Docker: save the running docker container as a docker image and save it to the local tar package "only verify the packaging part"

1. Save the running docker container as a docker image and save it to a local tarball

1、docker commit <容器id> <镜像名>:<tag>     ---- 将容器保存成镜像，tag比如说latest
 
保存后 docker images 便可以看到镜像
 
2、docker save -o <tar包名>.tar <镜像名>:<tag>      ---- 将镜像保存为.tar文件，默认保存在当前目录

2. Import the docker image from the tar package

1、docker load -i <tar包名>.tar     ---- 从 tar 包导入镜像
 
导入镜像后，通过 docker images 便可看到导入的镜像。
 
2、docker run -itd -p <本地端口>:<容器端口> <镜像名>:<tag>    ---- 通过镜像起容器

Case "save to tar package only"
