Description:

def image_alias_add(image,
                    alias,
                    description='',
                    remote_addr=None,
                    cert=None,
                    key=None,
                    verify_cert=True):
    ''' Create an alias on the given image

        image :
            An image alias, a fingerprint or a image object

        alias :
            The alias to add

        description :
            Description of the alias

        remote_addr :
            An URL to a remote Server, you also have to give cert and key if
            you provide remote_addr and its a TCP Address!

            Examples:
                https://myserver.lan:8443
                /var/lib/mysocket.sock

        cert :
            PEM Formatted SSL Certificate.

            Examples:
                ~/.config/lxc/client.crt

        key :
            PEM Formatted SSL Key.

            Examples:
                ~/.config/lxc/client.key

        verify_cert : True
            Wherever to verify the cert, this is by default True
            but in the most cases you want to set it off as LXD
            normaly uses self-signed certificates.

        CLI Examples:

        .. code-block:: bash

            $ salt '*' lxd.image_alias_add xenial/amd64 x "Short version of xenial/amd64"
    '''
    image = _verify_image(image, remote_addr, cert, key, verify_cert)

    for alias_info in image.aliases:
        if alias_info['name'] == alias:
            return True
    image.add_alias(alias, description)

    return True
