Detailed explanation of PHP cloud native technology application

Cloud native technology is a set of practices and technologies suitable for cloud computing environments, aiming to improve the portability, scalability and elasticity of applications. Cloud-native technologies in PHP include: Docker: Create and run containers. Kubernetes: Manage and orchestrate containers. Istio: Service mesh that provides secure connections and traffic management. Helm: Deploy and manage Kubernetes applications.

Detailed explanation of PHP cloud native technology application

What is cloud native technology?

Cloud native technology is a set of best practices and technologies applicable to cloud computing environments, aiming to improve the portability, scalability and resiliency of applications.

Cloud Native Technologies in PHP

PHP is widely used to develop cloud native applications and the following technologies are available:

• Docker: For creating and running lightweight, portable containers.
• Kubernetes: Used to manage and orchestrate containers.
• Istio: Used for service mesh, providing secure connections and traffic management between microservices.
• Helm: Used to deploy and manage Kubernetes applications.

Practical case

Using Kubernetes to build PHP microservices

Step 1: Create a Docker image

FROM php:8.0-fpm

COPY . /var/www/html

WORKDIR /var/www/html

RUN composer install

CMD ["php", "-S", "0.0.0.0:8000", "-t", "public", "index.php"]

Step 2: Create the Kubernetes manifest file

apiVersion: apps/v1
kind: Deployment
metadata:
  name: php-app
  labels:
    app: php-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: php-app
  template:
    metadata:
      labels:
        app: php-app
    spec:
      containers:
      - name: php-app
        image: registry.example.com/php-app:latest
        ports:
        - containerPort: 8000

Step 3: Deploy the Kubernetes application

kubectl apply -f deployment.yaml

Use Istio to protect PHP microservices

Step 1: Install Istio

istioctl install --set profile=demo

Step 2: Create a service mesh

istioctl create serviceentry php-app \
  --address=php-app \
  --port=8000

Step 3: Test Istio Authentication and Authorization

istioctl proxy-config secret inject \
  --namespace default \
  --service php-app

Now your PHP application can be managed through Kubernetes and get security and traffic management capabilities through Istio .
