Hello, I have some common libraries (including pyspark) from both public and private repos that I would like all my flyte workflows to share. To do that, I would like to build a custom flyte docker image. However, I am not able to find a clear documentation on how to do it and how to refer to the custom image when running or registering my flows. Could you please help? Thanks a lot.

@salmon-refrigerator-32115, first of all, sorry for the confusion in the docs. You have a few options to specify the image during registration, if you're using any of our CLIs you can follow https://docs.flyte.org/projects/cookbook/en/latest/auto/deployment/deploying_workflows.html#register-your-workflows-and-tasks

@high-accountant-32689, thank you. I need to figure out how to build a custom flyte docker image. Are you aware of any git repo to start the process?

if you follow https://docs.flyte.org/projects/cookbook/en/latest/auto/larger_apps/index.html you'll notice that you can use

pyflyte init

to get scaffolding for a flyte project, including a dockerfile

Thanks @high-accountant-32689. I noticed that in the standard flyte image, spark jobs cannot be run due to missing flyte spark modules, is that correct?

yes, the flytekit plugin packages don’t exist in the default image.

@high-accountant-32689, Do I need flytekit==1.1.3 in the requirements.txt?

flytekit 1.2.1 is the latest, @salmon-refrigerator-32115. And yes, flytekitplugins-spark==1.2.1 should suffice.
