shell脚本导出k8s资源文件

#!/bin/bash

useage(){
    echo "useage:"
    echo "  dump_k8s_yaml.sh DUMPDIR [NAMESPACE]"
}

if [ $# -lt 1 ];then
    useage
    exit
fi

NS=$2
dumpDir=$1

resourceList=(
deploy
services
endpoints
ingress
secrets
pvc
cm
)

printList(){
  for aa in ${resourceList[@]};
  do
    aList=$(kubectl  -n $NS get $aa |grep -v NAME  |awk '{print $1}')
    if [ ! "${aList[*]}"x == "x" ];then
      [ -d $dumpDir/$aa ] || mkdir -p $dumpDir/$aa
      for i in $aList;
      do
        echo $aa $i
        kubectl -n $NS get $aa $i -o yaml > $dumpDir/$aa/$i.yaml
      done
    fi
  done
}

# create namespaces yaml
if [ ! -d $dumpDir ];then
  mkdir -p $dumpDir
fi


kubectl  get namespaces $NS -o yaml > $dumpDir/namespaces.yaml

# create pv yaml
pvList=$(kubectl get pv |grep "$NS/" |awk '{print $1}')
if [ ! "${pvList[*]}"x == "x" ];then
  [ -d $dumpDir/pv ] || mkdir -p $dumpDir/pv
  for i in ${pvList[@]}
  do
    echo pv $i
    kubectl get pv $i -o yaml > $dumpDir/pv/$i.pv.yaml
  done
fi

printList

使用用法：./dum_k8s_yaml $Dir $NAMESPACE

./dump_k8s_yaml ./dmp dmp

打印日志信息如下：

[root@kubernetes1 opt]# ./dump_k8s_yaml.sh ./dmp dmp
