Nginx (pronounced “engine x”) is a web server and reverse proxy server that can also function as a load balancer, HTTP cache, and mail proxy. It is known for its high performance, stability, and low resource usage.

PHP-FPM (FastCGI Process Manager) is an alternative implementation of PHP FastCGI. It is a process manager that allows PHP to handle requests in a more efficient manner than traditional CGI-based implementations.

This article will introduce how to run Nginx and PHP FPM in a Docker Container.

Prerequisite

  1. Docker Engine installed on OS, linux / mac / windows

Create one example php file

i will create index.php file

<?php phpinfo();

Create Dockerfile

Creating nginx-php fpm dockerfile based on php:8.2-fpm-buster image. we should have add nginx package and supervisor package for running two process (nginx and php-fpm) 

FROM php:8.2-fpm-buster

RUN apt update -y
RUN apt install nginx supervisor -y
RUN mkdir -p /var/log/php-fpm/

COPY default /etc/nginx/sites-enabled/default
COPY supervisord.conf /etc/supervisor/conf.d/supervisord.conf
COPY index.php /var/www/html/index.php

RUN ln -sf /dev/stdout /var/log/nginx/access.log \
    && ln -sf /dev/stderr /var/log/nginx/error.log

CMD [ "/usr/bin/supervisord" ]

Create necessary files

supervisord.conf

[supervisord]
nodaemon=true

[program:nginx]
command=/usr/sbin/nginx -g "daemon off;"
autostart=true
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/nginx/access.log
stderr_logfile=/var/log/nginx/error.log
stdout_logfile_maxbytes = 0
stderr_logfile_maxbytes = 0

[program:php-fpm]
command=/usr/local/sbin/php-fpm --nodaemonize
autostart=true
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/php-fpm/access.log
stderr_logfile=/var/log/php-fpm/error.log
stdout_logfile_maxbytes = 0
stderr_logfile_maxbytes = 0

default

server {
         listen       80;
         server_name  _;
         root         /var/www/html/;

         access_log /var/log/nginx/access.log;
         error_log  /var/log/nginx/error.log error;
         index index.html index.htm index.php;

         location / {
                      try_files $uri $uri/ /index.php$is_args$args;
         }

         location ~ \.php$ {
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass localhost:9000;
            fastcgi_index index.php;
            include fastcgi.conf;
    }
}

something like this

❯ tree
.
├── Dockerfile
├── default
├── index.php
└── supervisord.conf

Build Dockerfile to Image

Almost done, let’s build the image

docker build -t ghcr.io/man20820/nginx-phpfpm:test .

Run the Container

Finally we can run the container with this command

docker run -d --name nginx-php -p 80:80 ghcr.io/man20820/nginx-phpfpm:1

Access the webpage

We can access on localhost port 80

Check the container logs

docker logs nginx-php --follow

Congratulation!
