What is the primary purpose of Docker Compose?

• To manage single Docker containers.

A common use case for Docker Compose in a development environment is:

• Managing hundreds of microservices in a production cluster.

• Building a single, monolithic application container.

When using Compose for a multi-container application, how does Compose facilitate communication between services (e.g., a web app and a database)?

• By manually configuring IP addresses for each container.

• By automatically creating a default network and allowing services to resolve each other by their service names.

• By requiring all services to run on the host network.

• By installing a complex DNS server inside each container.

• It pauses all services without stopping them.

• It rebuilds all the images from scratch.

In a docker-compose.yml file, if you want a service to build its image from a local Dockerfile, which instruction would you use within that service's definition?
