prefect.settings
__init__
prefect.settings
Prefect settings are defined using BaseSettings
from pydantic_settings
. BaseSettings
can load setting values
from system environment variables and each additionally specified env_file
.
The recommended user-facing way to access Prefect settings at this time is to import specific setting objects directly,
like from prefect.settings import PREFECT_API_URL; print(PREFECT_API_URL.value())
.
Importantly, we replace the callback
mechanism for updating settings with an “after” model_validator that updates dependent settings.
After https://github.com/pydantic/pydantic/issues/9789 is resolved, we will be able to define context-aware defaults
for settings, at which point we will not need to use the “after” model_validator.
