# Distroless Docker Options for APRS.me
This document compares different distroless approaches for containerizing the APRS.me Elixir/Phoenix application.
## Current Setup vs Distroless Options
### Current Setup (`Dockerfile`)
- **Base Image**: `debian:bullseye-slim` (~80MB)
- **Security**: Good (non-root user, hardened)
- **Attack Surface**: Moderate (full Debian with package manager)
- **Debugging**: Easy (shell access, package manager)
- **Compatibility**: Excellent
### Option 1: Simple Distroless (`Dockerfile.distroless-simple`)
- **Base Image**: `gcr.io/distroless/cc-debian11:nonroot` (~20MB)
- **Security**: Excellent (no shell, no package manager)
- **Attack Surface**: Minimal
- **Debugging**: Difficult (no shell access)
- **Compatibility**: Good for most Elixir applications
- **Recommended**: ✅ **BEST STARTING POINT**
### Option 2: Custom Library Distroless (`Dockerfile.distroless`)
- **Base Image**: `gcr.io/distroless/base-debian11:nonroot` (~15MB)
- **Security**: Excellent
- **Attack Surface**: Minimal
- **Debugging**: Very difficult
- **Compatibility**: May require fine-tuning
- **Complexity**: High (manual library management)
### Option 3: Static Distroless (`Dockerfile.distroless-static`)
- **Base Image**: `gcr.io/distroless/static-debian11:nonroot` (~2MB)
- **Security**: Maximum
- **Attack Surface**: Absolute minimum
- **Debugging**: Nearly impossible
- **Compatibility**: **May not work** with Erlang/OTP
- **Recommended**: ❌ **NOT RECOMMENDED** for Elixir
## Recommended Migration Path
### Phase 1: Test Simple Distroless
1. Use `Dockerfile.distroless-simple`
2. Test all application functionality
3. Monitor for any runtime issues
4. Verify external dependencies work (database, APIs)
### Phase 2: Optimize (if needed)
1. If Phase 1 works perfectly, you're done!
2. If you need smaller images, consider custom library approach
3. Profile which libraries are actually needed
## Key Benefits of Distroless
### Security Improvements
- **No shell access**: Eliminates shell-based attacks
- **No package manager**: Cannot install malicious packages
- **Minimal attack surface**: Only your application + runtime
- **Reduced CVEs**: Fewer components = fewer vulnerabilities
- **Immutable**: Cannot be modified at runtime
### Operational Benefits
- **Smaller images**: Faster pulls, less storage
- **Faster startup**: Less to initialize
- **Better compliance**: Meets strict security requirements
- **Supply chain security**: Google-maintained base images
## Potential Challenges
### Debugging Difficulties
```bash
# This won't work in distroless:
docker exec -it container /bin/bash
# Use this instead:
docker run --rm -it --entrypoint="" your-image:tag /app/bin/server remote
```
### Limited Troubleshooting
- No shell for investigating issues
- Must rely on application logs
- Consider adding detailed logging/metrics
### Dependency Issues
- Some NIFs might need additional libraries
- SSL/TLS certificates need careful handling
- Time zones might not be available
## Testing Checklist
Before switching to distroless, verify:
- [ ] Application starts successfully
- [ ] Database connections work
- [ ] Phoenix LiveView functions
- [ ] Asset serving works
- [ ] SSL/HTTPS connections work
- [ ] External API calls succeed
- [ ] WebSocket connections work
- [ ] Health checks pass
- [ ] Graceful shutdown works
- [ ] Logging outputs correctly
## Build Commands
```bash
# Test simple distroless version
docker build -f Dockerfile.distroless-simple -t aprs:distroless-simple .
# Compare image sizes
docker images | grep aprs
# Test functionality
docker run -p 4000:4000 aprs:distroless-simple
```
## Rollback Plan
If distroless causes issues:
1. Keep current `Dockerfile` as `Dockerfile.debian`
2. Switch CI/CD back to Debian version
3. Investigate specific compatibility issues
4. Gradually migrate features
## Conclusion
**Recommendation**: Start with `Dockerfile.distroless-simple`
This provides:
- Significant security improvements
- Manageable complexity
- Good compatibility with Elixir/Phoenix
- Easy rollback if needed
The `gcr.io/distroless/cc-debian11:nonroot` image includes the C runtime libraries that Erlang/OTP requires, making it the most compatible distroless option for Elixir applications.

# System Dependency Updates for APRS.me Docker Image
This document outlines strategies for keeping system dependencies updated in the APRS.me Docker image without modifying the existing Dockerfile, which could potentially break the build process.
## Current Challenges
The Dockerfile builds successfully but maintaining up-to-date system dependencies is important for security. Standard approaches like adding `unattended-upgrades` or using `--security` flags with `apt-get` have proven problematic in our build environment.
## Recommended Approaches
### 1. Regular Rebuilds
The most reliable way to keep system dependencies updated is through regular rebuilds:
```bash
# Rebuild the Docker image with latest base image and dependencies
docker build --no-cache --pull -t aprs:latest .
```
Key flags:
- `--no-cache`: Forces all layers to be rebuilt, including running `apt-get update` and `apt-get upgrade`
- `--pull`: Ensures the latest version of the base image is used
### 2. Base Image Updates
Periodically update the base image version in the Dockerfile:
```diff
- ARG DEBIAN_VERSION=bullseye-20250520-slim
+ ARG DEBIAN_VERSION=bullseye-20250615-slim
```
The Debian team regularly releases updated images with security patches.
### 3. CI/CD Integration
Automate the update process:
1. Set up a weekly GitHub Actions workflow to:
- Build the image with `--no-cache --pull`
- Run security scans with Trivy
- Create a PR if updates are needed
2. Include base image version checks:
```yaml
- name: Check for newer base image
run: |
# Logic to check for newer base image versions
# Create PR if newer version available
```
### 4. Security Scanning
Regularly scan for vulnerabilities:
```bash
# Install Trivy
brew install aquasecurity/trivy/trivy # macOS
# or appropriate command for your OS
# Scan the image
trivy image aprs:latest
```
### 5. Manual Update Script
```bash
#!/bin/bash
# update-deps.sh
# Pull latest base image
docker pull debian:$(grep 'DEBIAN_VERSION=' Dockerfile | cut -d'=' -f2 | tr -d '"')
# Rebuild with latest dependencies
docker build --no-cache --pull -t aprs:latest .
# Scan for vulnerabilities
if command -v trivy &> /dev/null; then
trivy image aprs:latest
fi
echo "Image rebuilt with latest dependencies"
```
## Deployment Strategy
1. Rebuild images at least weekly
2. Deploy updated images after testing
3. Monitor security advisories for critical updates
4. Perform out-of-band updates for critical CVEs
## Monitoring
1. Set up alerts for high/critical vulnerabilities
2. Subscribe to security mailing lists for Debian and key packages
3. Use image scanning in your container registry
By following these approaches, you can maintain up-to-date system dependencies without modifying the Dockerfile in ways that might break the build process.
