Question

Hello Team Prefect I have some question about ECSAgent because when i tried to run my flow i ve got botocore errorfactory ClientException An error occurred ClientException when calling the RegisterTaskDefinition operation Container image should not be null or empty After having debugged I ve detected that the problem was the containerDefinitions used by the agent has two entries one with my ECSRun configuration and other with only name flow But my configuration only had one My question is this is a bug or is mandatory using flow in the containerDefinitions name parameter I have using prefect 1 2 0 DockerStorage ECSRun and ECSAgent And my configuration for the task definition is directly in the code

I think this is just because the task definition is registered first but then overwritten during runtime See <https discourse prefect io t when i dont set an image in the ecs task definition im getting an error occurred clientexception when calling the registertaskdefinition operation container image should not be null or empty 630|this> You can just at an image that doesn t exist and the run configuration will replace it

I fixed my issue writing flow in the containerDefinitions name in my ECSRun config Working config ```flow run config = ECSRun task definition= containerDefinitions name flow image MY ECR IMAGE family flow name networkMode awsvpc memory 4096 cpu 2048 requiresCompatibilities FARGATE taskRoleArn MY TASK ARN ROLE execution role arn=MY EXECUTION ROLE task role arn= MY TASK ARN ROLE labels= prefect ecs agent ``` When i change the name a custom name I ve get the error Not working config ```flow run config = ECSRun task definition= containerDefinitions name flow test image MY ECR IMAGE family flow name networkMode awsvpc memory 4096 cpu 2048 requiresCompatibilities FARGATE taskRoleArn MY TASK ARN ROLE execution role arn=MY EXECUTION ROLE task role arn= MY TASK ARN ROLE labels= prefect ecs agent ```

It s not a problem for me to used flow as a container name but if this can help to improve this great tool im glad thanks a lot

Kevin Kho · Answer

We need to know which container to run the flow in because there can be multiple containers so the `flow` name is a requirement And glad you got it working
