Creating a Docker image with Ubuntu, NGINX and PHP

Set up

• Create a new directory and change into it
• Create a new directory called ‘webroot’
• Create a new directory called ‘config’
• Create ‘webroot/phpinfo.php’

<?php
  phpinfo();
?>

• Create a file called config/default

server {
        listen 80 default_server;
        listen [::]:80 default_server;

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.php index.html index.htm index.nginx-debian.html;

        server_name _;


        location ~* \.php$ {
                fastcgi_pass unix:/run/php/php7.4-fpm.sock;
                include         fastcgi_params;
                fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
                fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
        }

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }


}

• Create a file called Dockerfile

# Pinning to Ubuntu 20.04. v22 has some qwearks right now.

RUN sed -i 's/cgi.fix_pathinfo=1/cgi.fix_pathinfo=0/g' /etc/php/7.4/fpm/php.ini

# Copy config files into container

# Start services and hang out
ENTRYPOINT service php7.4-fpm start && service nginx start && bash
