# Podman Overview

Understand how to use Podman instead of Docker for Cortex XSOAR 6.14 on supported operating systems, including RHEL 8.

Cortex XSOAR supports both Docker and Podman as the container management tool. [Podman](https://podman.io/) is a daemonless container engine for developing, managing, and running OCI containers on the Linux System. Containers can either be run as root or in rootless mode.

When installing a server or engine, Cortex XSOAR automatically detects the container management type based on the operating system. For example, if your operating system is running RHEL v8 and higher, Cortex XSOAR installs Podman packages and configures the operating system to enable Podman in rootless mode.

{% hint style="info" %}
When upgrading a server or engine, the server or engine keeps the previously used container management type (regardless of distribution version). To migrate an existing server or engine to Podman, see [Migrate From Docker to Podman](/xsoar-6-administrator-guide/6.15/onboard-cortex-xsoar/podman/migrate-from-docker-to-podman.md).
{% endhint %}

If using PowerShell integrations, you may need to configure the default SELinux policy as Podman can affect processes which **`mmap`** to **`/dev/zero`**.

[Docker hardening](/xsoar-6-administrator-guide/6.15/onboard-cortex-xsoar/docker/docker-hardening-guide.md) guidelines can be applied to Podman, with the exception of Limit Available Memory, Limit Available CPU, and Limit PIDS.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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 following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/xsoar-6-administrator-guide/6.15/onboard-cortex-xsoar/podman/podman-overview.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case.

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.
