Introduction

Welcome to the OpenStack Operator’s Manual for your OpenMetal Private Cloud! There are several phases of creating an OpenStack cloud and most of the public documentation focuses on the initial creation of a cloud. With OpenMetal, we provide a full private OpenStack cloud where you start as an Operator. This manual, with a few noted exceptions, applies to any OpenStack that has been provisioned to OpenStack.org’s RefStack standard. If you are reading this, it assumed you have followed the OpenMetal Central Process to provision your cloud already. Visit OpenMetal Central to sign up or sign in. For product details please visit the Private Cloud page.

Getting Started with the Operator’s Manual

Guides are grouped into Days, of which there are four. A description of each day and their associated guides follows in the Table of Contents.

Why Days?

Days have been selected to break down the information covered in this manual into categories. Loosely speaking, Day 1 is allocated for initial set up and configuration. Day 2 is for operations and maintenance. Day 3 has to do with scaling a cloud, ensuring your data is backed up, and how to restore it. Day 4 is for more advanced administration topics, introducing how to make general changes to your cloud using Kolla Ansible, and other topics.

Brief Summary of each Day

  • Day 1: Initial setup of cloud
  • Day 2: Cloud administration and maintenance
  • Day 3: Scaling the cloud and disaster recovery
  • Day 4: Advanced administration, introducing Kolla Ansible

Operator’s Manual Audience

The audience for this manual is experienced Linux System Administrators who are new to OpenStack.
