Install the OpenStack Operator

Using ArgoCD application to install RHOSO operators

The Red Hat OpenStack Services on OpenShift (RHOSO) IaaS services are implemented as a collection of Operators running on a Red Hat OpenShift Container Platform (RHOCP) cluster. These Operators manage the compute, storage, networking, and other services for your RHOSO cloud.

The OpenStack Operator (openstack-operator) installs all the required RHOSO service Operators and is the interface that you use to manage those Operators.

The basic architecture of a Red Hat OpenStack Services on OpenShift (RHOSO) environment includes the following features:

Container-native application delivery: RHOSO is delivered by using a container-native approach that spans the Red Hat OpenShift Container Platform (RHOCP) and RHEL platforms to deliver a container-native RHOSO deployment.
RHOCP-hosted services: RHOCP hosts infrastructure services and RHOSO controller services by using RHOCP Operators to provide lifecycle management.
Ansible-managed RHEL-hosted service: RHOSO workloads run on RHEL nodes that are managed by a dedicated DataPlane Operator. The DataPlane Operator runs Ansible jobs to configure the RHEL data plane nodes, such as the Compute nodes. RHOCP manages provisioning, DNS, and configuration management.
Installer-provisioned infrastructure: The RHOSO installer enables installer-provisioned infrastructure that uses RHOSO bare-metal machine management to provision the Compute nodes for the RHOSO cloud.
User-provisioned infrastructure: If you have your own machine ingest and provisioning workflow, you can use the RHOSO pre-provisioned model to add your pre-provisioned hardware into your RHOSO environment, while receiving the benefits of a container-native workflow.
Hosted RHOSO client: RHOSO provides a host openstackclient pod that is preconfigured with administrator access to the deployed RHOSO environment.

Create an argocd application manifest to deploy the prerequisites for the RHOSO control plane installation:

cat << EOF | oc apply -f -
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: openstack-operators-installation
  namespace: openshift-gitops
spec:
  project: default
  source:
    repoURL: 'https://github.com/rh-osp-demo/showroom_osp-on-ocp.git'
    targetRevision: HEAD
    path: content/files/manifests/openstack-operators-installation
  destination:
    server: 'https://kubernetes.default.svc'
    namespace: default
  syncPolicy:
    automated:
      prune: true
      selfHeal: false
    syncOptions:
    - CreateNamespace=true
EOF

Access the OpenShift Gitops console to check the deployment of the RHOSO operators

Review the pods in the openstack-operators namespace:
```
oc get pods -n openstack-operators
```

If you run:

oc get pods -n openstack-operators --sort-by=.metadata.creationTimestamp

You should see a list of completed pods and then the running openstack services pods. It should look like:

Sample Output
