Permissions problems in docker container

[neoranger]

Hi, im tried to use bludit with docker compose but when i have to config Bludit in the admin page i get a permissions error in content folder.

My compose:

services:
  bludit:
    image: bludit/docker:latest
    container_name: bludit_cms
    ports:
      - '9200:80'
    volumes:
      - ./bludit-content:/var/www/bludit/bl-content/
#      - ./bludit-content:/usr/share/nginx/html/bl-content
      - ./bludit-plugins:/usr/share/nginx/html/bl-plugins
#      - ./bludit-plugins:/var/www/bludit/bl-plugins
      - ./bludit-themes:/usr/share/nginx/html/bl-themes
#      - ./bludit-themes:/var/www/bludit/bl-themes/
    restart: always

If i use nginx directory i can't install plugins or themes or active default theme. If is use /var directory i can activate the default theme but i can't install new themes.
