Command​

Use the following command to transform Terraform template to ROS template and generate template file in the current directory:

You can also use --source-format/-S terraform to explicitly specify the category of the original template:

rostran transform templates/terraform/alicloud -S terraform

Original Terraform Template​

  • main.tf
# Configure the AliCloud Provider
provider "alicloud" {}

# Create VPC and VSwitch
resource "alicloud_vpc" "myvpc" {
  cidr_block = "172.16.0.0/12"
  name       = "myvpc"
}

resource "alicloud_vswitch" "myvswitch" {
  vpc_id            = alicloud_vpc.myvpc.id
  cidr_block        = "172.16.0.0/21"
  availability_zone = "cn-beijing-g"
  name              = "myvswitch"
}
  • output.tf
output "vpc_id" {
  value = alicloud_vpc.myvpc.id
}

output "vswitch_id" {
  value = alicloud_vswitch.myvswitch.id
}
