Docker PHP environment

Local docker environment for PHP development with components:

• PHP 7.3
• Nginx
• MySQL 8
• Redis

Features

We'll follow important docker rule - one service per container. Also, we'll mount docker volumes to keep code and data on our host machine and use it in containers, so our containers will work for "read-only" purpose and can be stopped, deleted or replaced without losing data.

Folders structure

.
├── containers         # Docker containers
│   ├── mysql
│   ├── nginx
│   ├── php
|   └── redis
├── logs               # Different logs 
└── www                # Project files

Execute

Just run

docker-compose up -d

Test build

Open the browser and go to localhost:8080. You'll see:

Check MySQL connection, run localhost:8080/db.php

Known issues

In new versions of PHP and MySQL you may see an error:

SQLSTATE[HY000] [2002] Connection refused

Just connect to a MySQL container

docker exec -it docker-php bash 

Then connect to mysql from command line

mysql -uroot -psecret hellodb

And run commands:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'secret';
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'secret';
ALTER USER 'default'@'%' IDENTIFIED WITH mysql_native_password BY 'secret';
