===============================================================================================================
|

Usage：sh 执行脚本.sh [update|start|stop|restart|remove|status|version|images]
|
||
update：更新镜像 会查询当前是否有.tar.gz的镜像文件，则将镜像加载到镜像列表，文件列表则为镜像名称，并删除镜像文件
|
||
start：启动服务 根据最新镜像版本启动当前服务程序
|
||
stop：停止服务 停止当前服务容器
|
||
restart：重启 停止当前服务容器，并删除容器，并以服务最新镜像拉起服务容器
|
||
remove：删除 删除当前服务容器，就算容器正在运行也会被强制删除
|
||
status：服务状态 查询当前服务是否在运行中，如果在运行则打印出当前运行容器信息
|
||
version：当前版本 查看当前容器使用的镜像版本
|
||
images：服务镜像版本列表 查看当前服务的镜像版本列表
