how to copy file from docker container to local host
https://stackoverflow.com/questions/22049212/copying-files-from-docker-container-to-host
docker cp :/file/path/within/container /host/path/target
$ sudo docker cp goofy_roentgen:/out_read.jpg .
如何保存image
You will need to save the Docker image as a tar file:
docker save -o <path for generated tar file> <image name>
Then copy your image to a new system with regular file transfer tools such as cp, scp or rsync(preferred for big files). After that you will have to load the image into Docker:
docker load -i <path to image tar file>
PS: You may need to sudo all commands.
EDIT: You should add filename (not just directory) with -o, for example:
docker save -o c:/myfile.tar centos:16
