Deploy your Python code on Azure Functions
0 likes75 views
This document discusses Python Azure Functions. Azure Functions is an event-driven serverless compute platform on Microsoft Azure. It allows building web APIs, processing data streams, and more using event triggers and bindings without managing infrastructure. The document covers setting up the Azure Functions Core tools and Azure CLI to create, develop and deploy Python functions to Azure from the command line. It also provides an overview of the deployment process, including creating resource groups and storage accounts, and publishing functions to Azure.

Install the Microsoft package repository GPG key
curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dea
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg
Set up the APT source
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/
Install the Core Tools package ( func binary)

- 3. I have no idea what I am talking about
- 4. Azure Functions Event-driven serverless compute platform On-demand service Provides a continually-updated infrastructure You can build web APIs, respond to database changes, process IoT streams, manage message queues, and more. Only worry about our app and not infrastructure Automatically scales
- 5. Supported Languages Python C# Go Java JavaScript / TypeScript PowerShell Rust Any other Language (Custom Image + PowerShell)
- 6. Deployment Approaches 1. Commandline 2. VS Code (with an of cial azure plugin) I will be taking the command line approach on my Debian machine as it's easier for me. So the rest of the talk will use this method. If you are someone who likes to use GUI tools, you should probably opt for VS Code approach: https://docs.microsoft.com/en-us/azure/azure- functions/create- rst-function-vs-code-python
