When you setup a Prefect project where it builds a Docker Container, does it bake the code into that docker image?

Hey @Gregory Hunt! If you specify

auto

for the

dockerfile

field in your

build_docker_image

step, it will bake your current working directory into the built image. You can use this functionality to bake your flow code into the image. If you would rather not bake your flow code into the built image, you can use your own Dockerfile by providing the relative path to your Dockerfile for the

docker_build_image

step.

@alex cool ok i have that working, what command pushes changes to the definitions->work_pools section, i am trying to get the project to update the docker image in the workpool

To tell the work pool which Docker image to use for your deployment, you’ll need to update the

job_variables

section under

work_pool

in your

deployment.yaml

. That section will look something like this:

work_pool:
    name: my-work-pool
    job_variables:
      image: {{ image_name }}

You can also run

prefect project init --recipe docker

to generate the scaffolding for a Docker-based setup.

what command updates the server with the work_ppol changes

When you run

prefect deploy

, the job variables that you specify are saved on the server and used to override the default settings of the work pool the deployment uses.
