What does the Docker command 'docker logs' do?

• A. It retrieves logs from a specified container
• B. It displays the status of a running container
• C. It builds an image with attached logs
• D. It removes old logs from the host

Answer: (A)

The command 'docker logs' is designed specifically to retrieve logs from a specified container. This command allows users to view the output of the container's processes, which is essential for debugging and monitoring the behavior of applications running within Docker containers. By accessing these logs, users can gain insights into how their applications are functioning and identify any errors or issues that may arise during execution. This command is particularly useful for troubleshooting because it can display logs in real-time, and users can specify various options to filter or format the log output as needed. Understanding how to utilize 'docker logs' is key for anyone managing Docker containers, as it provides visibility into the runtime characteristics and programmatic output of containerized applications.
