    16  # push
    17  
    18  ```markdown
    19  Usage:  docker push [OPTIONS] NAME[:TAG]
    20  
    21  Push an image or a repository to a registry
    22  
    23  Options:
    24        --disable-content-trust   Skip image verification (default true)
    25        --help                    Print usage
    26  ```
    27  
    28  Use `docker push` to share your images to the [Docker Hub](https://hub.docker.com)
    29  registry or to a self-hosted one.
    30  
    31  Refer to the [`docker tag`](tag.md) reference for more information about valid
    32  image and tag names.
    33  
    34  Killing the `docker push` process, for example by pressing `CTRL-c` while it is
    35  running in a terminal, terminates the push operation.
    36  
    37  Registry credentials are managed by [docker login](login.md).
    38  
    39  ## Concurrent uploads
    40  
    41  By default the Docker daemon will push five layers of an image at a time.
    42  If you are on a low bandwidth connection this may cause timeout issues and you may want to lower
    43  this via the `--max-concurrent-uploads` daemon option. See the
    44  [daemon documentation](dockerd.md) for more details.
    45  
    46  ## Examples
    47  
    48  ### Pushing a new image to a registry
    49  
    50  First save the new image by finding the container ID (using [`docker ps`](ps.md))
    51  and then committing it to a new image name.  Note that only `a-z0-9-_.` are
    52  allowed when naming images:
    53  
    54  ```bash
    55  $ docker commit c16378f943fe rhel-httpd
    56  ```
    57  
    58  Now, push the image to the registry using the image ID. In this example the
    59  registry is on host named `registry-host` and listening on port `5000`. To do
    60  this, tag the image with the host name or IP address, and the port of the
    61  registry:
    62  
    63  ```bash
    64  $ docker tag rhel-httpd registry-host:5000/myadmin/rhel-httpd
    65  $ docker push registry-host:5000/myadmin/rhel-httpd
    66  ```
    67  
    68  Check that this worked by running:
    69  
    70  ```bash
    71  $ docker images
    72  ```
    73  
    74  You should see both `rhel-httpd` and `registry-host:5000/myadmin/rhel-httpd`
    75  listed.
