OpenStack Probe Configuration Management

This document describes a unified approach to managing Kubernetes probes in RHOSO (liveness, readiness, and startup) across service operators, based on an existing lib-common module [0].

Overview

The probe configuration system addresses two key aspects:

User customization: How services can define overrides for probe configurations
Operator consumption: How operators can consume these overrides through a consistent, type-safe interface

Step 1: Create Pool and configure allow_ec_overwrites

$ ceph osd pool create images_data erasure
$ ceph osd pool create images_meta replicated
$ ceph osd pool set images_data allow_ec_overwrites true

Note: allow_ec_overwrites is required and must be set in Ceph.

Verification steps:

Building custom OpenStack images

This document outlines the hotfix process for an OpenStack service deployed on OpenShift. The procedure assumes the following:

Internal Registry Usage: Use the OpenShift internal container image registry instead of a third-party registry. To enable access from EDPM nodes, expose the registry via an OpenShift Route.

Topology and Affinity notes

oc label nodes master-0 node=node0 zone=zoneA --overwrite
oc label nodes master-1 node=node1 zone=zoneB --overwrite
oc label nodes master-2 node=node2 zone=zoneC --overwrite

External Ceph - ROOK / CRC

This guide outlines how to set up an external Ceph cluster using the ROOK operator in a CRC (CodeReady Containers) or SNO (Single Node OpenShift) environment. The instructions assume you're using the install_yamls project and openstack-ceph scripts for development tools.

The setup involves 2 nodes:

a crc environment that can be replaced by a SNO
