian has excellent Docker support)
4. **Adding lightweight services** (nginx, redis, etc.)
5. **Setting up monitoring** with lightweight tools
