“GET /index.php” 404 when dockerize Laravel app

Question

I tried to have a very minimal setup, to dockerize Laravel app. Even the nginx able to forward the request to Laravel container, I'm still getting GET /index.php" 404

C:\yocto\snapweb>docker-compose logs --follow laravel
Attaching to snapweb_laravel_1
laravel_1  | [23-Jul-2018 07:10:04] NOTICE: fpm is running, pid 1
laravel_1  | [23-Jul-2018 07:10:04] NOTICE: ready to handle connections
laravel_1  | 172.18.0.3 -  23/Jul/2018:07:14:01 +0000 "GET /index.php" 404

When I went inside laravel container, this is how it looks like. Seem fine to me.

Inside Laravel container

May I know what's wrong with my setup? Here's my minimalist Dockerfiles

Answer 1

PHP-FPM

I think you are missing the php-fpm.conf configuration file, mine looks just like a standard one with some changes:

• error_log = /proc/self/fd/2 allows you to use docker logs
• daemonize = no
• include=/etc/php/7.1/fpm/php-fpm.d/www.conf

www.conf which I include in the bottom of php-fpm.conf

standard one with changes:

• listen = 9000

Dockerfile:

Obviously I copy the php-fpm.conf and www.conf (I use php:7.1.14-fpm-jessie)

... install & cleanup steps
COPY php-fpm.conf /etc/php/7.1/fpm/php-fpm.conf
COPY www.conf /etc/php/7.1/fpm/php-fpm.d/www.conf

the end of Dockerfile for php-fpm looks like:

CMD ["php-fpm", "--fpm-config", "/etc/php/7.1/fpm/php-fpm.conf"]

---

NGINX

default which I copy in via Dockerfile:

server {
    listen 80 default_server;

    root /var/www/app/public;

    index index.html index.htm index.php;

    server_name _;

    charset utf-8;

    location = /favicon.ico { log_not_found off; access_log off; }
    location = /robots.txt  { log_not_found off; access_log off; }

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

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass pn-php-fpm:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    error_page 404 /index.php;

    location ~ /\.ht {
        deny all;
    }
}

NGINX's Dockerfile:

FROM nginx

RUN  echo "daemon off;" >> /etc/nginx/nginx.conf

COPY default /etc/nginx/conf.d/default.conf

# forward request and error logs to docker log collector
RUN ln -sf /dev/stdout /var/log/nginx/access.log \
    && ln -sf /dev/stderr /var/log/nginx/error.log

CMD ["nginx"]

Docker compose part

You need to share volumes when composing; what I mean, NGINX + php-fpm must be able to read your application's code

volumes:
  - wherever/your/code/is/on/host:/var/www/app

Note: this answer is WIP and I will edit / comment regularly in order to help OP.

Answer 2

Here's my very minimal setup, which makes Laravel workable in Docker. Previously, it doesn't work, because it didn't include the following line in Nginx container. (Although error happens in Laravel container)

root /var/www/html/public;

laravel/html (folder)

This folder is generated using the following command line. The command is executed in host machine.

docker run --rm -v $(pwd):/app -w /app composer/composer create-project --prefer-dist laravel/laravel html (Linux)
docker run --rm -v %cd%:/app -w /app composer/composer create-project --prefer-dist laravel/laravel html (Windows)

laravel/Dockerfile

FROM php:7.2.8-fpm-alpine3.7

COPY html /var/www/html

WORKDIR /var/www/html

RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer    

RUN composer install

RUN cp .env.example .env

RUN php artisan key:generate

RUN php artisan optimize

CMD ["php-fpm", "-F"]

nginx/default.conf

server {
    listen 443;
    ssl on;
    root /var/www/html/public;

    ssl_certificate /app/cert.pem;
    ssl_certificate_key /app/key.pem;

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

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass laravel:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }   
}

nginx/Dockerfile

FROM nginx:1.13.9-alpine

COPY . /app

RUN rm /etc/nginx/conf.d/default.conf
COPY default.conf /etc/nginx/conf.d/

docker-compose.yml

version: '2'
services:

  # Note, SSL cert (cert.pem and key.pem) is generated from cloudflare.
  nginx:
    build:
      context: ./nginx
      dockerfile: Dockerfile
    restart: always
    ports:
     - "2053:443"


  laravel:
    build:
      context: ./laravel
      dockerfile: Dockerfile
    restart: always

You can then access Laravel app using

https://localhost:2053/
