执行Docker保存和加载功能的脚本（已试用）：

Docker保存：

#!/bin/bash

#files will be saved in the dir 'Docker_images'
mkdir Docker_images
cd Docker_images
directory=`pwd`
c=0
#save the image names in 'list.txt'
doc= docker images | awk '{print $1}' > list.txt
printf "START \n"
input="$directory/list.txt"
#Check and create the image tar for the docker images
while IFS= read -r line
do
     one=`echo $line | awk '{print $1}'`
     two=`echo $line | awk '{print $1}' | cut -c 1-3`
     if [ "$one" != "<none>" ]; then
             c=$((c+1))
             printf "\n $one \n $two \n"
             docker save -o $two$c'.tar' $one
             printf "Docker image number $c successfully converted:   $two$c \n \n"
     fi
done < "$input"

Docker加载：

#!/bin/bash

cd Docker_images/
directory=`pwd`
ls | grep tar > files.txt
c=0
printf "START \n"
input="$directory/files.txt"
while IFS= read -r line
do
     c=$((c+1))
     printf "$c) $line \n"
     docker load -i $line
     printf "$c) Successfully created the Docker image $line  \n \n"
done < "$input"

您可以使用sshfs：

$ sshfs user@ip:/<remote-path> <local-mount-path>
$ docker save <image-id> > <local-mount-path>/myImage.tar

对于容器文件系统的扁平导出，请使用；

docker导出CONTAINER_ID>my_CONTAINER.tar

使用cat my_container.tar | docker import-导入所述图像。

要将映像保存到任何文件路径或共享NFS位置，请参阅以下示例。

通过执行以下操作获取图像id：

docker images

假设您有一个id为“矩阵数据”的图像。

使用id保存图像：

docker save -o /home/matrix/matrix-data.tar matrix-data

将图像从路径复制到任何主机。现在使用以下方法导入本地Docker安装：

docker load -i <path to copied image file>

要将图像从本地Docker安装传输到minikube VM：

docker save <image> | (eval $(minikube docker-env) && docker load)
