Docker is a software framework for building, running, and managing containers. Cortex XSOAR uses Docker to run Python scripts, PowerShell scripts, and integrations in a controlled environment. Integrations are run isolated from the server, which prevents accidental damage to the server. By packaging libraries and dependencies together, the environment remains the same and scripts and integrations are not affected by different server configurations. Cortex XSOAR maintains a repository of Docker images, available in the Docker hub under the [Cortex XSOAR](https://hub.docker.com/u/demisto/) organization. You can also access the Docker images through the [Cortex XSOAR Container Registry](/xsoar-6-administrator-guide/6.14/onboard-cortex-xsoar/docker/docker-images-in-cortex-xsoar.md#UUID-5b0a4208-5f53-e2a6-17a1-fafc20c7f1d6). For Cortex XSOAR servers without an internet connection, you can download Docker images to another machine and copy them to the server. Each Python/PowerShell script or integration has a specific Docker image listed in the YAML file. When the script or integration runs, if the specified Docker image is not available locally, it is downloaded from the Docker hub or the Cortex XSOAR Container Registry. The script or integration then runs inside the Docker container. When creating an integration in Cortex XSOAR you are not required to “pip install” all required packages. The dependencies are part of a container that “docks” to the server and contains all libraries needed to run the integration. For more information on development, see the [Docker documentation](https://docs.docker.com/) and [Using Docker](https://xsoar.pan.dev/docs/integrations/docker). --- # 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 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/6.14/onboard-cortex-xsoar/docker/docker-overview.md?ask=&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.
