Uninstall Consul

Consul can be uninstalled via the helm delete command:

  1. $ helm delete hashicorp
  2. release "hashicorp" uninstalled

If using Helm 2, run helm delete --purge hashicorp

After deleting the Helm release, you need to delete the PersistentVolumeClaim‘s for the persistent volumes that store Consul’s data. These are not deleted by Helm due to a bug. To delete, run:

  1. $ kubectl get pvc -l chart=consul-helm
  2. NAME                                   STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
