Create Azure Function In Visual Studio Code In Python
Step 1: Download and install Visual Studio Code from the official website.
Step 2: Install required extensions
- Go to extensions section and search for ‘Azure Functions’ and click on install, also install python extension.
Step 3: Install Azure Function core tools
From this Link:
https://learn.microsoft.com/en-us/azure/azure-functions/functions-run-local?tabs=windows%2Cisolated-process%2Cnode-v4%2Cpython-v2%2Chttp-trigger%2Ccontainer-apps&pivots=programming-language-python
- By this tool you can test or deploy your azure function on your local machine.
- After downloading install that exe file.
Step 4: Sign In To Azure
After installing Azure Functions extension you will see “A” symbol in left pad click on that.
- Sign in to Azure, Here we will click on that, then you will be redirected to website to login into microsoft account once you login to your account will get connected to vs code.
Step 5: Create Function
- After logging in to your account you can see the interface as in the image. Right click on ‘Function App‘ and click on Create function App in Azure.
Step 6: Select Template
Here there comes lots of options for template like
- Blob trigger: In this scenario, the event trigger will execute the script when an event results in the manipulation of Azure Blob Storage, e.g., when a new blob is created, edited or deleted It actually enables you to create functions that waits for such events to happen before any action, such as performing a completion of the operation in your storage account.
- Cosmos DB trigger: With Cosmos DB trigger, you can construct Azure functions that are responsive to any modifications made to your collection in Cosmos DB. Such activities entail creating of documents, as well as modifying or even removing them.
- Event Hub trigger: This trigger allows you to pipe events coming from an Azure Event Hub using the proven Data Processing Technology that makes your streaming data accessible and ready to be used for Machine Learning and data analytics. Using Azure Functions that react to data streaming in the Event Hub you have created can help to process real-time data as well as reactive scenarios involving a event related instance.
- Queue trigger: Azure Storage Queue is a message queue that you can use as the stimulus to create an Azure Function to process messages from. It also assists in providing huge app uptime by running tasks asynchronously or across different instances.
- Time trigger: With Time-based trigger, one can program the Azure Functions to run at specific time-based events. It is very helpful for the output which should be performed repeatedly. Such tasks or actions should be performed in accordance to a given schedule.
- you can select the desired trigger type when creating a new function in the Azure Portal or Visual Studio Code with the Azure Functions extension. Now I am selecting HTTP trigger for just showing how to create.
Step 7: Select Authorization Level Controls
- Function: Such an address refers to the authentication level as it is default, so anybody can use the function right after the deployment without any kind of specific identification or authorization. Meaning, the page can be run and executed by anybody who has the function’s URL address.
- Anonymous: Like this, the Anonymous Authorization level, which is the ability of anyone to invoke the function without any specific authentication or authorization. In this format you make the function you are interested in user friendly.
- Admin: Admins grant access level requires caller to have an Azure AD token parameters with administrator role. It is more secure implementation because it secures that only those who have admin rights or authorized users can invoke the function.
You can set the Authorization level while configuring the function’s hosting settings in the local.settings.json file during development or in the Azure Portal when deploying your function to the Azure platform.
Step 8: Select Runtime Stack
- Select the latest version of python make sure that the extension is installed in vs code and also install python in your pc.
- Finally after all these steps you will see the notification that the Azure Function App is created!
- You can also verify that the function is created or not by checking in Microsoft Azure website itself.
- Navigate to Microsoft Azure and search for functions click on that you will be listed all the existing functions created.
Next After creating an Azure Function
- Create a new python script in that function folder and give the name for it like myfunction.py
- then add the code you want like flask based HTTP trigger.
- After that try running it locally by typing “func start” in terminal and it will be accessible at http://localhost:7071/<function-name>
- Deploy function to Azure: right click on Azure Functions > Deploy to Function App…
- After Deployment you can access your function using the provided Azure URL.
How To Create Azure Function In Visual Studio Code Using Python ?
Let us see how amazing Python and Visual Studio code are when combined with Azure Function! Azure Functions lets you create not only absurdly, scalable, and affordable applications but also apps of different kinds like CMS, Job Section, etc. And guess what? You can enjoy this without having to worry about servers in your management area.
Starting with, we will set up your computer for lively coding and begin to create miraculous functions. Next, we’ll download and install our functions from the internet that we can do right on our computers. In addition, we will guide on how this can be made even simpler by allowing them to bind with other Azure Services. That means you are covered in case your apps go big, but you do not pay a fortune at the same time.
Coding on Azure Functions with Python with Visual Studio Code is going to be a great learning experience, so let’s do it together! With this guide, you’ll become a professional in working with Azure functions at the end of this course. Then there comes an interesting fact that what inventions would be unanimous to you? Therefore, start off with upgrading your coding knowledge and let us reach above-average development.
