Volume mount when setting up Wordpress with docker - wordpress

Question

Quickstart: Compose and WordPress proposes the following docker-compose.yml
version: '3.3'
services:
db:
image: mysql:5.7
volumes:
- dbdata:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: somewordpress
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: wordpress
wordpress:
depends_on:
- db
image: wordpress:latest
ports:
- "8000:80"
restart: always
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: wordpress
volumes:
dbdata:
For persisting database data, a volume is created:
The docker volume db_data persists any updates made by Wordpress to the database.
but nothing is mentioned about the wordpress container...
Questions:
should I follow the same approach and create volumes for the wordpress container, in order to persist the data that are going to be added (by posts, uploads, themes)?
If yes, which paths / directories should I point to?

Answer 1

Maybe I've found something...
volumes:
- wp-content:/var/www/html/wp-content
According to this article:
...wp-content contains all user-supplied content. Basically anything you can upload to your site ends up here. That doesn’t include anything you write, mind you. Those things are stored in the WordPress database.
However, as long as you have both the database and your wp-content folder, you can always get your site back, even if everything else was lost.
This is also applied here: Setting up WordPress with Docker

MYSQL_DATABASE: wordpress

ports:
