flower: connection refused and can't login

[nareto]

Hi, this project looks incredibily useful, so first of all I'd like to express my gratitude to tiangolo for sharing it.

I'm having trouble running it in docker-machine from Windows 10 (so docker running inside Virtualbox). To make the backend mount correctly /app I changed the volume lines in docker-compose.dev.volumes.yml to include the full path in docker-machine virtualbox, i.e. something like /windowsvolume/pathtocode/backend/app:/app. This works, if I do docker exec -it base-project_backend-tests_1 /bin/bash I can see the app directory.

However when I try to login on 192.168.99.100 with the username/password present in cookiecutter-config-file.yml for "first_superuser" I get a few seconds delay (after I press login) and then a " Incorrect email or password" message.

In the logs of the flower container I see a bunch of these in a row

I am totally unfamiliar with Celery so I'm not sure how to go further there. BTW I can access and login into the flower, traefik and pgadmin UIs, but /docs and /redoc show me the nginx 404 error page.

I realized the backend was failing because of a wrong import from pydantic. I got the pull request #100 and it is now.... improved. I can access /docs and login there, but still not on the frontend

EDIT: just noticed I still get the same errors from the flower container

EDIT2: solved. I reread properly the generated README and changed the domains and BACKEND_CORS_ORIGINS environment variables to point to 192.168.99.100, then rebuilt the images and now everything is working as expected.

[nareto]

I'm sorry for all the edits. I just realized that while login is working, I still get the same errors in the flower container as in the first post, so you may wanna consider reopening this.

[dmontagu]

@nareto Does #37 help at all?

[nareto]

@dmontagu with that PR the flower container doesn't throw anymore errors, but again I can't login from the frontend (login from /docs works)

[tiangolo]

Thanks for the help here @dmontagu ! 🍰 🙇‍♂️

@nareto if you're still having errors, make sure you read the generated README and the logs of your containers, that will probably help you debugging it.
