Deploy Bash Lambda Functions with AWS CDK

Why

AWS Lambda has the docker container image support since AWS re:Invent 2020 which allows you to run your Lambda code in a custom container image. Inspired by nikovirtala/cdk-eks-experiment, cdk-lambda-bash allows you to specify a local shell script and bundle it up as a custom resource in your cdk stack. On cdk deployment, your shell script will be executed in a Lambda container environment.

BashExecFunction

At this moment, we are offering BashExecFunction construct class which is a high-level abstraction of lambda.Function. By defining the script property which poins to your local shell script, on cdk deploy, this script will be bundled into a custom docker image and published as a lambda.DockerImageFunction.

If you fn.run(), a custom resource will be created and the lambda.DockerImageFunction will be executed on deployment.

Sample

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
app = cdk.App()

stack = cdk.Stack(app, "my-stack")

# bundle your Lambda function to execute the local demo.sh in container
fn = BashExecFunction(stack, "Demo",
    script=path.join(__dirname, "../demo.sh")
)

# run it as custom resource on deployment
fn.run()
