Install Docker on engines and troubleshoot the installation.

Docker is required for engines to run Python/Powershell scripts and integrations in a controlled environment.

If you use the Shell installer to install an engine, Docker is automatically installed. If using DEB and RPM installations, you need to install Docker or Podman before installing an engine. The engine uses Docker to run Python scripts, PowerShell scripts, and integrations in a controlled environment. By packaging libraries and dependencies together, the environment remains the same and scripts and integrations are not affected by different server configurations.

Cortex XSIAM supports the latest Docker Engine release from Docker and the following corresponding supported Linux distributions:

  • 5.3.15 and later

  • 5.4.2 and later

  • 5.5 and later

These Linux distributions include their own Docker Engine package. In addition, older versions of Docker Engine released within the last 12 months are supported unless there is a known compatibility issue with a specific Docker Engine version. In case of a compatibility issue, Cortex XSIAM will publish an advisory notifying customers to upgrade their Docker Engine version.

You can use a version that is not supported. However, when encountering an issue that requires Customer Support involvement, you may be asked to upgrade to a supported version before assistance can be provided.

Docker Installation by Operating System

If you need to install Docker before installing an engine, use the following procedures.


For CentOS v7, you need Mirantis Container Runtime (formerly Docker Engine - Enterprise) or Red Hat's Docker distribution to run specific Docker-dependent integrations and scripts. For more information, see Install Docker Distribution for Red Hat on an Engine.

If you wish to use the Mirantis Container Runtime (formerly Docker Engine - Enterprise) follow the deployment guide for your operating system distribution.
