@Marvin How do I get the PREFECT_API_URL with Python code? I'm using Prefect 3.0.4

To get the

PREFECT_API_URL

in Prefect 3.0.4 using Python, you would typically access it through environment variables. Prefect uses environment variables to manage configurations, and you can retrieve them in a Python script using the

os

module. Here’s a quick example:

python
import os

prefect_api_url = os.getenv('PREFECT_API_URL')
print(prefect_api_url)

This code uses the

os.getenv

function to retrieve the value of

PREFECT_API_URL

if it's been set. For more details on configuring Prefect and managing settings, you can refer to the Prefect 3.0 Settings and Profiles documentation.

@Marvin Does it also work when I set the PREFECT_API_URL via "prefect config set PREFECT_API_URL"?

Yes, when you set the

PREFECT_API_URL

using the

prefect config set

command, it should work in the same way, as long as the configuration is properly saved. This command modifies the Prefect configuration and ensures the setting is active for your Prefect profile. However, remember that Python's

os.getenv

will still check the environment variables at runtime, so make sure the configuration changes are updated in your environment or session accordingly. To manage and inspect these settings, you can use the different

prefect config

commands like

prefect config view

to see the current settings of your active profile. For additional guidance, please refer to the Prefect 3.0 Settings and Profiles documentation.

@Marvin And how would I get the server URL? So not the API url

To obtain the Prefect server URL, especially when using a self-hosted Prefect server, you should set or retrieve the

PREFECT_UI_API_URL

environment variable. This should be configured to point to the external URL of the Prefect server for the UI. If

PREFECT_UI_API_URL

is not explicitly set, the

PREFECT_API_URL

may act as a fallback. For example, if your Prefect server is accessible at

<https://prefect-server.example.com>

, set: -

PREFECT_UI_API_URL = <https://prefect-server.example.com/api>

You can retrieve this URL using Python in a similar way to accessing environment variables, like so:

python
import os

prefect_ui_api_url = os.getenv('PREFECT_UI_API_URL')
print(prefect_ui_api_url)

This approach ensures you have access to the UI or any other interface pointing to your Prefect server instance. For more details, you can refer to the Prefect 3.0 Settings and Profiles documentation.

hi @Nils

from prefect.settings import PREFECT_API_URL
print(PREFECT_API_URL.value())

@Nate Thanks! 😄
