I followed this giude to install wordpress in a container for test purposes but using mariadb and linux as a host. Here is my docker-compose:
version: '3.8'
services:
database:
image: mariadb
restart: always
environment:
MYSQL_ROOT_PASSWORD: password
MYSQL_DATABASE: wordpressDB
MYSQL_USER: user
MYSQL_PASSWORD: password
volumes:
- mysql:/var/lib/mysql
wordpress:
depends_on:
- database
links:
- database
image: wordpress:latest
restart: always
ports:
- '8000:80'
environment:
WORDPRESS_DB_HOST: database:3306
WORDPRESS_DB_USER: user
WORDPRESS_DB_PASSWORD: password
WORDPRESS_DB_NAME: wordpressDB
volumes:
- ./wordpress:/var/www/html
- ./wordpress/plugins:/var/www/html/wp-content/plugins
- ./wordpress/themes:/var/www/html/wp-content/themes
- ./wordpress/uploads:/var/www/html/wp-content/uploads
- ./wordpress/wp-content:/var/www/html/wp-content
volumes:
mysql: {}
For now I can access the wp-admin dashboard but can't update/install any plugin with error:
Could not create directory.
As mentioned here I've tried to change the permissions of the folders but with no success:
$ mkdir /var/www/html/wp-content/plugins
$ mkdir /var/www/html/wp-content/uploads
$ chown -R www-data:www-data /var/www
$ find /var/www/ -type d -exec chmod 0755 {} \;
$ find /var/www/ -type f -exec chmod 644 {} \;
Here is the output from ls -l

Where am I mistaken?
After a bit of digging, the problem is with this line that I added in my config.php that removed the missing FTP error when I started the container:
define('FS_METHOD', 'direct');
After that I tried many times to chown the directories of the site, with no success. Which is strange because I used the root account to change them. However they remained to group users.
In the end I added the www-data user to users and root (just in case) groups and that solved the problem.
usermod -a -G users www-data
usermod -a -G root www-data
Update
Another solution I found is instead of using a bind volume ./wordpress to use normal volume wordpress with read/write permissions. Here is the new docker-compose:
wordpress:
depends_on:
- database
links:
- database
image: wordpress:latest
restart: always
read_only: false
ports:
- '8000:80'
environment:
WORDPRESS_DB_HOST: database:3306
WORDPRESS_DB_USER: user
WORDPRESS_DB_PASSWORD: password
WORDPRESS_DB_NAME: database
volumes:
- wordpress:/var/www/html:rw
After the mentioned change the output of ls -l for the folders is like this:
-rw-r--r-- 1 www-data www-data 405 Feb 6 2020 index.php
-rw-r--r-- 1 www-data www-data 19915 Jan 1 2021 license.txt
-rw-r--r-- 1 www-data www-data 7345 Dec 29 2020 readme.html
-rw-r--r-- 1 www-data www-data 7165 Jan 21 01:37 wp-activate.php
drwxr-xr-x 1 www-data www-data 2668 May 12 23:49 wp-admin

-rw-r--r-- 1 www-data www-data 44994 Apr 4 18:34 wp-login.php
-rw-r--r-- 1 www-data www-data 8509 Apr 14 2020 wp-mail.php
-rw-r--r-- 1 www-data www-data 21125 Feb 2 00:10 wp-settings.php
-rw-r--r-- 1 www-data www-data 31328 Jan 27 21:03 wp-signup.php
-rw-r--r-- 1 www-data www-data 4747 Oct 8 2020 wp-trackback.php
-rw-r--r-- 1 www-data www-data 3236 Jun 8 2020 xmlrpc.php
Now wordpress updates/installs plugins and the update of wordpress itself is working flawlessly.
