docker-push — Push an image or a repository to a registry
docker push [--help] NAME[:TAG] | [REGISTRY_HOST[:REGISTRY_PORT]/]NAME[:TAG]
docker push to share your images to the Docker Hub ⟨https://hub.docker.com⟩ registry or to a self-hosted one.
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).
Skip image verification (default true)
Print usage statement
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
