You can export any Docker image stored on any node. This is useful when you need to move a container from one host to another, or simply make a backup of the images.
If you export a container to a tar file, the volumes won't get exported with it. You will need to save the data from those volumes using a different method.
From the menu select Images, select the image you want to export then click Export this image.
When the warning message appears, click Continue.
When the image has downloaded, a success message will appear, and your browser should automatically download the resulting tar file.
