1. Introduction

(info) Detail the approach of steps for StarlingX O-Cloud All-in-one Simplex deployment

1.1) Description

 The All-in-one Simplex (AIO-SX) deployment option provides all three cloud functions (controller, worker, and storage) on a single server with the following benefits:

  • Requires only a small amount of cloud processing and storage power

  • Application consolidation using multiple containers or virtual machines on a single physical server

  • A storage backend solution using a single-node CEPH deployment

1.2) System topology

2. Minimum Requirements

(info) Detail the hardware and software requirements necessary for the installation

  • Cores

    • Dual-CPU Intel® Xeon® E5 26xx family (SandyBridge) 8 cores/socket

    • or Single-CPU Intel® Xeon® D-15xx family, 8 cores (low-power/low-cost option)

  • RAM

    • 64GB

  • Storage

    • Primary Disk: 500 GB SSD or NVMe

    • Additional disks:

      • 1 or more 500 GB (min. 10K RPM) for Ceph OSD

  • Operating System

    • Debian 11 (bullsye), included in the StarlingX ISO installation.

  • More Details of the Requirements:

 

3. Installation

(info) step-by-step instructions for deployment

3.1)Step 1: Install OS and Software from ISO image

Expected Result: The OS and Software installation complete successfully and reboot into the system.

 

3.2) Step 2: Bootstrap system with ansible playbook

Expected Result: Ansible bootstrap playbook complete successfully.

 

3.3) Step 3: Configure and unlock controller-0

Expected Result: The system is unlocked and reboot successfully.

4. Post-Installation Verification

(info) Outline how to verify that the installation was successful.

4.1) Step 1: Check if the system is in state of unlocked, enabled and available

Expected Result:

[sysadmin@controller-0 ~(keystone_admin)]$ system host-list                                                                                                                                                                                                                   +----+--------------+-------------+----------------+-------------+--------------+                                                                                                                                                                                             | id | hostname     | personality | administrative | operational | availability |
+----+--------------+-------------+----------------+-------------+--------------+
| 1  | controller-0 | controller  | unlocked       | enabled     | available    |
+----+--------------+-------------+----------------+-------------+--------------+

4.2) Step 2: Check ceph cluster health if Ceph is configured:

Expected Result: 

[sysadmin@controller-0 ~(keystone_admin)]$ ceph -s                                                                                                                                                                                                                              cluster:                                                                                                                                                                                                                                                                        id:     8f463ab3-fcae-4003-b6f1-57563d98215a
