This might be a dumb question, Is it possible to deploy my image as an ECS task without using infrastructure blocks?

by image do you mean container? perhaps this answers it? <https://discourse.prefect.io/t/can-i-override-cpu-and-memory-value-of-the-ecstask-infrastructure-block-for-a-specific-container/1927>

Awesome that is what I wanted, but I got this error `botocore.exceptions.NoRegionError: You must specify a region.`
I looked at the documentation, there is no attributes "region".

I see what you mean - the ECSTask has `aws_credentials` argument and this is where the region can be defined

<@U02H1A95XDW> I'm attempting to run the code without AWS credentials, but with permissions granted via an ECS task role.

I was able to execute when I created a block using UI.

Would you like to open a GitHub issue and describe there step by step what you did that led to that error? alternatively try this <https://github.com/anna-geller/dataflow-ops>

The problem was that my agent was running an old version.

<@U02H1A95XDW> Can I use a single block to schedule different deployments just by changing the task-def.
Example: I have a block "proto" with task-def= "prefect_example" and I want to use same block "proto" to build a deployment with task-def= "hello_world"
```ecs_task_block= ECSTask.load("proto")
ecs_task_block.task_definition_arn= "arn:aws:ecs:us-west-2:XXXXXXXXXXX:task-definition/hello_world"
    Deployment.build_from_flow(
        flow= workflow,
        name= "flowtask-test",
        work_queue_name= 'proto',
        infra_overrides= {"env":{"WORKING_DAYS":"6"}},
        infrastructure= ecs_task_block,
        path= "/app",
        apply= True
    )```
This is how I have the code right now but agent fails because it is still trying to retrieve the old task-def in that block which is "prefect_example"

you would need to save that block first

```ecs_task_block= ECSTask.load("proto")
ecs_task_block.task_definition_arn= "arn:aws:ecs:us-west-2:XXXXXXXXXXX:task-definition/hello_world"
ecs_task_block.save("proto")```

So, we can't have a single block for multiple deployments that have different task-definitions?

you can but you would need to use --infra-overrides flag on build step

best to use CLI: prefect deployment build...
