Az_AppServices

Deploying a python-flask application in Azure App Service using CLI from Windows

Pre-requisites:

• First of all, we need a sample python project which can be deployed to Azure App Services
• Request you to follow the below mentioned Repository as it has been updated
• Follow the latest and updated py-flask App

Configurations:

1. Create a new directory from powershell C:\tmp\azureappdemo and cd into it

   mkdir C:\tmp\azureappdemo
   cd C:\tmp\azureappdemo
   

2. Now, clone the code locally into your system

   git clone https://github.com/Prozects/msdocs-python-flask-webapp-quickstart.git
   

   cd msdocs-python-flask-webapp-quickstart
   

3. Check if the python already exists in your system, If not found in your local m/c, kindly install it from an Elevated terminal using chocolatey

   python --version
   

4. Next, after python installation & confirmation, create a virtual environment which is specific to the python application

   py -m venv .venv
   

5. Activate the virtual environment

   .\.venv\scripts\Activate.ps1
   

6. Install Flask

   pip install -r requirements.txt
   

Login into Azure CLI:

az login

• Unsure about further commands or lost with commandline

  az webapp --help
  

• Check for all the installed runtimes (what all technologies that are supported)

  az webapp list-runtimes
  

• We got the following o/p

• Let’s bring up the Azure App Service with some appservice plan

  az webapp up --runtime PYTHON:3.9 --sku F1 --logs
  

’–sku’ F1=Free Plan, B1=Basic Plan

’–logs’ where we can see the logs of this application

• If the deployment is successful, we get the following output in the terminal

• Navigate to the ‘URL’ highlighted in the above image
