Overview

This docker-compose.yml file creates a MongoDB container with authentication and binds port 27017 to the host machine. It also creates a data volume for persisting the database files.

Prerequisites

Docker and Docker Compose installed on your machine.

Usage

1. Clone or download the repository to your local machine.
2. Navigate to the directory containing the docker-compose.yml file.
3. Run the following command to start the MongoDB container:

docker-compose up -d

This will start the container in the background and print the container ID.

4. Verify that the container is running:

docker ps

This should display a list of running containers on your machine, including the MongoDB container.

5. To stop the container, run:

docker-compose down

This will stop and remove the container.

Configuration

The mongodb_container service in the docker-compose.yml file is configured with the following options:

• image: specifies the Docker image to use for the container. In this case, the latest version of the official MongoDB image.
• environment: sets environment variables for the container. In this case, sets the MongoDB root user credentials.
• ports: maps the container's port 27017 to the host machine's port 27017.
• volumes: creates a data volume for persisting the MongoDB data.

The volumes section of the docker-compose.yml file creates a named volume mongodb_data_container for storing the MongoDB data. This allows the data to persist even if the container is removed or recreated.
