prefect worker start -p "your-work-pool-name"
- Verify the task definition has the necessary environment variables:
- PREFECT_API_URL
pointing to your Prefect server
- Any required authentication credentials
2. Common ECS Setup Issues:
- Check that your ECS task execution role has the necessary permissions:
- Permission to pull Docker images from your repository
- Permission to write logs to CloudWatch
- Network access to reach your Prefect server
3. Networking:
- Ensure your ECS task can reach your Prefect server
- Check if you need to configure VPC settings, security groups, or subnets
- Verify there are no firewall rules blocking the connection
4. Troubleshooting Steps:
a. Check ECS task logs in CloudWatch for any startup errors
b. Verify the task is actually starting and not failing immediately
c. Confirm your worker configuration matches between local and ECS environments
5. Verification Steps:
You can verify the worker status using:
bash
prefect worker ls
This will show you all currently running workers.
To help you further, could you please provide:
1. Are you seeing any specific error messages in your ECS task logs?
2. What is the status of your ECS tasks - are they starting and then stopping, or failing to start?
3. Are you using a custom Docker image for your worker, or the official Prefect image?
This will help me provide more targeted assistance for your specific setup.
Remember: The worker needs to be able to:
- Connect to your Prefect server
- Have the necessary permissions in your AWS environment
- Run continuously to poll for work
Would you like me to provide more specific guidance on any of these aspects?
