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.handle" \
        --runtime provided \
        --role arn:aws:iam::xxxxxxxxxxxx:role/service-role/lambda-custom-runtime-perl-role \
        --layers "arn:aws:lambda:$REGION:445285296882:layer:perl-5-30-runtime:3"

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!

The Layer ARN list is here.

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.

  5. Click Create button.

  6. Use the layer created. For detail, see Use Prebuild Public Lambda Layer section.

Run in Local using Docker

https://hub.docker.com/r/shogo82148/p5-aws-lambda is pre-build docker image based on https://hub.docker.com/r/lambci/lambda/

    # Install the dependency.
    docker run --rm -v $(PWD):/var/task shogo82148/p5-aws-lambda:build-5.30 \
        cpanm --notest --local-lib extlocal --no-man-pages --installdeps .

    # run an event.
    docker run --rm -v $(PWD):/var/task shogo82148/p5-aws-lambda:5.30 \
        handler.handle '{"some":"event"}'

AWS XRay SUPPORT

AWS X-Ray is a service that collects data about requests that your application serves. You can trace AWS Lambda requests and sends segment data with pre-install module AWS::XRay.

    use utf8;
    use warnings;
    use strict;
    use AWS::XRay qw/ capture /;

    sub handle {
        my ($payload, $context) = @_;
        capture "myApp" => sub {
            capture "nested" => sub {
                # do something ...
            };
        };
        capture "another" => sub {
            # do something ...
        };
        return;
    }

    1;

Paws SUPPORT

If you want to call AWS API from your Lambda function, you can use a pre-build Lambda Layer for Paws - A Perl SDK for AWS (Amazon Web Services) APIs.

Use Prebuild Public Lambda Layer

Add the perl-runtime layer and the perl-paws layer into your lambda function.

    aws --region "$REGION" --profile "$PROFILE" lambda create-function \
        --function-name "hello-perl" \
        --zip-file "fileb://handler.zip" \
        --handler "handler.handle" \
        --runtime provided \
        --role arn:aws:iam::xxxxxxxxxxxx:role/service-role/lambda-custom-runtime-perl-role \
        --layers \
            "arn:aws:lambda:$REGION:445285296882:layer:perl-5-30-runtime:3" \
            "arn:aws:lambda:$REGION:445285296882:layer:perl-5-30-paws:2"

Now, you can use Paws to call AWS API from your Lambda function.

    use Paws;
    my $obj = Paws->service('...');
    my $res = $obj->MethodCall(Arg1 => $val1, Arg2 => $val2);
    print $res->AttributeFromResult;

    docker run --rm \
        -v $(PWD):/var/task \
        -v $(PATH_TO_LAYER_DIR)/lib/perl5/site_perl:/opt/lib/perl5/site_perl \
