    12  # DESCRIPTION
    13  
    14  Use `docker push` to share your images to the [Docker Hub](https://hub.docker.com)
    15  registry or to a self-hosted one.
    16  
    17  Refer to **docker-tag(1)** for more information about valid image and tag names.
    18  
    19  Killing the **docker push** process, for example by pressing **CTRL-c** while it
    20  is running in a terminal, terminates the push operation.
    21  
    22  Registry credentials are managed by **docker-login(1)**.
    23  
    24  
    25  # OPTIONS

    33  # EXAMPLES
    34  
    35  ## Pushing a new image to a registry
    36  
    37  First save the new image by finding the container ID (using **docker ps**)
    38  and then committing it to a new image name.  Note that only a-z0-9-_. are
    39  allowed when naming images:
    40  
    41      # docker commit c16378f943fe rhel-httpd
    42  
    43  Now, push the image to the registry using the image ID. In this example the
    44  registry is on host named `registry-host` and listening on port `5000`. To do
    45  this, tag the image with the host name or IP address, and the port of the
    46  registry:
    47  
    48      # docker tag rhel-httpd registry-host:5000/myadmin/rhel-httpd
    49      # docker push registry-host:5000/myadmin/rhel-httpd
    50  
    51  Check that this worked by running:
    52  
    53      # docker images
    54  
    55  You should see both `rhel-httpd` and `registry-host:5000/myadmin/rhel-httpd`
    56  listed.
