Open Source MANO (OSM) v11 install with --k8s_monitor ERROR

Question

When I install OSM with --k8s_monitor, I am getting error below:

Checking if helm-tiller is installed...
The connection to the server localhost:8080 was refused - did you specify the right host or port?
error: failed to create clusterrolebinding: Post "http://localhost:8080/apis/rbac.authorization.k8s.io/v1/clusterrolebindings?fieldManager=kubectl-create": dial tcp 127.0.0.1:8080: connect: connection refused
Error: unknown command "init" for "helm"

Did you mean this?
        lint

Run 'helm --help' for usage.
The connection to the server localhost:8080 was refused - did you specify the right host or port?
Waiting for tiller READY....
The connection to the server localhost:8080 was refused - did you specify the right host or port?

Looks like the installation is using new version of Helm which does not require initialisation.

I found a piece of code here under /usr/share/osm-devops/installer/k8s/install_osm_k8s_monitoring.sh

echo "Checking if helm-tiller is installed..."
kubectl --namespace kube-system get serviceaccount tiller > /dev/null 2>&1
if [ $? == 1 ] ; then
# tiller account for kubernetes
kubectl --namespace kube-system create serviceaccount tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
# HELM initialization
helm init --stable-repo-url https://charts.helm.sh/stable --service-account tiller

# Wait for Tiller to be up and running
while true
do
tiller_status=`kubectl -n kube-system get deployment.apps/tiller-deploy --no-headers |  awk '{print $2'}`
    if  [ ! -z "$tiller_status" ]
    then
        if [ $tiller_status == "1/1" ]
        then
            echo "Go...."
            break
        fi
    fi
    echo "Waiting for tiller READY...."
    sleep 2
done
fi

Which I don't is necessary any more as new version of Helm does not require initialisation and tiller.

Thank you.
