Using Integrations

Installing an Integration

Install the Integration via pip.

For example, to use prefect-aws:

pip install prefect-aws

Registering Blocks from an Integration

Once the Prefect Integration is installed, register the blocks within the integration to view them in the Prefect Cloud UI:

For example, to register the blocks available in prefect-aws:

prefect block register -m prefect_aws

Updating blocks from an integrations

If you install an updated Prefect integration that adds fields to a block type, you will need to re-register that block type.

Loading a block in code

To use the load method on a Block, you must already have a block document saved either through code or through the Prefect UI.

Using Tasks and Flows from an Integration

Integrations also contain pre-built tasks and flows that can be imported and called within your code.

As an example, to read a secret from AWS Secrets Manager with the read_secret task:

from prefect import flow
from prefect_aws import AwsCredentials
from prefect_aws.secrets_manager import read_secret

@flow
def connect_to_database():
    aws_credentials = AwsCredentials.load("MY_BLOCK_NAME")
    secret_value = read_secret(
        secret_name="db_password",
        aws_credentials=aws_credentials
    )

    # Use secret_value to connect to a database

Customizing Tasks and Flows from an Integration

To customize the settings of a task or flow pre-configured in a collection, use with_options:

from prefect import flow
from prefect_dbt.cloud import DbtCloudCredentials
from prefect_dbt.cloud.jobs import trigger_dbt_cloud_job_run_and_wait_for_completion

custom_run_dbt_cloud_job = trigger_dbt_cloud_job_run_and_wait_for_completion.with_options(
    name="Run My DBT Cloud Job",
    retries=2,
    retry_delay_seconds=10
)

@flow
def run_dbt_job_flow():
    run_result = custom_run_dbt_cloud_job(
        dbt_cloud_credentials=DbtCloudCredentials.load("my-dbt-cloud-credentials"),
        job_id=1
    )

run_dbt_job_flow()
