The images built from ViNO code are not currently stored in a public registry, this change adds Zuul jobs to push the controller and nodelabeler images to Quay.io where they can be consumed by the community.

ViNO Cluster Operator
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).
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
- bmh objects, with labels:
- location - i.e.
node: rdm8r008c002- should follow k8s semi-standard
- vm role - i.e.
- vm flavor - i.e
- 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
BareMetalHostresources to label (or unlabel) based on scheduling constraints.
- extract IP address information from
BareMetalHostobjects 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
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.
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.
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.
# 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
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 calico-kube-controllers-7985fc4dd6-6q5l4 1/1 Running 0 3h7m kube-system calico-node-lqzxp 1/1 Running 0 3h7m kube-system coredns-f9fd979d6-gbdzl 1/1 Running 0 3h7m kube-system etcd-ubuntu-virtualbox 1/1 Running 0 3h8m kube-system kube-apiserver-ubuntu-virtualbox 1/1 Running 0 3h8m kube-system kube-controller-manager-ubuntu-virtualbox 1/1 Running 0 3h8m kube-system kube-proxy-ml4gd 1/1 Running 0 3h7m kube-system kube-scheduler-ubuntu-virtualbox 1/1 Running 0 3h8m 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 # kubect get pods # kubectl get ds
test with user provided template
# kubectl apply -f config/samples/daemonset_template.yaml # kubectl apply -f config/samples/vin_cr_daemonset_template.yaml # kubectl get pods # kubectl get ds
delete vino CR and make sure DaemonSet is deleted as well
# kubectl delete vino vino # kubectl get ds
