Introduction
This guide explains how to use GitHub Actions to build and deploy a Python project to Azure App Service.
Prerequisites
Before creating your GitHub Actions workflow, you will first need to complete the following setup steps:
-
Create an Azure App Service plan.
For example, you can use the Azure CLI to create a new App Service plan:
Shell az appservice plan create \ --resource-group MY_RESOURCE_GROUP \ --name MY_APP_SERVICE_PLAN \ --is-linux
In the command above, replace
MY_RESOURCE_GROUP
with your pre-existing Azure Resource Group, andMY_APP_SERVICE_PLAN
with a new name for the App Service plan.See the Azure documentation for more information on using the Azure CLI:
- For authentication, see "Sign in with Azure CLI."
- If you need to create a new resource group, see "az group."
-
Create a web app.
For example, you can use the Azure CLI to create an Azure App Service web app with a Python runtime:
Shell az webapp create \ --name MY_WEBAPP_NAME \ --plan MY_APP_SERVICE_PLAN \ --resource-group MY_RESOURCE_GROUP \ --runtime "python|3.8"
In the command above, replace the parameters with your own values, where
MY_WEBAPP_NAME
is a new name for the web app. -
Configure an Azure publish profile and create an
AZURE_WEBAPP_PUBLISH_PROFILE
secret.Generate your Azure deployment credentials using a publish profile. For more information, see "Generate deployment credentials" in the Azure documentation.
In your GitHub repository, create a secret named
AZURE_WEBAPP_PUBLISH_PROFILE
that contains the contents of the publish profile. For more information on creating secrets, see "Encrypted secrets." -
Add an app setting called
SCM_DO_BUILD_DURING_DEPLOYMENT
and set the value to1
.
Creating the workflow
Once you've completed the prerequisites, you can proceed with creating the workflow.
The following example workflow demonstrates how to build and deploy a Python project to Azure App Service when there is a push to the main
branch.
Ensure that you set AZURE_WEBAPP_NAME
in the workflow env
key to the name of the web app you created. If you use a version of Python other than 3.8
, change PYTHON_VERSION
to the version that you use.
If you configured a deployment environment, change the value of environment
to be the name of your environment. If you did not configure an environment, delete the environment
key.

# They are provided by a third-party and are governed by
# separate terms of service, privacy policy, and support
# documentation.

The following resources may also be useful:
- For the original starter workflow, see
azure-webapps-python.yml
in the GitHub Actionsstarter-workflows
repository. - The action used to deploy the web app is the official Azure
Azure/webapps-deploy
action. - For more examples of GitHub Action workflows that deploy to Azure, see the actions-workflow-samples repository.
