# Docker Master Docker containers, images, and Compose stacks with expert guidance on networking, security hardening, and production-ready debugging. The Docker skill provides comprehensive expertise for managing containerized environments. It assists with creating optimized Dockerfiles , orchestrating multi-container applications via Docker Compose , and managing complex networking and volume configurations. It is designed to ensure build reliability, runtime stability, and production-grade security. ## How It Works 1 Step 1 Image Optimization Ensuring immutable builds by pinning versions and combining layers. 2 Step 2 Security Enforcement Implementing non-root users and resource limits by default. 3 Step 3 Troubleshooting Interpreting exit codes and inspecting container states to resolve failures quickly. ## Key Features - **Dockerfile Best Practices**: Guidance on multi-stage builds, layer caching, and minimizing image size. - **Compose Orchestration**: Expert management of service dependencies, health checks, and environment configurations. - **Infrastructure Management**: Setup and debugging of custom networks, named volumes, and bind mounts. - **Production Hardening**: Implementation of resource limits, log rotation, and security capabilities. - **Resource Cleanup**: Strategies for pruning dangling images, stopped containers, and unused volumes to reclaim disk space. ## Requirements This skill does not require any external API keys or cloud services. It operates directly with your local or remote Docker engine. ## Use Cases - **CI/CD Optimization**: Creating reliable, cached Docker builds that don't break between environments. - **Microservices Setup**: Orchestrating complex local development environments using Docker Compose. - **Production Debugging**: Identifying and fixing OOM kills, networking loops, or permission issues in running containers. - **Security Auditing**: Hardening existing Dockerfiles to meet enterprise security standards. ## Installation Install via: `npx clawhub@latest install docker`
