-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must

-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or

-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and

-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or

-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade

-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-# Descheduler for Kubernetes
-
-Scheduling in Kubernetes is the process of binding pending pods to nodes, and is performed by
-a component of Kubernetes called kube-scheduler. The scheduler's decisions, whether or where a
-pod can or can not be scheduled, are guided by its configurable policy which comprises of set of
-rules, called predicates and priorities. The scheduler's decisions are influenced by its view of
-a Kubernetes cluster at that point of time when a new pod appears for scheduling.
-As Kubernetes clusters are very dynamic and their state changes over time, there may be desire
-to move already running pods to some other nodes for various reasons:
-
-* Some nodes are under or over utilized.
-* The original scheduling decision does not hold true any more, as taints or labels are added to
-or removed from nodes, pod/node affinity requirements are not satisfied any more.
-* Some nodes failed and their pods moved to other nodes.
-* New nodes are added to clusters.
-
-Consequently, there might be several pods scheduled on less desired nodes in a cluster.
-Descheduler, based on its policy, finds pods that can be moved and evicts them. Please
-note, in current implementation, descheduler does not schedule replacement of evicted pods
-but relies on the default scheduler for that.

-## Quick Start
-
-The descheduler can be run as a Job or CronJob inside of a k8s cluster. It has the
-advantage of being able to be run multiple times without needing user intervention.
-The descheduler pod is run as a critical pod in the `kube-system` namespace to avoid
-being evicted by itself or by the kubelet.
-
-### Run As A Job

-### Install Using Helm
-
-Starting with release v0.18.0 there is an official helm chart that can be used to install the
-descheduler. See the [helm chart README](https://github.com/kubernetes-sigs/descheduler/blob/master/charts/descheduler/README.md) for detailed instructions.
-
-## User Guide
-
-See the [user guide](docs/user-guide.md) in the `/docs` directory.
-
-## Policy and Strategies
-
-Descheduler's policy is configurable and includes strategies that can be enabled or disabled.
-Seven strategies `RemoveDuplicates`, `LowNodeUtilization`, `RemovePodsViolatingInterPodAntiAffinity`,
-`RemovePodsViolatingNodeAffinity`, `RemovePodsViolatingNodeTaints`, `RemovePodsHavingTooManyRestarts`, and `PodLifeTime`
-are currently implemented. As part of the policy, the parameters associated with the strategies can be configured too.
-By default, all strategies are enabled.
-
-The policy also includes common configuration for all the strategies:
-- `nodeSelector` - limiting the nodes which are processed
-- `evictLocalStoragePods` - allowing to evict pods with local storage
-- `maxNoOfPodsToEvictPerNode` - maximum number of pods evicted from each node (summed through all strategies)
-
-```
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-nodeSelector: prod=dev
-evictLocalStoragePods: true
-maxNoOfPodsToEvictPerNode: 40
-strategies:
-  ...
-```
-
-### RemoveDuplicates
-
-This strategy makes sure that there is only one pod associated with a Replica Set (RS),
-Replication Controller (RC), Deployment, or Job running on the same node. If there are more,
-those duplicate pods are evicted for better spreading of pods in a cluster. This issue could happen
-if some nodes went down due to whatever reasons, and pods on them were moved to other nodes leading to
-more than one pod associated with a RS or RC, for example, running on the same node. Once the failed nodes
-are ready again, this strategy could be enabled to evict those duplicate pods.
-
-It provides one optional parameter, `ExcludeOwnerKinds`, which is a list of OwnerRef `Kind`s. If a pod
-has any of these `Kind`s listed as an `OwnerRef`, that pod will not be considered for eviction.
-
-```
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "RemoveDuplicates":
-     enabled: true
-     params:
-       removeDuplicates:
-         excludeOwnerKinds:
-         - "ReplicaSet"
-```
-
-### LowNodeUtilization
-
-This strategy finds nodes that are under utilized and evicts pods, if possible, from other nodes
-in the hope that recreation of evicted pods will be scheduled on these underutilized nodes. The
-parameters of this strategy are configured under `nodeResourceUtilizationThresholds`.
-
-The under utilization of nodes is determined by a configurable threshold `thresholds`. The threshold
-`thresholds` can be configured for cpu, memory, and number of pods in terms of percentage. If a node's
-usage is below threshold for all (cpu, memory, and number of pods), the node is considered underutilized.
-Currently, pods request resource requirements are considered for computing node resource utilization.
-
-There is another configurable threshold, `targetThresholds`, that is used to compute those potential nodes
-from where pods could be evicted. If a node's usage is above targetThreshold for any (cpu, memory, or number of pods),
-the node is considered over utilized. Any node between the thresholds, `thresholds` and `targetThresholds` is
-considered appropriately utilized and is not considered for eviction. The threshold, `targetThresholds`,
-can be configured for cpu, memory, and number of pods too in terms of percentage.
-
-These thresholds, `thresholds` and `targetThresholds`, could be tuned as per your cluster requirements.
-Here is an example of a policy for this strategy:
-
-```
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "LowNodeUtilization":
-     enabled: true
-     params:
-       nodeResourceUtilizationThresholds:
-         thresholds:
-           "cpu" : 20
-           "memory": 20
-           "pods": 20
-         targetThresholds:
-           "cpu" : 50
-           "memory": 50
-           "pods": 50
-```
-
-Policy should pass the following validation checks:
-* Only three types of resources are supported: `cpu`, `memory` and `pods`.
-* `thresholds` or `targetThresholds` can not be nil and they must configure exactly the same types of resources.
-* The valid range of the resource's percentage value is \[0, 100\]
-* Percentage value of `thresholds` can not be greater than `targetThresholds` for the same resource.
-
-If any of the resource types is not specified, all its thresholds default to 100% to avoid nodes going
-from underutilized to overutilized.
-
-There is another parameter associated with the `LowNodeUtilization` strategy, called `numberOfNodes`.
-This parameter can be configured to activate the strategy only when the number of under utilized nodes
-are above the configured value. This could be helpful in large clusters where a few nodes could go
-under utilized frequently or for a short period of time. By default, `numberOfNodes` is set to zero.
-
-### RemovePodsViolatingInterPodAntiAffinity
-
-This strategy makes sure that pods violating interpod anti-affinity are removed from nodes. For example,
-if there is podA on a node and podB and podC (running on the same node) have anti-affinity rules which prohibit
-them to run on the same node, then podA will be evicted from the node so that podB and podC could run. This
-issue could happen, when the anti-affinity rules for podB and podC are created when they are already running on
-node. Currently, there are no parameters associated with this strategy. To disable this strategy, the
-policy should look like:
-
-```
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "RemovePodsViolatingInterPodAntiAffinity":
-     enabled: false
-```
-
-### RemovePodsViolatingNodeAffinity
-
-This strategy makes sure all pods violating
-[node affinity](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#node-affinity)
-are eventually removed from nodes. Node affinity rules allow a pod to specify
-`requiredDuringSchedulingIgnoredDuringExecution` type, which tells the scheduler
-to respect node affinity when scheduling the pod but kubelet to ignore
-in case node changes over time and no longer respects the affinity.
-When enabled, the strategy serves as a temporary implementation
-of `requiredDuringSchedulingRequiredDuringExecution` and evicts pod for kubelet
-that no longer respects node affinity.
-
-For example, there is podA scheduled on nodeA which satisfies the node
-affinity rule `requiredDuringSchedulingIgnoredDuringExecution` at the time
-of scheduling. Over time nodeA stops to satisfy the rule. When the strategy gets
-executed and there is another node available that satisfies the node affinity rule,
-podA gets evicted from nodeA.
-
-The policy file should look like:
-
-```
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "RemovePodsViolatingNodeAffinity":
-    enabled: true
-    params:
-      nodeAffinityType:
-      - "requiredDuringSchedulingIgnoredDuringExecution"
-```
-
-### RemovePodsViolatingNodeTaints
-
-This strategy makes sure that pods violating NoSchedule taints on nodes are removed. For example there is a
-pod "podA" with a toleration to tolerate a taint ``key=value:NoSchedule`` scheduled and running on the tainted
-node. If the node's taint is subsequently updated/removed, taint is no longer satisfied by its pods' tolerations
-and will be evicted. The policy file should look like:
-
-````
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "RemovePodsViolatingNodeTaints":
-    enabled: true
-````
-
-### RemovePodsHavingTooManyRestarts
-
-This strategy makes sure that pods having too many restarts are removed from nodes. For example a pod with EBS/PD that can't get the volume/disk attached to the instance, then the pod should be re-scheduled to other nodes.
-
-```
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "RemovePodsHavingTooManyRestarts":
-     enabled: true
-     params:
-       podsHavingTooManyRestarts:
-         podRestartThreshold: 100
-         includingInitContainers: true
-```
-
-### PodLifeTime
-
-This strategy evicts pods that are older than `.strategies.PodLifeTime.params.maxPodLifeTimeSeconds` The policy
-file should look like:
-
-````
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "PodLifeTime":
-     enabled: true
-     params:
-        maxPodLifeTimeSeconds: 86400
-````
-
-## Filter Pods
-
-### Namespace filtering
-
-Strategies like `PodLifeTime`, `RemovePodsHavingTooManyRestarts`, `RemovePodsViolatingNodeTaints`,
-`RemovePodsViolatingNodeAffinity` and `RemovePodsViolatingInterPodAntiAffinity` can specify `namespaces`
-parameter which allows to specify a list of including, resp. excluding namespaces.
-E.g.
-
-```
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "PodLifeTime":
-     enabled: true
-     params:
-        maxPodLifeTimeSeconds: 86400
-        namespaces:
-          include:
-          - "namespace1"
-          - "namespace2"
-```
-
-In the examples `PodLifeTime` gets executed only over `namespace1` and `namespace2`.
-The similar holds for `exclude` field:
-
-```
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "PodLifeTime":
-     enabled: true
-     params:
-        maxPodLifeTimeSeconds: 86400
-        namespaces:
-          exclude:
-          - "namespace1"
-          - "namespace2"
-```
-
-The strategy gets executed over all namespaces but `namespace1` and `namespace2`.
-
-It's not allowed to compute `include` with `exclude` field.
-
-### Priority filtering
-
-All strategies are able to configure a priority threshold, only pods under the threshold can be evicted. You can
-specify this threshold by setting `thresholdPriorityClassName`(setting the threshold to the value of the given
-priority class) or `thresholdPriority`(directly setting the threshold) parameters. By default, this threshold
-is set to the value of `system-cluster-critical` priority class.
-E.g.
-
-Setting `thresholdPriority`
-```
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "PodLifeTime":
-     enabled: true
-     params:
-        maxPodLifeTimeSeconds: 86400
-        thresholdPriority: 10000
-```
-
-Setting `thresholdPriorityClassName`
-```
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "PodLifeTime":
-     enabled: true
-     params:
-        maxPodLifeTimeSeconds: 86400
-        thresholdPriorityClassName: "priorityclass1"
-```
-
-Note that you can't configure both `thresholdPriority` and `thresholdPriorityClassName`, if the given priority class
-does not exist, descheduler won't create it and will throw an error.
-
-## Pod Evictions
-
-When the descheduler decides to evict pods from a node, it employs the following general mechanism:
-
-* [Critical pods](https://kubernetes.io/docs/tasks/administer-cluster/guaranteed-scheduling-critical-addon-pods/) (with priorityClassName set to system-cluster-critical or system-node-critical) are never evicted.
-* Pods (static or mirrored pods or stand alone pods) not part of an RC, RS, Deployment or Job are
-never evicted because these pods won't be recreated.
-* Pods associated with DaemonSets are never evicted.
-* Pods with local storage are never evicted.
-* In `LowNodeUtilization` and `RemovePodsViolatingInterPodAntiAffinity`, pods are evicted by their priority from low to high, and if they have same priority,
-best effort pods are evicted before burstable and guaranteed pods.
-* All types of pods with the annotation descheduler.alpha.kubernetes.io/evict are evicted. This
-  annotation is used to override checks which prevent eviction and users can select which pod is evicted.
-  Users should know how and if the pod will be recreated.
-
-Setting `--v=4` or greater on the Descheduler will log all reasons why any pod is not evictable.
-
-### Pod Disruption Budget (PDB)
-
-Pods subject to a Pod Disruption Budget(PDB) are not evicted if descheduling violates its PDB. The pods
-are evicted by using the eviction subresource to handle PDB.
-
-## Compatibility Matrix
-The below compatibility matrix shows the k8s client package(client-go, apimachinery, etc) versions that descheduler
-is compiled with. At this time descheduler does not have a hard dependency to a specific k8s release. However a
-particular descheduler release is only tested against the three latest k8s minor versions. For example descheduler
-v0.18 should work with k8s v1.18, v1.17, and v1.16.
-
-Starting with descheduler release v0.18 the minor version of descheduler matches the minor version of the k8s client
-packages that it is compiled with.
-
-Descheduler  | Supported Kubernetes Version
--------------|-----------------------------
-v0.19        | v1.19
-v0.18        | v1.18
-v0.10        | v1.17
-v0.4-v0.9    | v1.9+
-v0.1-v0.3    | v1.7-v1.8

-# Descheduler for Kubernetes
-
-[Descheduler](https://github.com/kubernetes-sigs/descheduler/) for Kubernetes is used to rebalance clusters by evicting pods that can potentially be scheduled on better nodes. In the current implementation, descheduler does not schedule replacement of evicted pods but relies on the default scheduler for that.
-
-## TL;DR:
-
-```shell
-helm repo add descheduler https://kubernetes-sigs.github.io/descheduler/
-helm install --name my-release descheduler/descheduler-helm-chart
-```
-
-## Introduction
-
-This chart bootstraps a [desheduler](https://github.com/kubernetes-sigs/descheduler/) cron job on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
-
-## Prerequisites
-
-- Kubernetes 1.14+
-
-## Installing the Chart
-
-To install the chart with the release name `my-release`:
-
-```shell
-helm install --name my-release descheduler/descheduler-helm-chart
-```
-
-The command deploys _descheduler_ on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
-
-> **Tip**: List all releases using `helm list`
-
-## Uninstalling the Chart
-
-To uninstall/delete the `my-release` deployment:
-
-```shell
-helm delete my-release
-```
-
-The command removes all the Kubernetes components associated with the chart and deletes the release.
-
-## Configuration
-
-The following table lists the configurable parameters of the _descheduler_ chart and their default values.
-
-| Parameter                      | Description                                                                                                           | Default                                                |

-
-## Container Image
-
-### Semi-automatic
-
-1. Make sure your repo is clean by git's standards
-2. Create a release branch `git checkout -b release-1.18` (not required for patch releases)
-3. Push the release branch to the descheuler repo and ensure branch protection is enabled (not required for patch releases)
-4. Tag the repository from the `master` branch (from the `release-1.18` branch for a patch release) and push the tag `VERSION=v0.18.0 git tag -m $VERSION $VERSION; git push origin $VERSION`
-5. Publish a draft release using the tag you just created
-6. Perform the [image promotion process](https://github.com/kubernetes/k8s.io/tree/master/k8s.gcr.io#image-promoter)
-7. Publish release
-8. Email `kubernetes-sig-scheduling@googlegroups.com` to announce the release
-
-### Manual
-
-1. Make sure your repo is clean by git's standards
-2. Create a release branch `git checkout -b release-1.18` (not required for patch releases)
-3. Push the release branch to the descheuler repo and ensure branch protection is enabled (not required for patch releases)
-4. Tag the repository from the `master` branch (from the `release-1.18` branch for a patch release) and push the tag `VERSION=v0.18.0 git tag -m $VERSION $VERSION; git push origin $VERSION`
-5. Checkout the tag you just created and make sure your repo is clean by git's standards `git checkout $VERSION`
-6. Build and push the container image to the staging registry `VERSION=$VERSION make push`
-7. Publish a draft release using the tag you just created
-8. Perform the [image promotion process](https://github.com/kubernetes/k8s.io/tree/master/k8s.gcr.io#image-promoter)
-9. Publish release
-10. Email `kubernetes-sig-scheduling@googlegroups.com` to announce the release
-
-### Notes
-It's important to create the tag on the master branch after creating the release-* branch so that the [Helm releaser-action](#helm-chart) can work.
-It compares the changes in the action-triggering branch to the latest tag on that branch, so if you tag before creating the new branch there
-will be nothing to compare and it will fail (creating a new release branch usually involves no code changes). For this same reason, you should
-also tag patch releases (on the release-* branch) *after* pushing changes (if those changes involve bumping the Helm chart version).
-
-See [post-descheduler-push-images dashboard](https://testgrid.k8s.io/sig-scheduling#post-descheduler-push-images) for staging registry image build job status.
-
-View the descheduler staging registry using [this URL](https://console.cloud.google.com/gcr/images/k8s-staging-descheduler/GLOBAL/descheduler) in a web browser
-or use the below `gcloud` commands.
-
-List images in staging registry.
-```
-gcloud container images list --repository gcr.io/k8s-staging-descheduler
-```
-
-List descheduler image tags in the staging registry.
-```
-gcloud container images list-tags gcr.io/k8s-staging-descheduler/descheduler
-```
-
-Get SHA256 hash for a specific image in the staging registry.
-```
-gcloud container images describe gcr.io/k8s-staging-descheduler/descheduler:v20200206-0.9.0-94-ge2a23f284
-```
-
-Pull image from the staging registry.
-```
-docker pull gcr.io/k8s-staging-descheduler/descheduler:v20200206-0.9.0-94-ge2a23f284
-```
-
-## Helm Chart
-Helm chart releases are managed by a separate set of git tags that are prefixed with `descheduler-helm-chart-*`. Example git tag name is `descheduler-helm-chart-0.18.0`.
-Released versions of the helm charts are stored in the `gh-pages` branch of this repo. The [chart-releaser-action GitHub Action](https://github.com/helm/chart-releaser-action)
-is setup to build and push the helm charts to the `gh-pages` branch when changes are pushed to a `release-*` branch.
-
-The major and minor version of the chart matches the descheduler major and minor versions. For example descheduler helm chart version helm-descheduler-chart-0.18.0 corresponds
-to descheduler version v0.18.0. The patch version of the descheduler helm chart and the patcher version of the descheduler will not necessarily match. The patch
-version of the descheduler helm chart is used to version changes specific to the helm chart.
-
-1. Merge all helm chart changes into the master branch before the release is tagged/cut
-   1. Ensure that `appVersion` in file `charts/descheduler/Chart.yaml` matches the descheduler version(no `v` prefix)
-   2. Ensure that `version` in file `charts/descheduler/Chart.yaml` has been incremented. This is the chart version.
-2. Make sure your repo is clean by git's standards
-3. Follow the release-branch or patch release tagging pattern from the above section.
-4. Verify the new helm artifact has been successfully pushed to the `gh-pages` branch

-# User Guide
-
-Starting with descheduler release v0.10.0 container images are available in the official k8s container registry.
-* `k8s.gcr.io/descheduler/descheduler`
-
-## Policy Configuration Examples
-The [examples](https://github.com/kubernetes-sigs/descheduler/tree/master/examples) directory has descheduler policy configuration examples.
-
-## CLI Options
-The descheduler has many CLI options that can be used to override its default behavior.
-```
-descheduler --help
-The descheduler evicts pods which may be bound to less desired nodes
-
-Usage:
-  descheduler [flags]
-  descheduler [command]
-
-Available Commands:
-  help        Help about any command
-  version     Version of descheduler
-
-Flags:
-      --add-dir-header                   If true, adds the file directory to the header of the log messages
-      --alsologtostderr                  log to standard error as well as files
-      --descheduling-interval duration   Time interval between two consecutive descheduler executions. Setting this value instructs the descheduler to run in a continuous loop at the interval specified.
-      --dry-run                          execute descheduler in dry run mode.
-      --evict-local-storage-pods         DEPRECATED: enables evicting pods using local storage by descheduler
-  -h, --help                             help for descheduler
-      --kubeconfig string                File with  kube configuration.
-      --log-backtrace-at traceLocation   when logging hits line file:N, emit a stack trace (default :0)
-      --log-dir string                   If non-empty, write log files in this directory
-      --log-file string                  If non-empty, use this log file
-      --log-file-max-size uint           Defines the maximum size a log file can grow to. Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
-      --log-flush-frequency duration     Maximum number of seconds between log flushes (default 5s)
-      --logtostderr                      log to standard error instead of files (default true)
-      --max-pods-to-evict-per-node int   DEPRECATED: limits the maximum number of pods to be evicted per node by descheduler
-      --node-selector string             DEPRECATED: selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2)
-      --policy-config-file string        File with descheduler policy configuration.
-      --skip-headers                     If true, avoid header prefixes in the log messages
-      --skip-log-headers                 If true, avoid headers when opening log files
-      --stderrthreshold severity         logs at or above this threshold go to stderr (default 2)
-  -v, --v Level                          number for the log level verbosity
-      --vmodule moduleSpec               comma-separated list of pattern=N settings for file-filtered logging
-
-Use "descheduler [command] --help" for more information about a command.

-## Production Use Cases
-This section contains descriptions of real world production use cases.
-
-### Balance Cluster By Pod Age
-When initially migrating applications from a static virtual machine infrastructure to a cloud native k8s
-infrastructure there can be a tendency to treat application pods like static virtual machines. One approach
-to help prevent developers and operators from treating pods like virtual machines is to ensure that pods
-only run for a fixed amount
-of time.
-
-The `PodLifeTime` strategy can be used to ensure that old pods are evicted. It is recommended to create a
-[pod disruption budget](https://kubernetes.io/docs/tasks/run-application/configure-pdb/) for each
-application to ensure application availability.
-```
-descheduler -v=3 --evict-local-storage-pods --policy-config-file=pod-life-time.yml
-```
-
-This policy configuration file ensures that pods created more than 7 days ago are evicted.

-
-### Autoheal Node Problems
-Descheduler's `RemovePodsViolatingNodeTaints` strategy can be combined with
-[Node Problem Detector](https://github.com/kubernetes/node-problem-detector/) and
-[Cluster Autoscaler](https://github.com/kubernetes/autoscaler/tree/master/cluster-autoscaler) to automatically remove
-Nodes which have problems. Node Problem Detector can detect specific Node problems and taint any Nodes which have those
-problems. The Descheduler will then deschedule workloads from those Nodes. Finally, if the descheduled Node's resource
-allocation falls below the Cluster Autoscaler's scale down threshold, the Node will become a scale down candidate
-and can be removed by Cluster Autoscaler. These three components form an autohealing cycle for Node problems.
