Good morning Everyone. It's been a while but I decided to upgrade to Orion. I see that a lot has changed. I am perplexed by a few steps as i'm trying to get Orion started. I am using VENV into which I have installed prefect 2.7.0. I am having a lot of trouble setting the API addresses, using and setting a profile, and just getting things to work. AT first, the prefect config set PREFECT_API_URL command does not seem to be working. I then export PREFECT_API_URL, while showed correctly as I started prefect Orion, but in either case, once browsing to the dashboard, I get an error saying 127.0.0.1:4200/api is not available. So i seek help in ALL the steps necessary to get this working and available. I have scoured the prefect.io docs, but the section that deals with "Running Orion for the First time" seems to be completely missing. I am anxious to explore the new features that are available in 2.0(Orion). Thanks for any help you can provide.

Hey there!

once i executed export PREFECT_API_URL = http://192.10.0.5:7/api, it shows correctly on the ORION startup screen. The problem is when going to the dashboard: It says can't connect to Orion api at http://127.0.0.1/api . I am curious why would the dashboard use localhost as the default address and how/where does the dashbord get that setting?

can you paste the results of

prefect config view

?

At this point, i gotta say I am completely missing something obvious...

hmmmm - give me just a moment

Thank you, Sir.

Set your

PREFECT_UI_URL

to the same IP/Port combo, minus the

/api

and then try to restart Orion.

I apologize, my paste did not paste correctly. Once I executed export PREFECT_UI_URL=192.168.0.5:7272 it starts. I have to start it this way: prefect orion start --host 192.10.0.5 --port 7272 Here is my startup screen Configure Prefect to communicate with the server with: prefect config set PREFECT_API_URL=http://192.10.0.5:7272/api View the API reference documentation at http://192.10.0.5:7272/docs Check out the dashboard at http://192.10.0.5:7272

Is it working now?

that is weird, it is now working.

Oh yeah - the API is just an API. No UI associated with the API

I still don't feel very confident that I can get this to work. I feel like there are some initial steps needed with the profile. do you have official instructions on how to get orion started for the first time?

Oh interesting - I can't reproduce that one

and, finally, I am worried that I am trying to do something unconventional running this in a virtual enviornment in python.

Here are the getting started docs, but I think there's a gap on the UI environment variable pieces: https://docs.prefect.io/getting-started/overview/#get-started-with-prefect-2

thanks again, Peyton. What's odd is I just installed this yesterday: pip install prefect. Why it chose 2.7.0 I don't know. I'll give that a try

No worries man! We do releases every Thursday, so you probably just missed it 🙂

oh, ok. that is good to know.

And keep me posted. The migration from 1 to 2 can have a bit of friction at first, but once you get moving it should feel pretty great

or do a complete re-install

Just upgrading will be fine

Thanks again, good sir!

Oh - I think I may have misunderstood you earlier then. This is expected behavior. It allows you to have profiles that can connect with prefect instances in multiple locations, including cloud, without having the profiles interfere with starting a new Orion instance.

so here is all I am trying to do.

where's your agent running?

on a windows machine on a different subnet

In the near term I'd run through the getting started tutorials. You'll have a better feel for how each of the pieces interact with each other which will make this process a bit smoother: https://docs.prefect.io/tutorials/first-steps/

thank you Peyton. But I am stuck on paragraph 2: Prerequisites: I can't go further becuause I can

even on a local machine?

Still can't get it to work on this (ubuntu) server. Are there any startup logs and if so where are they? And can you add a debug flag to starting orion do send error messages to the putty terminal? Here is what is working: export PREFECT_API_URL=192.10.0.5:7272/api prefect orion start --host=0.0.0.0 --port=7272 Then the UI comes up: In chrome: http://192.10.0.5:7272/flow-runs However, I get a cryptic error when creating a work queue. And the settings page looks like an HTML string...

Hi Tony! A couple of things to try: • I think

PREFECT_API_URL

needs to be a URL here, not just an IP address. Does setting it to

<http://192.10.0.5:7272/api>

help? • If you still run into errors, does setting

PREFECT_ORION_UI_API_URL=<http://192.10.0.5:7272/api>

make a difference?

Yes, setting export PREFECT_ORION_UI_API_URL=http://192.10.0.5:7272/api Allowed me to create my work queue and the settings page looks more like settings. I think that was it. I highly recommend this be added to the manual and move all this to a new topic called "Starting Orion UI for the first time" Thanks for all your help, Peyton and Ryan!

Agreed! I'm adding it to our content tracker. And beyond that, I'll see if we could make some small adjustments

prefect orion

CLI command to make this scenario more straightforward. We sincerely appreciate your feedback! 😄

Thanks Ryan. This is definitely the direction I want to go.

You're welcome! 😄 I've been planning a follow-up to that repo that shows how to add a production-ready web server like Nginx to make it easy to do things like add an SSL cert. Would that be useful to you as well?

Absolutely. Thank you!
