Jan Chaloupka e40fab430c Move kind setup to e2e script 
This moves the kind setup (previously used by Travis) to the e2e runner script
to accomodate the switch to Prow. This provides a KIND_E2E env var to specify
whether to run the tests in kind, or (by default) to run locally).

each descheduler minor release. The release guide has been updated with
the steps to create release branches.

with the real eviction.

Mike Dame c6ff87dbd6 Consider pod image in duplicates strategy 
This increases the specificity of the RemoveDuplicates strategy by
removing pods which not only have the same owner, but who also
must have the same list of container images. This also adds a
parameter, `ExcludeOwnerKinds` to the RemoveDuplicates strategy
which accepts a list of Kinds. If a pod has any of these Kinds as
an owner, that pod is not considered for eviction.

Sean Malloy 7039b6c8aa Refactor function EvictPod to only return an error 
The EvictPod function previously returned a bool and an error. The
function now only returns an error. Callers can check for failure by
testing if the returned error is not nil. This aligns the EvictPod
function with idiomatic Go best practices.

Also, the function name has been changed from EvictPod to evictPod
because it is not used outside the evictions package.

Sean Malloy cff984261e Log an error when EvictPod method returns a non-nil error 
End users should be able to see the detailed error from the EvictPod
method when it fails. Updates all strategies to log the error. The
PodLifeTime strategy already logs this error.

Sean Malloy 4819ab9c69 Add namespace to pod eviction log messages 
In multi-tenant environments it is useful to know which namespace a pod
was evicted from. Therefore log the namespace when evicting pods.

Also, do not log a nil error when successfully evicting pods.

The new PodLifeTime descheduler strategy can be used to evict pods that
were created more than the configured number of seconds ago.

In the below example pods created more than 24 hours ago will be evicted.

Turn StrategyParameters.NodeResourceUtilizationThresholds field into a pointer
 2020-04-28 06:48:07 -07:00
Jan Chaloupka 991eddb691 Turn StrategyParameters.NodeResourceUtilizationThresholds field into a pointer 
The field is intended to be omitempty when not set. Without a pointer the strategy
serialized into json string looks like:

```json
strategies:
  LowNodeUtilization:
    enabled: true
    params:
      nodeResourceUtilizationThresholds:
        numberOfNodes: 1
        targetThresholds:
          cpu: 50
          memory: 50
          pods: 20
        thresholds:
          cpu: 50
          memory: 50
          pods: 20
  RemoveDuplicates:
    enabled: true
    params:
      nodeResourceUtilizationThresholds: {}
  RemovePodsViolatingInterPodAntiAffinity:
    enabled: true
    params:
      nodeResourceUtilizationThresholds: {}
  RemovePodsViolatingNodeAffinity:
    enabled: true
    params:
      nodeAffinityType:
      - requiredDuringSchedulingIgnoredDuringExecution
      nodeResourceUtilizationThresholds: {}
  RemovePodsViolatingNodeTaints:
    enabled: true
    params:
      nodeResourceUtilizationThresholds: {}
```

It's preferred to have the following json string instead:
```
strategies:
  LowNodeUtilization:
    enabled: true
    params:
      nodeResourceUtilizationThresholds:
        numberOfNodes: 1
        targetThresholds:
          cpu: 50
          memory: 50
          pods: 20
        thresholds:
          cpu: 50
          memory: 50
          pods: 20
  RemoveDuplicates:
    enabled: true
  RemovePodsViolatingInterPodAntiAffinity:
    enabled: true
  RemovePodsViolatingNodeAffinity:
    enabled: true
    params:
      nodeAffinityType:
      - requiredDuringSchedulingIgnoredDuringExecution
  RemovePodsViolatingNodeTaints:
    enabled: true
```

Jan Chaloupka 077b7f6505 Drop check for MaxNoOfPodsToEvictPerNode and invoke EvictPod wrapper instead 2020-04-22 10:33:22 +02:00
Jan Chaloupka 240fa93bc5 Move maximum-pods-per-nodes-evicted logic under a single invocation 
Each strategy implements a test for checking if a maximum number of pods per node
was already evicted. The test duplicates a code that can be put
under a single invocation. Thus, reducing the number of arguments passed
to each strategy given EvicPod call can encapsulate both the check
and the invocation of the pod eviction itself.
