Question

I am using flink on k8s, and now there is a problem, the dynamic resource feature of k8s cannot be utilized, one of my flink tasks only occupies a small amount of CPU resources when it runs normally, but in order for the task to start normally, it is necessary to initially set more CPUs, resulting in a lot of wasted resources, how to set mins and maxs

i am try flink on k8s native and flink operator, only support set cpu min equals max. There is no way to set them separately

Answer 1

just like this, resources limit does not work

    apiVersion: flink.apache.org/v1beta1
kind: FlinkDeployment
metadata:
  name: basic-reactive-example
spec:
  image: flink:1.17
  flinkVersion: v1_17
  serviceAccount: flink
  podTemplate:
    spec:
      containers:
        - name: flink-main-container
          resources:
            requests:
              memory: "1024Mi"
              cpu: "100m"
            limits:
              memory: "2048Mi"
              cpu: "2000m"
