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

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{{.MemPerc}}" | sort -k 9 -n
