Usage: docker push [OPTIONS] NAME[:TAG] Push an image or a repository to a registry Options: --disable-content-trust Skip image verification (default true) --help Print usage
Use 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 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.
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 this via the --max-concurrent-uploads daemon option. See the daemon documentation for more details.
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.
