Using a example is pretty easy.

cd examples/EXAMPLE-NAME
terraform init
terraform plan --var-file="../EXAMPLE-NAME.tfvars"
terraform apply --var-file="../EXAMPLE-NAME.tfvars"

After terraform is run successfully wait a bit until instances are booted. The floating IP associate with your instances is displayed after each terraform run.

To remove everything from your project do:

terraform destroy --var-file="../EXAMPLE-NAME.tfvars"

FAQ

Q: I use the network 192.168.1.0/24 in my project already. Can I change the network?

A: Yes, you can. In .tfvars file you want to use add an overwrite for network_cidr and network_short variable:

network_cidr  = "172.31.1.0/24"
network_short = "172.31.1"
