# AWS CDK: Lambda Fleet

> Deploy multiple AWS Lambda functions as container images to Amazon ECR with CDK.

## Examples

- [`src/lambda-node-example`](src/lambda-node-example)

- [`src/lambda-python-example`](src/lambda-python-example)

- [`src/lambda-typescript-example`](src/lambda-typescript-example)

## CDK Construct

When using the AWS CDK in TypeScript, you can use the published `LambdaFleet` construct:

```bash

$ > yarn install cdk-lambda-fleet

```

```typescript

import * as path from "path";

import * as cdk from "@aws-cdk/core";

import { LambdaFleet } from "cdk-lambda-fleet";

export class FleetStack extends cdk.Stack {

  constructor(scope: cdk.App, id: string, props?: cdk.StackProps) {

    super(scope, id, props);

    new LambdaFleet(this, "Fleet", {

      path: path.resolve(__dirname, "../src"),

    });

  }

}

```

### Configuration

You can fork this repository and create a folder like `src/lambda-python-example` and store a `Dockerfile` there:

```Dockerfile

FROM amazon/aws-lambda-python:3.8

COPY requirements.txt ./

RUN pip install -r requirements.txt

COPY handler.py ./

CMD [ "handler.run" ]

```

Using the **AWS CDK**, a docker image will be created and deployed to **Amazon ECR** for every folder in `src/`. After uploading the image, an **AWS Lambda** will be created or updated to use the latest image.

## Deployment

```bash

# Deploy all functions

$ > yarn deploy

[…]

Fleet.FleetLambdaNodeExampleArnXYZ = "arn:aws:lambda:eu-central-1:123:function:Fleet-FleetLambdaNodeExampleXYZ-XYZ"

Fleet.FleetLambdaPythonExampleArnXYZ = "arn:aws:lambda:eu-central-1:123:function:Fleet-FleetLambdaPythonExampleXYZ-XYZ"

Fleet.FleetLambdaTypescriptExampleArnXYZ = "arn:aws:lambda:eu-central-1:123:function:Fleet-FleetLambdaTypescriptExampleXYZ-XYZ"

```
