Azure blob storage – get began with examples!


Azure Blob Storage, a Microsoft object storage resolution, offers optimized cloud storage for storing unstructured knowledge. Unstructured knowledge could possibly be textual content, pictures, or binary knowledge. Blob Storage is good for storing information immediately in an online browser. Moreover, it may also be used to retailer knowledge for backup, archiving, and knowledge evaluation. Azure Blob Storage additionally helps in creating highly effective cloud-based apps and knowledge lakes for analytical wants. 

This text will clarify tips on how to create Azure Blob Storage utilizing Python. It can additionally elaborate on tips on how to learn the saved knowledge, replace the saved knowledge, and delete it. On this information, we’ll make the most of the Python Pillow library to create a picture blob. 

For this tutorial, the Python 3.5.x model would work. Additionally, guarantee that Azure Subscription is energetic with Azure Storage Account. You’ll be able to create an Azure Storage Account free of charge. 


1. Create Container in Azure Storage:

A single Azure Storage account can have many containers, and containers can in the end be used to retailer blobs. To create a container in Azure Storage account, click on Containers underneath Information Storage from the menu bar. Subsequent, click on on the + icon to create a container. Assign it a reputation of your alternative. 


2. Get the Connection String:

It’s essential to get the connection string for the Azure Storage Container to speak and work together with it. To get the connection string, click on on the Safety tab current on the navigation bar. Beneath the Safety tab, click on Entry Keys. Within the Entry Keys part, copy the connection string.


After copying the connection string worth, set it as a PATH, an setting variable, on the command immediate. To carry out this step, run the code given under:

setx AZURE_STORAGE_CONNECTION_STRING "Your_Connection_String" 


3. Set up the Required Packages:

Thirdly, set up the Azure Storage Blobs consumer library for Python utilizing the pip command on the command immediate. Be sure to put in pip earlier than executing this command. In any other case, the set up course of is not going to be full. 

pip set up azure-storage-blob


4. Create the Picture Useful resource:

On this step, create a pattern picture utilizing Python’s Pillow Library. Create a circle contained in the picture canvas and put it aside as a picture. For this step, execute the next code:

from PIL import Picture, ImageDraw

picture ='RGBA', (200, 200))

draw = ImageDraw.Draw(picture)

draw.ellipse((20, 20, 180, 180), fill = 'black', define ='black')

draw.level((100, 100), 'black')'check.png')


Earlier than executing this code, be certain to put in the Pillow library utilizing the command given under:

pip set up pillow


5. Create Blob in Azure Storage Account:

The subsequent step is to arrange a consumer to speak with the Azure Container. For the reason that Azure Storage Blob library allows customers to create three sorts of storage assets: the storage account, the container, and the blob, a consumer is required to work together with the assets. Step one is to get the connection string from the PATH. Then, use that connection string to arrange the Blob Service Shopper object. 

import os

connect_str = os.getenv('AZURE_STORAGE_CONNECTION_STRING')

Now, the following step is to create the Blob Service Shopper object as follows:

from import BlobServiceClient

blob_service_client = BlobServiceClient.from_connection_string(connect_str)


Now, go forward and set the trail for the native picture file which was created in Step 4.

local_file_name = "check.png"

local_path = "/content material"

upload_file_path = a part of(local_path, local_file_name)

After that, create a blob consumer. Right here, it’s possible to supply the identical identify for the blob because the native filename for comfort.

blob_client = blob_service_client.get_blob_client(container=container_name, blob=local_file_name)

Lastly, create the blob on the Azure Storage account. 

with open(upload_file_path, "rb") as knowledge:


Lastly, you’ve got created a blob in your container!


6. Learn Blobs from Azure Storage Account:

Azure Blob Service Object may also be used to learn the blobs from the container. For this step, execute the next code:

print("nListing blobs...")

# Learn all of the blobs within the container

blob_list = container_client.list_blobs()

for blob in blob_list:

    print("t" + blob.identify)



7. Replace the Blob on Azure Storage: 

Replace operations could be executed in the same method as elaborated above. As an example, you wish to replace the colour of the present picture and overwrite it on the blob. On this case, you’ll use the upload_blob() operate and go TRUE within the overwrite parameter. 

For instance:

with open(upload_file_path, "rb") as knowledge:

blob_client.upload_blob(knowledge, overwrite=True)

Therefore, the present picture blob can be overwritten with the brand new blob picture.

8. Delete the Blob from the Azure Storage Account:

It’s attainable to delete the present blobs from the container in your Azure Storage Account utilizing the Blob Service Object as proven under:


After executing the command, head over to Azure Portal to verify that the operation is profitable.


In conclusion, the Azure Storage account offers performance to carry out CRUD operations not solely by its portal or Powershell but additionally utilizing Python. This text has coated the fundamental create, learn, replace and delete operations on blob storage utilizing Azure Storage performance. We hope this information will help you in establishing your blob storage and performing CRUD operations utilizing Python efficiently.

Blissful coding and dont neglect to attempt one thing new day-after-day 🙂
