kubevirt-addon

Overview

The kubevirt-addon operator helps create Services, Routes, and Endpoints to expose services running on VMs, and create Endpoints to be aggregated to the MCM Hub cluster.

Deploy

1. Clone this repository

mkdir -p <project-directory>
cd <project-directory>
git clone https://github.ibm.com/steve-kim-ibm/kubevirt-addon.git
cd kubevirt-addon

2. Deploy the CRD and the operator

kubectl apply -f deploy/crds/app.ibm.com_kubevirtaddons_crd.yaml
kubectl apply -f deploy

3. Check that the operator is running

% kubectl get deploy 
NAME                        READY   UP-TO-DATE   AVAILABLE   AGE
kubevirt-addon              1/1     1            1           16s

Guestbook Example

This example will go through the deployment of Kubernetes' (Guestbook Application)[https://kubernetes.io/docs/tutorials/stateless-application/guestbook/] deployed through KubeVirt VMs and the KubeVirt-Addon operator.

0. Deploy the frontend, redis-slave, and redis-master VMs found under examples/guestbook/kubevirt-vms/

kubectl apply -f ./examples/guestbook/kubevirt-vms/frontend.yaml
kubectl apply -f ./examples/guestbook/kubevirt-vms/redismst.yaml
kubectl apply -f ./examples/guestbook/kubevirt-vms/redisslv.yaml

1. Deploy the kubevirt-addon resources for each VM. These can be found under examples/guestbook

kubectl apply -f ./examples/guestbook/01-redis-master.yaml
kubectl apply -f ./examples/guestbook/02-redis-slave.yaml
kubectl apply -f ./examples/guestbook/03-frontend.yaml

2. Ensure that the intended services, routes, and endpoints have been deployed successfully

% kubectl get svc,routes,endpoints -l app=guestbook

# TODO: display output

3. Go to the URL defined in the endpoint resource: (http://guestbook.apps.folie.os.fyre.ibm.com)

% kubectl describe endpoints -l app=guestbook

# TODO: display output
