[Operator] Add support for Kubernetes Functions

XMLWordPrintable

      Knative/Kubernetes resources such as KN Service, Service, Ingress, Deployment, Pods, and so on (see: https://github.com/knative/specs/blob/main/specs/eventing/overview.md#addressable) can be called by a regular HTTP POST request.

      This means that SW could support this feature out of the box, not needing an OpenAPI interface to do so.

      Image this example:

      {
  "id": "myworkflow",
  "specVersion": "0.8",
  "version": "1.0",
  "start": "State1",
  "functions": [
    {
      "name": "function1",
      "type": "custom",
      "operation": "kubernetes:serving.knative.dev/v1/mynamespace/myservice",
      "metadata": {
        "path": "/my_path"
      }
    }
  ],
  "states": [
    {
      "name": "State1",
      "type": "operation",
      "actions": [
        {
          "functionRef": {
            "refName": "function1",
            "arguments": {
              "data": "${ .data }"
            }
          }
        }
      ],
      "end": true
    }
  ]
}

      The engine would make POST requests to these endpoints with the given payload manipulated by the workflow. For example:

      kubernetes:serving.knative.dev/v1/mynamespace/myservice -> the explicitly kubernetes resource at mynamespace

      This will make the integration with the platform way easier and enhance the dev experience.

      This feature can be done based on https://issues.redhat.com/browse/KOGITO-7373.
