Setup on Minikube

Prerequisites

  1. Install kubectl

  2. Install Minikube according to the instructions for the latest release

What's next

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
