Custom Objects

Custom objects, which are custom resource definitions not specified by the Kubernetes standard API, can be utilized and managed in kuber with the custom_v1.CustomObject resource. Any unknown resource definition encountered by Kuber will be assumed to be a custom object and loaded as a custom_v1.CustomObject.

For example, given the custom object definition below:

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  generateName: steps-
spec:
  entrypoint: hello
  templates:
  - name: hello
    steps:
    - - name: hello
        template: whalesay
        arguments:
          parameters: [{name: message, value: "hello1"}]
  - name: whalesay
    inputs:
      parameters:
      - name: message
    container:
      image: docker/whalesay
      command: [cowsay]
      args: ["{{inputs.parameters.message}}"]

this can be loaded into a CustomObject resource directly:

import pathlib
import yaml

from kuber.latest import custom_v1

workflow = typing.cast(
    custom_v1.CustomObject,
    kuber.from_yaml_file(directory.joinpath("workflow.yaml"))
)
