How to Run MongoDB on Docker

MongoDB is a popular NoSQL database that is widely used in modern applications. Docker is a popular containerization platform that simplifies the deployment and management of applications. In this article, we will walk through the steps required to run MongoDB on Docker. We will cover everything from installing Docker to running and managing MongoDB containers.

Installing Docker

The first step is to install Docker on your machine. Docker is available for Windows, macOS, and Linux. You can download the Docker installer from the official Docker website. Once you have downloaded the installer, follow the instructions to install Docker on your machine.

Creating a Docker Network

Before we can create a MongoDB container, we need to create a Docker network. A Docker network is a virtual network that allows containers to communicate with each other. To create a Docker network, open a terminal and run the following command:

docker network create mongo

This will create a Docker network named 'mongo'.

Running MongoDB on Docker

Now that we have Docker installed and a Docker network created, we can run a MongoDB container. To run a MongoDB container, open a terminal and run the following command:

docker run -d --name mongo-container --network mongo -p 27017:27017 mongo

This command will start a MongoDB container in detached mode with the name 'mongo-container'. The container will be connected to the 'mongo' Docker network and the MongoDB default port 27017 will be exposed to the host machine.

Managing MongoDB Containers

Once the MongoDB container is running, we can manage it using Docker commands. Here are some useful commands:

• To view a list of running containers, run the following command:

docker ps

• To stop a running container, run the following command:

docker stop mongo-container

• To start a stopped container, run the following command:

docker start mongo-container

• To remove a container, run the following command:

docker rm mongo-container

In this article, we have covered the steps required to run MongoDB on Docker. We started by installing Docker, creating a Docker network, and running a MongoDB container. We also covered some basic Docker commands for managing containers. With Docker, running MongoDB becomes much easier and more manageable.
