Sort by memory usage in docker stats

Question

Is there a way to display the docker stats sorted by memory usage of the containers?

I am using the following command to display the container with their names and I want to sort the result by memory usage.

docker stats --format "table {{.Name}}\t{{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}"

The unsorted result is the following.

NAME                                                                   CONTAINER           CPU %               MEM USAGE / LIMIT

Answer 1

docker stats --no-stream --format "table {{.Name}}\t{{.Container}}\t{{.MemUsage}}" | sort -k 3 -h

Commands sort only by memory

Answer 2

To sort by Mem Usage field you can use the following command:

GNU/Linux:

docker stats --no-stream --format "table {{.Name}}\t{{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}" | sort -k 4 -h

MacOS:

docker stats --no-stream --format "table {{.Name}}\t{{.Container}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.M‌​emPerc}}" | sort -k 9 -n
