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.
- Populate extension points automatically from plugin types
- Make a list of enabled extension points based on a profile
configuration
- Populate filter and pre-eviction filter handles from their
corresponding extension points
* 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
* add v1alpha2 registry based conversion
* test defaults, set our 1st explicit default
* fix typos and dates
* move pluginregistry to its own dir
* remove unused v1alpha2.Namespace type
* move migration code folders, remove switch
* validate internalPolicy a single time
* remove structured logs
* simplify return
* check for nil methods
* properly check before adding default evictor
* add TODO comment
* bump copyright year
* use plugin registry and prepare for conersion
* Register plugins explicitly to a registry
* check interface impl instead of struc var
* setup plugins at top level
* treat plugin type combinations
* pass registry as arg of V1alpha1ToInternal
* move registry yet another level up
* check interface type separately
* 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
