If you have created your own Docker image locally and want to move it to another docker host without first uploading it to a docker or private local repository you can use docker’s save
command to save your image locally as ordinary tar archive archive and the copy and re-deploy it on another docker system. For example here we first make a backup of our docker image eg. linuxconfig
:
# docker save linuxconfig > linuxconfig.tar
The above command have created a tarball of our local docker image linuxconfig
which we now can move to another system and re-deploy it with Docker’s command load
:
# docker load -i linuxconfig.tar
All done you should now see your docker image among the rest of your images using docker’s images
command:
# docker images
