Using Local! You can create very quickly a simple wordpress on localhost with a domain website.local. You can also backup your site and drag-n-drop into Local for using locally. However, Local are not always working with the custom themes.

WP basic without backup

Make a folder name mysite containing,
1mysite
2|-- docker-compose.yml  # main file
3|-- backup              # contains backup files using AIO WP Migration plugins
4|-- plugins             # contains plugins
5|-- themes              # contains templates
6|-- wordpress           # main site's sources
In the docker-compose.yml
1version: '3.1'

3services:
