Clean Up

When you no longer need your Wazuh Kubernetes deployment or want a fresh deployment, it is important to properly remove all resources to prevent orphaned configurations or volumes from consuming cluster resources.

This section outlines the steps required to completely clean up your environment, including deleting StatefulSets, services, ConfigMaps, and persistent volumes associated with the Wazuh cluster.

Follow the steps below to delete all deployments, services, and volumes.

1. Remove the entire cluster

   The deployment of the Wazuh cluster of managers involves the use of different StatefulSet elements, as well as configuration maps and services.

   To delete your Wazuh cluster, execute the following command from the repository directory.

   EKS clusterOther cluster types

   $ kubectl delete -k envs/eks/
   

   This will remove every resource defined on the kustomization.yml file.

2. Run the following command from your repository directory to delete the Traefik ingress controller.

   # kubectl delete -k traefik/runtime/
   # kubectl delete -f traefik/crd/kubernetes-crd-definition-v1.yml
   

3. Remove the persistent volumes.

   $ kubectl get persistentvolume

   $ kubectl delete persistentvolume <PV_NAME>
   

   Replace <PV_NAME> with the name of the persistent volume, for example pvc-b3226ad3-f7c4-11e8-b9b8-022ada63b4ac.

   Repeat the kubectl delete command to delete all Wazuh related persistent volumes.
