kubernetes之namespace资源导出02

从k8s导出资源后，需要删除yaml里面的垃圾数据，需要批量改namespace名称，deploy中的镜像地址，改ingress的域名等等信息
通过如下脚本实现：

#!/bin/bash
# set -x

# 镜像环境变量之项目环境变量标签
itemEnv=dev
# 项目域名
## 项目主域名
mainDoname="xiaojinguang.com"
## 项目前端域名二级域名头
webDoname="side"
## 项目后端域名二级域名头
apiDoname="api"
# 项目二级域名中的环境变量标签（导出时）：比如：dev,test,正式为空，同上面变量组合为：apidev.xiaojinguang.com,apitest.xiaojinguang.com
oldName=""
# 项目二级域名中的环境变量标签（需变更后的）
repName="dev"
# namespace
## 变更后的命名空间名称
NSnew=jintest
## change image
### 从k8s集群获取deploy中容器image数据的命名空间名称
NS=jindev
# docker 镜像仓库的项目名称
PROJECK=xiao
# 指定获取deploy中容器image数据时，连接k8s集群用的kubectl认证文件
configFile=~/.kube/config
