## Description
|
|
|
|
Use `docker image push` to share your images to the [Docker Hub](https://hub.docker.com)
|
|
registry or to a self-hosted one.
|
|
|
|
Refer to the [`docker image tag`](tag.md) reference for more information about valid
|
|
image and tag names.
|
|
|
|
Killing the `docker image 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 container ls`](ps.md))
|
|
and then committing it to a new image name. Note that only `a-z0-9-_.` are
|
|
allowed when naming images:
|
|
|
|
```console
|
|
$ docker container commit c16378f943fe rhel-httpd:latest
|
|
```
|
|
|
|
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:
|
|
|
|
```console
|
|
$ docker image tag rhel-httpd:latest registry-host:5000/myadmin/rhel-httpd:latest
|
|
|
|
$ docker image push registry-host:5000/myadmin/rhel-httpd:latest
|
|
```
|
|
|
|
Check that this worked by running:
|
|
|
|
```console
|
|
$ docker image ls
|
|
```
|
|
|
|
You should see both `rhel-httpd` and `registry-host:5000/myadmin/rhel-httpd`
|
|
listed.
|
|
|
|
### <a name="all-tags"></a> Push all tags of an image (-a, --all-tags)
|
|
|
|
Use the `-a` (or `--all-tags`) option to push all tags of a local image.
|
|
|
|
The following example creates multiple tags for an image, and pushes all those
|
|
tags to Docker Hub.
|
|
|
|
|
|
```console
|
|
$ docker image tag myimage registry-host:5000/myname/myimage:latest
|
|
$ docker image tag myimage registry-host:5000/myname/myimage:v1.0.1
|
|
$ docker image tag myimage registry-host:5000/myname/myimage:v1.0
|
|
$ docker image tag myimage registry-host:5000/myname/myimage:v1
|
|
```
|
|
|
|
The image is now tagged under multiple names:
|
|
|
|
```console
|
|
$ docker image ls
|
|
|
|
REPOSITORY TAG IMAGE ID CREATED SIZE
|
|
myimage latest 6d5fcfe5ff17 2 hours ago 1.22MB
|
|
registry-host:5000/myname/myimage latest 6d5fcfe5ff17 2 hours ago 1.22MB
|
|
registry-host:5000/myname/myimage v1 6d5fcfe5ff17 2 hours ago 1.22MB
|
|
registry-host:5000/myname/myimage v1.0 6d5fcfe5ff17 2 hours ago 1.22MB
|
|
registry-host:5000/myname/myimage v1.0.1 6d5fcfe5ff17 2 hours ago 1.22MB
|
|
```
|
|
|
|
When pushing with the `--all-tags` option, all tags of the `registry-host:5000/myname/myimage`
|
|
image are pushed:
|
|
|
|
|
|
```console
|
|
$ docker image push --all-tags registry-host:5000/myname/myimage
|
|
|
|
The push refers to repository [registry-host:5000/myname/myimage]
