## Examples
|
|
|
|
### Pushing a new image to a registry
|
|
|
|
First save the new image by finding the container ID (using **docker container ls**)
|
|
and then committing it to a new image name. Note that only `a-z0-9-_.` are
|
|
allowed when naming images:
|
|
|
|
$ docker container 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 image tag rhel-httpd registry-host:5000/myadmin/rhel-httpd
|
|
$ docker image push registry-host:5000/myadmin/rhel-httpd
|
|
|
|
Check that this worked by running:
|
|
|
|
$ docker image ls
|
|
|
|
You should see both `rhel-httpd` and `registry-host:5000/myadmin/rhel-httpd`
|
|
listed.
