You need to copy files to use Nginx and PHP.

Copy docker/ folder and docker-compose.yaml to your CodeIgniter4 project root. https://github.com/codeigniter4/devkit/pull/37/files#diff-079c8a90be414928ae24510a296a33243d0c17372a82a91876d033137b089544R14

Got it! I rarely use Docker but let me know when this is ready for review and I will take it for a spin. I should be a good Guinea pig for the instructions given my noobiness

@kenjis I'm using docker in my development and here is the my setup.

I have folder docker with development and production folders, so I suggest to move development Dockerfile to docker/development and have an opportunity to add production folder if it's needed in future for users.

I started also to build Dockerfile with nginx & php-fpm separated, but there is no customisable options, if we want to customise something during the development it's a pain.

So I started my journey to find suitable image with php-fpm & nginx in one image with customisable options and in the end I found it. Here is the link to image: https://github.com/tiredofit/docker-nginx-php-fpm

It works perfectly for development and even for production.

My Dockerfile for development looks now like:

FROM tiredofit/nginx-php-fpm:8.0-alpine_3.16

ENV STAGE DEVELOPMENT
ENV TIMEZONE Europe/Bratislava
ENV NGINX_WEBROOT /app/public
ENV PHP_MEMORY_LIMIT 1G
ENV PHP_ENABLE_PDO_SQLITE TRUE
ENV PHP_ENABLE_REDIS TRUE

WORKDIR /app

COPY . .

I'm enabling ENV variables directly in Dockerfile and I can overwrite them or add another in docker-compose if needed.

My docker-compose looks like:

version: "3.7"
