I have a Python Azure function which executes locally. It is deployed to Azure and I selected the 'free app plan'. The Python has dependencies on various modules, such as requests. The modules are not loaded into the app like they are locally on my machine. The function fails when triggered.
I have tried installing the dependencies using Kudu console from my site, this hangs with message cleaning up >> every time.
I have tried installing the dependencies using SSH terminal from my site, the installations succeed but i cannot see the modules when python pip list in kudo and the app still fails. I cannot navigate the directories ls does nothing.
I tried to install extensions using the portal but this option is greyed out in development-tools.
You can find a requirements.txt in your local function folder.
If you want function on azure to install the 'requests', your requirements.txt should be like this:(Azure will install the extension based on this file)
azure-functions
requests
And all these packages will be packaged into a new package on Azure, so you can not display which packages using pip list. Also, please keep in mind that Linux's Kudu feature is limited and you cannot install packages through it.
Problem seems comes from VS Code, you can use command to deploy your function app.
For example, my functionapp on Azure named 423PythonBowman2, So this is my command:
func azure functionapp publish 423PythonBowman --build remote
I quoted requests in the code, and with cmd deploy my function can works fine on portal with no errors.
Have a look of the offcial doc:
https://learn.microsoft.com/en-us/azure/azure-functions/functions-run-local?tabs=macos%2Ccsharp%2Cbash#publish

I have created a python project in VS Code and deployed it on Azure Function with all the required file like requirements.txt.
Code is running successfully on my local machine but giving error when I am running it on Azure Function as "No module named 'requests'".
My requirements.txt file consist of following elements:
azure-functions
requests
PyJWT
cryptography
So Is there any way to manually install this package on Azure Functions Linux VM. I am using consumption plan of Azure functions
Code is running successfully on my local machine but giving error when I am running it on Azure Function as "No module named 'requests'".
Your function can run successfully locally, indicating that requests has been installed.
You can try to use this command to generate your requirements.txt in case the requirements.txt created by yourself is wrong:
pip freeze > requirements.txt
Then you can try to redeploy, if it is not successful, you can try to deploy your function using this command:
func azure functionapp publish <function app name> --build remote
<function app name> is the name of your Azure Function App in your Azure Portal.
In my Az Function app, I have some ubuntu packages like Azure CLI and Kubectl that I need to install on the AZ Host whenever it starts a new container. I have already tried Start-up Commands and also going into the Bash. The former doesnt work and the latter tells me permission is denied and resource is locked. Is there any way to install these packages on function start-up in Azure Functions?
If you try to install the package via bash, it is impossible and will not be dealt with at all. The reason is because when you use python to write functions and deploy them to linux os on azure, in fact it installs various packages according to requirements.txt, and finally merges these packages into a whole. When you run the function on azure, you are based on this whole package. Therefore, if it is incorrect to try to install the package after deployment, you should specify the package to be installed in requirements.txt before deployment and then deploy to azure.
I am trying to deploy a Flask app to an Azure Web App (Linux, python3.7 runtime) using FTP.
I copied the "application.py" over and a "requirements.txt", but I can see in the logs that nothing is being installed.
The Web App is using an 'antenv' virtual environment but it won't install anything. How do I add libraries to this 'antenv' virtual environment?
Yes, I see that you have resolved the issue. You must use Git to deploy Python apps to App Service on Linux so that your dependencies in requirements.txt are installed (root folder).
To install Django and any other dependencies, you must provide a requirements.txt file and deploy to App Service using Git.
The antenv folder is where App Service creates a virtual environment with your dependencies. If you expand this node, you can verify that the packages you named in requirements.txt are installed in antenv/lib/python3.7/site-packages. Refer this document for more details.
Additionally, Although the container can run Django and Flask apps automatically, provided the app matches an expected structure, you can also provide a custom startup command file through which you have full control over the Gunicorn command line. A custom startup command is typically required for Flask apps, but not Django apps.
Turns out I had to run these commands and do a git push while my local venv was activated. At that point I saw azure start downloading all the libraries in my requirements.txt
I've developed and tested a dash app. It works as expected. Next step is to deploy the app to AWS Elastic Beanstalk using a preconfigured Docker container.
I am currently trying to set up a local docker environment for testing as described here
Running the command (via PowerShell):
docker build -t dash-app -f Dockerfile.
successfully downloads the preconfigured image, then proceeds to install python modules as specified in requirements.txt, until it gets to the cryptography module, where it throws a runtime error saying it requires setuptools version 18.5 or newer.
My Dockerfile has this line in it:
FROM amazon/aws-eb-python:3.4.2-onbuild-3.5.1
I've tried adding a line to the dockerfile to force upgrade pip and setuptools within the container as suggested here and here, but nothing seems to work.
I am deploying a WebJob inside Azure Web App that uses Google Maps API and Azure SQL Storage.
I am following the typical approach where I make a WebJob directory and copy my 'site-packages' folder inside the root folder of the WebJob. Then I also add my code folder inside 'site-packages' and make a run.py file inside the root that looks like this:
import sys, os
sys.path.append(os.path.join(os.getcwd(), "site-packages"))
import aero2.AzureRoutine as aero2
aero2.run()
Now the code runs correctly in Azure. But I am seeing warnings after a few commands which slow down my code.
I have tried copying 'pyopenSSL' and 'requests' module into my site-packages folder, but the error persists.
However, the code runs perfectly on my local machine.
How can I find this 'pyopenSSL' or 'requests' that is compatible with the python running on Azure?
Or
How can I modify my code so that it pip installs the relevant packages for the python running on Azure?
Or more importantly,
How can I resolve this error?
#Saad,
If your webjob worked fine on Azure Web App, but you got inscuritywaring, I suggest you can try to disable the warning information via this configuration(https://urllib3.readthedocs.org/en/latest/security.html#disabling-warnings ).
Meanwhile,requests lib has some different with the high version, I recommend you refer to this document:
http://fossies.org/diffs/requests/2.5.3_vs_2.6.0/requests/packages/urllib3/util/ssl_.py-diff.html
And Azure web app used the Python 2.7.8 version which is lower than 2.7.9. So you can download the requests lib as version 2.5.3
According the doc referred in the warning message https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning:
Certain Python platforms (specifically, versions of Python earlier than 2.7.9) have restrictions in their ssl module that limit the configuration that urllib3 can apply. In particular, this can cause HTTPS requests that would succeed on more featureful platforms to fail, and can cause certain security features to be unavailable.
So the easiest way fix this warning, is to upgrade the python version of the Azure Web Apps. Login the Azure manager portal, change the python version to 3.4 in Application settings column:
As I test in webjob task to use requests module to request a "https://" url, and since upgrade python version to 3.4, there are no more warnings.
I followed this article and kind of 'pip installed' the pymongo library for my script. Not sure if it works for you but here are the steps:
Make sure you include the library name and version in the requirements.txt
Deploy the web app using Git. The directory should include at least
requirements.txt (only to install whatever is in requirements.txt in the virtual environment, which is shared with Web App in D:\home\site\wwwroot\env\Lib\site-packages)
add this block of code to the Python code you want to use in the WebJob zip file.
import sys
sitepackage = "D:\home\site\wwwroot\env\Lib\site-packages"
sys.path.append(sitepackage)
