What is the command to see the resource usage of containers?

• A. docker info
• B. docker stats
• C. docker status
• D. docker usage

Answer: (B)

The command to see the resource usage of containers is "docker stats." This command provides real-time data about the performance of running containers, including CPU usage, memory usage, network I/O, and block I/O. It helps users monitor the performance of individual containers or all containers at a glance, allowing for effective management of resources and troubleshooting of performance issues. Other choices do not serve this specific purpose. "docker info" gives a detailed summary of the Docker environment, including the number of containers, images, and other general system information, but it does not provide resource usage details for individual containers. "docker status" is not a valid Docker command; status checks are usually integrated into other commands or can be checked via logs. "docker usage" is also not a command recognized in Docker CLI, thus it does not apply for checking resource utilization.
