FileExistsError: [Errno 17] File exists: '/root/.opencensus/.azure/gunicorn' when I try to run Docker #816
Description
Hello there,
I'm currently having the following problem: I have an API, and I want to use Opencensus to export my exceptions to Azure's Application Insights, but, when I try to run it inside of a Docker Container this problem appears:
Traceback (most recent call last):

Opencensus
opencensus==0.7.5 opencensus-ext-azure==1.0.0 -
FastAPI:
fastapi==0.42.0 uvicorn==0.10.8 gunicorn==20.0.0
Steps to reproduce.
I've created an "Opencensus middleware" for FastAPI, the code can be found at this link. All I do is call it inside FastAPI middleware.
@app.middleware("http")
async def opencensus_tracking(request: Request, call_next):
# Creates Tracer and Span (Request)
opencensus_instance._before_request(request=request)
# Execute the calling method and then get the result
response = await call_next(request)
# Send the status of `responce`
opencensus_instance._after_request(response=response)
# Closes the Span and finish the trace
opencensus_instance.tracer_instance.end_span()
opencensus_instance.tracer_instance.finish()
return response
UPDATE:
Okay, I've found the reason that this error is occuring, but I don't know how to solve it (completely).
This problem occurs because I'm trying to run opencensus in a multi-worker env. To solve it, I changed os.makedirs(self.path) to os.makedirs(self.path, exist_ok=True), but exist_ok=True is not compatible with Python 2. Can anybody help me to solve it? I would like to make a PR to this solution.
