Docker Workflow (source: AutumnsGrove)

Overview

Docker containerization streamlines development, testing, and deployment by packaging applications with their dependencies into portable, reproducible containers. This skill guides you through professional Docker workflows from development to production.

Core Capabilities

• Multi-stage builds: Separate build and runtime dependencies for optimal image size
• Docker Compose orchestration: Manage multi-container applications with networking and dependencies
• Image optimization: Reduce image size by 50-90% through best practices
• Development workflows: Hot-reload, volume mounting, and environment-specific configs
• Debugging tools: Container inspection, health checks, and troubleshooting utilities
• Production readiness: Security hardening, health checks, and deployment strategies

When to Use This Skill

Activate when:

• Containerizing a new application
• Setting up development environments with Docker
• Creating production-ready Docker images
• Orchestrating multi-container applications
• Debugging container issues
• Optimizing Docker builds and images

Workflow Phases

Phase 1: Initial Setup

Create .dockerignore

Exclude unnecessary files from build context:

node_modules/
__pycache__/
*.pyc
.git/
.env
*.log
