Creating buckets and uploading objects in GCP - Try It Yourself

Creating buckets and uploading objects

📖 Scenario: You are working on a cloud project where you need to store files safely. Google Cloud Storage lets you create buckets to hold your files (called objects). You will create a bucket and upload a file to it.

🎯 Goal: Build a Google Cloud Storage bucket and upload a text file into it using Python code.

📋 What You'll Learn

Create a bucket named exactly my-test-bucket-12345

Create a text file named hello.txt with content Hello, Cloud!

Upload the hello.txt file to the bucket

Use the Google Cloud Storage Python client library

💡 Why This Matters

🌍 Real World

Cloud storage buckets are used to store and organize files in the cloud for websites, apps, and backups.

💼 Career

Cloud engineers and developers often create and manage storage buckets and upload files programmatically for scalable cloud applications.

1

Create a bucket named my-test-bucket-12345

Write Python code to create a Google Cloud Storage bucket named my-test-bucket-12345 using the storage.Client() and client.create_bucket() methods.

GCP

# Your code here to create the bucket named 'my-test-bucket-12345'

Hint

Use storage.Client() to create a client, then call create_bucket() with the bucket name.

2

Create a text file named hello.txt with content Hello, Cloud!

Write Python code to create a file named hello.txt and write the text Hello, Cloud! into it.

GCP

from google.cloud import storage

client = storage.Client()
bucket_name = 'my-test-bucket-12345'
bucket = client.create_bucket(bucket_name)

# Create 'hello.txt' file with content 'Hello, Cloud!'
# Your code here

Hint

Use Python's open() function with mode 'w' to write text to a file.

3

Upload the hello.txt file to the bucket

Write Python code to upload the local file hello.txt to the bucket my-test-bucket-12345 using the bucket.blob() and blob.upload_from_filename() methods.

GCP

from google.cloud import storage

client = storage.Client()
bucket_name = 'my-test-bucket-12345'
bucket = client.create_bucket(bucket_name)

with open('hello.txt', 'w') as file:
    file.write('Hello, Cloud!')

# Upload 'hello.txt' to the bucket
# Your code here

Hint

Create a blob object with bucket.blob('hello.txt') and upload the file with upload_from_filename().

4

Set the bucket's default storage class to STANDARD

Write Python code to set the bucket's default storage class to STANDARD using the bucket.default_storage_class attribute and update the bucket with bucket.update().

GCP

from google.cloud import storage

client = storage.Client()
bucket_name = 'my-test-bucket-12345'
bucket = client.create_bucket(bucket_name)

with open('hello.txt', 'w') as file:
    file.write('Hello, Cloud!')

blob = bucket.blob('hello.txt')
blob.upload_from_filename('hello.txt')

# Set bucket storage class to STANDARD
# Your code here

Hint

Change the default_storage_class attribute and call patch() to apply changes.

Practice

1. What is the main purpose of creating a bucket in Google Cloud Storage?

easy

A. To manage user permissions

B. To organize and store files in the cloud

C. To create databases

D. To run virtual machines

Solution

1. Step 1: Understand what a bucket is

   A bucket is a container in cloud storage used to hold files or objects.

2. Step 2: Identify the purpose of buckets

   Buckets help organize and store files safely in the cloud for easy access and management.

3. Final Answer:

   To organize and store files in the cloud -> Option B

4. Quick Check:

   Bucket = Storage container [OK]

Hint: Buckets hold files in cloud storage, not run machines [OK]

Common Mistakes:

• Confusing buckets with virtual machines
• Thinking buckets create databases
• Mixing buckets with user permission tools

2. Which command correctly creates a new bucket named my-bucket in Google Cloud Storage using the gcloud tool?

easy

A. gcloud storage buckets create my-bucket

B. gcloud create bucket my-bucket

C. gsutil mb gs://my-bucket

D. gcloud storage create-bucket my-bucket

Solution

1. Step 1: Recall the gcloud syntax for bucket creation

   The correct syntax is gcloud storage buckets create [BUCKET_NAME].

2. Step 2: Match the command with the correct syntax

   gcloud storage buckets create my-bucket matches the correct syntax exactly.

3. Final Answer:

   gcloud storage buckets create my-bucket -> Option A

4. Quick Check:

   gcloud storage buckets create = create bucket [OK]

Hint: Use 'gcloud storage buckets create' to make buckets [OK]

Common Mistakes:

• Using 'gcloud create bucket' which is invalid syntax
• Confusing gsutil command with gcloud syntax
• Adding hyphens incorrectly in command

3. What will be the result of running this command?
gsutil cp file.txt gs://example-bucket/

medium

A. Downloads file.txt from example-bucket

B. Deletes file.txt from local storage

C. Creates a new bucket named example-bucket

D. Uploads file.txt to the example-bucket in Google Cloud Storage

Solution

1. Step 1: Understand the gsutil cp command

   The gsutil cp command copies files between local and cloud storage.

2. Step 2: Analyze the command arguments

   It copies file.txt from local to the bucket gs://example-bucket/, uploading the file.

3. Final Answer:

   Uploads file.txt to the example-bucket in Google Cloud Storage -> Option D

4. Quick Check:

   gsutil cp local-to-bucket = upload [OK]

Hint: gsutil cp localfile gs://bucket = upload file [OK]

Common Mistakes:

• Thinking cp deletes local files
• Assuming it creates buckets automatically
• Confusing upload with download direction

4. You tried to upload a file using gsutil cp myfile.txt gs://my-bucket/ but got an error saying the bucket does not exist. What is the most likely fix?

medium

A. Run the command with sudo

B. Rename the file to match the bucket name

C. Create the bucket first using gsutil mb gs://my-bucket

D. Delete the file and try again

Solution

1. Step 1: Understand the error cause

   The error means the bucket my-bucket does not exist in cloud storage.

2. Step 2: Fix by creating the bucket

   You must create the bucket first using gsutil mb gs://my-bucket before uploading files.

3. Final Answer:

   Create the bucket first using gsutil mb gs://my-bucket -> Option C

4. Quick Check:

   Bucket missing? Create it first [OK]

Hint: Create bucket before upload to avoid errors [OK]

Common Mistakes:

• Trying to upload without bucket creation
• Changing file name instead of bucket
• Using sudo unnecessarily

5. You want to create a bucket named data-archive in the us-central1 region with versioning enabled to keep old versions of files. Which sequence of commands achieves this?

hard

A. gsutil mb -l us-central1 gs://data-archive && gsutil versioning set on gs://data-archive

B. gcloud storage buckets create data-archive --location=us-central1 && gcloud storage buckets update data-archive --versioning-enabled

C. gcloud storage buckets create data-archive --region=us-central1 && gcloud storage buckets enable-versioning data-archive

D. gsutil create bucket data-archive us-central1 && gsutil enable versioning gs://data-archive

Solution

1. Step 1: Create bucket with location using gsutil

   The command gsutil mb -l us-central1 gs://data-archive creates the bucket in the correct region.

2. Step 2: Enable versioning on the bucket

   The command gsutil versioning set on gs://data-archive turns on versioning to keep old file versions.

3. Final Answer:

   gsutil mb -l us-central1 gs://data-archive && gsutil versioning set on gs://data-archive -> Option A

4. Quick Check:

   Create bucket + enable versioning with gsutil [OK]

Hint: Use gsutil mb and gsutil versioning set on for versioned buckets [OK]

Common Mistakes:

• Using wrong flags like --region instead of -l
• Trying to enable versioning with wrong commands
• Mixing gcloud and gsutil commands incorrectly
