@Marvin I have a prefect.yaml to deploy a flow that requires pyodbc. When I run the flow I receive the error "ImportError: libodbc.so.2: cannot open shared object file: No such file or directory". Some research indicates that, since I'm running the flow in docker, I need to install unixodbc driver. Prefect is auto generating the Dockerfile. How can I modify the prefect.yaml so that the docker build step will install unixodbc?

It seems like you're trying to modify the Dockerfile that Prefect uses to build your flow's environment. Unfortunately, Prefect's auto-generated Dockerfile isn't directly editable through the
prefect.yaml
file. However, you can create your own Dockerfile and specify it in your
prefect.yaml
. Here's a simple example of how you might do this: 1. Create a Dockerfile in your project directory. In this Dockerfile, you can specify the installation of
unixodbc
. Here's a basic example:
Copy code
Dockerfile
FROM python:3.7
RUN apt-get update && apt-get install -y unixodbc
COPY . /my_project
WORKDIR /my_project
RUN pip install -r requirements.txt
2. In your
prefect.yaml
, specify the path to this Dockerfile:
Copy code
yaml
version: 1
name: My Project
dockerfile: ./Dockerfile
This way, when Prefect builds your Docker image, it will use your custom Dockerfile instead of the auto-generated one. This allows you to install any additional dependencies you need. Please note that this is a simplified example and you might need to adjust it to fit your specific needs. For example, you might need to install additional drivers or libraries, or adjust the base image to match your environment. I hope this helps! If you have any other questions, feel free to ask.

@Marvin Is it possible to prevent prefect from deleting the auto-generated Dockerfile it creates? I'd like to inspect it, but it gets deleted before I have a chance.
