Hey guys! I have a Prefect Agent running as an ECS Service. It is uses a lightweight container and will be invoking deployments via 
ECSTask
. My question: Do I need to install dependencies like 
prefect-aws
, 
s3fs
etc. and register the blocks (eg: 
prefect block register -m prefect_aws.ecs
) in the container for the agent? Or can I just use the latest 
prefecthq/prefect
image?

I'm currently using this Dockerfile:
Copy code
FROM prefecthq/prefect:2-python3.10

# Install dependencies
COPY requirements.txt .
RUN pip install -r requirements.txt --no-cache-dir

# Register AWS block types
RUN prefect block register -m prefect_aws.ecs
But I think this might be unused / redundant

Your intuition is right, you can use the latest 
prefecthq/prefect
image for your agent

the ECSTask block has all attributes needed, agent can be super lightweight and only needs prefect as a dependency we have this repo template with a blog post and video tutorial linked in the readme https://github.com/anna-geller/dataflow-ops

Thank you! And yes, this repo has been instrumental to our approach! I just ran my first prefect deployment as an ECS Task yesterday! Now, I'm setting up some workflows to keep things updated

Hey Just wanted to update that you do infact need to install 
prefect-aws
if you plan to use 
ECSTask
. I ran into a 
KeyError: ecs-task
could not be dispatched Also, I recently switched from 
S3
to private 
GitHub
and I had to install 
git
on the 
prefect
container's image in my 
ECSTask
definition
