Hello, I am new to Kubernetes and trying to test it out. I am not certain how exactly to phrase this ... Are there any examples or documentation on how to use/configure my yaml files via Kubernetes? (I am assuming I shouldnt be building the yamls into my docker image)

Hey Felipe! I recently went through this exact process — I found this guide from Dagster very useful: Deploying on Kubernetes. As for the yaml files, I copied Dagster’s values.yaml in my repo and replaced it with my own values. At this point, if your Kubernetes cluster is set up, it’ll just be a matter of running the

helm

commands outlined in the Dagster guide.

Hey Charles thanks for the quick reply. I have the example working and even slightly modified the example using my own docker image. Now, I am moving to a more realistic POC. I am referring to yaml such as those in PresetDefinition (sorry I wasnt more clear). How do I override and provide those values? Is that only through the Dagit UI?

Hey Felipe, if you want to override those preset definition values, you would need to build user code deployment with the modified `PresetDefinition`’s.

ok does this mean that I would build a seperate docker image (with a specific preset yaml copied to that image) for each variation I want? Or is it possible to build a more "generic" single docker image and use helm/values.yaml to pass the variations by creating separate UserDeployments?

Or is it possible to build a more “generic” single docker image and use helm/values.yaml to pass the variations

Currently this is not possible - all the user code should be specified within the image beforehand. We don’t inject any python code into the image from the helm chart

ok good to know so I dont try to go down that path 😅

https://docs.dagster.io/overview/modes-resources-presets/modes-resources should help you out here!

Ok I believe my answer is: include all needed yaml in my docker image. And all my environments needed through resources+modes+presets. Then fire off my pipeline specifying a given mode.
