#1.创建目录 存在则跳过，不存在则创建

else
  echo "Sorry File " $dockerCatalogName "Already exist ！"

#2.进入docker 目录并下载jdk
#进入目录
echo "进入" $dockerCatalogName "目录"
cd $dockerCatalogName

#3.下载jdk 判断文件是否已下载，下载则跳过
if [ ! -f "jdk-8u212-linux-x64.tar.gz" ];then
  wget -P /$dockerCatalogName https://改成jdk路径/jdk-8u212-linux-x64.tar.gz

#4.创建 dockerFileName
if [ ! -f $dockerFileName ];then
	#dockerfile 不存在，直接创建创建
	echo "no dockerfile go create ."

#5.运行dockerfile
docker build -f /$dockerCatalogName/$dockerFileName -t $imagesName .

#6.创建
docker run -id -p 9000:9000 -p 9001:9001 --name=$containerName $imagesName /bin/bash
