README

AWS CDK: Lambda Fleet

MIT License cdk-lambda-fleet on NPM

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

Examples

CDK Construct

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

$ > yarn install cdk-lambda-fleet

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:

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

# Deploy all functions

$ > yarn deploy
