RE: Flink Operator Resources Requests and Limits

[PACE, JAMES]

That does not seem to work.

For instance:
  jobManager:
    podTemplate:
      spec:
        containers:
          - resources:
              requests:
                cpu: "0.5"
                memory: "2048m"
              limits:
                cpu: "2"
                memory: "2048m"

results in a pod like this:
    Limits:
      cpu:     1
      memory:  1600Mi
    Requests:
      cpu:     1
      memory:  1600Mi

This appears to be overwritten by a default if cpu and memory do not appear in 
the jobManager resources.

Hi James,

Have you considered using pod templates already?

We are currently evaluating the apache flink operator (version 1.1.0) to 
replace the operator that we currently use.  Setting the memory and cpu 
resources sets both the request and the limit for the pod.  Previously, we were 
only setting request allowing pods to oversubscribe to CPU when needed to 
handle the burstiness of the traffic that we see into the jobs.

Is there a way to set different values for cpu for resource requests and 
limits, or omit the limit specification?  If not, is this something that would 
be on the roadmap?

Thanks.
