이 명령어를 잘 이용하면 각 서비스에 대한 yaml파일들을 백업할 수 있다.
#!/bin/sh
DIR=/k8s-bak/resouruces # 경로 입력
mkdir -p
for NS in $(kubectl get ns --no-headers | awk '{ print $1 }') # 모든 Namespace 조회
do
mkdir -p ${DIR}/${NS} # 각 Namespace 별 폴더 생성
for RESOURCE in $(kubectl api-resources --no-headers | awk '{ print $1 }') # 리소스 조회
do
kubectl get ${RESOURCE} -n ${NS} -o yaml > ${DIR}/${NS}/${RESOURCE}.yaml # YAML 백업
