To uninstall Vault CSI driver, run the following command:
In Helm 3, release names are scoped to a namespace. So, provide the namespace you used to install the CSI driver when installing.
$ helm uninstall csi-vault --namespace kube-system
$ helm delete csi-vault
If you prefer to not use Helm, you can generate YAMLs from Vault CSI driver chart and uninstall using kubectl.
$ helm template vault-operator appscode/csi-vault --namespace kube-system | kubectl delete -f -
