☁️ Free practice test question from: Container Orchestration (KCNA)

Docker Compose is specifically designed to help developers define and manage multi-container Docker applications. By using a declarative YAML file (docker-compose.yml), you can specify all the services, networks, and volumes your application needs. This setup simplifies the process of orchestrating multiple containers, making it easier to develop, test, and run complex applications on a single host.

*****

A) This describes tools like Docker Swarm or Kubernetes, which are designed for cluster management and orchestration across multiple machines. Docker Compose focuses on a single host.

B) While Compose simplifies multi-container setups for development and testing, its primary function isn't solely focused on containerizing applications (that's Docker's job). Compose orchestrates existing containerized services.

C) This is more related to Dockerfiles, build processes, and image optimization techniques. Compose uses pre-built images or images defined in Dockerfiles but doesn't primarily focus on optimizing the build process itself.
