## 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 lambda_runtime::{service_fn, Error, LambdaEvent};
use serde_json::{from_value, to_value, Value};
#[tokio::main]
async fn main() -> Result<(), Error> {
lambda_runtime::run(service_fn(func)).await?;
Ok(())
}
async fn func(event: LambdaEvent<Value>) -> Result<Value, Error> {
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](https://github.com/cargo-lambda/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
