Alternatively you can use the default settings. The number of default servers is 7 and the testnet name is `tf-testnet1`. Variables can also be defined as environment variables instead of the command-line. Environment variables that start with `TF_VAR_` will be translated into the Terraform configuration. For example the number of servers can be overriden by setting the `TF_VAR_servers` variable. Alternatively you can use the default settings.
