Docker Compose Multi-Container Orchestration
YAML Service Definitions, Dependencies & One-Command Environments
What You Will Master:
- Write multi-service Docker Compose YAML files
- Orchestrate full stacks with `docker compose up -d` and `docker compose down`
- Understand project-scoped default networks and volumes
1Why Docker Compose?
Running 5 separate microservices with individual `docker run` commands requires manually setting networks, volume mounts, and port flags for each one.
**Docker Compose** allows you to describe your entire multi-container architecture in a single declarative `compose.yaml` file and spin everything up with one command:
```bash
docker compose up -d
```
