What is Docker Compose used for?
- ADefining and running multi-container applications using a single YAML file to configure all services, networks, and volumes
- BBuilding optimized Docker images by combining multiple Dockerfiles into a single multi-stage build pipeline
- COrchestrating containers across a cluster of machines with automatic scaling, load balancing, and failover
- DManaging Docker daemon configuration on multiple hosts by synchronizing registry credentials and settings
Why this is the answer
Compose simplifies orchestrating applications with multiple services (e.g. web + database + cache). One `docker compose up` replaces multiple `docker run` commands with all their flags.
