Check Function App Stack

This script is for retrieving all of the function app stacks in your Azure Subscriptions you have access to.

#!/bin/bash

# Log in to Azure (if not already logged in)
# az login

# Get the list of subscriptions
subscriptions=$(az account list --query "[].id" -o tsv)

# Print the header of the CSV.
echo "subscroptionId, name, resourceGroup, stack"
# Iterate through each subscription
while IFS= read -r subscriptionId; do
    # Set the current subscription
    az account set --subscription "$subscriptionId"

    # List all Function Apps in the current subscription
    function_apps=$(az functionapp list --query "[].{name:name, resourceGroup:resourceGroup}" -o tsv)

    # Iterate through each Function App
    while IFS=$'\t' read -r name resourceGroup; do
        # Get the configuration of the Function App
        config=$(az functionapp config show --name "$name" --resource-group "$resourceGroup" -o json)

        # Extract the stack and stack version
        linuxFxVersion=$(echo "$config" | grep -oP '(?<="linuxFxVersion": ")[^"]*')
        windowsFxVersion=$(echo "$config" | grep -oP '(?<="windowsFxVersion": ")[^"]*')

        # Determine the stack and version
        if [ -n "$linuxFxVersion" ]; then
            stack="$linuxFxVersion"
        elif [ -n "$windowsFxVersion" ]; then
            stack="$windowsFxVersion"
        else
            stack="Unknown"
        fi

        # Print the Function App details
        echo $subscriptionId, $name, $resourceGroup, $stack
    done <<< "$function_apps"
