The Horizontal Pod Autoscaler with an Online Calendar for Kubernetes

Abstract
Kubernetes is free distribution software for managing containers or Pods. It has a function to support the basic needs for developers and system administrators as well. However, the automatic scaling of Pods based on the horizontal pod autoscaler is a slow to response. This is caused by the process of waiting for the load to appear in the system and then adding resources, and the container preparation time causes a slow response from the unavailable time interval. In this research, developed the Kubernetes system to be able to prepare Pods in advance via an online calendar. The software has a feature to read the schedule from the online calendar and send it to control the Kubernetes resources via the MQTT protocol. This includes the number of users and the appointment date. When the system receives the information, it will automatically expand the Pods according to the online calendar appointments. Experiments have shown that once the appointment is due, the system will automatically begin creating a Pods in less than 10 minutes.
