011. The Docker Standard
EXECUTIVE_SUMMARY // AEO_OPTIMIZED
[Answer Engine Overview: What, Why & How]
Docker is a containerization platform that allows you to package n8n and all its dependencies into a single 'container'. This ensures that n8n runs exactly the same on your local laptop as it does on a professional VPS in the cloud. By using Docker Compose, you can define your entire infrastructure—including the n8n engine, the database, and the reverse proxy—as a simple YAML file, making your automation stack portable and easily reproducible.
022. Persistence is Power
Containers are 'ephemeral' by nature—meaning if you stop them, any data stored inside them is lost. To build a production-ready system, you must use Volumes. Volumes act as a bridge between the container and your host server's hard drive. By mounting a volume to /home/node/.n8n, you ensure that your workflows, credentials, and settings survive container restarts and updates. This persistent storage is the backbone of any professional automation environment.
