How to Use

Examples

docker run -d -p 8080:80 -e NODE_ENV=prod nginx → service with port mapping and env var

docker run --name db -v /data:/var/lib/postgresql/data postgres:14 → service with named volume

docker run --network backend --restart always redis → service with custom network and restart policy

Best Practices

• Review the generated YAML before using it in production — some flags may need manual adjustment
• Add health checks, resource limits, and logging configuration that docker run doesn't capture
• Use named volumes instead of bind mounts for better portability
• Consider adding a .env file for environment variables instead of hardcoding them
• Test the generated compose file with docker-compose config before deploying

Common Mistakes

• Forgetting to map all ports — complex port mappings may not parse correctly
• Not adding health checks in the compose file that were implicit in the docker run setup
• Assuming all docker run flags have direct compose equivalents
• Using the generated YAML without reviewing it for correctness
• Missing environment variables that were passed via --env-file instead of -e
