-# Descheduler for Kubernetes
-
-## Introduction
-
-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 first time for scheduling.
-As Kubernetes clusters are very dynamic and their state change over time, there may be desired
-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.
-
-## Build and Run
-
-- Checkout the repo into your $GOPATH directory under src/sigs.k8s.io/descheduler
-
-Build descheduler:
-
-```sh
-$ make
-```
-
-and run descheduler:
-
-```sh
-$ ./_output/bin/descheduler --kubeconfig <path to kubeconfig> --policy-config-file <path-to-policy-file>
-```
-
-If you want more information about what descheduler is doing add `-v 1` to the command line
-
-For more information about available options run:
-```
-$ ./_output/bin/descheduler --help
-```
-
-## Running Descheduler as a Job or CronJob
-
-The descheduler can be run as a job or cronjob inside of a pod. 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 to avoid being evicted by itself,
-or by the kubelet due to an eviction event. Since critical pods are created in the
-`kube-system` namespace, the descheduler job and its pod will also be created
-in `kube-system` namespace.
-
-### Setup RBAC
-
-To give necessary permissions for the descheduler to work in a pod.
-
-```
-$ kubectl create -f kubernetes/rbac.yaml
-```
-
-### Create a configmap to store descheduler policy
-
-```
-$ kubectl create -f kubernetes/configmap.yaml
-```
-
-### Create a Job or CronJob
-
-As a Job.
-```
-$ kubectl create -f kubernetes/job.yaml
-```
-
-Or as a CronJob.
-```
-$ kubectl create -f kubernetes/cronjob.yaml
-```
-
-## Policy and Strategies
-
-Descheduler's policy is configurable and includes strategies to be enabled or disabled.
-Five strategies, `RemoveDuplicates`, `LowNodeUtilization`, `RemovePodsViolatingInterPodAntiAffinity`, `RemovePodsViolatingNodeAffinity` , `RemovePodsViolatingNodeTaints` are currently implemented.
-As part of the policy, the parameters associated with the strategies can be configured too.
-By default, all strategies are enabled.
-
-### 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 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 RS or RC, for example, running on same node. Once the failed nodes
-are ready again, this strategy could be enabled to evict those duplicate pods. Currently, there are no
-parameters associated with this strategy. To disable this strategy, the policy should look like:
-
-```
-apiVersion: "descheduler/v1alpha1"
-kind: "DeschedulerPolicy"
-strategies:
-  "RemoveDuplicates":
-     enabled: false
-```
-
-### 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. 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.
-An example of the policy for this strategy would look like:
-
-```
-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
-```
-
-There is another parameter associated with `LowNodeUtilization` strategy, called `numberOfNodes`.
-This parameter can be configured to activate the strategy only when 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 node and podB and podC(running on same node) have antiaffinity 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 pods B,C 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 that pods violating node affinity are removed from nodes. For example, there is podA that was scheduled on nodeA which satisfied the node affinity rule `requiredDuringSchedulingIgnoredDuringExecution` at the time of scheduling, but over time nodeA no longer satisfies the rule, then if another node nodeB is available that satisfies the node affinity rule, then podA will be evicted from nodeA. The policy file should like this -
-
-```
-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 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
-````
-## Pod Evictions
-
-When the descheduler decides to evict pods from a node, it employs 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 Jobs are
-never evicted because these pods won't be recreated.
-* Pods associated with DaemonSets are never evicted.
-* Pods with local storage are never evicted.
-* Best efforts pods are evicted before Burstable and Guaranteed pods.
-* All types of pods with annotation descheduler.alpha.kubernetes.io/evict are evicted. This 
-annotation is used to override checks which prevent eviction and user can select which pod is evicted. 
-User should know how and if the pod will be recreated.
-
-### Pod disruption Budget (PDB)
-Pods subject to Pod Disruption Budget (PDB) are not evicted if descheduling violates its pod
-disruption budget (PDB). The pods are evicted by using eviction subresource to handle PDB.
-
-## Roadmap
-
-This roadmap is not in any particular order.
-
-* Consideration of pod affinity
-* Strategy to consider pod life time
-* Strategy to consider number of pending pods
-* Integration with cluster autoscaler
-* Integration with metrics providers for obtaining real load metrics
-* Consideration of Kubernetes's scheduler's predicates
-

-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.

-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You

-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          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
-          include a readable copy of the attribution notices contained
-          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
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          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
-      for any such Derivative Works as a whole, provided Your use,
-      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
-      names, trademarks, service marks, or product names of the Licensor,
-      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.

-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and

-      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.

-      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.

-# Azure Active Directory authentication for Go
-
-This is a standalone package for authenticating with Azure Active
-Directory from other Go libraries and applications, in particular the [Azure SDK
-for Go](https://github.com/Azure/azure-sdk-for-go).
-
-Note: Despite the package's name it is not related to other "ADAL" libraries
-maintained in the [github.com/AzureAD](https://github.com/AzureAD) org. Issues
-should be opened in [this repo's](https://github.com/Azure/go-autorest/issues)
-or [the SDK's](https://github.com/Azure/azure-sdk-for-go/issues) issue
-trackers.
-
-## Install
-
-```bash
-go get -u github.com/Azure/go-autorest/autorest/adal
-```
-
-## Usage
-
-An Active Directory application is required in order to use this library. An application can be registered in the [Azure Portal](https://portal.azure.com/) by following these [guidelines](https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-integrating-applications) or using the [Azure CLI](https://github.com/Azure/azure-cli).
-
-### Register an Azure AD Application with secret
-
-
-1. Register a new application with a `secret` credential
-
-   ```
-   az ad app create \
-      --display-name example-app \
-      --homepage https://example-app/home \
-      --identifier-uris https://example-app/app \
-      --password secret
-   ```
-
-2. Create a service principal using the `Application ID` from previous step
-
-   ```
-   az ad sp create --id "Application ID"
-   ```
-
-   * Replace `Application ID` with `appId` from step 1.
-
-### Register an Azure AD Application with certificate
-
-1. Create a private key
-
-   ```
-   openssl genrsa -out "example-app.key" 2048
-   ```
-
-2. Create the certificate
-
-   ```
-   openssl req -new -key "example-app.key" -subj "/CN=example-app" -out "example-app.csr"
-   openssl x509 -req -in "example-app.csr" -signkey "example-app.key" -out "example-app.crt" -days 10000
-   ```
-
-3. Create the PKCS12 version of the certificate containing also the private key
-
-   ```
-   openssl pkcs12 -export -out "example-app.pfx" -inkey "example-app.key" -in "example-app.crt" -passout pass:
-
-   ```
-
-4. Register a new application with the certificate content form `example-app.crt`
-
-   ```
-   certificateContents="$(tail -n+2 "example-app.crt" | head -n-1)"
-
-   az ad app create \
-      --display-name example-app \
-      --homepage https://example-app/home \
-      --identifier-uris https://example-app/app \
-      --key-usage Verify --end-date 2018-01-01 \
-      --key-value "${certificateContents}"
-   ```
-
-5. Create a service principal using the `Application ID` from previous step
-
-   ```
-   az ad sp create --id "APPLICATION_ID"
-   ```
-
-   * Replace `APPLICATION_ID` with `appId` from step 4.
-
-
-### Grant the necessary permissions
-
-Azure relies on a Role-Based Access Control (RBAC) model to manage the access to resources at a fine-grained
-level. There is a set of [pre-defined roles](https://docs.microsoft.com/en-us/azure/active-directory/role-based-access-built-in-roles)
-which can be assigned to a service principal of an Azure AD application depending of your needs.
-
-```
-az role assignment create --assigner "SERVICE_PRINCIPAL_ID" --role "ROLE_NAME"
-```
-
-* Replace the `SERVICE_PRINCIPAL_ID` with the `appId` from previous step.
-* Replace the `ROLE_NAME` with a role name of your choice.
-
-It is also possible to define custom role definitions.
-
-```
-az role definition create --role-definition role-definition.json
-```
-
-* Check [custom roles](https://docs.microsoft.com/en-us/azure/active-directory/role-based-access-control-custom-roles) for more details regarding the content of `role-definition.json` file.
-
-
-### Acquire Access Token
-
-The common configuration used by all flows:
-
-```Go
-const activeDirectoryEndpoint = "https://login.microsoftonline.com/"
-tenantID := "TENANT_ID"
-oauthConfig, err := adal.NewOAuthConfig(activeDirectoryEndpoint, tenantID)
-
-applicationID := "APPLICATION_ID"
-
-callback := func(token adal.Token) error {
-    // This is called after the token is acquired
-}
-
-// The resource for which the token is acquired
-resource := "https://management.core.windows.net/"
-```
-
-* Replace the `TENANT_ID` with your tenant ID.
-* Replace the `APPLICATION_ID` with the value from previous section.
-
-#### Client Credentials
-
-```Go
-applicationSecret := "APPLICATION_SECRET"
-
-spt, err := adal.NewServicePrincipalToken(
-	*oauthConfig,
-	appliationID,
-	applicationSecret,
-	resource,
-	callbacks...)
-if err != nil {
-	return nil, err
-}
-
-// Acquire a new access token
-err  = spt.Refresh()
-if (err == nil) {
-    token := spt.Token
-}
-```
-
-* Replace the `APPLICATION_SECRET` with the `password` value from previous section.
-
-#### Client Certificate
-
-```Go
-certificatePath := "./example-app.pfx"
-
-certData, err := ioutil.ReadFile(certificatePath)
-if err != nil {
-	return nil, fmt.Errorf("failed to read the certificate file (%s): %v", certificatePath, err)
-}
-
-// Get the certificate and private key from pfx file
-certificate, rsaPrivateKey, err := decodePkcs12(certData, "")
-if err != nil {
-	return nil, fmt.Errorf("failed to decode pkcs12 certificate while creating spt: %v", err)
-}
-
-spt, err := adal.NewServicePrincipalTokenFromCertificate(
-	*oauthConfig,
-	applicationID,
-	certificate,
-	rsaPrivateKey,
-	resource,
-	callbacks...)
-
-// Acquire a new access token
-err  = spt.Refresh()
-if (err == nil) {
-    token := spt.Token
-}
-```
-
-* Update the certificate path to point to the example-app.pfx file which was created in previous section.
-
-
-#### Device Code
-
-```Go
-oauthClient := &http.Client{}
-
-// Acquire the device code
-deviceCode, err := adal.InitiateDeviceAuth(
-	oauthClient,
-	*oauthConfig,
-	applicationID,
-	resource)
-if err != nil {
-	return nil, fmt.Errorf("Failed to start device auth flow: %s", err)
-}
-
-// Display the authentication message
-fmt.Println(*deviceCode.Message)
-
-// Wait here until the user is authenticated
-token, err := adal.WaitForUserCompletion(oauthClient, deviceCode)
-if err != nil {
-	return nil, fmt.Errorf("Failed to finish device auth flow: %s", err)
-}
-
-spt, err := adal.NewServicePrincipalTokenFromManualToken(
-	*oauthConfig,
-	applicationID,
-	resource,
-	*token,
-	callbacks...)
-
-if (err == nil) {
-    token := spt.Token
-}
-```
-
-#### Username password authenticate
-
-```Go
-spt, err := adal.NewServicePrincipalTokenFromUsernamePassword(
-	*oauthConfig,
-	applicationID,
-	username,
-	password,
-	resource,
-	callbacks...)
-
-if (err == nil) {
-    token := spt.Token
-}
-```
-
-#### Authorization code authenticate
-
-``` Go
-spt, err := adal.NewServicePrincipalTokenFromAuthorizationCode(
-	*oauthConfig,
-	applicationID,
-	clientSecret,
-        authorizationCode,
-        redirectURI,
-	resource,
-	callbacks...)
-
-err  = spt.Refresh()
-if (err == nil) {
-    token := spt.Token
-}
-```
-
-### Command Line Tool
-
-A command line tool is available in `cmd/adal.go` that can acquire a token for a given resource. It supports all flows mentioned above.
-
-```
-adal -h
-
-Usage of ./adal:
-  -applicationId string
-        application id
-  -certificatePath string
-        path to pk12/PFC application certificate
-  -mode string
-        authentication mode (device, secret, cert, refresh) (default "device")
-  -resource string
-        resource for which the token is requested
-  -secret string
-        application secret
-  -tenantId string
-        tenant id
-  -tokenCachePath string
-        location of oath token cache (default "/home/cgc/.adal/accessToken.json")
-```
-
-Example acquire a token for `https://management.core.windows.net/` using device code flow:
-
-```
-adal -mode device \
-    -applicationId "APPLICATION_ID" \
-    -tenantId "TENANT_ID" \
-    -resource https://management.core.windows.net/
-
-```
