Helm

To install helm-cli run curl -L https://git.io/get_helm.sh | bash

helm init

kubectl apply -f 2_private-ingress/helm-rbac.yaml

kubectl create serviceaccount --namespace kube-system tiller

kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller

kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'

helm init --service-account tiller --node-selectors "beta.kubernetes.io/os"="linux" --upgrade

Private Ingress

Create a namespace for the ingress resources kubectl apply -f 2_private-ingress/backend-namespace.yaml

In the file 2_private-ingress/internal-ingress.yaml you need to set the IP do you want to use.

Use Helm to deploy an NGINX ingress controller

helm install stable/nginx-ingress \
    --namespace backend \
    -f 2_private-ingress/internal-ingress.yaml \
    --set controller.replicaCount=2 \
    --set controller.nodeSelector."beta\.kubernetes\.io/os"=linux \
    --set defaultBackend.nodeSelector."beta\.kubernetes\.io/os"=linux
