Great writeup! This is going to help me out a ton.

After reading through the article and looking at your example repo, I think the directory structure at the top of this article would look more like this (i.e. dedicated docker and src directories):

Project
│
├── docker
├──── docker-compose.yml
│
├──── database/
│   ├──── Dockerfile
│   └──── data/
│
└──── php-fpm/
│   └──── Dockerfile
│
├──── nginx/

│   └──── nginx.conf

└──── logs/

├── src

For those which rather want to use postgresql instead of mariadb.

# docker/database/Dockerfile
FROM postgres:latest

ENV POSTGRES_USER <your user>
ENV POSTGRES_PASSWORD <your password>
EXPOSE 3306

And I had to add

RUN apk add --no-cache bash

in php-fpm dockerfile (due to this warning: env: can't execute 'bash': No such file or directory).

Greatly explained setup, thanks! How to downgrade php to 7.4? I tried replacing the first line in docker/php-fpm/Dockerfile to FROM php:7.4-fpm-alpine and fired up my container but didn't work. docker exec -it docker_php-fpm_1 php -v outputs PHP 8.0.9 (cli). Any thoughts?

Hi there!
I am a beginner developer. I downloaded your project from your repo for learning purposes.
I use Maker Bundle to automatically create an user.
When I run the command (docker and mysql are already running):
php bin/console make:migration

this error is shown several times in a row:
SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution

Could be possible that this bundle is unable to know where my database is running? How could I solve this issue?

Any help would be welcome. Thanks for your excellent article and cheers.

You should connect to you docker terminal to run the above command... It should be something like docker exec -it docker_container_name ash. Your docker_container_name should be listed in docker ps -a

Please have a look at the Gitlab Repo mentioned in the article. There you will find the wait-for-it.sh. You have to add it to your code. It's not included in the article.

UPDATE 31.07.2021
if someone having the problem with error from apline:
/bin/sh: Operation not permitted
or
*some_command* returned a non-zero code: 2

just change first line in docker/php-fpm/Dockerfile to:
FROM php:8.0-fpm-alpine3.13

They mess something in update 3.14, changing to older version fixes that

Great article!

Would be great if I was able to enter container bash by running

docker-compose exec nginx bash
Enter fullscreen mode Exit fullscreen mode

Is it possible to update Dockerfile to enable that?

Great tutorial !
Just one thing, remember to add "wait-for-it.sh" in "php-fpm" directory ;)
