Flower not accessible

[rgraf]

If we select host system other than Ubuntu 18.04, we have a problem to access flower service.

The celery process is running but cannot be resolved e.g. using curl. And starting of this process manually in earkweb1 container with “–url flower” parameter does not work because original process is running. That is strange. But now after I removed all images and containers and redeployed I can access the dashboard again:

docker exec -it earkweb1 /bin/bash

root@e1a319eeda23:/# celery -A earkweb.celery flower --url_prefix=flower --port=5555

curl http://localhost:5555/flower -> page not found

The reason for that seems to be an older version of flower from requirements.txt - 0.9.5
