-1. Create a Deployment named `nginx:1.23.4` with 1 replica. The Pod template of the Deployment should use container image `nginx:1.23.4`, set the CPU resource request to 0.5, and the memory resource request/limit to 500Mi.

 2. Create a HorizontalPodAutoscaler for the Deployment named `nginx-hpa` that scales to minium of 3 and a maximum of 8 replicas. Scaling should happen based on an average CPU utilization of 75%, and an average memory utilization of 60%.
-3. Inspect the HorizontalPodAutoscaler object and identify the currently-utilized resources. How many replicas do you expect to exist?
