# Non-Critical System Pods Run on System Nodes misconfiguration detected in code

## Impact

This rule checks to ensure that only critical system pods are running on system nodes in a Kubernetes environment on Azure. This is important because allowing non-critical pods to run on system nodes can introduce security vulnerabilities, potential performance issues, and a decrease in reliability. If a non-critical pod is compromised, it could potentially impact the critical system pods by using up system resources or creating other issues due to cohabitation. As such, following this rule aids in ensuring system stability and security.

## How to Fix

*Resource:* azurerm\_kubernetes\_cluster

* *Arguments:* default\_node\_pool.only\_critical\_addons\_enabled

## To fix this issue, you need to ensure that only critical system pods are allowed to run on your system nodes. You can do this by adding the Pod Tolerations and Node Affinity settings. \[source,go]

resource "azurerm\_kubernetes\_cluster" "pass" { name = "example"

default\_node\_pool { name = "defaultpool"

* only\_critical\_addons\_enabled = true } }

## 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-azure-232.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.
