PHP FPM

Wordpress Docker

• Initial Configuration for PHP-FPM (FastCGI)

  • Create the docker image configuration file Dockerfile for WordPress container in the path described below via the terminal:

    mkdir -p rootInception/srcs/requirements/wordpress/Dockerfile

  • Fill in the Dockerfile for WordPress so that it can configure a docker image that will be executed later as shown below:

    FROM debian:bullseye
    RUN apt update && apt upgrade -y && apt install -y php-fpm vim
    ENTRYPOINT ["tail", "-f", "/dev/null"]

    👉🏼 The final tail -f command will be used only initially while we build the machine, and it will be discarded later according to future modifications since this command is prohibited by the project requirements.

    👉🏼 PHP-FPM is a FastCGI, meaning it is responsible for executing .php files and transforming the output of these files into HTML pages in response to a request made to them by a server, such as NGINX.

  • Update the docker-compose.yml file by adding a service for WordPress, so that when executed, it can compose the WordPress container as well, as shown below:

    version: "3.8"
    
    services:
      nginx:
        build: requirements/nginx/.
        container_name: nginx
        ports:
          - "80:80"
      wordpress:
        build: requirements/wordpress/.
        container_name: wordpress

    👉🏼 These are the minimum configurations for PHP-FPM to run inside the container. We now need to start the WordPress container, enter it, and copy the content of some default files created during the PHP-FPM installation in the system, which should be modified for the project's functionality.

    👉🏼 This file copying step can be done in two ways: automatically or manually. I will proceed with the automatic mode, but if it becomes difficult to understand how everything works, I suggest doing it manually.

  Manual Mode: Entering the Container
