# HMAC File Server - Podman Configuration Examples
This directory contains Podman-specific deployment files for HMAC File Server 3.2 "Tremora del Terra".
## 🚀 Quick Start
```bash
# Clone repository
git clone https://github.com/PlusOne/hmac-file-server.git
cd hmac-file-server/dockerenv/podman
# Deploy with single command
./deploy-podman.sh
# Check status
./deploy-podman.sh status
# View logs
./deploy-podman.sh logs
```
## 📁 Files Overview
### `Dockerfile.podman`
- **Purpose**: Optimized Dockerfile for Podman deployment
- **Features**:
- Security-hardened Alpine-based image
- Non-root user (UID 1011)
- Health checks included
- Static binary compilation
- Minimal attack surface
### `deploy-podman.sh`
- **Purpose**: Complete deployment automation script
- **Features**:
- Interactive deployment with colored output
- Automatic configuration generation with random secrets
- Security-hardened container settings
- Pod management for XMPP integration
- Health monitoring and status reporting
### `hmac-file-server.service`
- **Purpose**: Systemd service unit for service management
- **Usage**: Place in `~/.config/systemd/user/` (rootless) or `/etc/systemd/system/` (system-wide)
## 🛠️ Deployment Commands
### Basic Deployment
```bash
# Full deployment (directories, config, build, start)
./deploy-podman.sh deploy
# Start services only
./deploy-podman.sh start
# Stop all services
./deploy-podman.sh stop
# Restart services
./deploy-podman.sh restart
```
### Management Commands
```bash
# Check status and health
./deploy-podman.sh status
# View real-time logs
./deploy-podman.sh logs
# Show current configuration
./deploy-podman.sh config
# Build image only
./deploy-podman.sh build
# Create networking pod only
./deploy-podman.sh pod
# Complete cleanup (keeps data)
./deploy-podman.sh clean
```
## 🔧 Configuration
### Environment Variables
```bash
# Custom data directory
export APP_DATA="/custom/path/hmac-file-server"
# Custom ports
export LISTEN_PORT="9999"
export METRICS_PORT="9998"
# Deploy with custom settings
./deploy-podman.sh
```
### Generated Configuration
The deployment script generates a production-ready configuration with:
-**XMPP-compatible file extensions**
-**Random HMAC and JWT secrets**
-**Optimized performance settings**
-**Security hardening enabled**
-**Comprehensive logging**
## 🔒 Security Features
### Container Security
- **Rootless operation**: Runs as non-root user (UID 1011)
- **Capability dropping**: `--cap-drop=ALL`
- **No new privileges**: `--security-opt no-new-privileges`
- **Read-only filesystem**: `--read-only` with tmpfs for /tmp
- **SELinux labels**: Volume mounts with `:Z` labels
### Network Security
- **Pod isolation**: Containers run in isolated pods
- **Port binding**: Only necessary ports exposed
- **Health monitoring**: Built-in health checks
## 🔄 Systemd Integration
### User Service (Rootless - Recommended)
```bash
# Copy service file
cp hmac-file-server.service ~/.config/systemd/user/
# Enable and start
systemctl --user daemon-reload
systemctl --user enable hmac-file-server.service
systemctl --user start hmac-file-server.service
# Check status
systemctl --user status hmac-file-server.service
```
### System Service (Root)
```bash
# Copy service file
sudo cp hmac-file-server.service /etc/systemd/system/
# Enable and start
sudo systemctl daemon-reload
sudo systemctl enable hmac-file-server.service
sudo systemctl start hmac-file-server.service
# Check status
sudo systemctl status hmac-file-server.service
```
## 🎯 XMPP Integration
### Pod-based XMPP Deployment
```bash
# Create XMPP services pod
podman pod create --name xmpp-services \
--publish 5222:5222 \
--publish 5269:5269 \
--publish 5443:5443 \
--publish 8888:8888
# Add Prosody XMPP server
podman run -d --pod xmpp-services --name prosody \
-v ./prosody-config:/etc/prosody:ro \
-v ./prosody-data:/var/lib/prosody:rw \
docker.io/prosody/prosody:latest
# Add HMAC File Server
podman run -d --pod xmpp-services --name hmac-file-server \
-v ./config.toml:/app/config.toml:ro \
-v ./data:/data:rw \
localhost/hmac-file-server:latest -config /app/config.toml
```
## 📊 Monitoring and Health
### Health Checks
```bash
# Manual health check
curl -f http://localhost:8888/health
# Container health status
podman healthcheck run hmac-file-server
# Continuous monitoring
watch -n 5 'curl -s http://localhost:8888/health && echo " - $(date)"'
```
### Metrics
```bash
# Prometheus metrics
curl http://localhost:9090/metrics
# Pod statistics
podman pod stats xmpp-pod
# Container logs
podman logs -f hmac-file-server
```
## 🚨 Troubleshooting
### Common Issues
#### Permission Errors
```bash
# Fix SELinux contexts
restorecon -R /opt/podman/hmac-file-server
# Check volume permissions
podman unshare ls -la /opt/podman/hmac-file-server
```
#### Container Won't Start
```bash
# Check image exists
podman images | grep hmac-file-server
# Validate configuration
./deploy-podman.sh config
# Debug with interactive container
podman run -it --rm localhost/hmac-file-server:latest /bin/sh
```
#### Network Issues
```bash
# Check pod networking
podman pod ps
podman port hmac-file-server
# Test connectivity
nc -zv localhost 8888
```
### Log Analysis
```bash
# Container logs
podman logs hmac-file-server
# Application logs
tail -f /opt/podman/hmac-file-server/logs/hmac-file-server.log
# System journal
journalctl --user -u hmac-file-server.service -f
```
## 🎉 Success Verification
After deployment, verify everything works:
1. **Health Check**: `curl -f http://localhost:8888/health`
2. **Metrics**: `curl http://localhost:9090/metrics`
3. **Container Status**: `podman ps`
4. **Pod Status**: `podman pod ps`
5. **Logs**: `./deploy-podman.sh logs`
