Create the Day0 Configuration With a Fixed Configuration for GCP

The fixed configuration will auto-generate the cluster bootstrap configuration.

{
    "AdminPassword": "password",
    "Hostname": "hostname",
    "FirewallMode": "Routed",
    "ManageLocally": "No",
                "Diagnostic": "OFF",       //Optional user input from version 7.4.1 - use to deploy cluster without Diagnostic interface
    "Cluster": {
        "CclSubnetRange": "ip_address_start ip_address_end",
        "ClusterGroupName": "cluster_name"
    }
}

For example:

{
    "AdminPassword": "DeanW1nche$ter",
    "Hostname": "ciscoftdv",
    "FirewallMode": "Routed",
    "ManageLocally": "No",
    "Cluster": {
        "CclSubnetRange": "10.10.55.2 10.10.55.253",     //mandatory user input
        "ClusterGroupName": "ftdv-cluster"               //mandatory user input
    }
}

For the CclSubnetRange variable, note that you cannot use the first two IP addresses and the last two IP addresses in the subnet. See Reserved IP addresses in IPv4 subnets for more information. Ensure that you have at least 16 available IP addresses for clustering. Some examples of start and end IP addresses are given below.
