Hello everyone,

I am trying out Percona Server for MongoDB. My current deployment is a Mongo community edition Docker container, which all of my other services can talk to. I have a Docker service defined within a docker-compose.yaml file like this, which works perfect for Mongo community:

```auto
version: '3.9'
services:
  mongo:
    image: mongo:6.0.2
    container_name: mongo
    env_file:
      - ~/projects/env.list
    networks:
      - local
    ports:
      - 27017:27017
    restart: always
    volumes:
      - /mnt/files:/data/db

```

Now, when I want to use this same volume path for testing with Percona containers, I get errors after starting up the Percona containers via:

```auto
docker run --name percona-test -v /mnt/files:/data/db:rw -d percona/percona-server-mongodb:latest

```

The container error logs that this produces are as follows:

```auto

```

I don’t get these read-only errors when launching with regular Mongo community images, but for some reason these `Percona Server for MongoDB` images are giving read-only folder issues.

Can anyone advise?

Thank you

Hello,

I wanted to update everyone that the main change I had to make is to run the container as root. This is not something that I have to do with the community edition; however, the documentation does say to run as root or sudo so I missed this detail.

Hopefully this helps someone else. Thanks for the cool tooling Percona team, I am looking forward to using it!

Hi @jimbo ,

Thanks for the update and yes it needs to run as root user.  
Here is the documentation [link](https://docs.percona.com/percona-server-for-mongodb/5.0/install/docker.html).

Regards,
