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.
