ironic-operator

A Kubernetes Operator built using the Operator Framework for Go. The Operator provides a way to easily install and manage an OpenStack Ironic installation on Kubernetes. This Operator was developed using RDO containers for openStack.

Deployment

The operator is intended to be deployed via OLM Operator Lifecycle Manager

Example

The Operator creates a custom Ironic resource that can be used to create Ironic API and conductor instances within the cluster. Example CR to create an Ironic in your cluster:

apiVersion: ironic.openstack.org/v1beta1
kind: Ironic
metadata:
  name: ironic
  namespace: openstack
spec:
  serviceUser: ironic
  customServiceConfig: |
    [DEFAULT]
    debug = true
  databaseInstance: openstack
  databaseUser: ironic
  ironicAPI:
    replicas: 1
    containerImage: quay.io/tripleomastercentos9/openstack-ironic-api:current-tripleo
  ironicConductor:
    replicas: 1
    containerImage: quay.io/tripleomastercentos9/openstack-ironic-conductor:current-tripleo
    pxeContainerImage: quay.io/tripleomastercentos9/openstack-ironic-pxe:current-tripleo
  secret: ironic-secret

Design

The current design takes care of the following:

• Creates ironic config files via config maps
• Creates an ironic deployment with the specified replicas
• Creates an ironic service
• Ironic bootstrap, and db sync are executed automatically on install and updates
• ConfigMap is recreated on any changes Ironic object changes and the Deployment updated.
