Klotho - write AWS applications at lightning speed

Terraform/CDK alternative designed for developers

What is Klotho?

Klotho is a developer-centric cloud infra-as-code deployment tool with high level constructs. It lets you think in terms of containers, functions, APIs and databases and combining them freely.

Example Klotho infra.py

infra.py

import os
from pathlib import Path

import klotho
import klotho.aws as aws

# Create the Application instance
app = klotho.Application(
    "my-sample-app",
    project="my-project",
    environment="default",
    default_region="us-west-2",  
)

dir = Path(__file__).parent.absolute()

# Create a dynamodb instance with 2 indexed attributes
dynamodb = aws.DynamoDB(
    "my-dynamodb",
    attributes=[
        {"Name": "id", "Type": "S"},    
        {"Name": "data", "Type": "S"},  
    ],
    hash_key="id",
    range_key="data"
)

# Create a lambda function that reads in code and deploys it as a zip file
my_function = aws.Function(
    "my-function",
    handler="handler.handler",
    runtime="python3.12",
    code=str(dir),
)

# Bind the dynamodb instance to the lambda function
my_function.bind(dynamodb)

# Create an ECS container
my_container = aws.Container(
    "my-container",
    dockerfile=str(dir / "container" / "Dockerfile"),
    context=str(dir),
)

# Create a Postgres instance with plain text password
my_postgres = aws.Postgres(
    "my-postgres",
    username="admin",
    password="password123!",
    database="mydb",
)

# Bind the postgres instance to the container
my_container.bind(my_postgres)

# Create an API Gateway instance
api = aws.Api("my-api")

# Bind the lambda function to the API Gateway on the /function route
api.route(
  routes: [
    RouteArgs(path="/function", method="ANY")
  ], my_function
)

# Bind the container to the API Gateway on the /container route
api.route(
  routes: [
    RouteArgs(path="/container", method="ANY")
  ], my_container
)
