How to: Use Docker to setup WordPress

This is my first attempt to use Docker to self host a Wordpress blog. I have used the following docker images:

The official Wordpress image
The official Nginx image
The official Maria DB image
jwilder’s docker-gen image. This is used to configure the nginx proxy
jrcs’s letsencrypt-nginx-proxy-companion image. This is used to generete/renew my SSL certificated through Let’s Encrypt

I have chosen to store the persistent data into named volumes. The named volumes are:

certs to store the SSL certificates
figura.im-html to store all the Wordpress html related content
figura.im-db to store the Maria DB data

Since I am using docker compose v2, I am required to use this Nginx template.

Any feedback on my approach si welcome. There is always space for improvement!

Below is my docker compose yml file.

version: "2"

services:

  nginx:
    image: nginx
    container_name: nginx

      - "/etc/nginx/vhost.d"
      - "/usr/share/nginx/html"
      - certs:/etc/nginx/certs:ro

  nginx-gen:
