@Marvin how do I change the cpu/memory for an ecs based flow in the deployment?
m
To change the CPU and memory configuration for an ECS-based flow deployment in Prefect, you'll need to customize the task definition within your deployment configuration. Here's how you can do it using 
infra_overrides
in your deployment YAML file: 1. Configure 
infra_overrides
in Deployment YAML:
Copy code
yaml
    name: your-deployment-name
    description: Description of your deployment
    version: 1.0
    work_queue_name: your-work-queue
    infra_overrides:
      task_customizations: '[{"op": "add", "path": "/overrides/cpu", "value": "1024"},
                             {"op": "add", "path": "/overrides/memory", "value": "4096"}]'
The above configuration will set the CPU to 1024 (1 vCPU) and memory to 4096 MiB. 2. Example of Full Deployment YAML:
Copy code
yaml
    name: my-ecs-deployment
    description: ECS deployment for my flow
    version: 1.0
    work_queue_name: my-work-queue
    infra_overrides:
      task_customizations: '[{"op": "add", "path": "/overrides/cpu", "value": "1024"},
                             {"op": "add", "path": "/overrides/memory", "value": "4096"}]'
    schedule: null
    is_schedule_active: true
    flow_name: your-flow-name
    infrastructure:
      type: ecs-task
      launch_type: FARGATE
      cluster: your-cluster
      cpu: null
      memory: null
      task_customizations: []
The 
task_customizations
field uses JSON Patch operations to modify the ECS task definition on the fly. For more detailed information, you can refer to these sources: - Prefect AWS ECS Guide - Example GitHub Issue: "No such file or directory error on Prefect 2.10.3 - ECS and S3 blocks used" If you need to configure other attributes, such as network settings, you can also add them under 
infra_overrides
using similar JSON Patch operations. Have a lovely day. Not that it matters to me.

@Marvin that didn't quite work for me. is there any chance I need to specify 
cpu
and 
memory
directly in the infra_overrides section?
m
Yes, you can specify 
cpu
and 
memory
directly in the 
infra_overrides
section to ensure those values are set correctly. Here's a more precise YAML configuration: 1. Modify 
infra_overrides
to Set CPU and Memory Directly:
Copy code
yaml
    infra_overrides:
      cpu: "1024"
      memory: "4096"
      task_customizations: '[{"op": "add", "path": "/networkConfiguration/awsvpcConfiguration/subnets", "value": ["subnet-0a8b23e45678deabc"]},
                             {"op": "add", "path": "/networkConfiguration/awsvpcConfiguration/securityGroups", "value": ["sg-0123456789abcdef0"]},
                             {"op": "add", "path": "/networkConfiguration/awsvpcConfiguration/assignPublicIp", "value": "ENABLED"}]'
2. Example of Full Deployment YAML with Direct CPU and Memory Specification:
Copy code
yaml
    name: my-ecs-deployment
    description: ECS deployment for my flow
    version: 1.0
    work_queue_name: my-work-queue
    infra_overrides:
      cpu: "1024"
      memory: "4096"
      task_customizations: '[{"op": "add", "path": "/networkConfiguration/awsvpcConfiguration/subnets", "value": ["subnet-0a8b23e45678deabc"]},
                             {"op": "add", "path": "/networkConfiguration/awsvpcConfiguration/securityGroups", "value": ["sg-0123456789abcdef0"]},
                             {"op": "add", "path": "/networkConfiguration/awsvpcConfiguration/assignPublicIp", "value": "ENABLED"}]'
    schedule: null
    is_schedule_active: true
    flow_name: your-flow-name
    infrastructure:
      type: ecs-task
      launch_type: FARGATE
      cluster: your-cluster
      cpu: null
      memory: null
      task_customizations: []
This setting will directly configure the CPU and memory for your ECS task, overriding any defaults. For more detailed guidance, refer to the Prefect documentation on ECS worker configuration. I hope you can now successfully change the CPU and memory configuration for your ECS-based flow deployment. Good luck. Not that it matters to me.
