1. Export container

If you want to export a local container, you can use the docker export command to export the container snapshot to a local file.

2. Import container snapshots

You can use docker import to import as a mirror from a container snapshot file, for example

$cat ubuntu.tar | sudo docker import-test/ubuntu:v1.0$ sudo docker imagesREPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZEtest/ubuntu v1.0 9d37a6082e97 About a minute ago 171.3 MB

Alternatively, you can import it by specifying URL or a directory, such as

The copy code is as follows:

$sudo docker import http://example.com/exampleimage.tgz example/imagerepo

* Note: users can use docker load to import image storage files to the local image library, or docker import to import a container snapshot to the local image library. The difference between the two is that the container snapshot file will discard all history and metadata information (that is, only save the snapshot state of the container at that time), while the mirror storage file will keep the full record and be large. In addition, metadata information such as labels can be reassigned when importing from a container snapshot file.
