docker-image-push - Push an image or a repository to a registry
docker image push [OPTIONS] NAME[:TAG]

Pushing a new image to a registry
First save the new image by finding the container ID (using docker
container ls) and then committing it to a new image name. Note that
only a-z0-9-_. are allowed when naming images:
# docker container commit c16378f943fe rhel-httpd
Now, push the image to the registry using the image ID. In this example
the registry is on host named registry-host and listening on port 5000.
To do this, tag the image with the host name or IP address, and the
port of the registry:
# docker image tag rhel-httpd registry-host:5000/myadmin/rhel-httpd
# docker image push registry-host:5000/myadmin/rhel-httpd
Check that this worked by running:
# docker image ls
You should see both rhel-httpd and
