+The descheduler pod is run as a critical pod to avoid being evicted by itself,

-###  Create a container image
+### Setup RBAC
 
-First we create a simple Docker image utilizing the Dockerfile found in the root directory:
+To give necessary permissions for the descheduler to work in a pod.
 
 ```
-$ make dev-image
+$ kubectl create -f kubernetes/rbac.yaml
 ```
 
-This creates an image based off the binary we've built before. To build both the
-binary and image in one step you can run the following command:
-
-```
-$ make image
-```
-
-This eliminates the need to have Go installed locally and builds the binary
-within it's own container.
-
-### Create a cluster role
-
-To give necessary permissions for the descheduler to work in a pod, create a cluster role:
-
-```
-$ cat << EOF| kubectl create -f -
-kind: ClusterRole
-apiVersion: rbac.authorization.k8s.io/v1beta1
-metadata:
-  name: descheduler-cluster-role
-rules:
-- apiGroups: [""]
-  resources: ["nodes"]
-  verbs: ["get", "watch", "list"]
-- apiGroups: [""]
-  resources: ["pods"]
-  verbs: ["get", "watch", "list", "delete"]
-- apiGroups: [""]
-  resources: ["pods/eviction"]
-  verbs: ["create"]
-EOF
-```
-
-### Create the service account which will be used to run the job:
-
-```
-$ kubectl create sa descheduler-sa -n kube-system
-```
-
-### Bind the cluster role to the service account:
-
-```
-$ kubectl create clusterrolebinding descheduler-cluster-role-binding \
-    --clusterrole=descheduler-cluster-role \
-    --serviceaccount=kube-system:descheduler-sa
-```
 ### Create a configmap to store descheduler policy
 
-Descheduler policy is created as a ConfigMap in `kube-system` namespace
-so that it can be mounted as a volume inside pod.
-
 ```
-$ kubectl create configmap descheduler-policy-configmap \
-     -n kube-system --from-file=<path-to-policy-dir/policy.yaml>

+### 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:

 ## Pod Evictions
 
 When the descheduler decides to evict pods from a node, it employs following general mechanism:
 
-* Critical pods (with annotations scheduler.alpha.kubernetes.io/critical-pod) are never evicted.
+* [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.

-
-## Integration Tests
-
-In addition to the unit tests, you may run the integration test suite.
-
-To run the integrations tests, creating and configuration of a project in the
-Google Developers Console is required.
-
-After creating a project, you must [create a service account](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#creatinganaccount).
-Ensure the project-level **Owner** [IAM role](console.cloud.google.com/iam-admin/iam/project)
-(or **Editor** and **Logs Configuration Writer** roles) are added to the
-service account.
-
-Once you create a project, set the following environment variables to be able to
-run the against the actual APIs.
-
-- **GCLOUD_TESTS_GOLANG_PROJECT_ID**: Developers Console project's ID (e.g. bamboo-shift-455)
-- **GCLOUD_TESTS_GOLANG_KEY**: The path to the JSON key file.
-
-Install the [gcloud command-line tool][gcloudcli] to your machine and use it
-to create the indexes used in the datastore integration tests with indexes
-found in `datastore/testdata/index.yaml`:
-
-From the project's root directory:
-
-``` sh
-# Set the default project in your env
-$ gcloud config set project $GCLOUD_TESTS_GOLANG_PROJECT_ID
-
-# Authenticate the gcloud tool with your account
-$ gcloud auth login
-
-# Create the indexes
-$ gcloud preview datastore create-indexes datastore/testdata/index.yaml
-```
-
-The Sink integration tests in preview/logging require a Google Cloud storage
-bucket with the same name as your test project, and with the Stackdriver Logging
-service account as owner:
-``` sh
-$ gsutil mb gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID
-$ gsutil acl ch -g cloud-logs@google.com:O gs://$GCLOUD_TESTS_GOLANG_PROJECT_ID
-```
-
-Once you've set the environment variables, you can run the integration tests by
-running:
-
-``` sh
-$ go test -v cloud.google.com/go/...
-```

-## News
-
-_September 8, 2016_
-
-* New clients for some of Google's Machine Learning APIs: Vision, Speech, and
-Natural Language.
-
-* Preview version of a new [Stackdriver Logging][cloud-logging] client in
-[`cloud.google.com/go/preview/logging`](https://godoc.org/cloud.google.com/go/preview/logging).
-This client uses gRPC as its transport layer, and supports log reading, sinks
-and metrics. It will replace the current client at `cloud.google.com/go/logging` shortly.

-> **Experimental status**: the API is still being actively developed. As a
-> result, it might change in backward-incompatible ways and is not recommended
-> for production use.
->
-> **Beta status**: the API is largely complete, but still has outstanding
-> features and bugs to be addressed. There may be minor backwards-incompatible
-> changes where necessary.
->
-> **Stable status**: the API is mature and ready for production use. We will
-> continue addressing bugs and feature requests.
-
-Documentation and examples are available at
-https://godoc.org/cloud.google.com/go
-
-Visit or join the
-[google-api-go-announce group](https://groups.google.com/forum/#!forum/google-api-go-announce)
-for updates on these packages.
-
-## Go Versions Supported
-
-We support the two most recent major versions of Go. If Google App Engine uses
-an older version, we support that as well. You can see which versions are
-currently supported by looking at the lines following `go:` in
-[`.travis.yml`](.travis.yml).
-
-## Authorization
-
-By default, each API will use [Google Application Default Credentials][default-creds]
-for authorization credentials used in calling the API endpoints. This will allow your
-application to run in many environments without requiring explicit configuration.
-
-Manually-configured authorization can be achieved using the
-[`golang.org/x/oauth2`](https://godoc.org/golang.org/x/oauth2) package to
-create an `oauth2.TokenSource`. This token source can be passed to the `NewClient`
-function for the relevant API using a
-[`option.WithTokenSource`](https://godoc.org/google.golang.org/api/option#WithTokenSource)
-option.

-## Google Cloud Datastore [![GoDoc](https://godoc.org/cloud.google.com/go/datastore?status.svg)](https://godoc.org/cloud.google.com/go/datastore)
-
-[Google Cloud Datastore][cloud-datastore] ([docs][cloud-datastore-docs]) is a fully-
-managed, schemaless database for storing non-relational data. Cloud Datastore
-automatically scales with your users and supports ACID transactions, high availability
-of reads and writes, strong consistency for reads and ancestor queries, and eventual
-consistency for all other queries.
-
-Follow the [activation instructions][cloud-datastore-activation] to use the Google
-Cloud Datastore API with your project.
-
-First create a `datastore.Client` to use throughout your application:
-
-```go
-client, err := datastore.NewClient(ctx, "my-project-id")
-if err != nil {
-	log.Fatalln(err)
-}
-```
-
-Then use that client to interact with the API:
-
-```go
-type Post struct {
-	Title       string
-	Body        string `datastore:",noindex"`
-	PublishedAt time.Time
-}
-keys := []*datastore.Key{
-	datastore.NewKey(ctx, "Post", "post1", 0, nil),
-	datastore.NewKey(ctx, "Post", "post2", 0, nil),
-}
-posts := []*Post{
-	{Title: "Post 1", Body: "...", PublishedAt: time.Now()},
-	{Title: "Post 2", Body: "...", PublishedAt: time.Now()},
-}
-if _, err := client.PutMulti(ctx, keys, posts); err != nil {
-	log.Fatal(err)
-}
-```
-
-## Google Cloud Storage [![GoDoc](https://godoc.org/cloud.google.com/go/storage?status.svg)](https://godoc.org/cloud.google.com/go/storage)
-
-[Google Cloud Storage][cloud-storage] ([docs][cloud-storage-docs]) allows you to store
-data on Google infrastructure with very high reliability, performance and availability,
-and can be used to distribute large data objects to users via direct download.
-
-https://godoc.org/cloud.google.com/go/storage
-
-First create a `storage.Client` to use throughout your application:
-
-```go
-client, err := storage.NewClient(ctx)
-if err != nil {
-	log.Fatal(err)
-}
-```
-
-```go
-// Read the object1 from bucket.
-rc, err := client.Bucket("bucket").Object("object1").NewReader(ctx)
-if err != nil {
-	log.Fatal(err)
-}
-defer rc.Close()
-body, err := ioutil.ReadAll(rc)
-if err != nil {
-	log.Fatal(err)
-}
-```
-
-## Google Cloud Pub/Sub [![GoDoc](https://godoc.org/cloud.google.com/go/pubsub?status.svg)](https://godoc.org/cloud.google.com/go/pubsub)
-
-[Google Cloud Pub/Sub][cloud-pubsub] ([docs][cloud-pubsub-docs]) allows you to connect
-your services with reliable, many-to-many, asynchronous messaging hosted on Google's
-infrastructure. Cloud Pub/Sub automatically scales as you need it and provides a foundation
-for building your own robust, global services.
-
-First create a `pubsub.Client` to use throughout your application:
-
-```go
-client, err := pubsub.NewClient(ctx, "project-id")
-if err != nil {
-	log.Fatal(err)
-}
-```
-
-```go
-// Publish "hello world" on topic1.
-topic := client.Topic("topic1")
-msgIDs, err := topic.Publish(ctx, &pubsub.Message{
-	Data: []byte("hello world"),
-})
-if err != nil {
-	log.Fatal(err)
-}
-
-// Create an iterator to pull messages via subscription1.
-it, err := client.Subscription("subscription1").Pull(ctx)
-if err != nil {
-	log.Println(err)
-}
-defer it.Stop()
-
-// Consume N messages from the iterator.
-for i := 0; i < N; i++ {
-	msg, err := it.Next()
-	if err == pubsub.Done {
-		break
-	}
-	if err != nil {
-		log.Fatalf("Failed to retrieve message: %v", err)
-	}
-
-	fmt.Printf("Message %d: %s\n", i, msg.Data)
-	msg.Done(true) // Acknowledge that we've consumed the message.
-}
