Combining PHP-fpm with nginx in one dockerfile [closed]

Nginx installation is much easier than PHP so it should be easier for you to install Nginx into a ready-to-use official PHP image. Here is an example of a Dockerfile showing how your goal can be reached with an example of installing a few PHP extensions:

FROM php:7.2-fpmRUN apt-get update -y \    && apt-get install -y nginx# PHP_CPPFLAGS are used by the docker-php-ext-* scriptsENV PHP_CPPFLAGS="$PHP_CPPFLAGS -std=c++11"RUN docker-php-ext-install pdo_mysql \    && docker-php-ext-install opcache \    && apt-get install libicu-dev -y \    && docker-php-ext-configure intl \    && docker-php-ext-install intl \    && apt-get remove libicu-dev icu-devtools -yRUN { \        echo 'opcache.memory_consumption=128'; \        echo 'opcache.interned_strings_buffer=8'; \        echo 'opcache.max_accelerated_files=4000'; \        echo 'opcache.revalidate_freq=2'; \        echo 'opcache.fast_shutdown=1'; \        echo 'opcache.enable_cli=1'; \    } > /usr/local/etc/php/conf.d/php-opocache-cfg.iniCOPY nginx-site.conf /etc/nginx/sites-enabled/defaultCOPY entrypoint.sh /etc/entrypoint.shCOPY --chown=www-data:www-data . /var/www/mysiteWORKDIR /var/www/mysiteEXPOSE 80 443ENTRYPOINT ["/etc/entrypoint.sh"]

The nginx-site.conf file contains your Nginx http host configuration. The example below is for a Symfony app:

server {    root    /var/www/mysite/web;    include /etc/nginx/default.d/*.conf;    index app.php index.php index.html index.htm;    client_max_body_size 30m;    location / {        try_files $uri $uri/ /app.php$is_args$args;    }    location ~ [^/]\.php(/|$) {        fastcgi_split_path_info ^(.+?\.php)(/.*)$;        # Mitigate https://httpoxy.org/ vulnerabilities        fastcgi_param HTTP_PROXY "";        fastcgi_pass 127.0.0.1:9000;        fastcgi_index app.php;        include fastcgi.conf;    }}

The entrypoint.sh will run Nginx and php-fpm on container startup (otherwise only php-fpm will be started as the default action of the official PHP image):

#!/usr/bin/env bashservice nginx startphp-fpm

Of course, this is not the best way from the best practice perspective, but I hope this is the answer to your question.

Update:

If you get the permission denied error on the entrypoint.sh file, check that this file has the executable permission if you're building from under Linux, or add the RUN chmod +x /etc/entrypoint.sh to the Dockerfile if you're under Windows (all files from under Windows are copied without the executable permission to the container).

If you're running under Google Cloud Run, keep in mind that Nginx startups before PHP and it does that much quicker than PHP. This leads to the issue that when Cloud Run sends the first request, it comes at the moment when Nginx is already initialized, but PHP-FPM is not yet and Cloud Run request fails. To fix that, you should change your entrypoint to startup PHP-FPM before Nginx:

#!/usr/bin/env shset -ephp-fpm -Dnginx -g 'daemon off;'

This script is tested under Alpine Linux only. I guess it should also work on other images. This script runs php-fpm first in the background, and then Nginx without exiting. In this way, Nginx always starts listening to ports after PHP-FPM is initialized.

You should deploy two container, one with fpm, the other with nginx, and you should link them.Even though you can use supervisor in order to monitore multiple processes within the same container, Docker philosophy is to have one process per container.

Something like:

docker run --name php -v ./code:/code php:7-fpmdocker run --name nginx -v ./code:/code -v site.conf:/etc/nginx/conf.d/site.conf --link php nginx:latest

With site.conf with

server {    index index.php index.html;    server_name php-docker.local;    error_log  /var/log/nginx/error.log;    access_log /var/log/nginx/access.log;    root /code;    location ~ \.php$ {        try_files $uri =404;        fastcgi_split_path_info ^(.+\.php)(/.+)$;        fastcgi_pass php:9000;        fastcgi_index index.php;        include fastcgi_params;        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;        fastcgi_param PATH_INFO $fastcgi_path_info;    }}
