## Description
|
||
|
|
|
||
|
|
Use `docker push` to share your images to the [Docker Hub](https://hub.docker.com)
|
||
|
|
registry or to a self-hosted one.
|
||
|
|
|
||
|
|
Refer to the [`docker tag`](tag.md) reference for more information about valid
|
||
|
|
image and tag names.
|
||
|
|
|
||
|
|
Killing the `docker push` process, for example by pressing `CTRL-c` while it is
|
||
|
|
running in a terminal, terminates the push operation.
|
||
|
|
|
||
|
|
Progress bars are shown during docker push, which show the uncompressed size. The
|
||
|
|
actual amount of data that's pushed will be compressed before sending, so the uploaded
|
||
|
|
size will not be reflected by the progress bar.
|
||
|
|
|
||
|
|
Registry credentials are managed by [docker login](login.md).
|
||
|
|
|
||
|
|
### Concurrent uploads
|
||
|
|
|
||
|
|
By default the Docker daemon will push five layers of an image at a time.
|
||
|
|
If you are on a low bandwidth connection this may cause timeout issues and you may want to lower
|
||
|
|
this via the `--max-concurrent-uploads` daemon option. See the
|
||
|
|
[daemon documentation](dockerd.md) for more details.
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
### Push a new image to a registry
|
||
|
|
|
||
|
|
First save the new image by finding the container ID (using [`docker ps`](ps.md))
|
||
|
|
and then committing it to a new image name. Note that only `a-z0-9-_.` are
|
||
|
|
allowed when naming images:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ 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:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ docker tag rhel-httpd registry-host:5000/myadmin/rhel-httpd
|
||
|
|
|
||
|
|
$ docker push registry-host:5000/myadmin/rhel-httpd
|
||
|
|
```
|
||
|
|
|
||
|
|
Check that this worked by running:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ docker images
|
||
|
|
```
|
||
|
|
|
||
|
|
You should see both `rhel-httpd` and `registry-host:5000/myadmin/rhel-httpd`
|
||
|
|
listed.
