# 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`, `CronJob`, or `Deployment` 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
|
||||
|
||||
```
|
||||
kubectl create -f kubernetes/base/rbac.yaml
|
||||
kubectl create -f kubernetes/base/configmap.yaml
|
||||
kubectl create -f kubernetes/job/job.yaml
|
||||
```
|
||||
|
||||
### Run As A CronJob
|
||||
|
||||
```
|
||||
kubectl create -f kubernetes/base/rbac.yaml
|
||||
kubectl create -f kubernetes/base/configmap.yaml
|
||||
kubectl create -f kubernetes/cronjob/cronjob.yaml
|
||||
```
|
||||
|
||||
### Run As A Deployment
|
||||
|
||||
```
|
||||
kubectl create -f kubernetes/base/rbac.yaml
|
||||
kubectl create -f kubernetes/base/configmap.yaml
|
||||
kubectl create -f kubernetes/deployment/deployment.yaml
|
||||
```
|
||||
|
||||
### 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.
|
||||
|
||||
The descheduler helm chart is also listed on the [artifact hub](https://artifacthub.io/packages/helm/descheduler/descheduler).
|
||||
|
||||
### Install Using Kustomize
|
||||
|
||||
You can use kustomize to install descheduler.
|
||||
See the [resources | Kustomize](https://kubectl.docs.kubernetes.io/references/kustomize/cmd/build/) for detailed instructions.
|
||||
|
||||
Run As A Job
|
||||
```
|
||||
kustomize build 'github.com/kubernetes-sigs/descheduler/kubernetes/job?ref=v0.30.1' | kubectl apply -f -
|
||||
```
|
||||
|
||||
Run As A CronJob
|
||||
```
|
||||
kustomize build 'github.com/kubernetes-sigs/descheduler/kubernetes/cronjob?ref=v0.30.1' | kubectl apply -f -
|
||||
```
|
||||
|
||||
Run As A Deployment
|
||||
```
|
||||
kustomize build 'github.com/kubernetes-sigs/descheduler/kubernetes/deployment?ref=v0.30.1' | kubectl apply -f -
|
||||
```
|
||||
|
||||
## 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. By default, all strategies are enabled.
|
||||
|
||||
The policy includes a common configuration that applies to all the strategies:
|
||||
| Name | Default Value | Description |
|
||||
|------|---------------|-------------|
|
||||
| `nodeSelector` | `nil` | limiting the nodes which are processed |
|
||||
| `evictLocalStoragePods` | `false` | allows eviction of pods with local storage |
|
||||
| `evictDaemonSetPods` | `false` | allows eviction of pods associated to DaemonSet resources |
|
||||
| `evictSystemCriticalPods` | `false` | [Warning: Will evict Kubernetes system pods] allows eviction of pods with any priority, including system pods like kube-dns |
|
||||
| `ignorePvcPods` | `false` | set whether PVC pods should be evicted or ignored |
|
||||
| `maxNoOfPodsToEvictPerNode` | `nil` | maximum number of pods evicted from each node (summed through all strategies) |
|
||||
| `maxNoOfPodsToEvictPerNamespace` | `nil` | maximum number of pods evicted from each namespace (summed through all strategies) |
|
||||
| `evictFailedBarePods` | `false` | allow eviction of pods without owner references and in failed phase |
|
||||
|
||||
As part of the policy, the parameters associated with each strategy can be configured.
|
||||
See each strategy for details on available parameters.
|
||||
|
||||
**Policy:**
|
||||
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
nodeSelector: prod=dev
|
||||
evictFailedBarePods: false
|
||||
evictLocalStoragePods: true
|
||||
evictDaemonSetPods: true
|
||||
evictSystemCriticalPods: true
|
||||
maxNoOfPodsToEvictPerNode: 40
|
||||
ignorePvcPods: false
|
||||
strategies:
|
||||
...
|
||||
```
|
||||
|
||||
The following diagram provides a visualization of most of the strategies to help
|
||||
categorize how strategies fit together.
|
||||
|
||||
|
||||
|
||||
### RemoveDuplicates
|
||||
|
||||
This strategy makes sure that there is only one pod associated with a ReplicaSet (RS),
|
||||
ReplicationController (RC), StatefulSet, 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. Note that
|
||||
pods created by Deployments are considered for eviction by this strategy. The `excludeOwnerKinds` parameter
|
||||
should include `ReplicaSet` to have pods created by Deployments excluded.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
|Name|Type|
|
||||
|---|---|
|
||||
|`excludeOwnerKinds`|list(string)|
|
||||
|`namespaces`|(see [namespace filtering](#namespace-filtering))|
|
||||
|`thresholdPriority`|int (see [priority filtering](#priority-filtering))|
|
||||
|`thresholdPriorityClassName`|string (see [priority filtering](#priority-filtering))|
|
||||
|`nodeFit`|bool (see [node fit filtering](#node-fit-filtering))|
|
||||
|
||||
**Example:**
|
||||
```yaml
|
||||
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, number of pods, and extended resources in terms of percentage (the percentage is
|
||||
calculated as the current resources requested on the node vs [total allocatable](https://kubernetes.io/docs/concepts/architecture/nodes/#capacity).
|
||||
For pods, this means the number of pods on the node as a fraction of the pod capacity set for that node).
|
||||
|
||||
If a node's usage is below threshold for all (cpu, memory, number of pods and extended resources), 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, number of pods, or extended resources),
|
||||
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. Note that this
|
||||
strategy evicts pods from `overutilized nodes` (those with usage above `targetThresholds`) to `underutilized nodes`
|
||||
(those with usage below `thresholds`), it will abort if any number of `underutilized nodes` or `overutilized nodes` is zero.
|
||||
|
||||
Additionally, the strategy accepts a `useDeviationThresholds` parameter.
|
||||
If that parameter is set to `true`, the thresholds are considered as percentage deviations from mean resource usage.
|
||||
`thresholds` will be deducted from the mean among all nodes and `targetThresholds` will be added to the mean.
|
||||
A resource consumption above (resp. below) this window is considered as overutilization (resp. underutilization).
|
||||
|
||||
**NOTE:** Node resource consumption is determined by the requests and limits of pods, not actual usage.
|
||||
This approach is chosen in order to maintain consistency with the kube-scheduler, which follows the same
|
||||
design for scheduling pods onto nodes. This means that resource usage as reported by Kubelet (or commands
|
||||
like `kubectl top`) may differ from the calculated consumption, due to these components reporting
|
||||
actual usage metrics. Implementing metrics-based descheduling is currently TODO for the project.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
|Name|Type|
|
||||
|---|---|
|
||||
|`thresholds`|map(string:int)|
|
||||
|`targetThresholds`|map(string:int)|
|
||||
|`numberOfNodes`|int|
|
||||
|`useDeviationThresholds`|bool|
|
||||
|`thresholdPriority`|int (see [priority filtering](#priority-filtering))|
|
||||
|`thresholdPriorityClassName`|string (see [priority filtering](#priority-filtering))|
|
||||
|`nodeFit`|bool (see [node fit filtering](#node-fit-filtering))|
|
||||
|`Namespaces`|(see [namespace filtering](#namespace-filtering))|
|
||||
|
||||
**Example:**
|
||||
|
||||
```yaml
|
||||
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:
|
||||
* Three basic native types of resources are supported: `cpu`, `memory` and `pods`.
|
||||
If any of these resource types is not specified, all its thresholds default to 100% to avoid nodes going from underutilized to overutilized.
|
||||
* Extended resources are supported. For example, resource type `nvidia.com/gpu` is specified for GPU node utilization. Extended resources are optional,
|
||||
and will not be used to compute node's usage if it's not specified in `thresholds` and `targetThresholds` explicitly.
|
||||
* `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.
|
||||
|
||||
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.
|
||||
|
||||
### HighNodeUtilization
|
||||
|
||||
This strategy finds nodes that are under utilized and evicts pods from the nodes in the hope that these pods will be
|
||||
scheduled compactly into fewer nodes. Used in conjunction with node auto-scaling, this strategy is intended to help
|
||||
trigger down scaling of under utilized nodes.
|
||||
This strategy **must** be used with the scheduler scoring strategy `MostAllocated`. 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, number of pods, and extended resources in terms of percentage. The percentage is
|
||||
calculated as the current resources requested on the node vs [total allocatable](https://kubernetes.io/docs/concepts/architecture/nodes/#capacity).
|
||||
For pods, this means the number of pods on the node as a fraction of the pod capacity set for that node.
|
||||
|
||||
If a node's usage is below threshold for all (cpu, memory, number of pods and extended resources), the node is considered underutilized.
|
||||
Currently, pods request resource requirements are considered for computing node resource utilization.
|
||||
Any node above `thresholds` is considered appropriately utilized and is not considered for eviction.
|
||||
|
||||
The `thresholds` param could be tuned as per your cluster requirements. Note that this
|
||||
strategy evicts pods from `underutilized nodes` (those with usage below `thresholds`)
|
||||
so that they can be recreated in appropriately utilized nodes.
|
||||
The strategy will abort if any number of `underutilized nodes` or `appropriately utilized nodes` is zero.
|
||||
|
||||
**NOTE:** Node resource consumption is determined by the requests and limits of pods, not actual usage.
|
||||
This approach is chosen in order to maintain consistency with the kube-scheduler, which follows the same
|
||||
design for scheduling pods onto nodes. This means that resource usage as reported by Kubelet (or commands
|
||||
like `kubectl top`) may differ from the calculated consumption, due to these components reporting
|
||||
actual usage metrics. Implementing metrics-based descheduling is currently TODO for the project.

|`thresholds`|map(string:int)|
|
||||
|`numberOfNodes`|int|
|

|`thresholdPriority`|int (see [priority filtering](#priority-filtering))|
|

|`thresholdPriorityClassName`|string (see [priority filtering](#priority-filtering))|
|
||||
|`nodeFit`|bool (see [node fit filtering](#node-fit-filtering))|
|
||||
|`Namespaces`|(see [namespace filtering](#namespace-filtering))|
|
||||
|
||||
**Example:**
|
||||
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
strategies:
|
||||
"HighNodeUtilization":
|
||||
enabled: true
|
||||
params:
|
||||
nodeResourceUtilizationThresholds:
|
||||
thresholds:
|
||||
"cpu" : 20
|
||||
"memory": 20
|
||||
"pods": 20
|
||||
```
|
||||
|
||||
Policy should pass the following validation checks:
|
||||
* Three basic native types of resources are supported: `cpu`, `memory` and `pods`. If any of these resource types is not specified, all its thresholds default to 100%.
|
||||
* Extended resources are supported. For example, resource type `nvidia.com/gpu` is specified for GPU node utilization. Extended resources are optional, and will not be used to compute node's usage if it's not specified in `thresholds` explicitly.
|
||||
* `thresholds` can not be nil.
|
||||
* The valid range of the resource's percentage value is \[0, 100\]
|
||||
|
||||
There is another parameter associated with the `HighNodeUtilization` strategy, called `numberOfNodes`.
|
||||
This parameter can be configured to activate the strategy only when the number of under utilized nodes
|
||||
is 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.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
|Name|Type|
|
||||
|---|---|
|
||||
|`thresholdPriority`|int (see [priority filtering](#priority-filtering))|
|
||||
|`thresholdPriorityClassName`|string (see [priority filtering](#priority-filtering))|
|
||||
|`namespaces`|(see [namespace filtering](#namespace-filtering))|
|
||||
|`labelSelector`|(see [label filtering](#label-filtering))|
|
||||
|`nodeFit`|bool (see [node fit filtering](#node-fit-filtering))|
|
||||
|
||||
**Example:**
|
||||
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
strategies:
|
||||
"RemovePodsViolatingInterPodAntiAffinity":
|
||||
enabled: true
|
||||
```
|
||||
|
||||
### 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.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
|Name|Type|
|
||||
|---|---|
|
||||
|`nodeAffinityType`|list(string)|
|
||||
|`thresholdPriority`|int (see [priority filtering](#priority-filtering))|
|
||||
|`thresholdPriorityClassName`|string (see [priority filtering](#priority-filtering))|
|
||||
|`namespaces`|(see [namespace filtering](#namespace-filtering))|
|
||||
|`labelSelector`|(see [label filtering](#label-filtering))|
|
||||
|`nodeFit`|bool (see [node fit filtering](#node-fit-filtering))|
|
||||
|
||||
**Example:**
|
||||
|
||||
```yaml
|
||||
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.
|
||||
|
||||
Node taints can be excluded from consideration by specifying a list of excludedTaints. If a node taint key **or**
|
||||
key=value matches an excludedTaints entry, the taint will be ignored.
|
||||
|
||||
For example, excludedTaints entry "dedicated" would match all taints with key "dedicated", regardless of value.
|
||||
excludedTaints entry "dedicated=special-user" would match taints with key "dedicated" and value "special-user".
|
||||
|
||||
**Parameters:**
|
||||
|
||||
|Name|Type|
|
||||
|---|---|
|
||||
|`excludedTaints`|list(string)|
|
||||
|`thresholdPriority`|int (see [priority filtering](#priority-filtering))|

|
||||
|`labelSelector`|(see [label filtering](#label-filtering))|
|
||||
|`nodeFit`|bool (see [node fit filtering](#node-fit-filtering))|
|
||||
|
||||
**Example:**
|
||||
|
||||
````yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|

excludedTaints:
|
||||
- dedicated=special-user # exclude taints with key "dedicated" and value "special-user"
|
||||
- reserved # exclude all taints with key "reserved"
|
||||
````
|
||||
|
||||
### RemovePodsViolatingTopologySpreadConstraint
|
||||
|
||||
This strategy makes sure that pods violating [topology spread constraints](https://kubernetes.io/docs/concepts/workloads/pods/pod-topology-spread-constraints/)
|
||||
are evicted from nodes. Specifically, it tries to evict the minimum number of pods required to balance topology domains to within each constraint's `maxSkew`.
|
||||
This strategy requires k8s version 1.18 at a minimum.
|
||||
|
||||
By default, this strategy only deals with hard constraints, setting parameter `includeSoftConstraints` to `true` will
|
||||
include soft constraints.
|
||||
|
||||
Strategy parameter `labelSelector` is not utilized when balancing topology domains and is only applied during eviction to determine if the pod can be evicted.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
|Name|Type|
|
||||
|---|---|
|
||||
|`includeSoftConstraints`|bool|
|
||||
|`thresholdPriority`|int (see [priority filtering](#priority-filtering))|
|
||||
|`thresholdPriorityClassName`|string (see [priority filtering](#priority-filtering))|
|
||||
|`namespaces`|(see [namespace filtering](#namespace-filtering))|
|
||||
|`labelSelector`|(see [label filtering](#label-filtering))|
|
||||
|`nodeFit`|bool (see [node fit filtering](#node-fit-filtering))|
|
||||
|
||||
**Example:**
|
||||
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
strategies:
|
||||
"RemovePodsViolatingTopologySpreadConstraint":
|
||||
enabled: true
|
||||
params:
|
||||
includeSoftConstraints: false
|
||||
```
|
||||
|
||||
|
||||
### 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. Its parameters
|
||||
include `podRestartThreshold`, which is the number of restarts (summed over all eligible containers) at which a pod
|
||||
should be evicted, and `includingInitContainers`, which determines whether init container restarts should be factored
|
||||
into that calculation.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
|Name|Type|
|
||||
|---|---|
|
||||
|`podRestartThreshold`|int|
|
||||
|`includingInitContainers`|bool|
|
||||
|`thresholdPriority`|int (see [priority filtering](#priority-filtering))|
|
||||
|`thresholdPriorityClassName`|string (see [priority filtering](#priority-filtering))|
|
||||
|`namespaces`|(see [namespace filtering](#namespace-filtering))|
|
||||
|`labelSelector`|(see [label filtering](#label-filtering))|
|
||||
|`nodeFit`|bool (see [node fit filtering](#node-fit-filtering))|
|
||||
|
||||
**Example:**
|
||||
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
strategies:
|
||||
"RemovePodsHavingTooManyRestarts":
|
||||
enabled: true
|
||||
params:
|
||||
podsHavingTooManyRestarts:
|
||||
podRestartThreshold: 100
|
||||
includingInitContainers: true
|
||||
```
|
||||
|
||||
### PodLifeTime
|
||||
|
||||
This strategy evicts pods that are older than `maxPodLifeTimeSeconds`.
|
||||
|
||||
You can also specify `states` parameter to **only** evict pods matching the following conditions:
|
||||
- [Pod Phase](https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/#pod-phase) status of: `Running`, `Pending`
|
||||
- [Container State Waiting](https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/#container-state-waiting) condition of: `PodInitializing`, `ContainerCreating`
|
||||
|
||||
If a value for `states` or `podStatusPhases` is not specified,
|
||||
Pods in any state (even `Running`) are considered for eviction.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
|Name|Type|Notes|
|
||||
|---|---|---|
|
||||
|`maxPodLifeTimeSeconds`|int||
|
||||
|`podStatusPhases`|list(string)|Deprecated in v0.25+ Use `states` instead|
|
||||
|`states`|list(string)|Only supported in v0.25+|
|
||||
|`thresholdPriority`|int (see [priority filtering](#priority-filtering))||
|
||||
|`thresholdPriorityClassName`|string (see [priority filtering](#priority-filtering))||
|
||||
|`namespaces`|(see [namespace filtering](#namespace-filtering))||
|
||||
|`labelSelector`|(see [label filtering](#label-filtering))||
|
||||
|
||||
**Example:**
|
||||
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
strategies:
|
||||
"PodLifeTime":
|
||||
enabled: true
|
||||
params:
|
||||
podLifeTime:
|
||||
maxPodLifeTimeSeconds: 86400
|
||||
states:
|
||||
- "Pending"
|
||||
- "PodInitializing"
|
||||
```
|
||||
|
||||
### RemoveFailedPods
|
||||
|
||||
This strategy evicts pods that are in failed status phase.
|
||||
You can provide an optional parameter to filter by failed `reasons`.
|
||||
`reasons` can be expanded to include reasons of InitContainers as well by setting the optional parameter `includingInitContainers` to `true`.
|
||||
You can specify an optional parameter `minPodLifetimeSeconds` to evict pods that are older than specified seconds.
|
||||
Lastly, you can specify the optional parameter `excludeOwnerKinds` and if a pod
|
||||
has any of these `Kind`s listed as an `OwnerRef`, that pod will not be considered for eviction.
|
||||
|
||||
**Parameters:**
|
||||
|
||||
|Name|Type|
|
||||
|---|---|
|
||||
|`minPodLifetimeSeconds`|uint|
|
||||
|`excludeOwnerKinds`|list(string)|
|
||||
|`reasons`|list(string)|
|
||||
|`includingInitContainers`|bool|
|
||||
|`thresholdPriority`|int (see [priority filtering](#priority-filtering))|
|
||||
|`thresholdPriorityClassName`|string (see [priority filtering](#priority-filtering))|
|
||||
|`namespaces`|(see [namespace filtering](#namespace-filtering))|
|
||||
|`labelSelector`|(see [label filtering](#label-filtering))|
|
||||
|`nodeFit`|bool (see [node fit filtering](#node-fit-filtering))|
|
||||
|
||||
**Example:**
|
||||
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
strategies:
|
||||
"RemoveFailedPods":
|
||||
enabled: true
|
||||
params:
|
||||
failedPods:
|
||||
reasons:
|
||||
- "NodeAffinity"
|
||||
includingInitContainers: true
|
||||
excludeOwnerKinds:
|
||||
- "Job"
|
||||
minPodLifetimeSeconds: 3600
|
||||
```
|
||||
|
||||
## Filter Pods
|
||||
|
||||
### Namespace filtering
|
||||
|
||||
The following strategies accept a `namespaces` parameter which allows to specify a list of including, resp. excluding namespaces:
|
||||
* `PodLifeTime`
|
||||
* `RemovePodsHavingTooManyRestarts`
|
||||
* `RemovePodsViolatingNodeTaints`
|
||||
* `RemovePodsViolatingNodeAffinity`
|
||||
* `RemovePodsViolatingInterPodAntiAffinity`
|
||||
* `RemoveDuplicates`
|
||||
* `RemovePodsViolatingTopologySpreadConstraint`
|
||||
* `RemoveFailedPods`
|
||||
* `LowNodeUtilization` and `HighNodeUtilization` (Only filtered right before eviction)
|
||||
|
||||
For example:
|
||||
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
strategies:
|
||||
"PodLifeTime":
|
||||
enabled: true
|
||||
params:
|
||||
podLifeTime:
|
||||
maxPodLifeTimeSeconds: 86400
|
||||
namespaces:
|
||||
include:
|
||||
- "namespace1"
|
||||
- "namespace2"
|
||||
```
|
||||
|
||||
In the examples `PodLifeTime` gets executed only over `namespace1` and `namespace2`.
|
||||
The similar holds for `exclude` field:
|
||||
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
strategies:
|
||||
"PodLifeTime":
|
||||
enabled: true
|
||||
params:
|
||||
podLifeTime:
|
||||
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.
|
||||
|
||||
Note: Setting `evictSystemCriticalPods` to true disables priority filtering entirely.
|
||||
|
||||
E.g.
|
||||
|
||||
Setting `thresholdPriority`
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
strategies:
|
||||
"PodLifeTime":
|
||||
enabled: true
|
||||
params:
|
||||
podLifeTime:
|
||||
maxPodLifeTimeSeconds: 86400
|
||||
thresholdPriority: 10000
|
||||
```
|
||||
|
||||
Setting `thresholdPriorityClassName`
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
strategies:
|
||||
"PodLifeTime":
|
||||
enabled: true
|
||||
params:
|
||||
podLifeTime:
|
||||
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.
|
||||
|
||||
### Label filtering
|
||||
|
||||
The following strategies can configure a [standard kubernetes labelSelector](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.26/#labelselector-v1-meta)
|
||||
to filter pods by their labels:
|
||||
|
||||
* `PodLifeTime`
|
||||
* `RemovePodsHavingTooManyRestarts`
|
||||
* `RemovePodsViolatingNodeTaints`
|
||||
* `RemovePodsViolatingNodeAffinity`
|
||||
* `RemovePodsViolatingInterPodAntiAffinity`
|
||||
* `RemovePodsViolatingTopologySpreadConstraint`
|
||||
* `RemoveFailedPods`
|
||||
|
||||
This allows running strategies among pods the descheduler is interested in.
|
||||
|
||||
For example:
|
||||
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
strategies:
|
||||
"PodLifeTime":
|
||||
enabled: true
|
||||
params:
|
||||
podLifeTime:
|
||||
maxPodLifeTimeSeconds: 86400
|
||||
labelSelector:
|
||||
matchLabels:
|
||||
component: redis
|
||||
matchExpressions:
|
||||
- {key: tier, operator: In, values: [cache]}
|
||||
- {key: environment, operator: NotIn, values: [dev]}
|
||||
```
|
||||
|
||||
|
||||
### Node Fit filtering
|
||||
|
||||
The following strategies accept a `nodeFit` boolean parameter which can optimize descheduling:
|
||||
* `RemoveDuplicates`
|
||||
* `LowNodeUtilization`
|
||||
* `HighNodeUtilization`
|
||||
* `RemovePodsViolatingInterPodAntiAffinity`
|
||||
* `RemovePodsViolatingNodeAffinity`
|
||||
* `RemovePodsViolatingNodeTaints`
|
||||
* `RemovePodsViolatingTopologySpreadConstraint`
|
||||
* `RemovePodsHavingTooManyRestarts`
|
||||
* `RemoveFailedPods`
|
||||
|
||||
If set to `true` the descheduler will consider whether or not the pods that meet eviction criteria will fit on other nodes before evicting them. If a pod cannot be rescheduled to another node, it will not be evicted. Currently the following criteria are considered when setting `nodeFit` to `true`:
|
||||
- A `nodeSelector` on the pod
|
||||
- Any `tolerations` on the pod and any `taints` on the other nodes
|
||||
- `nodeAffinity` on the pod
|
||||
- Resource `requests` made by the pod and the resources available on other nodes
|
||||
- Whether any of the other nodes are marked as `unschedulable`
|
||||
|
||||
E.g.
|
||||
|
||||
```yaml
|
||||
apiVersion: "descheduler/v1alpha1"
|
||||
kind: "DeschedulerPolicy"
|
||||
strategies:
|
||||
"LowNodeUtilization":
|
||||
enabled: true
|
||||
params:
|
||||
nodeFit: true
|
||||
nodeResourceUtilizationThresholds:
|
||||
thresholds:
|
||||
"cpu": 20
|
||||
"memory": 20
|
||||
"pods": 20
|
||||
targetThresholds:
|
||||
"cpu": 50
|
||||
"memory": 50
|
||||
"pods": 50
|
||||
```
|
||||
|
||||
Note that node fit filtering references the current pod spec, and not that of it's owner.
|
||||
Thus, if the pod is owned by a ReplicationController (and that ReplicationController was modified recently),
|
||||
the pod may be running with an outdated spec, which the descheduler will reference when determining node fit.
|
||||
This is expected behavior as the descheduler is a "best-effort" mechanism.
|
||||
|
||||
Using Deployments instead of ReplicationControllers provides an automated rollout of pod spec changes, therefore ensuring that the descheduler has an up-to-date view of the cluster state.
