As a container-based deployment became an industry standard in our fast-paced developing world. So, this is how to run a MongoDB in Docker container, which ensures the management of the databases in a very easy way with portability, scalability, and low maintenance. The same thing, running the MongoDB in Docker is preferable by developers and system administrators because it removes system dependency issues and runs a consistent environment across various different platforms.
You can even use a MongoDB container, which helps you fire an actual MongoDB instance in seconds, so you can manage your database without installing MongoDB on your local machine or server. If you are developing locally or deploying in a production environment, containerized databases have made the scaling and backup processes far simpler.
Let’s learn together!
Deploying MongoDB in a Docker Container
Step 1: Install Docker
Before we go ahead, make sure you have Docker installed on your machine. You should run to verify that Docker is installed:
docker --versionOutput:
Docker version 24.0.5, build 1234567To install Docker, follow our guide to install Docker.

the latest updates directly in your inbox.
Step 2: Pull MongoDB Docker Image
Run the below command to pull the latest official MongoDB image.
docker pull mongo:latest Output:
latest: Pulling from library/mongo Digest: sha256:xxxxxxx Status: Downloaded newer image for mongo:latestThis command pulls the latest MongoDB container image from Docker Hub.
Step 3: Run MongoDB Container
Let’s start by creating and running a MongoDB container with persistent storage:
docker run -d \ --name mongodb-container \ -p 27017:27017 \ -e MONGO_INITDB_ROOT_USERNAME=admin \ -e MONGO_INITDB_ROOT_PASSWORD=password \ -v mongodb_data:/data/db \ mongo:latestExplanation:
- -d : Start a container in detached mode
- –name mongodb-container: Set a name to the container
- -p 27017:27017: Map MongoDB’s default port to the host machine
- -e MONGO_INITDB_ROOT_USERNAME=admin: We set root username
- -e MONGO_INITDB_ROOT_PASSWORD=password: Root password
- -v mongodb_data:/data/db: Creates a persistent volume for the MongoDB data
Run the following command to confirm MongoDB is running:
docker psOutput:
CONTAINER ID IMAGE STATUS PORTS NAMES a1b2c3d4e5f6 mongo:latest Up 10 minutes 0.0.0.0:27017->27017/tcp mongodb-container Step 4: Access MongoDB in Docker Container
Use the command to get the MongoDB shell inside the running container:
docker exec -it mongodb-container mongosh If successful, you must see the following:
test>You can now work with MongoDB in a similar way to how you would work with it in a full database setup.
Managing MongoDB Container with Docker Compose
Deploying MongoDB with Docker Compose Create a docker-compose.yml file:
version: '3.8' services: mongodb: image: mongo:latest container_name: mongodb-container ports: - "27017:27017" environment: MONGO_INITDB_ROOT_USERNAME: admin MONGO_INITDB_ROOT_PASSWORD: password volumes: - mongodb_data:/data/db volumes: mongodb_data: Run MongoDB with:
docker-compose up -dThis allows MongoDB to start automatically with the proper configurations.
How to Stop and Remove the MongoDB Container
To stop MongoDB:
docker stop mongodb-containerTo uninstall MongoDB and its data volume:
docker rm -v mongodb-containerHow to Manage MongoDB Containers Using CyberPanel
CyberPanel is a powerful web hosting control panel that simplifies Docker management. Here’s what CyberPanel does better with MongoDB in Docker:
- Docker Management at One-Click: CyberPanel has a GUI that allows anyone to deploy and manage MongoDB containers.
- Automated Backups: For your MongoDB, you can perform backups automatically to avoid data loss.
- Container Monitoring: View logs, resource usage, and container status directly from the CyberPanel dashboard
- Security and firewall management: Use iptables or similar tools to restrict unauthorized MongoDB access.
- Database Management Made Easy: With CyberPanel, you can set up and manage databases right through the integrated tools.
The integration of CyberPanel with MongoDB would enable you to manage databases and scale applications effectively.
FAQs: MongoDB in Docker Container
1. Why would you want to run MongoDB in a Docker container?
Running MongoDB in Docker container ensures portability, easy deployment, and isolation from the host system.
2. What is the role of Docker in organizing MongoDB instances?
Using Docker for MongoDB allows for quick and painless setup, scaling, and containerized environments that can be easily replicated.
3. Can I run multiple MongoDB containers on the same host?
Yes, but each container must expose a unique port mapping or run on a different network.
4. Does MongoDB in Docker lose data after a restart?
Data is removed when the container is removed (default behaviour). Docker volumes keep the data when starting containers up and down.
Conclusion: Using Docker to Deploy MongoDB Easily
If you’re looking to run MongoDB in a Docker container, Docker makes the process of setting up a database much easier and more manageable, as it also returns a consistent, scalable, and portable environment for the application. By implementing MongoDB in a containerized environment, you can improve efficiency and minimize setup complexity whether Docker Compose is your tool of choice for automation or CyberPanel provides advanced control over your DB.
