Terraform (and AzureRM Provider) Version

Terraform v0.12.18
AzureRM v1.40.0

Affected Resource(s)

azurerm_app_service_plan
azurerm_function_app

Terraform Configuration Files

Here is the module invocation



module "function_app" {

source = "./modules/functionapp_v1"

name = "a8reeenginetest"

resource_group_name = module.air_resourcegroup.name

app_service_plan_id = azurerm_app_service_plan.serviceplan.id

location = var.location

environment = var.environment

function_version = "~2"

#release = "release 2019-12-10:001"

primary_connection_string = azurerm_storage_account.functionsta.primary_connection_string



app_settings = {

FUNCTIONS_WORKER_RUNTIME = "python"

APPINSIGHTS_INSTRUMENTATIONKEY = module.air_appinsights.instrumentation_key

WEBSITE_NODE_DEFAULT_VERSION = "10.14.1"

}

}



and the function app





#version = 1.0 # Release Date: 26-11-2019

resource "azurerm_function_app" "main" {

name = var.name

location = var.location

resource_group_name = var.resource_group_name

app_service_plan_id = var.app_service_plan_id

storage_connection_string = var.primary_connection_string

https_only = true

version = var.function_version

client_affinity_enabled = false



tags = "${merge(var.tags, map("environment", var.environment), map("release", var.release))}"







site_config {

always_on = true

}



identity {

type = "SystemAssigned"

}



app_settings = var.app_settings



/*lifecycle {

ignore_changes = ["app_settings"]

}*/

}



It is deploying to the following app service plan



resource "azurerm_app_service_plan" "serviceplan" {

name = "a8reeenginetest"

location = var.location

resource_group_name = module.air_resourcegroup.name

kind = "Linux"

reserved = true

sku {

tier = "Dynamic"

size = "P1V2"

}

Expected Behavior

An operational Function App should be deployed

Actual Behavior

The Function App is not correctly deployed.

When my code is deployed, there is an error when going into the Function App settings in the portal

Error:

Experiencing the same issue. @a8ree did you find the root cause by any chance or a workaround?

[a8ree]

@umsheikh83 no, I've got a case open with Hashicorp which has been passed to engineering. It seems to be an issue with linux plans. Setting to 'elastic' or 'windows' will work but there is some sort of issue when deploying on linux - which doesn't happen when you using the Azure Portal to deploy

[katbyte]

@a8ree - we have fixed a bug wth libnux deployments in #7140 and updated the docs in #7146 - could you take a look and see if your still experiancing this issue?

[pc-tradelab]

Hello any update on that issue ? I still have a problem depoying a very simple python function app. #7146 is useful , however a working example with python code would be great ( in particular the example folder of this repo does not containe any example of how to deploy an app function) .

[borkod]

Hello. I've created an example used to demonstrate how to provision a python functions app. It includes sample python code. I was able to deploy it using VS code. README file has links to references on how to deploy code to function app using a number of methods. Hope this helps! Code is part of PR: #8724

[jbinko]

Not entirely sure - Can this be closed? as PR: #8724 seems to be merged into master. https://github.com/terraform-providers/terraform-provider-azurerm/tree/master/examples/app-service/function-python/SampleApp

[favoretti]

Since this issue seems to have been addressed in the latest versions of the provider (or a valid workaround was provided) - I'm going to close it. Please open a new updated bug report if this is still relevant. Thank you.
