從k8s導(dǎo)出資源后，需要刪除yaml里面的垃圾數(shù)據(jù)，需要批量改namespace名稱，deploy中的鏡像地址，改ingress的域名等等信息
通過如下腳本實現(xiàn)：

#!/bin/bash
# set -x

# 鏡像環(huán)境變量之項目環(huán)境變量標(biāo)簽
itemEnv=dev
# 項目域名
## 項目主域名
mainDoname="xiaojinguang.com"
## 項目前端域名二級域名頭
webDoname="side"
## 項目后端域名二級域名頭
apiDoname="api"
# 項目二級域名中的環(huán)境變量標(biāo)簽（導(dǎo)出時）：比如：dev,test,正式為空，同上面變量組合為：apidev.xiaojinguang.com,apitest.xiaojinguang.com
oldName=""
# 項目二級域名中的環(huán)境變量標(biāo)簽（需變更后的）
repName="dev"
# namespace
## 變更后的命名空間名稱
NSnew=jintest
## change image
### 從k8s集群獲取deploy中容器image數(shù)據(jù)的命名空間名稱
NS=jindev
# docker 鏡像倉庫的項目名稱
PROJECK=xiao
# 指定獲取deploy中容器image數(shù)據(jù)時，連接k8s集群用的kubectl認(rèn)證文件
configFile=~/.kube/config
