Nodegroup Bootstrap Override For Custom AMIs

/etc/eks/bootstrap.sh 에 부트스트랩 관련된 shell파일이 있음
이 쉘파일을 실행할때 해당 값을 넣어줘야만, 제대로 노드그룹이 만들어짐.

필수적인건 custom ami 값이나, 노드 이름 같은 것들? 필요한거같음.

    overrideBootstrapCommand: |
      #!/bin/bash

      source /var/lib/cloud/scripts/eksctl/bootstrap.helper.sh

      # Note "--node-labels=${NODE_LABELS}" needs the above helper sourced to work, otherwise will have to be defined manually.
      /etc/eks/bootstrap.sh ${CLUSTER_NAME} --container-runtime containerd --kubelet-extra-args "--node-labels=${NODE_LABELS}"
