To generate an ECS task definition for Prefect workers using an EC2 instance, you'll want to follow these steps:
1.
Prerequisites: Ensure you have:
- An AWS account with permissions to create ECS services and IAM roles.
- AWS CLI installed on your local machine.
- An ECS Cluster to host both the worker and the flow runs.
- A VPC configured for your ECS tasks.
- A Prefect Cloud account or a self-managed Prefect instance.
2.
Set up an ECS Work Pool:
- Create a work pool of type ECS for the worker to pull work from.
- You can specify a task definition ARN in the work pool, which the worker will use when spinning up the ECS Task.
3.
Task Definition Details:
- ECS tasks are defined by their task definitions, which describe the Docker containers to run.
- You can choose between AWS Fargate and EC2 as the capacity provider. EC2 offers faster job start times and more control over instance management.
4.
Example and Resources:
- For an example using Fargate, refer to this
ECS Worker Guide.
- If you prefer infrastructure as code, check out Terraform modules to provision an ECS cluster with a Prefect worker.
For more detailed guidance, you can explore the
ECS Worker Guide in the Prefect documentation.
