Local testing

If you'd like to test these Helm charts on your local machine first, follow the instructions below.

Prepare your Mac to run minikube with the following steps

brew install minikube
brew install hyperkit
brew install kubernetes-helm

Configure some defaults for minikube (optional)

minikube config set vm-driver hyperkit
minikube config set cpus 2
minikube config set memory 16384
minikube config set disk-size 50gb

Start minikube with RBAC enabled and configure Helm

minikube start --extra-config=apiserver.authorization-mode=RBAC
kubectl create clusterrolebinding add-on-cluster-admin --clusterrole=cluster-admin --serviceaccount=kube-system:default
kubectl -n kube-system create serviceaccount tiller
kubectl create clusterrolebinding tiller --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
helm init --service-account tiller --wait

From here on you can follow the steps as documented in the installation section above.
