# NAME

AWS::Lambda - It's Perl support for AWS Lambda Custom Runtime.

# SYNOPSIS

Save the following Perl script as `handler.pl`.

    sub handle {
        my ($payload, $context) = @_;
        return $payload;
    }

and then, zip the script.

    zip handler.zip handler.pl

Finally, create new function using awscli.

    aws --region "$REGION" --profile "$PROFILE" lambda create-function \
        --function-name "hello-perl" \
        --zip-file "fileb://handler.zip" \
        --handler "handler.function" \
        --runtime provided \
        --role arn:aws:iam::xxxxxxxxxxxx:role/service-role/lambda-custom-runtime-perl-role \
        --layers "arn:aws:lambda:$REGION:445285296882:layer:perl-5-28-runtime:5"

# DESCRIPTION

This package makes it easy to run AWS Lambda Functions written in Perl.

## Use Prebuild Public Lambda Layer

1. Login to your AWS Account and go to the Lambda Console.
2. Create a new function and give it a name and an IAM Role.
3. For the "Runtime" selection, select **Use custom runtime in function code or layer**.
4. In the "Designer" section of your function dashboard, select the **Layers** box.
5. Scroll down to the "Referenced Layers" section and click **Add a layer**.
6. Select the **Provide a layer version ARN** option, then copy/paste the Layer ARN for your region.
7. Click the **Add** button.
8. Click **Save** in the upper right.
9. Upload your code and start using Perl in AWS Lambda!

## Use Prebuild Zip Archive

1. Login to your AWS Account and go to the Lambda Console.
2. Create a new layer and give it a name.
3. For the "Code entry type" selection, select **Upload a file from Amazon S3**.
4. In the "License" section, input [https://github.com/shogo82148/p5-aws-lambda/blob/master/LICENSE](https://github.com/shogo82148/p5-aws-lambda/blob/master/LICENSE).
5. Click **Create** button.
6. Use the layer created. For detail, see Use Prebuild Public Lambda Layer section.
