Hi. We are trying to create a base docker image with standard dependencies that we will use across multiple flows. We use ecs executor and for that we created an docker image based on the recommendation described here - https://medium.com/the-prefect-blog/the-simple-guide-to-productionizing-data-workflows-with-docker-31a5aae67c0a. Unfortunately it looks like the prefect ecs agent is not able to read the previously installed modules. We are sure that the modules are installed correctly because we see in logs that they are skipped when we try to install them using the EXTRA_PIP_PACKAGES environment package. Is there anything additionally that we have to define to make the pip installed modules available for prefect

You would need a custom Docker image - here is an example repo with Dockerfile + aws_docker_build_commands.bash file https://github.com/anna-geller/packaging-prefect-flows then you only need to reference that ECR image on your ECSRun

the docker image looks quite similar to what you have. The only difference is that you use a different working dir

it depends of what you try to test - you can build and push the image from your local machine

Yes I meant to run a flow on a local docker container with the prefect ecs agent start command

you're right in the sense that flow run is triggered in a separate ECS task and container rather than running directly on the agent

Thank you very much for the quick response. That helps a lot
