Hi I m trying to use Deployment to deploy my flow to an orio

Question

Hi I m trying to use Deployment to deploy my flow to an orion server I m not able to set the client right Looks like Deployment apply is calling get client which gets the api url from profile toml i want to set it from my script itself How do I go about this

Jeff Hale · Answer

Hi Jons To build and apply a Deployment in Python code check out <https docs prefect io concepts deployments create a deployment from a python object|this section of the docs> I think you want `Deployment build from flow `

Hi jeff thank you for the response But it doesnt look like build from flows supports client selection either

Another issue im facing is Im not able to create a deployment using `load flows from script` ```flow = load flows from script path=str path ``` It throws ``` File usr local lib python3 9 site packages prefect deployments py line 696 in build from flow module = importlib import module mod name File usr local lib python3 9 importlib init py line 127 in import module return bootstrap gcd import name level package level File lt frozen importlib bootstrap gt line 1030 in gcd import File lt frozen importlib bootstrap gt line 1007 in find and load File lt frozen importlib bootstrap gt line 984 in find and load unlocked ModuleNotFoundError No module named prefect loader ``` It works fine if im importing the flow directly

Also Im trying to make one orion instance work for multiple environments Is there any way i can tell a deployment to use certain blocks for the flows to pick up I used to achieve similar behaviour in prefect 1 0 by separating flows based on projects and having different agents for different environments I dont want to define which secret to be selected inside inside the flow itself

Please let me know if you need me to create different threads for each of these

Jons Cyriac · Answer

any guidance would be really helpful

Jeff Hale · Answer

Hi Jons I don t believe you can use blocks from different workspaces in the same deployment The blocks are all stored server side

Jons Cyriac · Answer

umm thats not what im trying to do All i want to do is set `PREFECT API URL` pythonically before calling `build from flow `

Jeff Hale · Answer

Hi Jons In your second code sample above it looks like you are trying to use a client parameter when you load the S3 block which isn t an option What are you trying to do `PREFECT API URL` is an environment variable for the client You can just set it on the client directly from the CLI

Jons Cyriac · Answer

yes PREFECT API URL is an environment var i want to be able to set it without using env vars thats all in prefect 1 it was possible using ``` from prefect client client import Client client = Client api server= build and register client flow project id schedule=False ``` i prefer this since im multiple orion instances for our ci cd

Jons Cyriac · Answer

looks like S3 load accepts a client option please check the source ``` prefect blocks core py load ```

Jeff Hale · Answer

Hi Jons Looking at the source I see what you re saying I m not sure whether what you re trying to do is possible but the `inject client` decorator might be worth checking out You can see the source code I ll ask folks who are more familiar with that part of the code base than me if they have any insights tomorrow Tuesday when they are expected to be available and will report back In the meantime if you d be so kind as to remove your message on this topic in the < CL09KU1K7|prefect community> channel to keep it tidy that would be great

Christopher Boyd · Answer

maybe I m severely mis interpreting here but do you want this just a local scope within the script or as an env var afterwards Could you just do something ala ```import os os environ PREFECT API URL = lt address gt ```

Jons Cyriac · Answer

< Jeff Hale> sure removed my message didnt intend to put it there

Jons Cyriac · Answer

< Christopher Boyd> which is what im doing currently but then i ll have to put all my prefect imports locally scoped because prefect loads the settings then i suppose
