# MongoDB Sharding Cluster Setup
This guide explains how to set up a MongoDB sharding cluster using Docker Compose and how to use it in a Node.js application.
## Prerequisites
- Docker
- Docker Compose
- Node.js
## Setup
### Step 1: Start the Docker Containers
Run the following command to start the MongoDB containers:
```sh
docker-compose up -d
```
### Step 2: Customize Docker Compose
You can customize the Docker Compose file to suit your needs. For example, you can change the memory limits, CPU limits, and volume paths.
#### Example for Windows
```yaml
volumes:
- F:/Database/MongoDBCluster/configs1:/data/db
```
#### Example for Linux
```yaml
volumes:
- /mnt/f/Database/MongoDBCluster/configs1:/data/db
```
### Step 3: Initiate the Cluster
#### For Linux/MacOS
First, make the script executable:
```sh
chmod +x initiate-cluster.sh
```
Then, run the script:
```sh
./initiate-cluster.sh
```
#### For Windows
Run the batch script:
```sh
initiate-cluster.bat
```
This script will set up the config server replica set, the shard replica set, and add the shard to the cluster.
### Step 4: Using the Cluster in a Node.js Application
To connect to the MongoDB sharding cluster from a Node.js application, use the following connection string:
```javascript
const { MongoClient } = require('mongodb');
async function main() {
const uri = "mongodb://localhost:30000";
const client = new MongoClient(uri);
try {
await client.connect();
console.log("Connected to MongoDB sharding cluster");
// ... your application code ...
} finally {
await client.close();
}
}
main().catch(console.error);
```
Replace `// ... your application code ...` with your actual application logic.
### Step 5: Stopping the Cluster
To stop the MongoDB containers, run:
```sh
docker-compose down
```
This will stop and remove the containers.
