Azure WebApp - Unable to auto-detect the runtime stack of your app - azure

Question

I'm trying to create Web App which is just having a Static HTML. I'm following this link https://learn.microsoft.com/en-us/azure/app-service/app-service-web-get-started-html. But when I execute the following command
az webapp up --location westeurope --name .
Got the error - " Could not auto-detect the runtime stack of your app" .

Answer 1

I tried the following, but added the --html flag at the end of the az webapp up command to bypass auto detection:
mkdir quickstart
cd quickstart
git clone https://github.com/Azure-Samples/html-docs-hello-world.git
cd html-docs-hello-world
az webapp up --location westeurope --name azurewebapptest123 --html
That forces HTML. In the help for the command it implies auto-detection works for a bunch of language, but not for static HTML.

Answer 2

I just tried following the steps mentioned in the documentation. Works for me.
mkdir quickstart
cd quickstart
git clone https://github.com/Azure-Samples/html-docs-hello-world.git
cd html-docs-hello-world
az webapp up --location westeurope --name azurewebapptest123

Answer 3

I have tried the similar steps using the sample repo and was able to reproduce it.
Here is the version:
It's a known bug for Azure CLI 2.0.78 and team is working on it, Which you can track it here:
https://github.com/MicrosoftDocs/azure-docs/issues/43633
Work around of this issue is to use the older version of Azure CLi e.g. 2.0.75 * for deploying the solution.
Hope it helps.

Answer 4

Try to manually include a web.config file and/or select the stack on General Settings:
If you have no backend, the best option to host a static site is through Azure Storage:

Answer 5

I had the same problem. I solved it by using the flag --html to define explicitly the runtime according to the documentation of the runtime detection. https://github.com/Azure/app-service-linux-docs/blob/master/AzWebAppUP/runtime_detection.md
So, the solution is the following line of code:
az webapp up --location westeurope --name <name> --html
N.B: I used Azure cloud shell.

Answer 6

Make sure you're running the command "az webapp up --location westeurope --name" from your application root, ie inside 'html-docs-hello-world' folder.

Answer 7

at end of az webapp command you have give run time stack
if you are using an html page then --html you must give
Ex: az webapp up --location westeurope --name az204samplewebapphtml1 --html

Answer 8

To overcome this error you will need to:
cd {directory}
pip freeze > requirements.txt
The file does not need to have anything just needs to exist as azure looks for the files presence when running the deployment
