What to do if the image cannot be found after docker load

The reason why the image cannot be found after docker load is because the IMAGE ID is used when exporting the image save, and the image name is not used, so it will not be displayed. The solution is to re-execute "docker save -o csctbb. com/hadoop:3.3.0 >..." is enough.

The operating environment of this article: centos8 system, Docker 20.10.11, Dell G3 computer.

What should I do if the image cannot be found after docker load?

docker load -i cannot see the image after importing

[root@centos8 ~]# docker images                 
REPOSITORY          TAG        IMAGE ID       CREATED         SIZE
csctbb.com/hadoop   3.3.0      084faab5baec   7 hours ago     1.68GB
centos              8.1.1911   470671670cac   14 months ago   237MB
kubeguide/hadoop    latest     e0af06208032   4 years ago     830MB

[root@centos8 ~]# docker save 084faab5baec > csctbb.com-hadoop.tar

Problem:

docker load -i After importing, there is no prompt for success , and no error is reported, docker images cannot see the imported image?

As above, my image has a name and tag

Explanation:

This is because the IMAGE ID is used when exporting the image save , the image name is not used, so it will not be displayed.

Use the following method:

 docker save -o csctbb.com/hadoop:3.3.0 > csctbb.com-hadoop.tar

Just import it again

I use containerd here ctr test, the principle is the same, the difference is the command method

[root@ck8s2 ~]# ctr image import csctbb.com-hadoop.tar 
unpacking csctbb.com/hadoop:3.3.0 (sha256:6198b39f874b8c6c31a06f2dc9113292c02533527feef8cf88b4e2b17e48d658)...done
