Flask-Azure-Storage 
A Flask extension that provides integration with Azure Storage
Table of Contents
Install
pip install Flask-Azure-Storage
Usage
Set the account credentials in your app.config:
AZURE_STORAGE_ACCOUNT_NAME = "your-account-name"
AZURE_STORAGE_ACCOUNT_KEY = "your-account-key"
Initialize the extension:
from flask import Flask
from flask.ext.azure_storage import FlaskAzureStorage
app = Flask(__name__)
azure_storage = FlaskAzureStorage(app)
Or, if you follow the Flask application factory pattern:
from flask import Flask
from flask.ext.azure_storage import FlaskAzureStorage
azure_storage = FlaskAzureStorage()
def create_app(config):
app = Flask(__name__)
app.config.from_object(config)
# initialize azure storage on the app within create_app()
azure_storage.init_app(app)
From the azure_storage object you can now access any of the following classes:
| Attribute | Class |
|---|---|
| azure_storage.account | azure.storage.cloudstorageaccount.CloudStorageAccount |
| azure_storage.block_blob_service | azure.storage.blob.blockblobservice.BlockBlobService |
| azure_storage.page_blob_service | azure.storage.blob.pageblobservice.PageBlobService |
| azure_storage.append_blob_service | azure.storage.blob.appendblobservice.AppendBlobService |
| azure_storage.queue_service | azure.storage.queue.queueservice.QueueService |
| azure_storage.table_service | azure.storage.table.tableservice.TableService |
| azure_storage.file_service | azure.storage.file.fileservice.FileService |
Examples
Create container
azure_storage.block_blob_service.create_container('container-name')
Delete container
azure_storage.block_blob_service.delete_container('container-name')
Upload a file
from azure.storage.blob import ContentSettings
azure_storage.block_blob_service.create_blob_from_path(container_name='container-name', blob_name='uploaded-file-name', file_path='/path/to/your/file.png', content_settings=ContentSettings(content_type='image'))
Delete a file
azure_storage.block_blob_service.delete_blob('container-name', 'uploaded-file-name')
Check if file exists
azure_storage.block_blob_service.exists('container-name', 'uploaded-file-name')
More examples
There are plenty more things you can do. For more examples, check out the Azure Storage SDK for Python samples
Seamless integration with Flask's static assets ('static' folder)
Automatically upload the static assets associated with a Flask application to Azure Storage.
You don't need to manually change your url_for calls, Flask-Azure-Storage will automatically target Azure where you call url_for('static', ...) in your Jinja themes.
This feature is based on flask-s3, intending to implement similar functionality based on the Azure Storage service. It is still under development so please report any issues.
To upload all your static files first set the following parameters in the app.config:
AZURE_STORAGE_ACCOUNT_NAME = "your-account-name"
AZURE_STORAGE_ACCOUNT_KEY = "your-account-key"
AZURE_STORAGE_CONTAINER_NAME = "your-container-name" # make sure the container is created. Refer to the previous examples or to the Azure admin panel
AZURE_STORAGE_DOMAIN = 'your-account-base-domain'
Then you can call the method create_all from the python interpreter:
>>> from flask import current_app
>>> from flask.ext.azure_storage import create_all
>>> create_all(current_app)
Or, a better choice (if you use something like FLask-Script):
app = create_app(os.getenv('FLASK_CONFIG') or 'default')
manager = Manager(app)
@manager.command
def deploy_azure():
from flask.ext.azure_storage import create_all
create_all(app)
So now it is possible to simply call python manage.py deploy_azure to upload your assets.
