To use script to show cpu info of host machine from docker container you need to run command:

docker run --rm $(docker build -q .) cpu

or for memory info

docker run --rm $(docker build -q .) mem

If you already have installed docker-compose, you have to choose correct command inside docker-compose.yml like:

command: cpu

or

command: mem

and run container:

docker-compose up

• NOTE: For the first time, it takes a little bit times to build docker image
