A simple way to spawn ubuntu VMs

TL;DR just do it

$ terraform init

# see minimal variables below

$ terraform plan
$ terraform apply

variables

minimal variables needed to run

$ cat < EOF > terraform.tfvars
hostname = "server1"
domainname = "example.com"
EOF

terraform workspaces

terraform workspace new server1.example.com
terraform workspace select server1.example.com
terraform apply -var="hostname=server1" -var="domainname=example.com"
