IV. Import and export images

In addition to pushing the image to the repository, you can also export the image, copy it to another host and then export it.

Export format: docker save [option] image [image]

-o: packaged as

[root@node1 ~] # docker save-o test.tar b1:v1.1 b1:v2 [root@node1 ~] # lsanaconda-ks.cfg initial-setup-ks.cfg test.tar Public template Video Picture document download Music Desktop [root@node1 ~] #

Import format: docker load

-i:input

At this point, I believe you have a deeper understanding of "the basis of docker image management and the method of making images". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
