    Installation Overview

    The Contrail Controller is typically installed on multiple servers. The base software image is installed on all servers to be used, then provisioning scripts are run that launch role-based components of the software.

    The roles used for the installed system include:

    • cfgm—Runs Contrail configuration manager (config-node)
    • openstack—Runs OpenStack services such as Nova, Quantum, and the like
    • collector—Runs monitoring and analytics services
    • compute—Runs vRouter service and launches tenant virtual machines (VMs)
    • control—Runs the control plane service
    • database—Runs analytics and configuration database services
    • webui—Runs the administrator web-based user interface service

    The roles are run on multiple servers in an operating installation. A single node can have multiple roles. The roles can also run on a single server for testing or demonstration purposes.

    Installing the Operating System and Contrail Packages describes installing the Contrail Controller software onto multiple servers.

    Your account team can help you determine the number of servers needed for your specific implementation.
