Caws

Chaos on AWS Library and Lambda

Usage

Rust

• Create a new Rust project with cargo new --bin PROJECT_NAME

• Add the necessary dependencies to you Cargo.toml: [dependencies] tokio = { version = "1.23.0", features = ["full"] } serde_json = "1.0.91" lambda_runtime = "0.7.2" caws = "1.0.0"

• Change main.rs to the following code:

``` use caws::{DestructionResults, Key, Kraken}; use lambdaruntime::{servicefn, Error, LambdaEvent}; use serdejson::{fromvalue, to_value, Value};

[tokio::main]

async fn main() -> Result<(), Error> { lambdaruntime::run(servicefn(func)).await?; Ok(()) }

async fn func(event: LambdaEvent) -> Result { let event = event.payload; let key: Key = from_value(event)?;

let kraken = Kraken::new();
let destruction_results = kraken.release(key).await?;

Ok(to_value(DestructionResults {
    execution_status: destruction_results.execution_status,
})?)

}

`` * Build and package your code with:cargo lambda build --release --x86-64 --output-format zip` (you might need to install cargo-lambda first)

CDK

• Add the dependency to your cdk project

"caws-constructs": "^0.1.4",

• Import the CawsLambda construct:

import { CawsLambda } from 'caws-constructs';

• Create the Lambda:

new CawsLambda(this, 'lambda-id', { functionName: 'function-name', brazilPackagePath: 'path/to/bootstrap.zip', env: [ "agents": { //Configure here the agents that you want to enable "test": ["dummy"] } ] })

• Run cdk deploy to create the lambda and eventbridge schedule
