The eight input variables are docuemented below:
1. infrastructure
2. kubernetes_services
3. ow_cluster_ready
4. ow_kubectl_ready
5. openwisp_services
6. persistent_data
7. kubernetes_configmap
8. openwisp_deployments
Details about the infrastructure.
name : Name of the provider.
Valid options are: ["google",]
http_loadbalancer_name : Name of the http_loadbalancer. (Useful for annotations in kubernetes Ingress)
openvpn_loadbalancer_address : IP Address to be assigned for openvpn kubernetes loadbalancer.
freeradius_loadbalancer_address : IP Address to be assigned for freeradius kubernetes loadbalancer.
cluster:
name : Name of the kubernetes cluster.
nodes_cidr_range : Address range for pods.
pods_cidr_range : Address range for pods.
services_cidr_range : Address range for ClusterIP services.
endpoint : Kubernetes cluster endpoint IP address. (example: 192.168.2.25)
ca_certificate : ca_certificate of the cluster that needs to be decoded in base64 for authentication.
access_token : Access token required for authentication to perform actions in the cluster.
database:
enabled : Flag for cloud provided database being used. (Like Google Cloud SQL)
sslmode : [PSQL database sslmodes](https://www.postgresql.org/docs/9.1/libpq-ssl.html)
ca_cert : Contents of the server certificate file
client_cert : Contents of the client certificate file
client_key : Contents of the client private key
username : Username to login to database
password : Password to login to database
name : Name of the database to be used by openwisp
host : IP address of the database server
Configuration for OpenWISP kubernetes services.
use_cert_manger : (Boolean) Install cert-manager and get TLS certificates for the Ingress.
1. You need `kubectl` pre-configured on your machine.
2. Your domain should be pointing at your Ingress's IP for http01 validation.
3. If used with GCP module, "gcloud_configure" option might be helpful.
cert_manager_link : Link of YAML file to use to install cert-manager.
(Boolean) Resource creation starts when this signal is received, useful for other modules to report when cluster is ready for deployment.
(Boolean) Signal for kubectl configured and ready on local machine.
Flags for enabling/disabling OpenWISP services to be used.
use_openvpn : (Boolean) Setup OpenVPN for management inside cluster.
use_freeradius : (Boolean) Setup freeradius inside cluster.
setup_database : (Boolean) Setup database inside cluster. You would want to
set this as false when you have your own database server or
you are using cloud SQL.
setup_fresh : (Boolean) Flag to initial setup of openwisp. Only required when you
are setting up openwisp & openwisp-database for the first time.
Persistent storage information for the cluster.

postgres_storage_size : Disk size portion to be allocated for postgres database.
sslcert_storage_size : Disk size portion to be allocated for storing postfix sslcert data.
media_storage_size : Disk size portion to be allocated for user uploaded media (like floor plan).
static_storage_size : Disk size portion to be allocated for static data of the website.
html_storage_size : Disk size portion to be allocated for maintaince HTML.
nfs_server:
internal_ip : Valid ClusterIP to be reserved for NFS server.
limit_cpu : CPU limit for the pod
requests_cpu : Minimum CPU requirement for the pod
limit_memory : Memory limit for the pod
requests_memory : Minimum memory requirement for the pod
Options for configmaps are the same as the one available for docker-openwisp image environment options
However, some database options are set in the infrastructure variable.
