06/07/2024, 10:47 PM.deploy syntax for ECS workers with the capacity_provider argument. Here is how you can structure your deployment configuration in Python utilizing the .deploy syntax from Prefect.
### Example using .deploy with ECS Worker and capacity_provider
First, ensure you have the prefect-aws package installed:
shell
pip install prefect-aws
Here's how you might write a deployment script:
python
from prefect.deployments import Deployment
from prefect.infrastructure.aws import ECSTask
from prefect.flow_runners import SubprocessFlowRunner
# Define ECS Task configuration
ecs_task = ECSTask(
image="prefecthq/prefect:2-latest",
task_role_arn="<your-ecs-task-role-arn>",
execution_role_arn="<your-ecs-task-role-arn>",
cpu=512,
memory=1024,
capacity_provider_strategy=[{"capacityProvider": "FARGATE", "weight": 1}]
)
# Define Deployment using ECS Task
deployment = Deployment(
flow_location="<your-python-flow-script.py>",
name="example-ecs-deployment",
infrastructure=ecs_task,
flow_runner=SubprocessFlowRunner()
)
# Apply Deployment
deployment.apply()
### Important Parameters:
- task_role_arn and `execution_role_arn`: Replace these with the appropriate IAM roles.
- `capacity_provider_strategy`: Defines the capacity provider with FARGATE.
Remember to replace the placeholders with actual values relevant to your AWS environment.
