NAME

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

SYNOPSIS

docker push [ --help] NAME[:TAG] | [REGISTRY_HOST[:REGISTRY_PORT]/]NAME[:TAG]
 
 

DESCRIPTION

This command pushes an image or a repository to a registry. If you do not specify a REGISTRY_HOST, the command uses Docker's public registry located at registry-1.docker.io by default.
 
 

OPTIONS

--help
Print usage statement
 
 

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. 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.
 
Registry credentials are managed by docker-login(1).
