Build the hello-perl container image locally:
$ docker build -t hello-perl .
To check if this is working, start the container image locally using the Lambda Runtime Interface Emulator:
$ docker run -p 9000:8080 hello-perl:latest
Now, you can test a function invocation with cURL.
$ curl -XPOST "http://localhost:9000/2015-03-31/functions/function/invocations" -d '{}'
To upload the container image, you need to create a new ECR repository in your account and tag the local image to push it to ECR.
$ aws ecr create-repository --repository-name hello-perl --image-scanning-configuration scanOnPush=true
$ docker tag hello-perl:latest 123412341234.dkr.ecr.sa-east-1.amazonaws.com/hello-perl:latest
$ aws ecr get-login-password | docker login --username AWS --password-stdin 123412341234.dkr.ecr.sa-east-1.amazonaws.com
$ docker push 123412341234.dkr.ecr.sa-east-1.amazonaws.com/hello-perl:latest
Finally, create new function using awscli.
$ aws --region "$REGION" --profile "$PROFILE" lambda create-function \
--function-name "hello-perl" \
--code ImageUri=123412341234.dkr.ecr.sa-east-1.amazonaws.com/hello-perl:latest \
--handler "handler.handle" \
--runtime provided.al2023 \
--role arn:aws:iam::xxxxxxxxxxxx:role/service-role/lambda-custom-runtime-perl-role
## Run in Local using Docker
Prebuilt Docker Images based on [https://hub.docker.com/r/lambci/lambda/](https://hub.docker.com/r/lambci/lambda/) are available.
You can pull from [https://gallery.ecr.aws/shogo82148/p5-aws-lambda](https://gallery.ecr.aws/shogo82148/p5-aws-lambda) or [https://hub.docker.com/r/shogo82148/p5-aws-lambda](https://hub.docker.com/r/shogo82148/p5-aws-lambda),
and build zip archives to deploy.

## AWS X-Ray SUPPORT
[AWS X-Ray](https://aws.amazon.com/xray/) 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](https://metacpan.org/pod/AWS%3A%3AXRay).
use utf8;
use warnings;
use strict;
use AWS::XRay qw/ capture /;
sub handle {
my ($payload, $context) = @_;
capture "myApp" => sub {
capture "nested" => sub {
# do something ...
};
};
capture "another" => sub {
# do something ...
};
return;
}
1;
# Paws SUPPORT
If you want to call AWS API from your Lambda function,
you can use a pre-built Lambda Layer for [Paws](https://metacpan.org/pod/Paws) - A Perl SDK for AWS (Amazon Web Services) APIs.
## Use Prebuilt Public Lambda Layers
Add the perl-runtime layer and the perl-paws layer into your lambda function.
aws --region "$REGION" --profile "$PROFILE" lambda create-function \
--function-name "hello-perl" \
--zip-file "fileb://handler.zip" \
--handler "handler.handle" \
--runtime provided.al2023 \
--role arn:aws:iam::xxxxxxxxxxxx:role/service-role/lambda-custom-runtime-perl-role \
--layers \
"arn:aws:lambda:$REGION:445285296882:layer:perl-5-38-runtime-al2023-x86_64:5" \
"arn:aws:lambda:$REGION:445285296882:layer:perl-5-38-paws-al2023-x86_64:4"
Now, you can use [Paws](https://metacpan.org/pod/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;
The list of all layer ARNs is available on [AWS::Lambda::AL2023](https://metacpan.org/pod/AWS%3A%3ALambda%3A%3AAL2023).
