Deploy to OpenStack

This guide provides you with the steps to deploy a PCG cluster to an OpenStack environment. Before you begin the installation, carefully review the Prerequisites section.

Prerequisites​

  • Palette version 4.0.X or greater.

  • A Palette API key. Refer to the Create API Key page for guidance.

    warning

    The installation does not work with Single Sign-On (SSO) credentials. You must use an API key from a local tenant admin account in Palette to deploy the PCG. After the PCG is configured and functioning, this local account is no longer used to keep the PCG connected to Palette, so you can deactivate the account if desired.

  • Download and install the Palette CLI from the Downloads page. Refer to the Palette CLI Install guide to learn more.

The following system requirements must be met to install a PCG in OpenStack:

  • PCG IP address requirements:

    • One IP address for a single-node PCG or three IP addresses for a three-node PCG. Refer to the PCG Sizing section for more information on sizing.
    • One IP address reserved for cluster repave operations.
    • One IP address for the Virtual IP (VIP).
    • DNS can resolve the domain api.spectrocloud.com.

  • An x86 Linux environment with a Docker daemon installed and a connection to Palette and the OpenStack endpoint. The Palette CLI installation must be invoked on an up-to-date Linux system with the x86-64 architecture.

  • An Open Stack SSH Key Pair. Refer to the Configure access and security for instances guide to learn how to create an SSH key pair.

  • An OpenStack user account with the required permissions to deploy the PCG. Review the OpenStack Cloud Account Permissions section to learn more about the required permissions.
