I'm looking into the use of Redhat Openshift Serverless operator. We have an Openshift cluster which uses resource quota's in each namespace. I've installed the operator and setup the knative-serving namespace. Knative-serving operator is set up where we have user-container, queue-proxy, and webhooks defined under the resources. Now when I start a service in another namespace using the following yaml file:

apiVersion: serving.kanative.dev/v1
kind: Service
metadata:
  name: helloworld-python
  namespace: test
spec:
  template:
    spec:
      containers:
      -image: test/helloworld-python:latest
       resources:
         limits:
           cpu: 100m
           memory: 50Mi
         requests:
           cpu: 100m
           memory: 50Mi
       env:
         - name: TARGET
           value: "Python Sample v1"

This however fails with the error: Error creating: pods is forbidden: failed quota: compute-resources: must specify limits.memory, requests.memory

Can any of you point me in the right direction to get this working?

Regards

I guess it's failing because the queue-proxy isn't getting the necessary memory settings set. You can do that globally via the Knative Serving config. The values I've chosen here are just placeholders.

apiVersion: operator.knative.dev/v1alpha1
kind: KnativeServing
metadata:
  name: knative-serving
spec:
  config:
    deployment:
      queueSidecarMemoryRequest: "100Mi"
      queueSidecarMemoryLimit: "300Mi"
