|docker||The base command for the Docker CLI.|
docker push to share your images to the Docker Hub
registry or to a self-hosted one.
Refer to the
docker tag reference for more information about valid

docker push process, for example by pressing
CTRL-c while it is
running in a terminal, terminates the push operation.
Registry credentials are managed by docker login.
By default the Docker daemon will push five layers of an image at a time.
If you are on a low bandwidth connection this may cause timeout issues and you may want to lower

Push a new image to a registry
First save the new image by finding the container ID (using
and then committing it to a new image name. Note that only
allowed when naming images:
$ docker 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
$ docker tag rhel-httpd registry-host:5000/myadmin/rhel-httpd $ docker push registry-host:5000/myadmin/rhel-httpd
Check that this worked by running:
$ docker images
