Container Images Skill

Overview

Specialized skill for Docker and OCI container image development, optimization, and security. Provides expert capabilities for building production-ready container images.

Capabilities

Dockerfile Development

  • Analyze and optimize existing Dockerfiles
  • Create multi-stage build configurations
  • Implement build argument patterns
  • Design base image hierarchies
  • Handle platform-specific builds (multi-arch)

Image Optimization

  • Minimize image layer count and size
  • Optimize layer caching strategies
  • Implement .dockerignore patterns
  • Remove unnecessary dependencies
  • Use distroless/minimal base images

Security Scanning

  • Interpret vulnerability scan results (Trivy, Snyk, Grype)
  • Prioritize CVE remediation
  • Recommend secure base images
  • Implement image signing (Cosign, Notary)
  • Configure admission policies

Registry Operations

  • Push, pull, and tag images
  • Configure registry authentication
  • Implement image retention policies
  • Handle multi-registry strategies
  • Manage image manifests and indexes

Build Integration

  • Integrate with CI/CD pipelines
  • Configure build caching (BuildKit)
  • Implement remote builders
  • Handle secrets during builds
  • Set up automated builds

Target Processes

  • container-image-management.js - Container image lifecycle
  • security-scanning.js - Image vulnerability scanning
  • cicd-pipeline-setup.js - Build pipeline configuration
