Use an Azure Function through Kong Gateway

This is a Konnect tutorial and requires a Konnect personal access token.

1. Create a new personal access token by opening the Konnect PAT page and selecting Generate Token.

2. Export your token to an environment variable:

    export KONNECT_TOKEN='YOUR_KONNECT_PAT'
   

3. Run the quickstart script to automatically provision a Control Plane and Data Plane, and configure your environment:

    curl -Ls https://get.konghq.com/quickstart | bash -s -- -k $KONNECT_TOKEN --deck-output
   

   This sets up a Konnect Control Plane named quickstart, provisions a local Data Plane, and prints out the following environment variable exports:

    export DECK_KONNECT_TOKEN=$KONNECT_TOKEN
    export DECK_KONNECT_CONTROL_PLANE_NAME=quickstart
    export KONNECT_CONTROL_PLANE_URL=https://us.api.konghq.com
    export KONNECT_PROXY_URL='http://localhost:8000'
   

   Copy and paste these into your terminal to configure your session.

This tutorial requires Kong Gateway Enterprise. If you don’t have Kong Gateway set up yet, you can use the quickstart script with an enterprise license to get an instance of Kong Gateway running almost instantly.

1. Export your license to an environment variable:

    export KONG_LICENSE_DATA='LICENSE-CONTENTS-GO-HERE'
   

2. Run the quickstart script:

    curl -Ls https://get.konghq.com/quickstart | bash -s -- -e KONG_LICENSE_DATA 
   

   Once Kong Gateway is ready, you will see the following message:

    Kong Gateway Ready
   

decK is a CLI tool for managing Kong Gateway declaratively with state files. To complete this tutorial you will first need to install decK.

For this tutorial, you’ll need Kong Gateway entities, like Gateway Services and Routes, pre-configured. These entities are essential for Kong Gateway to function but installing them isn’t the focus of this guide. Follow these steps to pre-configure them:

1. Run the following command:

   echo '
   _format_version: "3.0"
   services:
     - name: example-service
       url: http://httpbin.konghq.com/anything
   routes:
     - name: example-route
       paths:
       - "/anything"
       service:
         name: example-service
   ' | deck gateway apply -
   

To learn more about entities, you can read our entities documentation.

This tutorial requires an Azure Function. In this example, we’ll use the quickstart function provided by Azure.

If you don’t have an existing Azure Function, you can create one by following the steps in Create your first function.

Once your function is created, save the following values to your environment:

• The Function App name. It’s generated automatically when deploying the quickstart function.
• The function name, httpget in this example.
• The API key to use to access the function. You can find it in your Function App details in the Azure portal, under Functions > App keys.

export DECK_APP_NAME='YOUR FUNCTION APP NAME'
export DECK_FUNCTION_NAME=httpget
export DECK_FUNCTION_APP_KEY='YOUR FUNCTION APP API KEY'
