The Evict extension point is not currently in use.
All DefaultEvictor plugin functionality is exposed through Filter and
PreEvictionFilter extension points instead.
Thus, no need to limit the number of evictors enabled.
* Descheduling profile
* Fake plugin + profile unit testing
* Rename Profile config type into DeschedulerProfile
To avoid resamblance with profileImpl
* First run deschedule, then balance extension points
* Remove log level from Errors
Every error printed via Errors is expected to be important and always
printable.
* Invoke first Deschedule and then Balance extension points (breaking change)
* Separate plugin arg conversion from pluginsMap
* Seperate profile population from plugin execution
* Convert strategy params into profiles outside the main descheduling loop
Strategy params are static and do not change in time.
* Bump the internal DeschedulerPolicy to v1alpha2
Drop conversion from v1alpha1 to internal
* add tests to v1alpha1 to internal conversion
* add tests to strategyParamsToPluginArgs params wiring
* in v1alpha1 evictableNamespaces are still Namespaces
* add test passing in all params

Add taint exclusion to RemovePodsViolatingNodeTaints. This permits node
taints to be ignored by allowing users to specify ignored taint keys or
ignored taint key=value pairs.
This patch adds the policy(evictFailedBarePods) to allow the failed
pods without ownerReferences to be evicted. For backward compatibility,
disable the policy by default. Address #644.
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.
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.
