Which command is used to view the logs of a container?

The command to view the logs of a container is indeed "docker logs [container_id]." This command retrieves and displays the log output from a specified container identified by its container ID or name. Logs are crucial for debugging and monitoring the behavior of applications running inside containers, as they provide insights into the running processes, errors, and other significant runtime events.

Using the correct format of this command allows users to effectively trace issues and understand the application flow, making it a vital tool in managing containerized applications. The other choices do not represent valid Docker commands for accessing logs, as they either do not exist or are not suited for this specific task.
