How to identify which docker container is consuming 100% CPU

• Open htop and press F6 and select PERCENT_CPU. Repeat until you’ve sorted descending by CPU consumption
• Now identify the PID (process ID) of the offending process consuming 100% CPU

• In our example, the offending PID is 8599
• Now run this command to find a list of the running docker container by PID:

docker inspect -f '{{.State.Pid}}, {{.Name}}' $(docker ps -q)

• Now identify the line with the PID, e.g.

8599, /wordpress-myblog-btronik_mariadb_1

Now you know which container is consuming 100% CPU.
