## Impact

Tiller (Helm v2) is the in-cluster component of Helm. It interacts directly with the Kubernetes API server to install, upgrade, query, and remove Kubernetes resources. It also stores the objects that represent releases. Its permissive configuration could grant the users a broad range of permissions. New versions of Kubernetes and Helm v3 have made Tiller obsolete, with its over permissive function in existing workloads remaining a security liability. Consider upgrading to use Helm v3, which only runs on client machines. Not all charts may support Helm 3, but the number that do is growing rapidly.

## How to Fix

*Resource:* Container

* *Arguments:* labels:app / name - specifies the app label for the pod image - defines the image used by the container \[source,go]

***

apiVersion: v1 kind: Pod metadata: name: labels:

* app: helm
* name: tiller spec: containers:
* name:
* image: tiller

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/compute/appsec-k8s-34.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
