- On new desired state:
- Mark as progressing during reconciliation
- Remove old status conditions, since they are now stale
- Replace boolean status fields with status conditions, and remove unimplemented ones for now
- Move to kubernetes 1.20 libraries to inclue a status condition bugfix [0]
- Ensure requeue on status update failures

ViNO Cluster Operator
Overview
The lifecycle of the Virtual Machines and their relationship to the Kubernetes cluster will be managed using two operators: vNode-Operator(ViNO), and the Support Infra Provider Operator (SIP).
Description
ViNO is responsible for setting up VM infrastructure, such as:
- per-node vino pod:
- libvirt init, e.g.
- setup vm-infra bridge
- provisioning tftp/dhcp definition
- libvirt launch
- sushi pod
- libvirt init, e.g.
- libvirt domains
- networking
- bmh objects, with labels:
- location - i.e.
rack: 8
andnode: rdm8r008c002
- should follow k8s semi-standard - vm role - i.e.
node-type: worker
- vm flavor - i.e
node-flavor: foobar
- networks - i.e.
networks: [foo, bar]
and the details for ViNO can be found here
- location - i.e.
The Cluster Support Infrastructure Provider, or SIP, is responsible for the lifecycle of:
- identifying the correct
BareMetalHost
resources to label (or unlabel) based on scheduling constraints. - extract IP address information from
BareMetalHost
objects to use in the creation of supporting infrastructure. - creating support infra for the tenant k8s cluster:
- load balancers (for tenant Kubernetes API)
- jump pod to access the cluster and nodes via ssh
- an OIDC provider for the tenant cluster, i.e. Dex
- potentially more in the future
Development Environment
Pre-requisites
Install Golang 1.15+
ViNO is a project written in Go, and the make targets used to deploy ViNO leverage both Go and Kustomize commands which require Golang be installed.
For detailed installation instructions, please see the Golang installation guide.
Install Kustomize v3.2.3+
In order to apply manifests to your cluster via Make targets we suggest the use of Kustomize.
For detailed installation instructions, please see the Kustomize installation guide.
Proxy Setup
If your organization requires development behind a proxy server, you will need to define the following environment variables with your organization's information:
HTTP_PROXY=http://username:password@host:port
HTTPS_PROXY=http://username:password@host:port
NO_PROXY="localhost,127.0.0.1,10.96.0.0/12"
PROXY=http://username:password@host:port
USE_PROXY=true
10.96.0.0/12 is the Kubernetes service CIDR.
Deploy ViNO
Airship projects often have to deploy Kubernetes, with common requirements such as supporting network policies or working behind corporate proxies. To that end the community maintains a Kubernetes deployment script and is the suggested way of deploying your Kubernetes cluster for development purposes.
Deploy Kubernetes
# curl -Lo deploy-k8s.sh https://opendev.org/airship/charts/raw/branch/master/tools/gate/deploy-k8s.sh
# chmod +x deploy-k8s.sh
# sudo ./deploy-k8s.sh
Deploy ViNO
Once your cluster is up and running, you'll need to build the ViNO image to use, and to deploy the operator on your cluster:
# make docker-build-controller
# make deploy
Once these steps are completed, you should have a working cluster with ViNO deployed on top of it:
# kubectl get pods --all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE

kube-system storage-provisioner 1/1 Running 0 3h8m
vino-system vino-controller-manager-788b994c74-sbf26 2/2 Running 0 25m
Test basic functionality
# kubectl apply -f config/samples/vino_cr.yaml
# kubectl get pods
# kubectl get ds
delete vino CR and make sure DaemonSet is deleted as well
# kubectl delete vino vino-test-cr
# kubectl get ds
# kubectl get cm

For any questions on the ViNo, or other Airship projects, we encourage you to join the community on Slack/IRC or by participating in the mailing list. Please see this Wiki for contact information, and the community meeting schedules.
