Setup on Minikube

Prerequisites

  1. Install kubectl

Install the Cluster

  1. Install the latest release of Minikube

  2. Start the Minikube cluster

    $ minikube start --cpus 2 --memory 8192

    You should see Kubectl is now configured to use the cluster

  3. Verify the Minikube cluster

    a. $ kubectl config use-context minikube

    You should see `Switched to context "minikube"`

    b. $ kubectl cluster-info

    You should see Kubernetes master is running at https://192.168.99.100:8443

    c. $ kubectl get nodes

    NAME STATUS ROLES AGE VERSION
    minikube Ready master 24d v1.10.0

Install the NGINX Ingress Controller

  1. Create configmaps; otherwise the ingress controller will throw Error getting ConfigMap

    $ kubectl apply -f https://github.com/kubernetes/minikube/blob/master/deploy/addons/ingress/ingress-configmap.yaml

  2. Enable the ingress add-on

    a. $ minikube addons enable ingress

    You should see ingress was successfully enabled

    b. $ kubectl -n kube-system get pods

    NAMESPACE NAME READY STATUS RESTARTS AGE
    kube-system nginx-ingress-controller-xxxxxxxxxx-xxxxx 1/1 Running 0 39s

    Wait for the controller to start. It may take a few minutes.

  3. Review the logs to verify the installation. This is also useful for troubleshooting ingress resources.

    $ kubectl -n kube-system logs <POD_NAME>

    You should see successfully acquired lease kube-system/ingress-controller-leader-nginx

Install the Helm Server (Tiller)

To install tiller into the minikube cluster

  1. $ kubectl use-context minikube

  2. $ helm init.

    This command validates the helm client is installed correctly and initializes it up if necessary. Then, it connects to the minikube cluster and installs tiller into the kube-system namespace.

  3. $ kubectl -n kube-system get pods

    You should see tiller running

    NAMESPACE NAME READY STATUS RESTARTS AGE
    kube-system tiller-deploy-xxxxxxxxxx-xxxxx 1/1 Running 0 39s

    Wait for the tiller to start. It may take a few minutes.

  4. Review the logs to verify the installation.

    $ kubectl -n kube-system logs POD_NAME

    You should see Starting Tiller v2.11.0 (tls=false)

Install the Kubernetes Dashboard (Optional)

The Kubernetes Dashboard can be useful for managing and troubleshooting your cluster

$ minikube dashboard

This command opens the Kubernetes Dashboard in a browser
