# 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. Refer to **docker-tag(1)** for more
information about valid image and tag names.
# 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)**.
