How to view contents of function app zip post deployment?

Ashwin Venkatesha 230

I have published a function app using the below command

func azure functionapp publish timedapicall  --build remote --python

I see an entry in storage account's scm-releases container.

However, if i try to download and open the zip file, it keeps throwing an error that it is an unsupported format.

An attempt to access via scm.azurewebsites.net doesnt show debug console dropdown either. Deployments link doesnt open anything either.

Hi Ashwin Venkatesha,

Thanks for reaching out to Microsoft Q&A.

To view the contents of a function app zip file after deployment, you can try using one of the below options, esp., Kudu service or Azure CLI which can be more handy.

Kudu Service:

Access Kudu by navigating to https://<app_name>.scm.azurewebsites.net.

Use the Debug Console to navigate to the D:\home\data\SitePackages directory.

Find the zip file, which contains the timestamp and the packagename.txt file indicating the currently deployed package.

https://learn.microsoft.com/en-us/azure/azure-functions/deployment-zip-push

Azure CLI:

Use the az functionapp deployment source config-zip command to deploy and manage your function app zip files.

https://learn.microsoft.com/en-us/azure/azure-functions/deployment-zip-push

REST APIs:

Deploy the zip file to your app by sending a POST request to https://<app_name>.scm.azurewebsites.net/api/zipdeploy.

https://learn.microsoft.com/en-us/azure/azure-functions/deployment-zip-push

Using FTP

Get FTP Credentials:

go to your Function App & in the left-hand menu, select Deployment Center.

Under the FTP/Credentials tab, note down the FTP hostname, username, and password.

Use an FTP client (FileZilla) to connect to your Function App using the FTP credentials.

In the FTP client, navigate to the /site/wwwroot directory.

Now download the files to your local machine or view them directly within the FTP client.

Hi @Vinodh247
Thanks for the reply. But the question is different, I did download the zip file but cannot view the contents of it.

Please check the screenshots as well. Could you suggest what may be wrong here?

Here is my usecase for this, I have a solution deployed on sentinel that uses Website_run_from_package that points to a url.

Im having difficulty in adding packages to .python_packages due to versioning. So manually adding packages to zip file doesnt work, instead publishing the same from local vscode does work.
Since it works, I want to access the zip file post deployment, so that I can copy the packages I need and manually update my solution zip. I cannot expect end users to use vscode to deploy solution.

Ashwin Venkatesha: you mean, once you have downloaded the zip and extracted it you are unable to add or update the necessary Python packages in the .pythonpackages directory within the extracted folder?

Yes, I want to update the packages in this manner but am not able to open the zip itself.

weird! did you try using tools like 7zip to extract and then recompress it again?

@Ashwin Venkatesha have you looked into local package build?

I tried 7zip and other tools, none of them work. I think this is a bug.
Secondly, here is what I tried, after I set up a virtualenv and ran python install -r requirements.txt, it did set up all packages locally in vscode.
I selectively copied the packages that resides on my remote branch.
Then restarted the function app and since I had website_run_from_package set to that zip file, my assumption was new packages would have fixed the error I was seeing.
But that did not. It was the same error.

@Ashwin Venkatesha what error are you seeing? Are you explored using a container app instead to gain more granular control of your local packages?

The function fails because some package did not load as expected. This is if I manually add the packages.

In case, I publish the solution using func publish build remote
then it works as expected.
How to explore using container app?

My requirement is this, access all the python packages that have been deployed for a function app.

How to explore using container app?

See Create your first containerized Azure Functions on Azure Arc | Microsoft Learn for the quick start guide.

In case, I publish the solution using func publish build remote then it works as expected.

I'm confused because I thought the dependencies weren't being restored? If you're adding packages after the fact, is it possible for you have those packages before-hand?

This is still an annoying issue
