Step-By-Step process Deploy PHP Application Using The Docker Compose

Here is the detailed steps to deploy the PHP application using Docker Compose.

Step 1: Launch an Instance

• Go to AWS Console and login to AWS Console with your credentials
• Now Go to EC2 Dashboard and launch an instance

• Now connect with terminal

Step 2: Install Docker

• Now install docker with following command

sudo yum -y install docker

Start and enable docker. Without starting docker it cannot be start the docker and cannot execute docker commands

sudo systemctl start  docker
sudo systemctl enable docker
sudo systemctl status docker

Step 3: Install Docker-Compose

Now install docker-compose because we are dealing with docker compose without docker-compose we can run docker-compose file. By using following commands we can install docker-compose

sudo curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose

Now change permissions to docker-compose by using following commands

sudo chmod +x /usr/local/bin/docker-compose

+x means we are giving execution permissions only to docker-compose.

Step 4: Create Dockerfile

• Now create a dockerfile by using following file. In this inside docker file we are providing dockerfile script.
• By using dockerfile we are pulling php application. Create dockerfile by using following commands

sudo vi Dockerfile or sudo vi dockerfile

# Use PHP 8.0 as the base image
FROM php:8.0-apache
WORKDIR /var/www/html
COPY . /var/www/html
RUN docker-php-ext-install pdo_mysql mysqli
RUN a2enmod rewrite
EXPOSE 80
CMD ["apache2-foreground"]

Step 5: Create Docker-compose file

Now create docker-compose file by using following commands

sudo vi docker-compose.yml

version: '3.3'
services:
  php:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "8080:80"
    volumes:
      - .:/var/www/html
    depends_on:
      - mysql
    environment:
      MYSQL_HOST: mysql
      MYSQL_DATABASE: mydatabase
      MYSQL_USER: myuser
      MYSQL_PASSWORD: mypassword
  mysql:
    image: mysql:5.7
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
      MYSQL_DATABASE: mydatabase
      MYSQL_USER: myuser
      MYSQL_PASSWORD: mypassword
    ports:
      - "3306:3306"
    volumes:
      - mysql_data:/var/lib/mysql
volumes:
  mysql_data:

Step 6: Execute Docker commands

Build Docker Image: Run the following command to build the Docker image for the PHP application.

docker-compose build

Start Docker Containers: After building the image, start the Docker containers using the following command.

docker-compose up

Check Docker Containers: We can check docker container list. Ensure that all Docker containers are running by running the following command.

docker-compose ps

We can check logs by using following commands

docker-compose logs php

Access PHP Application: Once the containers are up and running, access the PHP application in your web browser. Now go to EC2 dashboard and copy public IP Address of EC2 instance and browse it along with port number 8080

Stop Docker Containers: When done, stop the Docker containers by pressing Ctrl + C in the terminal or execute following command:

docker-compose down

In the domain of web development, PHP continues to be a widely utilized programming language, fueling various websites, web applications, and APIs. As the complexity of PHP projects increases, so do the difficulties related to managing dependencies, conditions, and deployment processes, Docker Compose arises as a strong solution for addressing these difficulties by improving the containerization and coordination of PHP applications. This guide focuses on investigating best practices for utilizing Docker Compose with PHP applications. We’ll begin by defining key terminologies connected with Docker and Docker Compose, laying the foundation for understanding their role in containerizing PHP projects. From that point, we’ll frame a step-by-step process for containerizing PHP applications utilizing Docker Compose, ensuring versatility, consistency, and simplicity of organization.

Toward the end of this guide, you’ll have an exhaustive comprehension of how to use Docker Compose successfully for PHP projects. Whether you’re a carefully prepared PHP developer hoping to smooth out your deployment work processes or a novice anxious to saddle the force of containerization, this guide will furnish you with the knowledge and tools to prevail in managing PHP applications with Docker Compose. We should dive into and investigate the universe of Docker Compose for PHP applications together!
