Dry Run

Introduction to Dry Run

To preview which resources match the Cleaner's criteria, set the Action field to Scan. The k8s-cleaner will still execute its logic but will not delete and/or update any resources.

To identify matching resources, you can then either ask k8s-cleaner to generate a Report or search the controller logs for the message resource is a match for cleaner.

Example - Dry Run

The example below, provides a definition of eliminating Deployments in the test namespace with both the serving=api and the environment!=production labels set.

---
apiVersion: apps.projectsveltos.io/v1alpha1
kind: Cleaner
metadata:
  name: cleaner-sample1
spec:
  schedule: "* 0 * * *" # Runs every day at midnight
  resourcePolicySet:
    resourceSelectors:
    - namespace: test
      kind: Deployment
      group: "apps"
      version: v1
      labelFilters:
      - key: serving
        operation: Equal
        value: api # Match deployments with the "serving" label set to "api"
      - key: environment
        operation: Different
        value: production # Match deployments with the "environment" label different from "production"
  action: Scan

By setting the Action field to Scan, we can safely test the Cleaner's filtering logic without affecting your actual deployment configurations. Once we are confident in the filtering criteria, you can set the Action to delete or modify.
