Set correct nextcloud permissions for local storage access

[33Fraise33]

I'm running Nextcloud in Docker through Ansible:

- name: setup nextcloud docker container
  docker_container:
    name: nextcloud
    image: nextcloud:latest
    networks:
      - name: fraise_network
        ipv4_address: "{{ docker_network.nextcloud }}"
    purge_networks: yes
    volumes:
      - "/data/nextcloud/www:/var/www/html"
      - "/data:/data"
    user: 33:1003
    env:
      NEXTCLOUD_ADMIN_USER: gianni
      NEXTCLOUD_ADMIN_PASSWORD: "{{ nextcloud_admin_password }}"
      NEXTCLOUD_TRUSTED_DOMAINS: "domain"
      MYSQL_DATABASE: nextcloud
      MYSQL_USER: nextcloud
      MYSQL_PASSWORD: "{{ db_nextcloud_password }}"
      MYSQL_HOST: "{{ docker_network.nextcloud_db }}"
    restart: yes
    restart_policy: always
    state: started
    pull: true

I would like to be able to write into my /data directory through the external storage access app.

A group was created on the Docker host with the name 'data' where I added in the http user (33 uid on arch) and changed the folder permissions of all folders to 775 and owner: root:data.

When adding the external storage I see "You don't have permission to upload or create files here".
After giving a certain folder temporary 777 permissios I see that nextcloud still writes as http:http.

Is it possible to change this when running in docker?

i use this dockerfile since a few months

FROM nextcloud:fpm-alpine

ARG UID
ARG GID

RUN apk --no-cache add shadow &&
rm -rf /var/cache/apk/* &&
OUID=$(id -u www-data) &&
OGID=$(id -g www-data) &&
usermod -u $UID www-data &&
groupmod -g $GID www-data &&
find / -group $OGID -exec chgrp -h www-data {} ; &&
find / -user $OUID -exec chown -h www-data {} ;

This is what i am running.
@Flow86 Unfortunately yours didn't work for me, so heres my Dockerfile:

FROM nextcloud:20-fpm-alpine

ARG UID=1003
ARG GID=1003

RUN apk --no-cache add shadow && \
rm -rf /var/cache/apk/* && \
OUID=$(id -u www-data) && \
OGID=$(id -g www-data) && \
usermod -u $UID www-data && \
groupmod -g $GID www-data ;

RUN OGID=$(id -g www-data) && \
find / -group $OGID -exec chgrp -h www-data {} \;

RUN OUID=$(id -u www-data) && \
find / -user $OUID -exec chown -h www-data {} \;
