# 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](https://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.
