AWS CDK: Lambda Fleet

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

Intention

Have a CloudFormation stack with multiple AWS Lambda functions in different langauges.

Usage

Create a folder like src/lambda-node-example and store a Dockerfile there:

FROM amazon/aws-lambda-nodejs:12

ARG FUNCTION_DIR="/var/task"

RUN mkdir -p ${FUNCTION_DIR}

COPY package.json ${FUNCTION_DIR}

RUN npm install

COPY handler.js ${FUNCTION_DIR}

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. Run yarn deploy to deploy all functions and output the function's arn.

Examples

• src/lambda-node-example
• src/lambda-python-example
• src/lambda-typescript-example

Deployment

# Deploy all functions

$ > yarn deploy

Usage

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"
