bitnami/mongodb docker container fails to start because 'permission denied' on config file

I’m on Ubuntu 20.04.5 LTS trying to create a docker container for a mongo database

the command i’m using is:

docker-compose up -d --build

the docker-compose.yml file contains:

version: '2'
services:
  ptmdocker-mongodb:
    build:
      context: ptmdocker-mongodb/
      dockerfile: Dockerfile
    environment:
      - MONGODB_ROOT_PASSWORD=xx
      - MONGODB_USERNAME=xx
      - MONGODB_PASSWORD=xx
      - MONGODB_DATABASE=xx
    ports:
      - '27017:27017'
    volumes:
      - /home/administrator/mongo_live_data:/bitnami/mongodb

and the Dockerfile contains:

FROM bitnami/mongodb:latest
VOLUME /backups
USER root
RUN ["apt-get", "update"]
RUN ["apt-get", "install", "-y", "nano"]
EXPOSE 27017

I expect the container to start, and I expect to have an empty database. But after a few seconds the docker container goes down, in the logs I find following error:

mongodb 15:20:35.01

Error opening config file: Permission denied
try '/opt/bitnami/mongodb/bin/mongod --help' for more information

I’m mapping the db folder inside the container to a folder on the host:

/home/administrator/mongo_live_data

Maybe there is an issue for permissions on this folder? Any ideas how I can fix this?

    More a workaround then a solution, but I installed a new ubuntu instance, this time I used ubuntu 20.04.2 instead of 20.04.5.

    After installing docker and docker-compose I could create the mongo docker container with none of the mentioned permissions issues.

    (its fixed for me, but I'm still not sure if its because of the ubtuntu version or if I did something wrong on my first ubuntu install...)

    From https://hub.docker.com/r/bitnami/mongodb:

    NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID 1001

    To find user with UID 1001:

    $ cat /etc/passwd | grep 1001
