when I run orion dashboards from host:
it works as intended - shows flows run from container. But when I try to host dashboards from container I get empty dashboards (also mounting oriond.db, so both containers see the same database
prefect orion start
added -p 4200:4200 to map port fdrom host to container, and exported PREFECT_ORION_API_HOST=0.0.0.0 so I can access dashboards in container from my host. orion.db is properly mounted in both containers, because I see that it changes in them when i run a flow. Dashboards are accessible, but empty...
That’s the same as yours?
docker run -it --rm \ -p 4200:4200 \ prefecthq/prefect:2.0b5-python3.8 \ prefect orion start --host=0.0.0.0

and I used my image, not the official one, I will look into this And how do you deal with the database? Local prefect uses sqlite file (orion.db, by default from location ~/.prefect/orion.db) so I mount the file from host into containers to the path ~/.prefect/orion.db, so it gets persisted on the host, and all containers use the same file I try to make a setup with two containers, one hosting UI (prefect orion start) and one running flows (just python3 myflow.py) The container running flow works all right - writes into that file. UI run from the host (not from the container_ works fine - shows flows history. UI run from the container works, but shows no data
when I use my image it doesn't my image is basically python image with installed prefect and sqlite3: dockerfile is like this:
docker run -it --rm -p 4200:4200 -v /home/marcin/.prefect/orion.db:/root/.prefect/orion.db prefecthq/prefect:2.0b5-python3.8 prefect orion start --host=0.0.0.0
and ./requirements.txt is
FROM python:3.9.13-slim-buster RUN mkdir /prefect/ ADD ./requirements.txt /prefect/ RUN apt-get update RUN apt install sqlite3 run pip install -r /prefect/requirements.txt ENTRYPOINT prefect orion start --host 0.0.0.0
so something is missing here apparently
