Docker - chown: changing ownership of '/data/db': Operation not permitted

I am trying to run my application using Docker and here is my yml file content to run the mongo container.

 services:
   mongodb:
    image: mongo:3.4
    #    ports:
    #        - "27017:27017"
    volumes:
      - ./data/mongo:/data/db
    restart: always

And getting this error in contianer: (Saw this error after running docker logs command)

chown: changing ownership of '/data/db': Operation not permitted

The host has ./data/mongo folder and here are the details.

drwxrwxrwx  2 nfsnobody nfsnobody 4096 May 11 23:13 mongo

I tried to run this on the host as suggested in one of the forums.

sudo chgrp 1000 ./data/mongo

Not sure how this would help to solve the issue because the error we get is insdide the container folder not the one from host, anyway i tried..

But got this response :

chgrp: changing group of ‘mongo’: Operation not permitted

How to solve this issue? is there any solution other than "chgrp"? Thank you.

Here is the full docker-compose.yml file

## You can generate a custom docker compose file automatically on http://reportportal.io/download (Step 2)

## This is example of Docker Compose for ReportPortal
## Do not forget to configure data volumes for production usage

## Execute 'docker-compose -p reportportal up -d --force-recreate'
## to start all containers in daemon mode
## Where:
##      '-p reportportal' -- specifies container's prefix (project name)
##      '-d' -- enables daemon mode
##      '--force-recreate' -- forces re-recreating of all containers

Mongo startup script changes ownership on files in /data/configdb and /data/db if ran as root. Try running it as nfsnobody (the owner of local ./data/mongo) to skip this step:

services:
  mongodb:
    user: "nfsnobody" # insert either uid or name of the user
