process 수정
process에 ulimit 설정으로 해결되지 않는 것으로 보임

- runtime 수정(docker, containerd 설정 /etc/docker/datmon.json, containerd 는 없는 것으로 보임)
- /etc/security/limits.conf 수정 -> 리붓, 적용을 안해봐서 파일 수정만으로는 일단 안되는 것 확인

 container
initContainer 로 fs.inotify.max_user_instances 값을 128->512 변경으로 성공

initContainer:
 - name: init
   image: docker.io/busybox:1.33
   command:
     - sh
     - -c
     - sysctl -w fs.inotify.max_user_instances=512
