Create cluster

Create a Kind cluster with Service Account Signing key for API Server for Kubeflow to work (Istio Needs it) like below

cat <<EOF | kind create cluster --name=kubeflow  --kubeconfig /home/dlovison/kindclusters/mycluster.yaml --config=-
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
  image: kindest/node:v1.28.0
  extraMounts:
  - containerPath: /var/lib/kubelet/config.json
    hostPath: /home/dlovison/.docker/config.json
  kubeadmConfigPatches:
  - |
    kind: ClusterConfiguration
    apiServer:
      extraArgs:
        "service-account-issuer": "kubernetes.default.svc"
        "service-account-signing-key-file": "/etc/kubernetes/pki/sa.key"

EOF

Save the config spec somewhere

kind get kubeconfig --name kubeflow > ~/.kube/config

Kubernetes Dashboard

helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/
helm upgrade --install kubernetes-dashboard kubernetes-dashboard/kubernetes-dashboard --create-namespace --namespace kubernetes-dashboard

kubectl apply -n kubernetes-dashboard -f - <<EOF
apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kubernetes-dashboard
EOF

kubectl apply -n kubernetes-dashboard -f - <<EOF
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kubernetes-dashboard
EOF

kubectl -n kubernetes-dashboard create token admin-user

kubectl -n kubernetes-dashboard port-forward svc/kubernetes-dashboard-kong-proxy 8443:443

while ! kustomize build example | kubectl apply -f -; do echo "Retrying to apply resources"; sleep 10; done

Double-check the installation

kubectl get pods -n cert-manager
kubectl get pods -n istio-system
kubectl get pods -n auth
kubectl get pods -n knative-eventing
kubectl get pods -n knative-serving
kubectl get pods -n kubeflow
kubectl get pods -n kubeflow-user-example-com
