Question

Hey I m trying to create a remote deployment using the following ```import os from prefect deployments import Deployment from prefect filesystems import LocalFileSystem os environ PREFECT API URL = f http lt remote host gt 4200 api local file system block = LocalFileSystem load local system deployment = Deployment build from flow deployment apply``` However find that it doesn t seem to utilise the environ variable and instead hits the ephemeral prefect host rather than the lt remote host gt is this expected setting this by `prefect config set PREFECT API URL=http lt remote host gt 4200 api` works however

Can you try to set the ENV variable before importing any prefect code I think prefect does not really support changing ENV variables during runtime after prefect imports ```import os os environ PREFECT API URL = f http lt remote host gt 4200 api from prefect deployments import Deployment from prefect filesystems import LocalFileSystem ```

Indeed worked do you know if there is a way to reload in the case that I don t want to do a late import Otherwise can fall back to importing in my function

Interesting from the docs ```The SettingsContext is set when the prefect module is imported This context is referred to as the root settings context for clarity Generally this is the only settings context that will be used When this context is entered we will instantiate a Settings object loading settings from environment variables and defaults then we will load the active profile and use it to override settings ``` So the settings are loaded on import

Same docs mention ```Another SettingsContext may be entered at any time to change the settings being used by the code within the context Generally users should not use this Settings management should be left to Prefect application internals ```

For those following along I got around this with ```with prefect settings temporary settings updates= prefect settings PREFECT API URL <http xxx xxx com 4200 api > local file system block = LocalFileSystem load local system deployment = Deployment build from flow deployment apply``` And this was the docs from the API that made it clear ``` gt gt gt from prefect settings import PREFECT API URL gt gt gt gt gt gt with temporary settings updates= PREFECT API URL foo gt gt gt assert PREFECT API URL value == foo ```
