For Horizontal scaling in k8s, we need to create one service using k8s yaml file. This file will include all the required information. Below is the sample file which is used for auto-scaling. Below is the explanation of how auto scale will work for the sample file. Scale Up: If the current CPU utilization of the pods is 70%, the HPA will add more pods to bring the average utilization down towards 50%. Scale Down: If the current CPU utilization of the pods is 30%, the HPA will remove some pods to bring the average utilization up towards 50%.
