How do you display all Docker container logs in real-time?

• A. docker logs [container_id]
• B. docker logs -a [container_id]
• C. docker logs -f [container_id]
• D. docker container logs [container_id]

Answer: (C)

The command that allows you to display all Docker container logs in real-time is the one that includes the `-f` flag, which stands for "follow." When this flag is used, it enables a continuous stream of logs from the specified container, meaning you can see new log entries as they are generated. This is particularly useful for monitoring applications in real-time, as it provides immediate feedback and insight into the running processes and their performance. The addition of the `-f` option effectively keeps the command active, appending new log messages as they occur. This is essential for developers and system administrators who want to troubleshoot issues or monitor application behavior without having to re-run the command manually. The other options, while they may display logs, do not provide the live, continuous feed that the `-f` option does. The command without `-f` will only show the logs generated up to that point and then exit, rather than keeping the session open to append further log entries.
