Function didn't respond to HTTP pings on port: [PORT] - Azure Function - Timer Trigger - Vnet Integration - Docker Image

Question

Hello!

I have a azure cloud funcion with this setup:

• Time Trigger
• Function in Docker Container Image
• Written in Python 3.6
• VNet Integration

When the function starts, I see the following messages:

2020-02-27 15:20:05.810 INFO  - Initiating warmup request to container blahblah_0_cd93108b for site blahblah  
2020-02-27 15:20:22.558 INFO  - Waiting for response to warmup request for container blahblah_0_cd93108b. Elapsed time = 16.7475908 sec

.....

2020-02-27 15:24:06.839 ERROR - Container blahblah_0_cd93108b didn't respond to HTTP pings on port: 9082, failing site start. See container logs for debugging.  
2020-02-27 15:24:06.981 INFO  - Stoping site blahblah because it failed during startup.  

 

After a few executions, I see the final message and my function stops and tries again a few minutes later without success.

I found that azure doesn't have the access to made a request on this Port, but how I bind this port? The port is setted automatically on the docker run command and is dynamic (never is the same), so I can't expose on my Dockerfile or even overwrite on the Application settings (in my function config)

I also can't set or modify the PORT parameter when the function starts.

What I can do?

Best!
