description	Build and run Docker containers for the ResumeAI application.

Docker Build Skill

This skill provides commands for building and running Docker containers for the ResumeAI application.

Capabilities

• Build Images: Build frontend and backend Docker images
• Run Containers: Run application containers
• Docker Compose: Use docker-compose for full stack
• Local Development: Run development environment with hot reload
• Container Management: Start, stop, and manage containers

Prerequisites

• Docker is installed
• Docker Compose is installed
• Ports 3000, 5432, 8000 are available (or configured differently)

Usage

Build Docker Images

# Build frontend image
docker build -t resumeai-frontend:latest .

# Build backend image
docker build -t resumeai-backend:latest -f Dockerfile.backend .

# Build all images
docker-compose build

Run Containers

# Run frontend
docker run -p 3000:3000 resumeai-frontend:latest

# Run backend
docker run -p 8000:8000 -e DATABASE_URL=sqlite:///resumeai.db resumeai-backend:latest

Docker Compose

# Start all services
docker-compose up

# Start in background
docker-compose up -d

# View logs
docker-compose logs -f

# Stop services
docker-compose down

Local Development with Docker

# Use local development compose file
docker-compose -f docker-compose.local.yml up

# Or with override
docker-compose -f docker-compose.yml -f docker-compose.local.yml up

Useful Docker Commands

# List running containers
docker ps

# List all containers
docker ps -a

# View container logs
docker logs <container_id>

# Execute command in container
docker exec -it <container_id> bash

# Remove unused images
docker image prune

# Remove stopped containers
docker container prune

Docker Compose Services

The project typically defines:

• frontend - React frontend application
• backend - FastAPI backend
• postgres - PostgreSQL database (production)
• redis - Redis cache (production)

Environment Variables

Create .env.docker or .env.local with:

DATABASE_URL=postgresql://user:pass@postgres:5432/resumeai
REDIS_URL=redis://redis:6379
API_URL=http://localhost:8000

Building for Production

# Build production images
docker build -t resumeai-frontend:latest --target production .

# Or use multi-stage build
docker build -t resumeai-backend:latest .

Tips

• Use docker-compose up --build to rebuild after code changes
• Use volumes for development to enable hot reload
• Check .dockerignore to exclude unnecessary files
• Use docker system prune to clean up disk space
• Use specific tags for images in production (not latest)
