}

Digital Ocean Example

 provisioner "remote-exec" {
   inline = ["sudo apt update", "sudo apt install python3 -y", "echo Done!"]

   connection {
     host        = self.ipv4_address
     type        = "ssh"
     user        = "root"
     private_key = file(var.pvt_key)
   }
 }

 provisioner "local-exec" {
   command = "ANSIBLE_HOST_KEY_CHECKING=False ansible-playbook -u root -i '${self.ipv4_address},' --private-key ${var.pvt_key} -e 'pub_key=${var.pub_key}' apache-install.yml"
