PY2Terraform

Prototype/concept for building terraform configs using python.
May be useful for deploying flask/django apps by building the cloud configs also in python.

Usage

Extending

from py2terraform.types import TerraformBlockBase

class AWSProvider(TerraformBlockBase):
    # Define constant values
    _block_category = "provider"
    _block_type     = "aws"

    # Define defaults
    def __post_init__(self):
        self.set_params(region = "us-east-1")
        self.add_child_blocks(
            ...
        )

Examples

Desired Output

provider "aws" {
    region = "us-east-1"
}

resource "aws_instance" "my_instance" {
    ami           = "my-ami"
    instance_type = "t2.micro"

    network_interface {
        network_interface_id = "my-interface-id"
        device_index         = 0
    }
}

Python Code

import py2terraform

doc = py2terraform.TerraformDocument()

provider = py2terraform.blocks.TerraformProviderBlock(
    block_type  = "aws",
    params      = {
        "region"    : "us-east-1"
    }
)

instance = py2terraform.blocks.TerraformResourceBlock(
    block_type = "aws_instance",
    block_name = "my_instance",
    params     = {
        "ami"           : "my-ami",
        "instance_type" : "t2.micro"
    }
)
instance_network_interface = py2terraform.types.TerraformBlockBase(
    block_category  = "network_interface",
    params          = {
        "network_interface_id"  : "my-interface-id",
        "device_index"          : 0
    }
)

instance.add_child_blocks(instance_network_interface)

doc.add_blocks(
    provider,
    instance
)

print(doc)

Console Output

provider "aws" {
        region  = "us-east-1"
}

resource "aws_instance" "my_instance" {
        ami     = "my-ami"
        instance_type   = "t2.micro"

        network_interface {
                network_interface_id    = "my-interface-id"
                device_index    = 0
        }
}
