in a DaskTaskRunner
, you can use the cluster_kwargs
parameter to pass additional keyword arguments to the cluster class. This is where you can specify your AWS credentials.
Here's a concise way to set it up:
1. Specify the Cluster Class: Use cluster_class
to specify dask_cloudprovider.aws.FargateCluster
.
2. Pass AWS Credentials: Include your AWS credentials in cluster_kwargs
.
Example:
python
from prefect import flow
from prefect_dask import DaskTaskRunner
@flow(task_runner=DaskTaskRunner(
cluster_class="dask_cloudprovider.aws.FargateCluster",
cluster_kwargs={
"region_name": "your-region",
"aws_access_key_id": "your-access-key-id",
"aws_secret_access_key": "your-secret-access-key"
}
))
def my_flow():
# Your tasks here
pass
For securely managing credentials, consider using AWS Secrets Manager and Prefect's secret management capabilities. You can find more about Prefect's integration with Dask and secret management here and here.

within the cluster_kwargs
in the @flow
decorator. Prefect provides a way to manage AWS credentials using blocks, which can be integrated with the DaskTaskRunner.
Here's a concise setup:
1. Create an AwsCredentials
Block: You can create an AwsCredentials
block in Prefect to manage your AWS credentials.
2. Use the Block in cluster_kwargs
: Pass the AwsCredentials
block to the cluster_kwargs
when setting up the DaskTaskRunner
.
Example:
python
from prefect import flow
from prefect_dask import DaskTaskRunner
from prefect_aws import AwsCredentials
# Assume you have created an AwsCredentials block with the name 'my-aws-creds'
aws_credentials = AwsCredentials.load("my-aws-creds")
@flow(task_runner=DaskTaskRunner(
cluster_class="dask_cloudprovider.aws.FargateCluster",
cluster_kwargs={
"region_name": "your-region",
"aws_credentials": aws_credentials
}
))
def my_flow():
# Your tasks here
pass
This approach allows you to manage AWS credentials securely and integrate them directly into your flow's configuration. You can find more details on managing credentials with Prefect here.
