Change the Docker image in an integration or script - Administrator Guide - 8 - Cortex XSOAR - Cortex - Security Operations

Docker enables you to run scripts and integrations from an image in a controlled environment that isolates and safeguards the server. It also simplifies environment setup by packaging dependencies and configurations within an image, ensuring consistent execution across different systems. By default, Cortex XSOAR pulls images from the Demisto Docker image registry in Github, which are used in scripts and integrations as needed.  Cortex XSOAR integrations and scripts have the relevant Docker image already selected. For example, the Rasterize integration uses the demisto/python.3.3.11.9.1079 Docker image.

You may want to select a different Docker image for your integration or script. In Cortex XSOAR, you can select a different Docker image from a dropdown that is pulled from the Demisto Docker image registry. In Github, the dockerfiles-info branch contains information about each image to help you find one that is relevant.

Alternatively, instead of pulling publicly available images in the Demisto registry, you can pull images from a private authenticated image registry. For more information, see Pull images from a private image registry.

You can pull Docker images either directly or through an engine. If using an engine to pull Docker images from a private authenticated registry, you first need to configure the authentication on the engine machine. For more information, see Connect an engine to an image registry.
