Docker save/load lose original image repository/name/tag
docker, docker-image
Solution
Use
docker save -o filename.tar <repo>:<tag>
The command `docker save <image id>` removes the repository and tag names.
To solve this, use `docker save <repo>:<tag>` it will keep the repository and tag name in the saved file. For example:
docker save -o ubutu-18.04.tar ubuntu:18.04
Problem
I'm using Docker 1.12.6. I have pulled an image from the Docker registry. I have exported the images as tar files using the `docker save` command. I removed the original image and container and loaded the exported image using `docker load -i myImage.tar`. Now, when running `docker images` I notice my image have lost its repository/tag information: ``` REPOSITORY TAG IMAGE ID CREATED SIZE <none> <none> 5fae4d4b9e02 8 weeks ago 581.3 MB ``` Why does it have this behavior and how do I keep the original image name?
