The `shared_secret` value used in `vpn_ha` module resource `"google_compute_vpn_tunnel" "tunnels"` definition is not exposed in `variables.tf` file

[damianjaniszewski]

The only way to use it is actually define its value for each tunnel in the code. Since this is sensitive value, it would be good to use from command line, ex:

terraform apply -var shared_secret='["tunnel-0-very-secret-shared-key", "tunnel-1-another-secret-shared-key"]'

Example definition in variables.tf:

variable "shared_secret" {
  type        = list(string)
  description = "Please enter the shared secret/pre-shared key"
  default     = []
}

You can pass the shared_secret as part of the tunnels variable.
