Canary OpenAPI validation fails when not specifying a HPA ref

[stefanprodan]

As per kubernetes/apiextensions-apiserver#25 CRD validation doesn't accept empty values for type "object" fields.

Workaround:

            autoscalerRef:
              anyOf:
                - type: string
                - type: object
              required: ['apiVersion', 'kind', 'name']
              properties:
                apiVersion:
                  type: string
                kind:
                  type: string
                name:
                  type: string

@carlossg thanks for finding this bug. The fix will be included in Flagger v0.3.0 that comes with Canary v1alpha3. You'll have to apply the new CRD and upgrade all your canaries definitions to v1alpha3.

I'll ping you when the release is ready, thanks again 👍

@carlossg I've just released v0.3.0 besides the CRD version being bumped to v1alpha3 there is a breaking change regarding the control loop interval. The flag controlLoopInterval has been removed from the chart and now the interval can be set in the CRD using canaryAnalysis.interval (defaults to 1m).

I've documented the change here
