423ee35846 Add New PodLifeTime Strategy 
The new PodLifeTime descheduler strategy can be used to evict pods that
were created more than the configured number of seconds ago.

In the below example pods created more than 24 hours ago will be evicted.

991eddb691 Turn StrategyParameters.NodeResourceUtilizationThresholds field into a pointer 
The field is intended to be omitempty when not set. Without a pointer the strategy
serialized into json string looks like:

```json
strategies:
  LowNodeUtilization:
    enabled: true
    params:
      nodeResourceUtilizationThresholds:
        numberOfNodes: 1
        targetThresholds:
          cpu: 50
          memory: 50
          pods: 20
        thresholds:
          cpu: 50
          memory: 50
          pods: 20
  RemoveDuplicates:
    enabled: true
    params:
      nodeResourceUtilizationThresholds: {}
  RemovePodsViolatingInterPodAntiAffinity:
    enabled: true
    params:
      nodeResourceUtilizationThresholds: {}
  RemovePodsViolatingNodeAffinity:
    enabled: true
    params:
      nodeAffinityType:
      - requiredDuringSchedulingIgnoredDuringExecution
      nodeResourceUtilizationThresholds: {}
  RemovePodsViolatingNodeTaints:
    enabled: true
    params:
      nodeResourceUtilizationThresholds: {}
```

It's preferred to have the following json string instead:
```
strategies:
  LowNodeUtilization:
    enabled: true
    params:
      nodeResourceUtilizationThresholds:
        numberOfNodes: 1
        targetThresholds:
          cpu: 50
          memory: 50
          pods: 20
        thresholds:
          cpu: 50
          memory: 50
          pods: 20
  RemoveDuplicates:
    enabled: true
  RemovePodsViolatingInterPodAntiAffinity:
    enabled: true
  RemovePodsViolatingNodeAffinity:
    enabled: true
    params:

  RemovePodsViolatingNodeTaints:
    enabled: true

240fa93bc5 Move maximum-pods-per-nodes-evicted logic under a single invocation 
Each strategy implements a test for checking if a maximum number of pods per node
was already evicted. The test duplicates a code that can be put
under a single invocation. Thus, reducing the number of arguments passed
to each strategy given EvicPod call can encapsulate both the check
and the invocation of the pod eviction itself.

150f945592 lownodeutilization: clasify pods of over utilized nodes only 
Only over utilized nodes need clasification of pods into categories.
Thus, skipping categorizing of pods which saves computation time in cases
where the number of over utilized nodes makes less than 50% of all nodes
or their fraction.

readme: RemovePodsViolatingNodeAffinity: reword description of the strategy
 2020-04-16 20:59:08 -07:00
Jan Chaloupka
e0c101c5ae readme: RemovePodsViolatingNodeAffinity: reword description of the strategy 
Compared to https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#node-affinity
the strategy kinda implements requiredDuringSchedulingRequiredDuringExecution node affinity type
for kubelets. Only addition to kubelet is the strategy checks whether is at least another node
capable of respecting the node affinity rules.

When requiredDuringSchedulingRequiredDuringExecution node affinity type is implemented in kubelet,
it's likely the strategy either gets removed or re-implemented. Stressing the relation with
requiredDuringSchedulingRequiredDuringExecution will helps consumers of descheduler
to keep in mind the kubelet will eventually take over the strategy when implemented.
