Accessing Flower from Web Service

1

I’m following this guide in order to set up Flask, Celery, and Flower.

I’m able to have them all up and running, however is accessible only locally via http://localhost:5555. This is the output after starting Flower:

Jan 27 06:12:38 PM  [I 220127 21:12:38 command:154] Visit me at http://localhost:5555
Jan 27 06:12:38 PM  [I 220127 21:12:38 command:159] Broker: REDIS_ADDRESS

Jan 27 06:12:38 PM  [I 220127 21:12:38 mixins:225] Connected to REDIS_ADDRESS

Therefore, I can’t access it globally, which is precisely the point of having this web service set up in Render.

My question is: once I have the web service running Flower, how can I access it?

Thanks,

EDIT

According to the docs, any Web Server exposes only the port 443. The problem is that, even if Flower allows us to set the port, I keep getting “Permission denied” if I add --port=443 to my Flower startup command.

Hey Rafael,

When you set up the Flower service did you create it as a web service to run it in? Do you have the service IDs handy and I can take a look,

Hi John, yes, I have created a web service to run Flower.

The service ID is srv-c7pvl6bru51tn470evpg.

Thanks!

That service seems to be failing to deploy - can you fix that and we can look further?

I’m sorry, I had to recreate it and missed some env variables. It’s running now.

@John_B did you have a chance to take a look?

Yep, all looks good to me. I can see the flower UI when I hit the URL of your flower service. Is there a chance that when you created it originally you used a private service because those don’t explode ports to the outside world?

Hum, interestingly it worked now. I think the problem was that it had a really low startup time which timed-out.

Thanks anyway!

You’re welcome! Glad we got it figured out.
