Refer to **docker-tag(1)** for more information about valid image and tag names. Killing the **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(1)**. # OPTIONS **--disable-content-trust** Skip image verification (default true) **--help** Print usage statement # EXAMPLES ## Pushing a new image to a registry First save the new image by finding the container ID (using **docker ps**) and then committing it to a new image name. Note that only a-z0-9-_. are 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 registry: # 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 You should see both `rhel-httpd` and `registry-host:5000/myadmin/rhel-httpd` listed. # HISTORY April 2014, Originally compiled by William Henry (whenry at redhat dot com) based on docker.com source material and internal work.
