chore: log average and assessed thresholds
 2025-03-28 06:52:40 -07:00
Ricardo Maraschini 98e6ed6587 chore: log average and assessed thresholds 
when calculating the average an applying the deviations it would be nice
to also see the assessed values.

this commit makes the descheduler logs these values when using level 3.

Jan Chaloupka 5bf11813e6 lownodeutilization: evictionLimits to limit the evictions per plugin 
In some cases it might be usefull to limit how many evictions per a
domain can be performed. To avoid burning the whole per descheduling
cycle budget. Limiting the number of evictions per node is a
prerequisite for evicting pods whose usage can't be easily subtracted
from overall node resource usage to predict the final usage. E.g. when a
pod is evicted due to high PSI pressure which takes into account many
factors which can be fully captured by the current predictive resource
model.

Ricardo Maraschini 57a04aae9f chore: add descheduler plugin example 
This commit adds a sample plugin implementation as follow:

This directory provides an example plugin for the Kubernetes Descheduler,
demonstrating how to evict pods based on custom criteria. The plugin targets
pods based on:

* **Name Regex:** Pods matching a specified regular expression.
* **Age:** Pods older than a defined duration.
* **Namespace:** Pods within or outside a given list of namespaces (inclusion
  or exclusion).

To incorporate this plugin into your Descheduler build, you must register it
within the Descheduler's plugin registry. Follow these steps:

1.  **Register the Plugin:**
    * Modify the `pkg/descheduler/setupplugins.go` file.
    * Add the following registration line to the end of the
      `RegisterDefaultPlugins()` function:

    ```go
    pluginregistry.Register(
      example.PluginName,
      example.New,
      &example.Example{},
      &example.ExampleArgs{},
      example.ValidateExampleArgs,
      example.SetDefaults_Example,
      registry,
    )
    ```

2.  **Generate Code:**
    * If you modify the plugin's code, execute `make gen` before rebuilding the
      Descheduler. This ensures generated code is up-to-date.

3.  **Rebuild the Descheduler:**
    * Build the descheduler with your changes.

Configure the plugin's behavior using the Descheduler's policy configuration.
Here's an example:

```yaml
apiVersion: descheduler/v1alpha2
kind: DeschedulerPolicy
profiles:
- name: LifecycleAndUtilization
  plugins:
    deschedule:
      enabled:
        - Example
  pluginConfig:
  - name: Example
    args:
      regex: ^descheduler-test.*$
      maxAge: 3m
      namespaces:
        include:
        - default
```

- `regex: ^descheduler-test.*$`: Evicts pods whose names match the regular
  expression `^descheduler-test.*$`.
- `maxAge: 3m`: Evicts pods older than 3 minutes.
- `namespaces.include: - default`: Evicts pods within the default namespace.

This configuration will cause the plugin to evict pods that meet all three
criteria: matching the `regex`, exceeding the `maxAge`, and residing in the
specified namespace.
