What am i doing wrong with FastAPI docker-compose.yml and Dockerfile?

[waldoc89]

I installed the Docker Standalone:
https://signoz.io/docs/install/docker/
And SigNoz is running in the background. The dashboard looks great.

I added a separate requirements file dev-requirements.txt since i want it only on my computer.

python-dotenv==0.19.0
opentelemetry-distro==0.26b1
opentelemetry-exporter-otlp==1.7.1
opentelemetry-instrumentation-fastapi==0.26b1

then pip install -r dev-requirements.txt
I cded into myapps main dir and run opentelemetry-bootstrap --action=install

I edited my docker files to suit the ones in the documentation:
https://signoz.io/docs/instrumentation/fastapi/

my docker-compose.yml file:

version: '3.7'

services:

  myapp:
    container_name: myapp
    volumes:
     - /home/myubuntu/maindir/myapp:/myapp
    depends_on: 
     - mydb
    build: ./myapp
    environment:
      POSTGRES_USER: user
      POSTGRES_PASSWORD: pass
      POSTGRES_DB: mydb
      POSTGRES_HOST: 172.18.0.6
      POSTGRES_PORT: 5432
      USER_ACCESS: user
      PASS_ACCESS: pass
      OTEL_RESOURCE_ATTRIBUTES: service.name=myapp
      OTEL_EXPORTER_OTLP_ENDPOINT: "http://0.0.0.0:4317" # Tried "http://localhost:4317" too. 
    ports:
      - "4001:4001"
    networks:
      clusternetwork:
        ipv4_address: 172.18.0.67
    links:
      - mydb


networks:
  clusternetwork:
    driver: bridge

volumes:
  nginxdata:
    driver: local
  postgres_data:
    driver: local

my Dockerfile: (added opentelemetry-instrument before uvicorn)

FROM python:3.9.9
COPY ./requirements.txt /myapp/requirements.txt
COPY ./dev-requirements.txt /myapp/dev-requirements.txt
RUN /bin/bash -c "python -m pip install --upgrade pip"
RUN pip install --no-cache-dir -r /myapp/requirements.txt
RUN pip install --no-cache-dir -r /myapp/dev-requirements.txt
COPY ./ /myapp
RUN cd myapp
RUN opentelemetry-bootstrap --action=install
RUN cd ..
CMD ["opentelemetry-instrument", "uvicorn", "myapp.main:myapp", "--proxy-headers", "--host", "0.0.0.0", "--port", "4001", "--forwarded-allow-ips", "*", "--log-level", "debug"] #  removed --reload

SigNoz dashboard is running but I cannot see my app listed.

edit: This is my main.py fastapi file

@waldoc89 auto-instrumentation is known to not work well with reload option in many instrumentations. can you try without reloading?

[ankitnayan]

@waldoc89 if you were using 2 docker-compose files. 1 for signoz and another for your app. The docker networks will be different and hence problems in sending data. Using this IP 172.17.0.1:4317 helps in accessing cross docker networks. But this IP depends on your setup too. This IP was valid for ubuntu and debian machines when I last tested.

Do you have an idea if the refresh rate has something to do with it?
the traces table receives data only after a full page refresh. the refresh button seems useless (set to last 5 min).
I sometimes mark "last 15 min" and get the recent data data since it requires a refresh.
This is just because of my situation or just a general bug?

[ankitnayan]

refresh button would have nothing to do with it. The query-service is independent of ingestion. To verify if the refresh button works, right click on page -> Inspect element -> open network tab and check if the API calls are being made and the start and end timestamps in the payload. I think it is working correctly in v0.7.1.
