        Deploy Bash Lambda Functions with AWS CDK
        
        # Why
        
        AWS Lambda has the [docker container image support](https://aws.amazon.com/tw/blogs/aws/new-for-aws-lambda-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](https://github.com/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
        
        ```python
        # 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()
        ```
        
        ## Custom Dockerfile
        
        In some cases, you may customize your own `Dockerfile`, for instances:
        
        1. You need extra tools or utilities such as `kubectl` or `helm`
        2. You need build from your own base image
        
        In these cases, create a custom `Dockerfile` as below and add extra utilities i.e. `kubectl`:

        ```bash
        FROM public.ecr.aws/lambda/provided:al2
        
        RUN yum install -y unzip jq
        
        # install aws-cli v2
        RUN curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip" && \
          unzip awscliv2.zip && \
          ./aws/install
        
        # install kubectl
        RUN curl -o kubectl https://amazon-eks.s3.us-west-2.amazonaws.com/1.19.6/2021-01-05/bin/linux/amd64/kubectl && \
          chmod +x kubectl && \
          mv kubectl /usr/local/bin/kubectl
        
        COPY bootstrap /var/runtime/bootstrap
        COPY function.sh /var/task/function.sh
        COPY main.sh /var/task/main.sh
        RUN chmod +x /var/runtime/bootstrap /var/task/function.sh /var/task/main.sh
        
        WORKDIR /var/task
        CMD [ "function.sh.handler" ]
        ```
        
        </details>
        
        Specify your own `Dockerfile` with the `dockerfile` property.
        
        ```python
        # Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
        BashExecFunction(stack, "Demo",
            script=path.join(__dirname, "../demo.sh"),
            dockerfile=path.join(__dirname, "../Dockerfile")
        )
        ```
