# Docker

Install, configure, secure, and troubleshoot Docker for Cortex XSIAM engines.

Docker is a software framework for building, running, and managing containers.

{% hint style="info" %}
This section is relevant when installing an engine.
{% endhint %}

Cortex XSIAM maintains Docker images in the [Cortex Docker Hub organization](https://hub.docker.com/u/demisto/).

Each Python or PowerShell integration specifies its Docker image in its YAML file. If the image is not local, the engine downloads it from Docker Hub or the Cortex Container Registry. The integration then runs inside that container. For background information, see the [Docker documentation](https://docs.docker.com/) and [Using Docker](https://xsoar.pan.dev/docs/integrations/docker).

{% hint style="info" %}
You can [download Docker images](https://xsoar.pan.dev/docs/reference/articles/download-packs-offline) with their content packs for offline installation.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation 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/cortex-xsiam/configure-cortex-xsiam/engines/install-an-engine/docker.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 `automate deployments from our CI pipeline` 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.
