原因是：redis.tar压缩包出现了问题，换个docker的redis.tar的压缩包吧。
顺便从网上找几个同类问题可能的解决方案供参考，我是没用过，我这边出现这个问题确实是包在保存途中出现问题了。毕竟像系统镜像类的都会出问题。

Today I face an error when I was trying to import an image by using following steps,

Switch to image directory path,
1
cd docker/directory/image-path
Then run load command to import docker image in my system,
1
cat docker_custom_image.tar | docker load
After running load command I was getting an error,
“open /var/lib/docker/tmp/docker-import-622414428/bin/json: no such file or directory”

Then a bit searching and research I found few solutions to import the image,

You can fix this issue by creating the tmp folder inside /var/lib/docker/.
(In my case this solution doesn’t work so I made a bit more research and find the solution.)
I use below command in order to import the image.
1
cat docker_custom_image.tar | docker import - custom_docker/image
This ends up with the image showing up in

1
docker images

So this is how I found the solution to fix this issue but there is a question in everyone’s mind that why I was getting this issue?

It is because I was using docker load command to import image export by docker export command.

1
cat image-file |docker load
Would only work if the image is created as a layered docker image, not as a tar ball.

Basically correct way to import the image,

Use docker import for image exported by docker export.

Use docker load for image exported by docker save.
