docker push [OPTIONS] NAME[:TAG]

docker The base command for the Docker CLI.

Extended description

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.

Concurrent uploads

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.

Examples

Push 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.
