Why is my triggers not showing in my azure function after a successful deployment?

Question

Why is my triggers not showing in my azure function after a successful deployment?

Ivan Louw 20

Hi, I am deploying a first time docker image to azure.

From what I can see the deployment was successful as per logs below:

Here is my docker file, but when I run the image locally the the function work and return the correct result.

# Base image with Python 3.9
FROM mcr.microsoft.com/azure-functions/python:4-python3.10

# Install git to clone the Bitbucket repository
RUN apt-get update \ 
    && apt-get install -y \
    build-essential \
    cmake \
    git \
    unixodbc-dev \
    && rm -rf /var/lib/apt/lists/*

#Copy secrets file

RUN mkdir /etc/secrets/
ENV FUNCTIONS_SECRETS_PATH=/etc/secrets
ENV AzureWebJobsSecretStorageType=Files
ADD host_secrets.json /etc/secrets/host.json

# Copy application code (optional, if you want to add any additional files or scripts)
COPY . /home/site/wwwroot

# Install dependencies from requirements.txt
COPY requirements.txt /
RUN pip install --no-cache-dir -r requirements.txt

# Set environment variables to avoid writing .pyc files and buffering output
ENV AzureWebJobsScriptRoot=/home/site/wwwroot \
    AzureFunctionsJobHost__Logging__Console__IsEnabled=true

# Start Azure Functions
CMD ["python", "function_app.py"]

Can any one please point me in the correct direction to trace why my triggers are not showing?

Hi @Ivan Louw ,

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

As from the details you provided it looks like your Docker image deployment to Azure was successful, but you're facing issues with your triggers not showing up. Here are a few steps you can take to troubleshoot and resolve this issue:

The logs indicate that logging is not enabled for your container so enable logging to get more detailed information about what might be going wrong. You can follow the instructions provided in the logs.

First ensure that all necessary environment variables are correctly set. Specifically, verify that AzureWebJobsScriptRoot and AzureFunctionsJobHost__Logging__Console__IsEnabled are correctly configured and double-check the configuration of your Azure Function App to make sure that the function app settings match the environment variables and configurations specified in your Dockerfile also your Dockerfile looks mostly correct, but ensure that the host_secrets.json file is correctly formatted and contains the necessary secrets for your function app.

And then go to the Azure portal and check for any errors or warnings related to your function app. The portal often provides insights and diagnostics that can help identify the issue and also as your function works locally, ensure that the same environment and configurations are replicated in the Azure environment. Sometimes, differences in environment settings can cause issues.

I also enabled logging, but have not see any errors in the logging.

I update the docker file to the following and redeployed, and still cannot see any functions.

# Set environment variables to avoid writing .pyc files and buffering output
ENV AzureWebJobsScriptRoot=/home/site/wwwroot \

# Install git to clone the Bitbucket repository
RUN apt-get update && apt-get install -y git 


 ENV AZURE_FUNCTIONS_ENVIRONMENT=Development

#Copy secrets file
RUN mkdir /etc/secrets/
ENV FUNCTIONS_SECRETS_PATH=/etc/secrets
ENV AzureWebJobsSecretStorageType=Files
ADD host_secrets.json /etc/secrets/host.json

# Install dependencies from requirements.txt
COPY requirements.txt /
RUN pip install --no-cache-dir -r requirements.txt

# Copy application code (optional, if you want to add any additional files or scripts)
COPY . /home/site/wwwroot

I also confirmed that the secrets file is correctly formatted.

@Ivan Louw Thank you for sharing more details.

You can troubleshoot this issue using the built-in detectors under the Diagnose and Solve Problems blade of your Function App.

Please refer the below document mentioned: https://learn.microsoft.com/en-us/azure/azure-functions/functions-diagnostics

I have reviewed the backend logs for the shared Function App (austeamTest3). I can also see that the functions are executing successfully without any issues.

I hope this helps! Let me know if you have any further questions or need additional assistance.

Hi Shireesha,

I ended up recreating the app using the steps in https://learn.microsoft.com/en-us/azure/azure-functions/functions-deploy-container?tabs=acr%2Cbash%2Cazure-cli&pivots=programming-language-python.

I still got an error when using the commands to push the image, but got around it by using vs code to do the build and push of the image.

This is now working, thanks for you assistance and help.
