 # 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

 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.

 ## 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

-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.

-### 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.

-
-## Examples
-
-From `example_test.go` (note that in your code, you would import "github.com/PuerkitoBio/purell", and would prefix references to its methods and constants with "purell."):
-
-```go
-package purell
-
-import (
-  "fmt"
-  "net/url"
-)
-
-func ExampleNormalizeURLString() {
-  if normalized, err := NormalizeURLString("hTTp://someWEBsite.com:80/Amazing%3f/url/",
-    FlagLowercaseScheme|FlagLowercaseHost|FlagUppercaseEscapes); err != nil {
-    panic(err)
-  } else {
-    fmt.Print(normalized)
-  }
-  // Output: http://somewebsite.com:80/Amazing%3F/url/
-}
-
-func ExampleMustNormalizeURLString() {
-  normalized := MustNormalizeURLString("hTTpS://someWEBsite.com:443/Amazing%fa/url/",
-    FlagsUnsafeGreedy)
-  fmt.Print(normalized)
-
-  // Output: http://somewebsite.com/Amazing%FA/url
-}
-
-func ExampleNormalizeURL() {
-  if u, err := url.Parse("Http://SomeUrl.com:8080/a/b/.././c///g?c=3&a=1&b=9&c=0#target"); err != nil {
-    panic(err)
-  } else {
-    normalized := NormalizeURL(u, FlagsUsuallySafeGreedy|FlagRemoveDuplicateSlashes|FlagRemoveFragment)
-    fmt.Print(normalized)
-  }
-
-  // Output: http://someurl.com:8080/a/c/g?c=3&a=1&b=9&c=0
-}
-```
-
-## API
-
-As seen in the examples above, purell offers three methods, `NormalizeURLString(string, NormalizationFlags) (string, error)`, `MustNormalizeURLString(string, NormalizationFlags) (string)` and `NormalizeURL(*url.URL, NormalizationFlags) (string)`. They all normalize the provided URL based on the specified flags. Here are the available flags:
-
-```go
-const (

-)
-```
-
-For convenience, the set of flags `FlagsSafe`, `FlagsUsuallySafe[Greedy|NonGreedy]`, `FlagsUnsafe[Greedy|NonGreedy]` and `FlagsAll[Greedy|NonGreedy]` are provided for the similarly grouped normalizations on [wikipedia's URL normalization page][wiki]. You can add (using the bitwise OR `|` operator) or remove (using the bitwise AND NOT `&^` operator) individual flags from the sets if required, to build your own custom set.
-
-The [full godoc reference is available on gopkgdoc][godoc].
-
-Some things to note:
-
-*    `FlagDecodeUnnecessaryEscapes`, `FlagEncodeNecessaryEscapes`, `FlagUppercaseEscapes` and `FlagRemoveEmptyQuerySeparator` are always implicitly set, because internally, the URL string is parsed as an URL object, which automatically decodes unnecessary escapes, uppercases and encodes necessary ones, and removes empty query separators (an unnecessary `?` at the end of the url). So this operation cannot **not** be done. For this reason, `FlagRemoveEmptyQuerySeparator` (as well as the other three) has been included in the `FlagsSafe` convenience set, instead of `FlagsUnsafe`, where Wikipedia puts it.
-
-*    The `FlagDecodeUnnecessaryEscapes` decodes the following escapes (*from -> to*):
-    -    %24 -> $
-    -    %26 -> &
-    -    %2B-%3B -> +,-./0123456789:;
-    -    %3D -> =
-    -    %40-%5A -> @ABCDEFGHIJKLMNOPQRSTUVWXYZ
-    -    %5F -> _
-    -    %61-%7A -> abcdefghijklmnopqrstuvwxyz
-    -    %7E -> ~
-
-
-*    When the `NormalizeURL` function is used (passing an URL object), this source URL object is modified (that is, after the call, the URL object will be modified to reflect the normalization).
-
-*    The *replace IP with domain name* normalization (`http://208.77.188.166/ → http://www.example.com/`) is obviously not possible for a library without making some network requests. This is not implemented in purell.
-
-*    The *remove unused query string parameters* and *remove default query parameters* are also not implemented, since this is a very case-specific normalization, and it is quite trivial to do with an URL object.
-
-### Safe vs Usually Safe vs Unsafe
-
-Purell allows you to control the level of risk you take while normalizing an URL. You can aggressively normalize, play it totally safe, or anything in between.
-
-Consider the following URL:
-
-`HTTPS://www.RooT.com/toto/t%45%1f///a/./b/../c/?z=3&w=2&a=4&w=1#invalid`
-
-Normalizing with the `FlagsSafe` gives:
-
-`https://www.root.com/toto/tE%1F///a/./b/../c/?z=3&w=2&a=4&w=1#invalid`
-
-With the `FlagsUsuallySafeGreedy`:
-
-`https://www.root.com/toto/tE%1F///a/c?z=3&w=2&a=4&w=1#invalid`
-
-And with `FlagsUnsafeGreedy`:
-
-`http://root.com/toto/tE%1F/a/c?a=4&w=1&w=2&z=3`
-
-## TODOs
-
-*    Add a class/default instance to allow specifying custom directory index names? At the moment, removing directory index removes `(^|/)((?:default|index)\.\w{1,4})$`.

-==========
-package for building REST-style Web Services using Google Go

-
-REST asks developers to use HTTP methods explicitly and in a way that's consistent with the protocol definition. This basic REST design principle establishes a one-to-one mapping between create, read, update, and delete (CRUD) operations and HTTP methods. According to this mapping:
-
- GET = Retrieve a representation of a resource
- POST = Create if you are sending content to the server to create a subordinate of the specified resource collection, using some server-side algorithm.
- PUT = Create if you are sending the full content of the specified resource (URI).
- PUT = Update if you are updating the full content of the specified resource.
- DELETE = Delete if you are requesting the server to delete the resource
- PATCH = Update partial content of a resource
- OPTIONS = Get information about the communication options for the request URI
-    
-### Example
-
-```Go
-ws := new(restful.WebService)
-ws.
-	Path("/users").
-	Consumes(restful.MIME_XML, restful.MIME_JSON).
-	Produces(restful.MIME_JSON, restful.MIME_XML)
-
-ws.Route(ws.GET("/{user-id}").To(u.findUser).
-	Doc("get a user").
-	Param(ws.PathParameter("user-id", "identifier of the user").DataType("string")).
-	Writes(User{}))		
-...
-	
-func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
-	id := request.PathParameter("user-id")
-	...
-}
-```
-

-		
-### Features
-
- Routes for request &#8594; function mapping with path parameter (e.g. {id}) support
- Configurable router:
-	- (default) Fast routing algorithm that allows static elements, regular expressions and dynamic parameters in the URL path (e.g. /meetings/{id} or /static/{subpath:*}
-	- Routing algorithm after [JSR311](http://jsr311.java.net/nonav/releases/1.1/spec/spec.html) that is implemented using (but does **not** accept) regular expressions
- Request API for reading structs from JSON/XML and accesing parameters (path,query,header)
- Response API for writing structs to JSON/XML and setting headers
- Customizable encoding using EntityReaderWriter registration
- Filters for intercepting the request &#8594; response flow on Service or Route level
- Request-scoped variables using attributes
- Containers for WebServices on different HTTP endpoints
- Content encoding (gzip,deflate) of request and response payloads
- Automatic responses on OPTIONS (using a filter)
- Automatic CORS request handling (using a filter)
- API declaration for Swagger UI ([go-restful-openapi](https://github.com/emicklei/go-restful-openapi), see [go-restful-swagger12](https://github.com/emicklei/go-restful-swagger12))
- Panic recovery to produce HTTP 500, customizable using RecoverHandler(...)
- Route errors produce HTTP 404/405/406/415 errors, customizable using ServiceErrorHandler(...)
- Configurable (trace) logging
- Customizable gzip/deflate readers and writers using CompressorProvider registration
-
-## How to customize
-There are several hooks to customize the behavior of the go-restful package.
-
- Router algorithm
- Panic recovery
- JSON decoder
- Trace logging
- Compression
- Encoders for other serializers
- Use [jsoniter](https://github.com/json-iterator/go) by build this package using a tag, e.g. `go build -tags=jsoniter .`
-
-TODO: write examples of these.

Mike Dame	78313651dc	Update Helm release action to work on release branches Basing this action on push to `chart-*` tags doesn't work: the action itself creates the new release tag, so trying to push the changes to a tag ends up with the releaser comparing the changes to themself (and failing).
