+# Running MongoDB in Docker
+
+<img src="mongo.png"  width="255"> <img src="docker.png"  width="150">
+
+This guide outlines the steps to run MongoDB in a Docker container with an attached volume. This allows you to persist the data outside the container and preserve it even when the container is removed.
+
+## Prerequisites
+
+- Docker installed on your machine
+
+## Step 1:
+
+1. Replace `<CONTAINER_NAME>` and `<VOLUME_NAME>` with the desired container name and volume name.
+
+2. Run MongoDB in a Docker container with the volume attached:
+
+   ```
+   docker run -d --name <CONTAINER_NAME> -p 27017:27017 -v <VOLUME_NAME>:/data/db mongo:latest
+   ```
+
+   This command starts a MongoDB container named `<CONTAINER_NAME>`, maps port `27017` of the container to port `27017` on the host machine, and attaches the volume called `<VOLUME_NAME>` to the container's `/data/db` directory.
+
+## Step 2:
+
+### 1. Open [Studio3T](https://studio3t.com/) app to access the mongodb
+
+### 2. Connect to the mongodb using the following URI:
+
+```
+mongodb://localhost:27017
+```
+
+### 3. Add a name for the database.
+
+### 4. Create a new database.

+
+### 5. To select the database:
+
+```
+use my_db
+```
+
+This command switches to the `my_db` database. If the database doesn't exist, MongoDB will create it automatically when you start using it.
+
+### 6. Create a Collection in the selected database
+
+```
+db.createCollection("my_collection")
+```
+
+This command creates a collection named `my_collection` within the `my_db` database.
+

+
+### 7. Insert documents into the collection:
+
+```
+db.mycollection.insertOne({
+"name": "John Doe",
+"age": 30,
+"email": "[email protected]",
+"address": {
+   "street": "123 Main St",
+   "city": "New York",
+   "state": "NY",
+   "zipcode": "10001"
+},
+"interests": ["programming", "reading", "traveling"]
+})
+```
+
+This command inserts multiple documents into the `my_collection` collection with corresponding `name`, `age`, `email`, `address`, `interests` values.
+
+### 8. Find documents in the collection:
+
+```
+db.my_collection.find()
+```
+
+This command retrieves all documents from the `my_collection` collection and displays them.
+
+### 9. Delete the created collection:
+
+```
+db.mycollection.drop()
+```
