AWS Lambda – Rob Allen's DevNotes

Changing the AWS API Gateway response status code in SAM

When creating an API with AWS Lambda and Api Gateway, I discovered that a client request to a given resource with a verb that wasn't supported resulted in an unexpected response. You can see this from this curl command to the /test resource which is only defined for GET:

$ curl -i -X PUT https://mh5rwr9q25.execute-api.eu-west-2.amazonaws.com/prod/test
HTTP/2 403
content-type: application/json
content-length: 42

{"message":"Missing Authentication Token"}

HTTP/2 403

content-type: application/json

content-length: 42

{"message":"Missing Authentication Token"}

Given that I can GET the /Prod/hello resource, I would not expect to see 405 Method Not Allowed for PUT, and 403 Forbidden is a… continue reading.

My Bref Makefile

In order to use Bref efficiently, I've developed a Makefile so that I don't have to remember all the various commands required.

PHP Architect: Serverless PHP With Bref, Part 1

I've written a two-part series on Serverless PHP on AWS Lambda using Matthieu Napoli's Bref for php[architect]. Part one has been published in the May 2019 issue and if you're not already a subscriber, you should be! If you just want to learn about Bref though, then my introduction to Bref is available for free, just for you!

Using img2lambda to publish your Serverless PHP layer

This interesting tweet by Clare Liguori came to my attention last week: This new img2lambda tool will take the layers of a Docker container and convert them to AWS layers for use in Lambda. I poked around with Clare's example and updated my lambda-php project in order to understand how it works. I also rewrote my runtime's bootstrap to make it clearer. The clever thing from my point of view is that you can build… continue reading.

Serverless PHP on AWS Lamda

Like, Simon Wardley, I think that serverless computing is an interesting space because the billing is granular (pay only when your code executes) and you don't need to worry about maintaining and provisioning servers or containers. So much so, that I maintain the Open Source PHP Runtime for Apache OpenWhisk which is available commercially as IBM Cloud Functions There are other serverless providers, and AWS Lambda is the market leader, but until recently PHP support… continue reading.
