Azure Function Runtime Version

01 Sign in to the Azure Management Console.

02 Navigate to All resources blade at https://portal.azure.com/#view/HubsExtension/BrowseAll to access all your Microsoft Azure cloud resources.

03 Choose the Azure subscription that you want to access from the Subscription filter box and choose Apply.

04 From the Type filter box, select Function App and choose Apply to list only the Microsoft Azure Function Apps available in the selected subscription.

05 Click on the name (link) of the Azure Function App that you want to examine.

06 In the navigation panel, under Settings, select Configuration to access the application settings configured for the selected Function App.

07 Select the Application settings tab and check the following application settings: FUNCTIONS_WORKER_RUNTIME for the runtime language and FUNCTIONS_EXTENSION_VERSION for runtime version installed. Compare the runtime language and version with the updated list of Function App runtimes supported by Microsoft Azure. If the FUNCTIONS_EXTENSION_VERSION is not configured to use the latest version supported by Microsoft Azure, the selected Azure Function App is using an old and deprecated runtime environment.

08 Repeat steps no. 5 – 7 for each Azure Function App deployed in the selected Azure subscription.

09 Repeat steps no. 3 – 8 for each subscription created in your Microsoft Azure cloud account.

01 Run functionapp list command (Windows/macOS/Linux) using custom query filters to list the name and the associated resource group for each Azure Function App available in the current subscription:

az functionapp list 
  --output table 
  --query '[*].{name:name, resourceGroup:resourceGroup}'

02 The command output should return the requested Function App names:

Name                      ResourceGroup
----------------------    ------------------------------
cc-main-function-app      cloud-shell-storage-westeurope
cc-project5-function-app  cloud-shell-storage-westeurope

03 Run functionapp config appsettings list command (Windows/macOS/Linux) using the name of the Azure Function App that you want to examine and its associated resource group as the identifier parameters to list the application settings configured for the selected Function App:

az functionapp config appsettings list 
  --name cc-main-function-app 
  --resource-group cloud-shell-storage-westeurope 
  --query '[*].[name,value]'

04 The command output should return the requested application configuration information:

[
	[
		"FUNCTIONS_WORKER_RUNTIME",
		"python"
	],
	[
		"FUNCTIONS_EXTENSION_VERSION",
		"~3"
	],
	[
		"ENABLE_ORYX_BUILD",
		"1"
	],
	[
		"SCM_DO_BUILD_DURING_DEPLOYMENT",
		"1"
	],
	[
		"WEBSITE_CONTENTSHARE",
		"cc-main-function-app8adc"
	]
]

az functionapp config appsettings set 
  --name cc-main-function-app 
  --resource-group cloud-shell-storage-westeurope 
  --settings FUNCTIONS_EXTENSION_VERSION=~4

02 The command output should return the new application settings configured for the selected Azure Function App:

[
	{
		"name": "FUNCTIONS_WORKER_RUNTIME",
		"slotSetting": false,

	},
	{
		"name": "FUNCTIONS_EXTENSION_VERSION",
