使用 websockets 通过 AWS API 网关接收请求并使用 AWS Lambda 调用 php 脚本

Question

Kinda lost on which services do I need to use, the idea is to build a server-less application using AWS services, here's a more detailed explanation on I'm looking for:

1. Client sends a request using websockets.
2. AWS API Gateway receives the request and invokes a lambda function.
3. The lambda function runs a php worker using Bref ( https://bref.sh/ ).
4. The php worker requires another php file which connects to a 3rd party using HTTP to request data (we have several of these so we're going to wake several workers probably for 1 single request from the client).
5. The data obtained is returned all the way back to the client.

So what I want to accomplish is to avoid using HTTP until point 5, now I'm totally lost in regards to this being doable or not, where do I host my php files? do I need to use AWS SQS to invoke the lambda function?

Any help would be appreciated guys, trying to ready through the official Amazon documentation is quite complex.

AWS Lambda Function is essentially a container that runs on a certain runtime.

Since PHP is not supported as an out-of-the-box runtime, you'll have to use a custom runtime.

Here's a great example by AWS for creating a Layer for PHP - https://github.com/aws-samples/php-examples-for-aws-lambda/tree/master/0.1-SimplePhpFunction

Another example, this one is for creating a custom runtime for PHP by using Docker - https://github.com/aws-samples/php-examples-for-aws-lambda/tree/master/0.7-PHP-Lambda-functions-with-Docker-container-images
