Laravel

Walk through deploying a Laravel application on auto scaled Kubernetes cluster.

Goal: Deploy PHP app that will auto scale based on average CPU utilization across deployed instance.

install Laravel with composer

composer global require "laravel/installer"

create new project

composer create-project --prefer-dist laravel/laravel laravel-project

Docker

For the purpose of this demo I've built a public docker image and pushed to my Docker account. Dockerfile adds laravel app into a lightweight alpine image.

build application docker image

docker build -t crunchgeek/laravel-project .

push image to the repository

docker push crunchgeek/laravel-project

Kubernetes

load environment variables

kubectl create -f env-app.yaml 
kubectl create -f env-php.yaml 
kubectl create -f env-nginx.yaml 

deploy application

kubectl create -f deployment.yaml 

expose service

this step requires a different service yaml depending where the app is being deployed:

minikube

kubectl create -f service.node.yaml 

open browser

minikube service laravel-project

Google Cloud

kubectl create -f service.yaml 

Amazon AWS

kubectl create -f service.aws.yaml 

deploy auto scaler

kubectl create -f autoscaler.yaml

That's it! Now the infrastructure will auto adjust itself to the app resources demand.
