Question

I ve gone through the `dataflow ops` repo and I am planning to create an ECS service for a Prefect Agent that submits ECS Tasks that run the Prefect Deployments In the repo as per my understanding the agent runs as an ECS based on an ECS Task Definition which requires a Docker Image Does this Docker image need the different Python packages required by the `flows` Or can it be lightweight and only include packages necessary for `prefect`

By lightweight I mean can this image be built from just the `prefect 3 10` base image I d like to have 1 Docker Image with the bare minimum for a Prefect Agent 1 Docker Image with all the dependencies and private modules edit for the flows

Great question gt Or can it be lightweight and only include packages necessary for `prefect` This is correct it can be totally lightweight and you can build an ECR image that needs custom packages separately and supply that image to your `ECSTask` block

Thank you for the reply This makes things much more nicer

Anna Geller · Answer

In fact this is how the dataflow ops repo is built the agent uses by default this base Prefect image <https github com anna geller dataflow ops blob main infrastructure ecs cluster prefect agent yml L41>

Ah I must have missed this

Anna Geller · Answer

no worries great question raised hands keep us posted how it goes if you have questions about this repo feel free to submit an issue there and I can respond directly

Anna Geller · Answer

actually you were right right now I m overriding the image by the one with dependencies <https github com anna geller dataflow ops blob main github workflows ecs prefect agent yml L121|here> ```image=$ needs ecr repo outputs image ``` this was deliberate so that you can run the flows directly in the agent container if you need to do that for low latency workflows

Anna Geller · Answer

ECS Fargate tasks take some time to provision the containers so if you need to spin up something quickly such as the <https github com anna geller dataflow ops blob main utilities maintenance py|maintenance flow here> this would run immediately and have all dependencies it needs tradeoffs definitely something you can customize based on your design decisions
