Cannot connect after docker install

[TheCarpetMerchant]

Describe the bug
Going into the install tab and trying to connect to the xgp db doesn't work.
The php error is "Cannot asign requested address" when specifying the port, and "No such file or directory" without, both at Core/Database.php line 77.

To Reproduce
Steps to reproduce the behavior:

1. git clone
2. docker-compose up
3. localhost:80 in a web browser
4. Enter the informations localhost:33060, root, root, xgp.
5. Connection doesn't work.

Trying with localhost:3306 leads to the same problem. phpmyadmin and mysql workbench can both connect to the server perfectly fine.

Desktop (please complete the following information):

• OS: Windows 10
• Browser : Firefox (latest)

Server (please complete the following information):

• PHP Version: Don't know how to get it.
• MySQL Version: 5.7.43
