There are instances when you want to create MongoDB instance in Docker to use in production or in local/internal. We came across this requirement where we were using MongoDB Atlas for production but wanted to use MongoDB docker in our local/internal/dev environment. Mongo Atlas uses SSL connection so we want to keep our local consistent with production environment. In this post, I am going to explain the process of creating Mongo Docker instance with valid SSL certificate and replicating same behaviour of MongoDB Atlas.

Docker For MongoDB

This project is to created docker image of MongoDB with a user. Read my post about this project

Pre-requisites

1. Install docker in your machine from https://docs.docker.com/engine/installation/
2. Run docker in your machine
3. Make entry in your /etc/hosts file like 127.0.0.1 localhost ry-dev.herokuapp.com

Steps to Create Docker Container

1. Go to folder which contains DockerFile
2. Run docker build -t mongo . (mongo is the tag name which will be used in next step)
3. Run docker run -d -p 27017:27017 --mount source=mongodb,target=/data/db --mount source=configdb,target=/data/configdb --name mongoDB mongo:latest (mongoDB is the container name which can be used for referring container in any other command)

Other Useful Commands

• Check status of your container by docker ps -a
• Check logs of the container by docker logs -f <CONTAINER ID OR NAME>
• Remove any container docker rm <CONTAINER ID OR NAME>
• Get shell in container docker exec -it <CONTAINER ID OR NAME> bash
• Command line connection to MongoDB mongo --ssl --host ry-dev.herokuapp.com --port 27017 --username mongodb --password mymongopass --authenticationDatabase mydatabase
