Deploy flow using Azure App Service

This example demos how to deploy a flow using Azure App Service.

Azure App Service is an HTTP-based service for hosting web applications, REST APIs, and mobile back ends. The scripts (deploy.sh for bash and deploy.ps1 for powershell) under this folder are here to help deploy the docker image to Azure App Service.

We will use web-classification as example in this tutorial.

Build a flow as docker format app

Note that all dependent connections must be created before building as docker.

# create connection if not created before
pf connection create --file ../../../connections/azure_openai.yml --set api_key=<your_api_key> api_base=<your_api_base> --name open_ai_connection

Use the command below to build a flow as docker format app:

pf flow build --source ../../../flows/standard/web-classification --output build --format docker

Deploy with Azure App Service

The two scripts will do the following things:

  1. Create a resource group if not exists.
  2. Build and push the image to docker registry.
  3. Create an app service plan with the give sku.
  4. Create an app with specified name, set the deployment container image to the pushed docker image.
  5. Set up the environment variables for the app.

Example command to use bash script:

bash deploy.sh --path build -i <image_tag> --name my_app_23d8m -r <docker registery> -g <resource_group>

Example command to use powershell script:

.\deploy.ps1 -i <image_tag> --Name my_app_23d8m -r <docker registery> -g <resource_group>

Note that the name will produce a unique FQDN as AppName.azurewebsites.net.

See the full parameters by bash deploy.sh -h or .\deploy.ps1 -h.

View and test the web app

The web app can be found via azure portal

After the app created, you will need to go to https://portal.azure.com/ find the app and set up the environment variables at (Settings>Configuration) or (Settings>Environment variables), then restart the app.

Tips:

  • Reach deployment logs at (Deployment>Deployment Central) and app logs at (Monitoring>Log stream).
  • Reach advanced deployment tools at https://$name.scm.azurewebsites.net/.
