Use Docker Compose to quickly deploy PHP applications
Introduction:
Docker is an open source containerization platform that can integrate applications and their Dependencies are packaged into a separate container and run in isolation. Docker Compose is a tool for defining and running multi-container Docker applications. This article will introduce how to use Docker Compose to quickly deploy PHP applications, with specific code examples.
1. Preparation
Before you begin, you need to ensure that Docker and Docker Compose have been installed. Please follow the corresponding steps to install according to your operating system type.
2. Create a Docker Compose file
Create a file named docker-compose.yml in the project root directory, and write the following content in the file:
version: '3' services: web: image: php:7.4-apache volumes: - ./src:/var/www/html ports: - "80:80" networks: - mynetwork db: image: mysql:8.0 environment: - MYSQL_ROOT_PASSWORD=your_password - MYSQL_DATABASE=your_database volumes: - ./data:/var/lib/mysql networks: - mynetwork networks: mynetwork:
In the above example, we defined two services: web and db.
3. Write PHP application
Create a folder named src in the project root directory and write your PHP application code in this folder.
4. Start the application
Open the terminal, switch to the project root directory, and run the following command to start the application:
docker-compose up -d
Wait a moment, Docker will automatically download all the required image and launch your application.
5. Access the application
Visit http://localhost in the browser, you should be able to see the running results of your PHP application.
Conclusion:
By using Docker Compose, we can quickly deploy PHP applications and ensure the repeatability and portability of the application. I hope this article can help you get started with Docker Compose quickly and achieve good results in practical applications. I wish you a happy use!
