apiVersion: apps/v1
kind: Deployment

다음 mongo 이미지를 사용하여 업데이트와 롤백을 실행하라.
1. 모든 revision 내용은 기록돼야 한다.
2. mongo:4.2 이미지를 사용하여 deployment를 생성하라.
✓ Replicas: 10 ✓ maxSurge: 50%
✓ maxUnavailable: 50%
3. mongo:4.4 롤링 업데이트를 수행하라.
4. mongo:4.2로 롤백을 수행하라.

kubectl create deploy --image mongo:4.2 mongo-deploy --dry-run=client -o yaml > mongo-deploy.yml
kubectl create -f mo --record=true
kubectl set image deploy mongo-deploy mongo=mongo:4.4 --record=true
kubectl rollout history deploy mongo-deploy
kubectl rollout undo deploy mongo-deploy --to-revision=1
