First, you need to know the process id, and then check if the launch command has significant info:
$ ps aux | grep $pid
Then check if the program path has any clue:
$ sudo ls -l /proc/$pid/exe
If not, try checking the current path of the execution:
$ sudo pwdx $pid
If nothing works, check the open files from that process:
$ sudo ps auxwe | grep $pid
Show docker container information:
$ for i in $(docker container ls --format "{{.ID}}"); do docker inspect -f '{{.State.Pid}} {{.Name}}' $i; done
