# Podman

[Podman](https://podman.io/) is a daemonless container engine for developing, managing, and running [OCI Containers](https://opencontainers.org/) on the Linux System. Containers can either be run as root or in rootless mode.

If you use the Shell installer to install an 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.

### Note

When upgrading an engine, the engine keeps the previously used container management type (regardless of distribution version).
{% 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 guidelines**

Docker hardening guidelines can be applied to Podman, with the exception of Limit Available Memory, Limit Available CPU, and Limit PIDS.

## 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/cortex-xsoar-8-on-prem/8.12/configure-cortex-xsoar/engines/install-an-engine/podman.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.
