Set up docker-compose with nginx missing snippets/fastcgi-php.conf - docker

Question

I am trying to set up a new docker-compose file.
version: '3'
services:
webserver:
image: nginx:latest
container_name: redux-webserver
# working_dir: /application
volumes:
- ./www:/var/www/
- ./docker/nginx/site.conf:/etc/nginx/conf.d/default.conf
ports:
- "7007:80"
Currently it is very simple. But I copy the following config:
# Default server configuration
#
server {
listen 7007 default_server;
listen [::]:7007 default_server;
root /var/www;
# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html;
server_name example;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/=404;
}
location /redux {
alias /var/www/Redux/src;
try_files $uri #redux;
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_param SCRIPT_FILENAME $request_filename;
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
}
}
location #redux {
rewrite /redux/(.*)$ /redux/index.php?/$1 last;
}
# pass PHP scripts to FastCGI server
#
location ~ \.php$ {
include snippets/fastcgi-php.conf;
#fastcgi_split_path_info ^(.+\.php)(/.+)$;
# With php-fpm (or other unix sockets):
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
#fastcgi_index index.php;
# With php-cgi (or other tcp sockets):
# fastcgi_pass 127.0.0.1:9000;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
location ~ /\.ht {
deny all;
}
}
But now when I try to start it with docker-compose run webserver I get the following error:
2019/07/20 08:55:09 [emerg] 1#1: open() "/etc/nginx/snippets/fastcgi-php.conf" failed (2: No such file or directory) in /etc/nginx/conf.d/default.conf:59
nginx: [emerg] open() "/etc/nginx/snippets/fastcgi-php.conf" failed (2: No such file or directory) in /etc/nginx/conf.d/default.conf:59
I understand it does not find the file fastcgi-php.conf. But why is this? Shouldn't that file be included in the standart nginx installation?

Answer 1

/etc/nginx/snippets/fastcgi-php.conf is in nginx-full package, but the image nginx:latest you used did not install nginx-full package.
To have it, you need to write your own dockerfile base from nginx:latest & install nginx-full in it:
Dockerfile:
FROM nginx:latest
RUN apt-get update && apt-get install -y nginx-full
docker-compose.yaml:
version: '3'
services:
webserver:
build: .
image: mynginx:latest
Put Dockerfile & docker-compose.yaml in the same folder then up it.
Additional, if you do not mind use other folk's repo(means not official), you can just search one from dockerhub, e.g. one I find from dockerhub (schleyk/nginx-full):
docker run -it --rm schleyk/nginx-full ls -alh /etc/nginx/snippets/fastcgi-php.conf
-rw-r--r-- 1 root root 422 Apr 6 2018 /etc/nginx/snippets/fastcgi-php.conf

Answer 2

You are trying to use a docker compose config that does not account for your trying to load fastcgi / php specific options.
You can use another image and link it to your web server like:
volumes:
- ./code:/code
- ./site.conf:/etc/nginx/conf.d/site.conf
links:
- php
php:
image: php:7-fpm
volumes:
- ./code:/code
