# 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)**.
