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
