Mongo Docker

Dockerfile and scripts to setup a production ready Mongo container with user authentication and SSL configuration

Example project https://github.com/duluca/lemon-mart-server

Key features:

• Uses the official mongo docker image as the base
• Enables configuring an application database and user/password
• Creates default admin user, if it doesn't already exist
• Scripts to deploy this image to your own AWS ECS cluster

Setup

• Define a .env file at the root of the project and set the MongoDB admin passowrd. Do NOT commit this file.

MONGO_INITDB_ROOT_USERNAME=admin_user
MONGO_INITDB_ROOT_PASSWORD=admin_password
MONGODB_APPLICATION_DATABASE=app_db_name
MONGODB_APPLICATION_USER=app_user
MONGODB_APPLICATION_PASS=app_password

Quick Start

• npm install to get dependencies
• npm run docker:build to build the Docker image
• npm run docker:debug to build and debug the Docker image

Note: To persist data you must link /data/db to a location where the data will persist if this image is stopped. See the yml file below as an example.

• Use npm run docker:runMount to enable data persistance with this image

Sample Usage with docker-compose

Mounting to AWS EFS

If you're using AWS ECS as your container host, then your data needs to reside on AWS EFS. Setting this up correctly, so you can easily mount your '/data/db' volume to EFS can be complicated. Check out this step-by-step guide that will help you do just that, including how to create an AWS ECS Cluster from scratch.

TODO

• Enable SSH capability: https://docs.mongodb.com/manual/tutorial/configure-ssl/
