MongoDB Docker Compose Setup

This project provides a simple and efficient way to deploy a MongoDB instance using Docker Compose, with automated setup scripts and scheduled backups.

Features

• Easy Deployment: Spin up a MongoDB container with a single command using Docker Compose.
• Automated Setup: Installs Docker, Docker Compose, and cron for scheduling backups.
• Backup Automation: Creates daily backups (saved for one week) of the MongoDB database with timestamped archives.

Installation

1. Clone the repository:

   git clone https://github.com/your-username/mongodb-docker-compose.git
   cd mongodb-docker-compose

2. Create a .env file to store sensitive environment variables:

   echo "MONGO_INITDB_ROOT_USERNAME=your_username" > .env
   echo "MONGO_INITDB_ROOT_PASSWORD=your_password" >> .env

3. Make the scripts executable:

   chmod +x start.sh backup.sh

4. Run the setup script:

   ./start.sh

   This will:

   • Install Docker, Docker Compose, and cron (if not already installed).
   • Start the MongoDB container in the background.
   • Schedule daily backups at 3 AM.

Usage

• Connect to MongoDB: Connect to localhost:27017 with the credentials specified in the .env file.

• Manual Backup: Run the backup script to create a backup archive:

  ./backup.sh

  Backups are stored in the backup/ directory with a timestamp (e.g., mongodb_backup_2025-06-07_03-00-00.archive).

• Stop the Container:

  docker-compose down

Configuration

You can customize the setup by modifying the .env file. Available environment variables:

• MONGO_INITDB_ROOT_USERNAME: MongoDB init root username
• MONGO_INITDB_ROOT_PASSWORD: MongoDB init root password
• BACKUP_SCHEDULE: Cron schedule for backups (default: 0 3 * * * for 3 AM daily)

Backup Restoration

To restore a backup, use the mongorestore command. Example:

docker exec -it mongodb mongorestore --archive=/backup/mongodb_backup_2025-06-07_03-00-00.archive
