Challenge

Open Three Terminals and Three Sessions to the Lab Server
1. Open three terminal sessions.
2. In each one, log in to the server using the credentials provided:
```
ssh cloud_user@<PUBLIC_IP_ADDRESS>
```

Challenge

Run Two Python Containers with Set Limits 50% CPU and 500M RAM

sudo docker run -it --rm --cpus="0.5" --memory=500m docker.io/python

sudo docker run -it --rm --cpus="0.5" --memory=500m docker.io/python

Challenge

Run Tests to See Your Resource Limits Take Effect

In each container, run this code and observe the resource usage with htop in the third terminal session:

import threading

def test():
  while True:
    1000*1000

threading.Thread(target=test).start()
threading.Thread(target=test).start()
threading.Thread(target=test).start()
threading.Thread(target=test).start()
threading.Thread(target=test).start()
