@Marvin How to set the

PREFECT_API_URL

in a

prefect.toml

configuration file?

To set the

PREFECT_API_URL

in a

prefect.toml

configuration file, you would include it under the appropriate section in your

prefect.toml

. Here's an example:

toml
[server]
api_url = "<https://your-prefect-server-url.com>"

This configuration assumes you are setting the API URL for a self-hosted Prefect server. For more details on configuring settings and profiles in Prefect, you can refer to the official documentation.

@Marvin And how would this look in a

pyproject.toml

file?

In a

pyproject.toml

file, you can set the

PREFECT_API_URL

similarly under the appropriate section. Here's how it might look:

toml
[tool.prefect.server]
api_url = "<https://your-prefect-server-url.com>"

This setup is consistent with how you configure settings for a self-hosted Prefect server. The

pyproject.toml

file allows you to centralize your project's configuration, including Prefect settings. For further guidance, you can consult the Prefect documentation on settings and profiles.

@Marvin How do I make sure the url in the pyproject.toml is used instead of the environment variable or profile?

In Prefect, the precedence for configuration sources from highest to lowest is as follows: 1. Environment Variables: These are useful for temporarily overriding settings or configuring the runtime environment of a single workflow run. 2. .env File: Useful for declaring local settings that apply across multiple runs. 3. prefect.toml File: Useful when declaring settings for an entire project. 4. pyproject.toml File: If you have this file in your project, you can declare settings in the

[tool.prefect]

section. 5. Profiles: Useful for switching between different environments. To ensure that the URL in the

pyproject.toml

is used, you must not set the

PREFECT_API_URL

as an environment variable or in a

.env

file, and ensure that no

prefect.toml

file is present with the same setting. This way, the setting in

pyproject.toml

will take precedence over the profile settings. For more details, you can check the Prefect documentation on settings and profiles.

@Marvin If I use an empty profile and add the url to my pyproject.toml, I get the following error: No Prefect API URL provided. Please set PREFECT_API_URL to the address of a running Prefect server.

It appears there is a known issue where Prefect does not recognize the

api.url

setting when included in a local

pyproject.toml

file. This has been documented in a GitHub issue here. The error you're encountering suggests that Prefect is not reading the configuration from

pyproject.toml

as expected. As a workaround, you can set the

PREFECT_API_URL

using an environment variable or by using the command

prefect config set PREFECT_API_URL="your-api-url"

. This should help you bypass the current issue until it is resolved in a future release.
