# Prohibit Root Containers in PMK Clusters

## Problem

* Self Service Users are able to create pods with root containers in PMK
* If mounted with the critical volume mounts like `/` , these pods can cause a serious security threat to the host and the underlying filesystem

## Environment

* Platform9 Managed Kubernetes - v5.6 and Higher

## Answer

* Platform9 is aware of this issue and an RFE is already in place for the same issue with ID: **PMK-6540**

## Additional Information

* Ensure the below criteria for all the applications

**Mount Only Necessary Directories:** If your application needs access to specific host directories, mount only those directories rather than the entire root filesystem.

**Use Read-Only Mounts:** If the container only needs to read data from the host, use a read-only mount to prevent any modifications.

**Run as Non-Root User:** Configure the container to run as a non-root user to limit its privileges within the container and on the host.

**Apply Security Policies:** Use Kubernetes security policies to enforce constraints on what containers can do, including restricting the host paths they can access.

## 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://platform9.com/kb/pmk/frequently-asked-questions/prohibit-root-containers-in-pmk-clusters.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.
