PHP example

A basic PHP application runs inside AWS Lambda.

You can package this PHP application into Docker image, push to ECR, and deploy to Lambda, ECS/EKS, or EC2.

The application can be deployed in an AWS account using the Serverless Application Model. The template.yaml file in the root folder contains the application definition.

The top level folder is a typical AWS SAM project. The app directory is the nginx configuration with a Dockerfile.

FROM public.ecr.aws/awsguru/php:82.2023.3.11.1 AS builder
COPY --from=composer /usr/bin/composer /usr/local/bin/composer

COPY app /var/task/app
WORKDIR /var/task/app

RUN composer install --prefer-dist --optimize-autoloader --no-dev --no-interaction

FROM public.ecr.aws/awsguru/php:82.2023.3.11.1
COPY --from=public.ecr.aws/awsguru/aws-lambda-adapter:0.7.2 /lambda-adapter /opt/extensions/lambda-adapter
COPY --from=builder /var/task /var/task

# config files
ADD nginx/conf/nginx.conf      /opt/nginx/conf/nginx.conf
ADD php/php.ini                /opt/php/php.ini
ADD php/etc/php-fpm.conf       /opt/php/etc/php-fpm.conf
ADD php/php.d/extensions.ini   /opt/php/php.d/extensions.ini

Pre-requisites

The following tools should be installed and configured.

• AWS CLI
• SAM CLI
• Docker

Deploy to Lambda

Navigate to the sample's folder and use the SAM CLI to build a container image

$ sam build

This command compiles the application and prepares a deployment package in the .aws-sam subdirectory.

To deploy the application in your AWS account, you can use the SAM CLI's guided deployment process and follow the instructions on the screen

$ sam deploy --guided

Please take note of the container image name. Once the deployment is completed, the SAM CLI will print out the stack's outputs, including the new application URL. You can use curl or a web browser to make a call to the URL

$ curl https://xxxxxxxxxx.execute-api.us-west-2.amazonaws.com/Prod/

Run the docker locally

We can run the same docker image locally, so that we know it can be deployed to ECS Fargate and EKS EC2 without code changes.

$ docker run -d -p 8080:8080 {ECR Image}

Use curl to verify the docker container works.

$ curl localhost:8080/
