How to deploy a PHP project in Docker?

Deploying a PHP project in Docker typically involves the following steps:

1. Create a Dockerfile in the root directory of the project to define the building rules for the Docker image.
2. Specify a base image in the Dockerfile: Choose a suitable PHP base image, such as php:7.4-apache.
3. Add project files to container: Use the COPY instruction to copy files from the PHP project to the specified directory in the container.
4. Install project dependencies: Use the RUN instruction to execute commands in the container, for example, installing PHP dependencies with Composer.
5. Expose port: Define the port that the container listens on using the EXPOSE command, for example 80.
6. Start the web server: Use CMD command to define the command to be executed when the container starts, for example, starting the Apache server.
7. Create a Docker image: Build a Docker image using the docker build command, for example docker build -t my-php-app .
8. To run a Docker container: Use the docker run command to start the container and map its port to a specified port on the host machine, for example docker run -p 8080:80 my-php-app.

The steps above are just basic procedures. In actual deployment, you may need to configure environment variables, create databases, etc. Specific deployment steps should be adjusted according to the requirements of the project.
