NAME

docker-push - Push an image or a repository to the registry

SYNOPSIS

docker push NAME[:TAG]

DESCRIPTION

Push an image or a repository to a registry. The default registry is the Docker Hub located at hub.docker.com. However the image can be pushed to another, perhaps private, registry as demonstrated in the example below.

OPTIONS

There are no available options.

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:

# 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. Default Docker commands will push to the default hub.docker.com registry. Instead, push to the local registry, which is on a host called registry-host*. 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.
