I assume you need to save couchdb-cartridge which has an image id of 7ebc8510bc2c:

stratos@Dev-PC:~$ docker images
REPOSITORY                             TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
couchdb-cartridge                      latest              7ebc8510bc2c        17 hours ago        1.102 GB

Save the archiveName image to a tar file. I will use the /media/sf_docker_vm/ to save the image.

stratos@Dev-PC:~$ docker save imageID > /media/sf_docker_vm/archiveName.tar

Copy the archiveName.tar file to your new Docker instance using whatever method works in your environment, for example FTP, SCP, etc.

Run the docker load command on your new Docker instance and specify the location of the image tar file.

stratos@Dev-PC:~$ docker load < /media/sf_docker_vm/archiveName.tar

Finally, run the docker images command to check that the image is now available.

stratos@Dev-PC:~$ docker images
REPOSITORY                             TAG        IMAGE ID         CREATED             VIRTUAL SIZE
couchdb-cartridge                      latest     7ebc8510bc2c     17 hours ago        1.102 GB
192.168.57.30:5042/couchdb-cartridge   latest     bc8510bc2c       17 hours ago        1.102 GB
