    If run with no arguments you will be prompted for cloud provider and region

    --cloud_provider <arg>      A space separated list of providers to enable.
                                Providers are "aws", "azure", and "google".
                                The default is "none".

    --aws_region <arg>          Default region for aws.

    --google_region <arg>       Default region for google.
    --google_zone <arg>         Default zone for google.

    --azure_region <arg>        Default region for Azure.

    --quiet                     Sets cloud provider to "none". You will need to
                                edit /etc/default/spinnaker manually
                                cannot be used with --cloud_provider.

    --repository <url>          Obtain Spinnaker packages from the <url>
                                rather than the default repository, which is
                                $REPOSITORY_URL

    --dependencies_only         Do not install any Spinnaker services.
                                Only install the dependencies. This is intended
                                for development scenarios only.

    --google_cloud_logging      Install Google Cloud Logging support. This
                                is independent of installing on Google Cloud
                                Platform, but you may require additional
                                authorization. See https://cloud.google.com/logging/docs/agent/authorization#install_private-key_authorization

    --google_cloud_monitoring   Install Google Cloud Monitoring support. This
                                is independent of installing on Google Cloud
                                Platform, but you may require additional
                                authorization. See https://cloud.google.com/monitoring/api/authentication

    --local-install             For Spinnaker and Java packages, download
                                packages and install using dpkg instead of
                                apt. Use this option only if you are having
                                issues with the bintray repositories.
                                If you use this option you must manually
                                install openjdk-8-jdk.

    --home_dir                  Override where user home directories reside
                                example: /export/home vs /home

    --install_cassandra         Force install of cassandra.

    --noinstall_cassandra       Do not install cassandra.
