How to allow remote connections from mongo docker container

I am using the official mongodb docker container. I want to connect to the mongodb container from my host machine on port 27017. I ran the container with these ports exposed

-p 27017:27017

I am not able to connect (connection refused) and I believe its because the mongo conf file is not configured to allow remote connections. How can I configure it to allow? The official container does not have vi/nano installed to modify the image.

I am able to connect to mongodb from another container by creating a link - however this is not my wish

My answer to another question. How to enable authentication on MongoDB through Docker?

Here's what I did for the same problem, and it worked.

  1. Run the mongo docker instance on your server

    docker run -d -p 27017:27017 -v ~/dataMongo:/data/db mongo

  2. Open bash on the running docker instance.

    docker ps

    CONTAINER IDIMAGE COMMAND CREATED STATUS PORTS NAMES

    b07599e429fb mongo "docker-entrypoint..." 35 minutes ago Up 35 minutes 0.0.0.0:27017->27017/tcp musing_stallman

    docker exec -it b07599e429fb bash
root@b07599e429fb:/#

    Reference- https://github.com/arunoda/meteor-up-legacy/wiki/Accessing-the-running-Mongodb-docker-container-from-command-line-on-EC2

  3. Enter the mongo shell by typing mongo.

    root@b07599e429fb:/# mongo

  4. For this example, I will set up a user named ian and give that user read & write access to the cool_db database.

    > use cool_db

> db.createUser({
    user: 'ian',
    pwd: 'secretPassword',
    roles: [{ role: 'readWrite', db:'cool_db'}]
})

    Reference: https://ianlondon.github.io/blog/mongodb-auth/ (First point only)

  5. Exit from mongod shell and bash.

  6. Now run the mongo docker with auth enabled.

    docker run -d -p 27017:27017 -v ~/dataMongo:/data/db mongo mongod --auth

  7. I was able to connect to the instance running on a Google Cloud server from my local windows laptop using the below command.

    mongo <ip>:27017/cool_db -u ian -p secretPassword
