The below command will create 4 nodes in DigitalOcean. They will be named `testnet-servers-node0` to `testnet-servers-node3` and they will be tagged as `testnet-servers`.
```
DO_API_TOKEN="<The API token received from DigitalOcean>"
SSH_ID="<The SSH ID received from the curl call above.>"
terraform apply -var TESTNET_NAME="testnet-servers" -var servers=4 -var DO_API_TOKEN="$DO_API_TOKEN" -var ssh_keys=[$SSH_ID]
SSH_IDS="[ \"<The SSH ID received from the curl call above.>\" ]"
terraform apply -var TESTNET_NAME="testnet-servers" -var servers=4 -var DO_API_TOKEN="$DO_API_TOKEN" -var ssh_keys=$SSH_IDS
```
Note: `ssh_keys` is a list of strings. You can add multiple keys. For example: `["1234567","9876543"]`.
Alternatively you can use the default settings. The number of default servers is 4 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.
