Port 3306

[R-QualiPdf]

I am trying to get this running on Windows.
This is the first time I am using Docker, so please bare with me.

(1) For starters, the stable version (19.4) of Node wouldn't install, instead I had to use version 17; edited in .env.
#WORKSPACE_NODE_VERSION=stable
WORKSPACE_NODE_VERSION=v17.9.1

(2) I noticed there are three applications that use the same port 3306. However, the mariadb won't start.

D:\xampp\htdocs\EQEmuAllakhazamClone\laradock>docker-compose up -d nginx mariadb workspace
[+] Running 3/4

• Container laradock-workspace-1 Started 1.2s
• Container laradock-php-fpm-1 Started 2.3s
• Container laradock-nginx-1 Started 3.7s
• Container laradock-mariadb-1 Starting 3.7s
  Error response from daemon: Ports are not available: exposing port TCP 0.0.0.0:3306 -> 0.0.0.0:0: listen tcp 0.0.0.0:3306: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted.

If I change the port, e.g. to 3307, it will start all four containers, but then, the website says "Impossible to connect to mariadb".
