How can you check the status of services in a Docker Compose application?

• A. docker-compose status
• B. docker-compose check
• C. docker-compose ps
• D. docker-compose info

Answer: (C)

To check the status of services in a Docker Compose application, the command `docker-compose ps` is the appropriate choice. This command provides a detailed list of all services defined in the `docker-compose.yml` file, displaying their current state which includes whether they are running, stopped, or in some other state. By utilizing `docker-compose ps`, users can easily monitor the health and status of individual containers managed by Docker Compose. It shows essential information such as the container ID, names, and their corresponding statuses, making it a vital tool for troubleshooting and managing multi-container Docker applications. Other options, while they may sound relevant, do not serve this specific purpose: "docker-compose status" and "docker-compose check" do not exist as commands in Docker Compose, and "docker-compose info" focuses on the overall configuration details rather than the status of individual services or containers. Thus, `docker-compose ps` stands out as the correct command for checking service statuses.
