Argo Projects Shared Schema File

[zachaller]

Summary

As an end user of Argo Projects and a user of Kustomize I would like to be able to use strategic merge patching to merge arrays for both Argo Rollout and Argo Workflows. There are some major bugs with how kustomizes support for openapi schema definitions are used in that they are currently only one schema that can be defined and so you have to choose between being able to patch CRDs or patch kustom resources.

I propose that the argo project generates a schema file that all the projects can use that also includes Kubernetes native types I have a PoC here https://github.com/zachaller/argo-schema-generator this repo ideally would live under the argoproj github organization. Then each project could document and tell users how to use the generated schema's which is as simple as adding this to your kustomize file.

openapi:
  path: https://github.com/zachaller/argo-schema-generator/raw/main/schema/argo_all_k8s_kustomize_schema.json

Use Cases

Any user of Argo Projects that use kustomize would use this and find it super beneficial due to how fragile Json6902 patches are.

From the community meeting:

• Move the Argo Schema Generator to the argoproj organization
• Want to put a link in the documentation to the Argo Schema Generator once it has been moved into the argoproj organization

Do you mean argoproj-labs org instead?

[zachaller]

I think that argoproj org makes the most sense for this particular use because the links in both documentations and usage by the end users kustomization files will go to this repo.
