Getting Started with a multi-node Kubernetes Provider

Download this repo

git clone https://github.com/kubevirt/kubevirtci.git
cd kubevirtci

Start multi node k8s cluster with 2 nics

export KUBEVIRT_PROVIDER=k8s-1.13.3 KUBEVIRT_NUM_NODES=2 KUBEVIRT_NUM_SECONDARY_NICS 1
make cluster-up

Stop k8s cluster

make cluster-down

Use provider's kubectl client with kubectl.sh wrapper script

cluster-up/kubectl.sh get nodes
cluster-up/kubectl.sh get pods --all-namespaces

Use your own kubectl client by defining the KUBECONFIG environment variable

export KUBECONFIG=$(cluster-up/kubeconfig.sh)

kubectl get nodes
kubectl apply -f <some file>

SSH into a node

cluster-up/ssh.sh node01

Attach to node console with socat and pty (non okd4 providers)

# Get node01 container id
node01_id=$(docker ps |grep node01 |awk '{print $1}')

# Install socat
docker exec $node01_id yum install -y socat

# Attach to node01 console
docker exec -it $node01_id socat - /dev/pts/0

Getting Started with multi-node OKD Provider

Download this repo

git clone https://github.com/kubevirt/kubevirtci.git
cd kubevirtci

Start okd cluster (pre-configured with a master and worker node)

export KUBEVIRT_PROVIDER=okd-4.1
make cluster-up

Stop okd cluster

make cluster-down

Use provider's OC client with oc.sh wrapper script

cluster-up/oc.sh get nodes
cluster-up/oc.sh get pods --all-namespaces

Use your own OC client by defining the KUBECONFIG environment variable

export KUBECONFIG=$(cluster-up/kubeconfig.sh)

oc get nodes
oc apply -f <some file>

SSH into master

cluster-up/ssh.sh master-0

SSH into worker

cluster-up/ssh.sh worker-0

Accessing OKD UI

TODO - in the process of working out the details here.
