실습 문제

(required) 사전에 [실습] 아코디언 카탈로그 & 파이프라인이 선행되어야 합니다.
사전 수행해야하는 실습 자료 : https://training.accordions.co.kr/docs/application/5_hands_on/5_2_practice2/

1. 생성한 catalog-usecase 디플로이먼트에 아래 설정대로 오토스케일을 설정합니다.

- Min Pods: 2
  Max Pods: 4
  오토스케일 기준: TPS
  TPS: 5

2. 생성한 HPA를 확인하세요.

3. 아래 예제 YAML을 토대로 부하 발생기 deployment를 배포한 뒤, 애플리케이션 모니터링(APM) 화면으로 전환하여 모니터링 합니다.

4. 부하 발생 후 오토스케일 되는지 확인합니다.

5. 생성한 HPA 리소스와 catalog-usecase 카탈로그를 삭제합니다.
