Docker - LEMP Stack Dev Environment

This is a ready-to-fire LEMP Stack development environment. All services created using official images, you can reach them via those links:

MySql - PhpMyAdmin - Nginx - PHP Official Image - Version of php-fpm used in this stack

How to use

First of all, you need to go through Docker Installation but I suppose you already did that so you can follow steps below.

• To start up MySql and PhpMyAdmin services, navigate to /db/ folder and type docker-compose up -d.
• Now navigate to /front/ folder and type the same command docker-compose up -d. It could take several seconds php-fpm service to startup.

And now you can use PhpMyAdmin from http://localhost:8888/ to create, delete and whatever you want to do with your MySql database (username: root password: 1234).

Edit files in /front/html/ directory and see the changes from http://localhost:80/ for index.php and http://localhost:80/index.html for index.html.

When you type docker ps command, you should see your containers like this:

CONTAINER ID	IMAGE	COMMAND	CREATED	STATUS	PORTS	NAMES
[some random id]	nginx	"/docker-entrypoint.…"	[some seconds ago]	[some seconds]	0.0.0.0:80->80/tcp, :::80->80/tcp	nginx
[some random id]	php:fpm	"docker-php-entrypoi…"	[some seconds ago]	[some seconds]	9000/tcp	php-fpm
[some random id]	phpmyadmin	"/docker-entrypoint.…"	[some seconds ago]	[some seconds]	0.0.0.0:8888->80/tcp, :::8888->80/tcp	phpmyadmin
[some random id]	mysql	"docker-entrypoint.s…"	[some seconds ago]	[some seconds]	3306/tcp, 33060/tcp	mysql

How It works?

Services have some requirements to startup, those requirements are specified in environment rest of them are mostly optional.

Be aware that in docker-compose.yml files we set container_name vars to easen communication between containers. With this technique, we can refer to containers like [container_name]:[port] as in /front/default.conf file.

MySql & PhpMyAdmin

• MYSQL_ROOT_PASSWORD should be the same in both mysql and phpmyadmin services and both container_name in mysql and PMA_HOST in phpmyadmin variables should be the same.
• restart: always is optional. If some kind of exception happens, those services will restart itself.
• Both services should be in the same network so they can communicate to each other easily, via their container names & ports.
• Volumes in mysql is also optional. If you create and specify a volume, mysql won't lose It's stored data.

Nginx & Php-fpm

• Both services should be in the same network so they can communicate to each other easily, via their container names & ports.
• phpfpm service must be in the same network with mysql so you can make sql queries easily.
• You should bind your project root directory to /var/www/html as volume. In this case, we set the volume like this ./html:/var/www/html for phpfpm service and ./html:/usr/share/nginx/html for nginx service.
• For php-fpm service, we wrote a command to install mysqli extension. If you're not gonna use mysqli or use a different php extension, you can edit this line.
• We created a config file to use in nginx container and bind It as a volume ./default.conf:/etc/nginx/conf.d/default.conf.
