Atlas cluster creation basics in MongoDB - Mini Project: Build & Apply

Atlas cluster creation basics

📖 Scenario: You are setting up a MongoDB Atlas cluster to store data for a small online bookstore. This cluster will hold collections for books and authors.

🎯 Goal: Create a MongoDB Atlas cluster setup by defining the cluster configuration, adding a database user, and creating the initial collections for books and authors.

📋 What You'll Learn

Create a cluster configuration dictionary with specified parameters

Add a database user with username and password

Create collections named books and authors

Set cluster tier and region as specified

💡 Why This Matters

🌍 Real World

Setting up a MongoDB Atlas cluster is a common first step when building cloud-based applications that need a database.

💼 Career

Database administrators and backend developers often configure clusters and users in MongoDB Atlas to manage data securely and efficiently.

1

Create the cluster configuration dictionary

Create a dictionary called cluster_config with these exact entries: 'name': 'BookstoreCluster', 'tier': 'M0', 'region': 'US_EAST_1'.

MongoDB

# Create the cluster_config dictionary with name, tier, and region
# Your code here

Need a hint?

Use curly braces to create a dictionary and include the keys exactly as shown.

2

Add a database user

Add a dictionary called db_user with these exact entries: 'username': 'bookadmin' and 'password': 'securePass123'.

MongoDB

cluster_config = {
    'name': 'BookstoreCluster',
    'tier': 'M0',
    'region': 'US_EAST_1'
}
# Create the db_user dictionary with username and password
# Your code here

Need a hint?

Remember to use the exact keys and values for the user dictionary.

3

Create collections for books and authors

Create a list called collections containing the exact strings 'books' and 'authors'.

MongoDB

cluster_config = {
    'name': 'BookstoreCluster',
    'tier': 'M0',
    'region': 'US_EAST_1'
}
db_user = {
    'username': 'bookadmin',
    'password': 'securePass123'
}
# Create the collections list with 'books' and 'authors'
# Your code here

Need a hint?

Use square brackets to create a list with the two collection names as strings.

4

Complete the cluster setup dictionary

Create a dictionary called atlas_cluster that includes the keys 'config' with value cluster_config, 'user' with value db_user, and 'collections' with value collections.

MongoDB

cluster_config = {
    'name': 'BookstoreCluster',
    'tier': 'M0',
    'region': 'US_EAST_1'
}
db_user = {
    'username': 'bookadmin',
    'password': 'securePass123'
}
collections = ['books', 'authors']
# Create the atlas_cluster dictionary combining config, user, and collections
# Your code here

Need a hint?

Use the variable names exactly as given to build the final dictionary.
