+## Podman Deployment
+
+### Podman Build and Run (Alternative to Docker)
+
+Podman is a daemonless container engine that's often preferred in enterprise environments for its security and rootless capabilities.
+
+#### Build Container Image with Podman
+```bash
+# Clone repository
+git clone https://github.com/PlusOne/hmac-file-server.git
+cd hmac-file-server
+
+# Build image with Podman
+podman build --no-cache -t localhost/hmac-file-server:latest -f Dockerfile.podman .
+```
+
+#### Optimized Podman Dockerfile
+```dockerfile
+# Dockerfile.podman - Optimized for Podman deployment
+FROM docker.io/golang:1.24-alpine AS builder
+
+WORKDIR /build
+
+# Install build dependencies

+### Podman vs Docker Comparison
+
+| Feature | Docker | Podman |
+|---------|--------|--------|
+| **Daemon** | Requires Docker daemon | Daemonless architecture |
+| **Root Access** | Requires root for Docker daemon | Can run completely rootless |
+| **Security** | Good, but daemon runs as root | Enhanced security, no privileged daemon |
+| **Systemd Integration** | Via Docker service | Native systemd integration |
+| **Pod Support** | Requires docker-compose or swarm | Native Kubernetes-style pods |
+| **Image Compatibility** | Docker images | Compatible with Docker images |

+
+### Quick Start Commands
+
+```bash
+# Complete deployment in one command
+cd hmac-file-server/dockerenv/podman && ./deploy-podman.sh
+
+# Manual deployment
+podman build -t localhost/hmac-file-server:latest -f dockerenv/podman/Dockerfile.podman .
+podman run -d --name hmac-file-server \
+  -p 8888:8888 -p 9090:9090 \
+  -v ./config.toml:/app/config.toml:ro \
+  -v ./data:/data:rw \
+  localhost/hmac-file-server:latest -config /app/config.toml
+
+# Health verification
+curl -f http://localhost:8888/health && echo " - Server is healthy! ✅"
+```
+
+### Manual Setup: Paths, Ownership & Permissions
+
+When setting up Podman or Docker manually, proper path ownership is crucial:
+
+#### **Container User Configuration**
+- **Container User**: `appuser` (UID: 1011, GID: 1011)
+- **Security**: Non-root user for enhanced security
+- **Compatibility**: Works with both rootless and rootful containers
+
+#### **Required Directory Structure**
+```bash
+# Create base directory structure
+mkdir -p /opt/podman/hmac-file-server/{config,data,deduplication,logs}
+
+# Set proper ownership (CRITICAL for container access)
+# For Podman rootless:
+podman unshare chown -R 1011:1011 /opt/podman/hmac-file-server
+
+# For Docker or Podman rootful:
+chown -R 1011:1011 /opt/podman/hmac-file-server
+
+# Set proper permissions
+chmod 755 /opt/podman/hmac-file-server/{config,data,deduplication,logs}
+chmod 644 /opt/podman/hmac-file-server/config/config.toml  # Read-only config
+```
+
+#### **Path Mapping Reference**
+
+| Host Path | Container Path | Purpose | Required Permissions |
+|-----------|----------------|---------|---------------------|
+| `/opt/podman/hmac-file-server/config/config.toml` | `/app/config.toml` | Configuration file | `644` (read-only) |
+| `/opt/podman/hmac-file-server/data/` | `/data/` | File uploads/storage | `755` (read-write) |
+| `/opt/podman/hmac-file-server/deduplication/` | `/deduplication/` | Deduplication cache | `755` (read-write) |
+| `/opt/podman/hmac-file-server/logs/` | `/logs/` | Application logs | `755` (read-write) |
+
+#### **SELinux Labels (Important for RHEL/CentOS/Fedora)**
+```bash
+# Add SELinux labels for Podman volume mounts
+podman run -d --name hmac-file-server \
+  -v /opt/podman/hmac-file-server/config/config.toml:/app/config.toml:ro,Z \
+  -v /opt/podman/hmac-file-server/data:/data:rw,Z \
+  -v /opt/podman/hmac-file-server/deduplication:/deduplication:rw,Z \
+  -v /opt/podman/hmac-file-server/logs:/logs:rw,Z \
+  localhost/hmac-file-server:latest
+
+# Note: The `:Z` flag relabels content and should be used for private volumes
+# Use `:z` for shared volumes between multiple containers
+```
+
+#### **Common Ownership Issues & Solutions**
+
+**❌ Problem**: Container fails with permission errors
+```bash
+# Logs show: "permission denied: open /data/.write_test"
+```
+
+**✅ Solution**: Fix ownership and verify
+```bash
+# Fix ownership
+chown -R 1011:1011 /opt/podman/hmac-file-server
+
+# Verify ownership
+ls -la /opt/podman/hmac-file-server/
+# Should show: drwxr-xr-x 2 1011 1011
+
+# Test write permissions
+sudo -u "#1011" touch /opt/podman/hmac-file-server/data/test.txt
+# Should succeed without errors
+```
+
+**❌ Problem**: SELinux blocking container access  
+```bash
+# Logs show: "SELinux is preventing access"
+```
+
+**✅ Solution**: Correct SELinux labeling
+```bash
+# Option 1: Use :Z labels in volume mounts (recommended)
+-v /path/to/data:/data:rw,Z
+
+# Option 2: Set SELinux context manually
+sudo setsebool -P container_manage_cgroup on
+sudo restorecon -R /opt/podman/hmac-file-server
+```
+
+#### **Docker vs Podman Ownership Differences**
+
+| Scenario | Docker | Podman Rootless | Podman Rootful |
+|----------|--------|-----------------|----------------|
+| **Host UID** | 1011:1011 | 1011:1011 | 1011:1011 |
+| **Container UID** | 1011:1011 | 1011:1011 | 1011:1011 |
+| **Volume Ownership** | `chown 1011:1011` | `podman unshare chown 1011:1011` | `chown 1011:1011` |
+| **SELinux Labels** | `:Z` or `:z` | `:Z` or `:z` | `:Z` or `:z` |
+
+#### **Verification Commands**
+```bash
+# Check container user
+podman exec hmac-file-server id
+# Expected: uid=1011(appuser) gid=1011(appuser)
+
+# Check file permissions in container
+podman exec hmac-file-server ls -la /data /deduplication /logs
+# Expected: drwxr-xr-x appuser appuser
+
+# Verify write access
+podman exec hmac-file-server touch /data/permission-test
+# Should succeed without errors
+
+# Check configuration access
+podman exec hmac-file-server cat /app/config.toml | head -5
+# Should display config content
+```

+## Running with Podman
+
+Podman is a daemonless container engine that's often preferred in enterprise environments for enhanced security and rootless capabilities. HMAC File Server 3.2 provides complete Podman support with optimized deployment scripts.
+
+### Why Choose Podman?
+
+| Feature | Docker | Podman |
+|---------|--------|--------|
+| **Daemon** | Requires Docker daemon | Daemonless architecture |
+| **Root Access** | Requires root for Docker daemon | Can run completely rootless |
+| **Security** | Good, but daemon runs as root | Enhanced security, no privileged daemon |
+| **Systemd Integration** | Via Docker service | Native systemd integration |
+| **Pod Support** | Requires docker-compose or swarm | Native Kubernetes-style pods |
+| **Enterprise Use** | Popular in startups/mid-size | Preferred in enterprise environments |
+| **SELinux** | Basic support | Excellent SELinux integration |
+
+### Quick Start with Podman
+
+```bash
+# Clone repository
+git clone https://github.com/PlusOne/hmac-file-server.git
+cd hmac-file-server/dockerenv/podman
+
+# One-command deployment
+./deploy-podman.sh
+
+# Check status
+./deploy-podman.sh status
+
+# View logs
+./deploy-podman.sh logs
+```
+
+### Manual Directory & Permission Setup
+
+#### **Understanding Container Security Model**
+- **Container User**: `appuser` (UID: 1011, GID: 1011)
+- **Security Principle**: Never run containers as root (UID 0)
+- **Compatibility**: Works across different container runtimes and deployment modes
+
+#### **Step-by-Step Manual Setup**
+
+**Step 1: Create Directory Structure**
+```bash
+# Create organized directory layout
+export HMAC_BASE="/opt/podman/hmac-file-server"
+sudo mkdir -p ${HMAC_BASE}/{config,data,deduplication,logs}
+
+# Create subdirectories for uploads and duplicates
+sudo mkdir -p ${HMAC_BASE}/data/{uploads,temp}
+sudo mkdir -p ${HMAC_BASE}/deduplication/store
+sudo mkdir -p ${HMAC_BASE}/logs/{access,error,debug}
+```
+
+**Step 2: Set Ownership (CRITICAL)**
+```bash
+# For Podman Rootless (recommended)
+podman unshare chown -R 1011:1011 ${HMAC_BASE}
+
+# For Podman Rootful or Docker
+sudo chown -R 1011:1011 ${HMAC_BASE}
+
+# Alternative: Use numeric IDs to avoid user lookup issues
+sudo chown -R 1011:1011 ${HMAC_BASE}
+```
+
+**Step 3: Set Permissions**
+```bash
+# Directory permissions (executable for traversal)
+sudo chmod 755 ${HMAC_BASE}
+sudo chmod 755 ${HMAC_BASE}/{config,data,deduplication,logs}
+sudo chmod 755 ${HMAC_BASE}/data/{uploads,temp}
+sudo chmod 755 ${HMAC_BASE}/deduplication/store
+sudo chmod 755 ${HMAC_BASE}/logs/{access,error,debug}
+
+# Configuration file (read-only)
+sudo chmod 644 ${HMAC_BASE}/config/config.toml
+```
+
+**Step 4: Verify Ownership**
+```bash
+# Check ownership recursively
+ls -laR ${HMAC_BASE}
+
+# Expected output format:
+# drwxr-xr-x 2 1011 1011 4096 Dec 20 10:30 data
+# drwxr-xr-x 2 1011 1011 4096 Dec 20 10:30 deduplication  
+# drwxr-xr-x 2 1011 1011 4096 Dec 20 10:30 logs
+# -rw-r--r-- 1 1011 1011 1234 Dec 20 10:30 config/config.toml
+```
+
+#### **Container Volume Mapping**
+
+| Host Path | Container Mount | Access Mode | SELinux Label | Purpose |
+|-----------|-----------------|-------------|---------------|---------|
+| `${HMAC_BASE}/config/config.toml` | `/app/config.toml` | `ro` | `:Z` | Configuration file |
+| `${HMAC_BASE}/data/` | `/data/` | `rw` | `:Z` | File uploads |
+| `${HMAC_BASE}/deduplication/` | `/deduplication/` | `rw` | `:Z` | Dedup cache |
+| `${HMAC_BASE}/logs/` | `/logs/` | `rw` | `:Z` | Application logs |
+
+#### **Complete Manual Run Command**
+```bash
+# Build container image
+podman build -t localhost/hmac-file-server:latest -f dockerenv/podman/Dockerfile.podman .
+
+# Run with proper volume mounts and SELinux labels
+podman run -d --name hmac-file-server \
+  --security-opt no-new-privileges \
+  --cap-drop=ALL \
+  --read-only \
+  --tmpfs /tmp:rw,noexec,nosuid,size=100m \
+  -p 8888:8888 \
+  -p 9090:9090 \
+  -v ${HMAC_BASE}/config/config.toml:/app/config.toml:ro,Z \
+  -v ${HMAC_BASE}/data:/data:rw,Z \
+  -v ${HMAC_BASE}/deduplication:/deduplication:rw,Z \
+  -v ${HMAC_BASE}/logs:/logs:rw,Z \
+  localhost/hmac-file-server:latest -config /app/config.toml
+```
+
+### Troubleshooting Path & Permission Issues
+
+#### **Common Error: Permission Denied**
+```bash
+# Error in logs
+{"level":"error","msg":"failed to create directories: mkdir /data: permission denied"}
+```
+
+**Root Cause**: Incorrect ownership or missing directories
+
+**Solution**:
+```bash
+# Check current ownership
+ls -la ${HMAC_BASE}
+
+# Fix ownership (adjust command based on your setup)
+# For rootless Podman:
+podman unshare chown -R 1011:1011 ${HMAC_BASE}
+
+# For rootful Podman/Docker:
+sudo chown -R 1011:1011 ${HMAC_BASE}
+
+# Verify fix
+sudo -u "#1011" touch ${HMAC_BASE}/data/test-write
+rm ${HMAC_BASE}/data/test-write
+```
+
+#### **Common Error: SELinux Denial**
+```bash
+# Error in logs or journalctl
+SELinux is preventing access to 'write' on the file /data/test.txt
+```
+
+**Root Cause**: SELinux context not set for container volumes
+
+**Solution**:
+```bash
+# Option 1: Use :Z labels (recommended - private volumes)
+-v ${HMAC_BASE}/data:/data:rw,Z
+
+# Option 2: Use :z labels (shared volumes between containers)  
+-v ${HMAC_BASE}/data:/data:rw,z
+
+# Option 3: Set SELinux boolean (system-wide change)
+sudo setsebool -P container_manage_cgroup on
+
+# Option 4: Manual context setting
+sudo semanage fcontext -a -t container_file_t "${HMAC_BASE}(/.*)?"
+sudo restorecon -R ${HMAC_BASE}
+```
+
+#### **Common Error: User Namespace Issues**
+```bash
+# Error starting container
+Error: can't stat ${HMAC_BASE}/data: permission denied
+```
+
+**Root Cause**: User namespace mapping issues in rootless mode
+
+**Solution**:
+```bash
+# Check user namespace configuration
+cat /etc/subuid /etc/subgid | grep $USER
+
+# If missing, add mappings (requires root)
+sudo usermod --add-subuids 1000-65536 $USER
+sudo usermod --add-subgids 1000-65536 $USER
+
+# Restart user services
+systemctl --user restart podman
+
+# Use podman unshare for ownership
+podman unshare chown -R 1011:1011 ${HMAC_BASE}
+```
+
+#### **Verification & Testing Commands**
+
+```bash
+# Test 1: Verify container can access all paths
+podman exec hmac-file-server sh -c '
+  echo "=== Container User ==="
+  id
+  echo "=== Directory Access ==="
+  ls -la /app /data /deduplication /logs
+  echo "=== Write Test ==="
+  touch /data/write-test && echo "✅ Data write: OK" || echo "❌ Data write: FAILED"
+  touch /deduplication/dedup-test && echo "✅ Dedup write: OK" || echo "❌ Dedup write: FAILED"  
+  touch /logs/log-test && echo "✅ Log write: OK" || echo "❌ Log write: FAILED"
+  echo "=== Config Read Test ==="
+  head -3 /app/config.toml && echo "✅ Config read: OK" || echo "❌ Config read: FAILED"
+'
+
+# Test 2: External health check
+curl -f http://localhost:8888/health && echo "✅ HTTP Health: OK" || echo "❌ HTTP Health: FAILED"
+
+# Test 3: Metrics endpoint
+curl -s http://localhost:9090/metrics | grep -E "hmac_|go_|process_" | wc -l
+# Should return > 0 if metrics are working
+
+# Test 4: File upload simulation (requires auth)
+curl -X POST http://localhost:8888/upload \
+  -H "Authorization: Bearer your-token" \
+  -F "file=@test-file.txt" && echo "✅ Upload: OK" || echo "❌ Upload: FAILED"
+```
+
+#### **Advanced: Custom UID/GID Mapping**
+
+If you need different UIDs (e.g., for existing file ownership):
+
+```bash
+# Option 1: Rebuild container with custom UID
+podman build -t localhost/hmac-file-server:custom \
+  --build-arg USER_UID=1500 \
+  --build-arg USER_GID=1500 \
+  -f dockerenv/podman/Dockerfile.podman .
+
+# Option 2: Use --user flag (may have limitations)
+podman run --user 1500:1500 [other options] localhost/hmac-file-server:latest
+
+# Option 3: Host ownership adjustment
+sudo chown -R 1500:1500 ${HMAC_BASE}
+```
+
+#### **Docker vs Podman Ownership Differences**
+
+| Scenario | Docker | Podman Rootless | Podman Rootful |
+|----------|--------|-----------------|----------------|
+| **Host UID** | 1011:1011 | 1011:1011 | 1011:1011 |
+| **Container UID** | 1011:1011 | 1011:1011 | 1011:1011 |
+| **Volume Ownership** | `chown 1011:1011` | `podman unshare chown 1011:1011` | `chown 1011:1011` |
+| **SELinux Labels** | `:Z` or `:z` | `:Z` or `:z` | `:Z` or `:z` |
+
+### Podman Deployment Script Features
