I'm trying to set up Symfony 3 in Docker on a Windows machine with NGINX and PHP-FPM. At the moment, I get a 502 bad gateway error. I changed the FPM port from 9000 to 8000 because on my host, port 9000 is already in use by a hyper-v service vmms.exe. I don't know if it's related.
docker-compose.yml
version: "3"
services:
nginx:
build: ./nginx
volumes:
- ./symfony:/usr/shared/nginx/html
ports:
- "80:80"
- "443:443"
environment:
- NGINX_HOST=free-energy.org
depends_on:
- fpm
fpm:
image: php:fpm
ports:
- "8000:8000"
# It seems like FPM receives the full path from NGINX
# and tries to find the files in this dock, so it must
# be the same as nginx.root
volumes:
- ./symfony:/usr/shared/nginx/html
Dockerfile NGINX:
FROM nginx:1.13.7-alpine
# Change Nginx config here...
RUN rm /etc/nginx/conf.d/default.conf
ADD ./default.conf /etc/nginx/conf.d/
EXPOSE 80
EXPOSE 443
default.conf override NGINX:
server {
listen 80;
server_name free-energy.org;
# this path MUST be exactly as docker-compose.fpm.volumes,
# even if it doesn't exist in this dock.
root /usr/share/nginx/html;
location / {
try_files $uri /index.php$is_args$args;
}
location ~ ^/.+\.php(/|$) {
fastcgi_pass fpm:8000;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
Could you please check php-fpm container? As I remember, the php-fpm default port is 9000, not 8000. Change port mapping from inside container from 8000 to 9000
ports: - "8000:9000"
Or if it already to use on your host you can expose the port only between containers.
expose: - "9000"
With the answer of 0TshEL_n1ck the 502 error was solved. I still got 'File not found' in the browser and a related error log in NGINX 'FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream'.
Here is the configuration that turned out to work. The key things that needed to change:
These points came to light after using the NGINX configuration from the Symfony docs located at https://symfony.com/doc/current/setup/web_server_configuration.html
Here's the code that worked.
docker-compose.yml:
version: "3"
services:
nginx:
build: ./nginx
volumes:
- ./symfony:/var/www/symfony
ports:
- "80:80"
- "443:443"
depends_on:
- fpm
fpm:
image: php:fpm
ports:
- "9000"
volumes:
- ./symfony:/var/www/symfony
NGINX configuration default.conf:
server {
listen 80;
server_name free-energy.org, www.free-energy.org;
root /var/www/symfony/public;
location / {
# try to serve file directly, fallback to index.php
try_files $uri /index.php$is_args$args;
}
location ~ ^/index\.php(/|$) {
fastcgi_pass fpm:9000;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
# When you are using symlinks to link the document root to the

fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;
# Prevents URIs that include the front controller. This will 404:

We will guess so a week, try to use this: /docker-compose.yml
version: "2"
services:
nginx:
build: "./docker/nginx/"
container_name: "nginx-free-energy"
volumes_from:
- php-fpm
restart: always
ports:
- "80:80"
php-fpm:
image: php:7.1-fpm
container_name: "php-fpm-free-energy"
volumes:
- ./src/free-energy.org:/var/www/free-energy.org
restart: always
expose:
- "9000"
/docker/nginx/Dockerfile
FROM nginx
COPY config/free-energy.conf /etc/nginx/conf.d/free-energy.conf
RUN rm /etc/nginx/conf.d/default.conf
RUN usermod -u 1000 www-data
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
/docker/nginx/config/free-energy.conf (for symfony3 app)
server {
listen 80;
server_name www.free-energy.org free-energy.org;
root /var/www/free-energy.org/web;
location / {
# try to serve file directly, fallback to app.php
try_files $uri /app.php$is_args$args;
}
# PROD
location ~ ^/app\.php(/|$) {
fastcgi_pass php-fpm-free-energy:9000;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
# When you are using symlinks to link the document root to the

fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;

location ~ \.php$ {
return 404;
}

access_log /var/log/nginx/free-energy.org_access.log;
}
After start, you need to add 127.0.0.1 free-energy.org to your /etc/hosts file for resolving the host, and your app will live on the /src/free-energy.org (entry point is - /src/free-energy.org/web/app.php)
