# Containerization Assistant Skill

Assists in containerizing applications by generating Dockerfiles, optimizing images, and configuring container deployments.

## Purpose

Enable application containerization for:
- Dockerfile generation
- Multi-stage build optimization
- Base image selection
- Dependency packaging
- Security scanning

## Capabilities

### 1. Dockerfile Generation
- Generate from application analysis
- Support multiple languages
- Include best practices
- Handle build dependencies

### 2. Multi-Stage Build Optimization
- Separate build and runtime
- Minimize image size
- Cache build layers
- Optimize build time

### 3. Base Image Selection
- Recommend appropriate base images
- Balance size vs features
- Consider security updates
- Handle distroless options

### 4. Dependency Packaging
- Bundle application dependencies
- Handle native extensions
- Configure build tools
- Manage versions

### 5. Health Check Configuration
- Add health checks
- Configure readiness probes
- Set up liveness probes
- Define startup probes

### 6. Security Scanning
- Scan for vulnerabilities
- Check base image security
- Identify exposed secrets
- Review permissions
