Description

Tiller (Helm v2) must not be deployed because it is deprecated and no longer supported. This rule detects resources that reference Tiller by resource name or labels (for example, metadata.name, metadata.labels.app == "helm", or a metadata.labels.name containing “tiller”). It also detects Tiller container images by name in containers or initContainers, including within pod templates (spec.template).
