What is the purpose of the docker stats command?

The docker stats command is used to display real-time resource usage of Docker containers, including CPU usage, memory usage, network I/O, and more. By running the docker stats command, you can monitor the resource consumption of running Docker containers, helping you identify problematic containers or monitor container performance.

Here are some common options for the docker stats command:

1. –all flag: display all containers, including those that are stopped.
2. –specify the output format using the “–format” flag, for example, you can use “–format “table {{.Container}}\t{{.CPUPerc}}” to output the specified information in a tabular format.
3. CONTAINER [CONTAINER…]: specify the name or ID of one or more containers to query.

It is important to note that the ‘docker stats’ command by default continuously outputs the resource utilization of the current container, you can use Ctrl + C to stop this continuous output.
