Webapp won't find github-hosted resources

Question

Webapp won't find github-hosted resources

Kevin GUIMARD 65

I created a webapp based on a python project whose code is to be retrieved from an external git provider. This project contains a file named main.py.

Now, if I use "python main.py" as the startup command, I get the following error in the log stream:
python: can't open file 'main.py'

I don't know what happens... Maybe Azure didn't manage to retrieve the files from git? The problem is that I don't see this step in the logs. I tried to use $APP_PATH, but it points to the same directory. azure By the way, I'm wondering why Azure runs a container after trying to execute the command. I would expect the command to be ran within the container. Could someone explain that to me?

Hi @Kevin GUIMARD ,
Welcome to MS Q&A platform.
Your Azure Web App appears to be unable to find main.py, which can signify problems with deployment, file paths or the container.

You can navigate to the Azure Portal > Your Web App > Deployment Center.

You can review the logs from deployment in order to confirm if files were fetched properly.

If there are no deployments available, please perform a manual sync:

Open Deployment Center, and Sync.

You can also browse the logs searching for possible errors.

Now, using Kudu console or SSH, let’s check if main.py exists:

Launch Kudu.

Select Debug Console > Bash.

ls -l /home/site/wwwroot/

If main.py is not listed, then the deployment failed to deliver your files.

Azure is set up to execute commands in /home/site/wwwroot/ by default. If main.py is located elsewhere, modify the Startup Command.

In Azure Portal, go to App Service > Configuration > General Settings.

In Startup Command,

python /home/site/wwwroot/main.py

Then save your changes and restart the Web App.

Your logs indicate that a container is active (docker run ...). If your Web App is Set to Container Mode by mistake, switch it to Code Mode.

Go to Azure Portal -> App Service -> Configuration -> General Settings.

Now Check the Stack Settings. If “Docker” is selected, adjust it accordingly to Python.

In the case where Git deployment is unsuccessful, Kudu can be used for manual Uploading the main.py:

Open Kudu Debug Console.

Drag & Drop main.py into /home/site/wwwroot/.

Restart the Web App.

You can now Start the App After Applying the Fixes.

After applying the fixes, restart your Web App

Open Azure Portal → App Service → Log Stream

Check for errors related to startup failures.

As I said, I see nowhere in the logs where the files are retrieved from git. I just don't even know whether it happens.

Besides, how do you run Kudu? I can't see it in the available commands. I haven't found a way to create a console pointing to my webapp.

After investigating the logs, the problem happens (as I expected) during the "git clone". I specified a git HTTPS URL as a git external provider. For some reason, my full e-mail seems to be included in the connection URL, which leads git to fail:

Error occurred, type: error, text: Repository url 'https://kevguima**@my-e-mail.net**:******@my-repo.git' is invalid.

But just with the username, it works (I tested it in local):

git clone https://kevguima:******@my-repo.git

How can I prevent this behaviour?

Hi @Kevin GUIMARD

python: can't open file 'main.py'

By default files/folders will be deployed to site/wwwroot directory.

python main.py , expects the main.py to be in the site/wwwroot folder.

Make sure the files are in the application root directory using the new ui - https://AppName.scm.azurewebsites.net/newui/fileManager.

enter image description here

You can open the KUDU console using this URL (https://AppName.scm.azurewebsites.net/).

enter image description here

I'm wondering why Azure runs a container after trying to execute the command

Azure App service deployed in Linux by default runs inside the containers. You can check the Log Stream in the KUDU Console.

Unchecking "Deployment slot setting" in environment variable solved the issue , allowing Oryx to handle the installation of dependencies automatically.

We found the solution: we had to uncheck "Deployment slot setting" in our environment variable so that Oryx could manage itself the installation of python libraries:
