Looking at the mongo Dockerfile :

• a user mongodb is created
• /data/db is created and protected for mongodb:mongodb

So try and make sure to start your container with that user:

docker run --user mongodb ...

If that is not working, then fallback to the original docker run command (which runs as root by default) and define run.sh (that needs to be copied in your own image) which will:

• do the right chown -R mongodb:mongodb /data/db
• call entrypoint.sh mongod

That is:

docker run ... run.sh

That would be an approach similar to issue 7198 (Make uid & gid configurable for shared volumes) .
