Getting Started with Scalar Helm Charts

This document explains how to get started with Scalar Helm Chart on a Kubernetes cluster as a test environment. Here, we assume that you already have a Mac or Linux environment for testing. We use Minikube in this document, but the steps we will show should work in any Kubernetes cluster.

Tools​

We will use the following tools for testing.

  1. minikube (If you use other Kubernetes distributions, minikube is not necessary.)
  2. kubectl
  3. Helm
  4. cfssl / cfssljson

Step 1. Install tools​

First, you need to install the following tools used in this guide.

  1. Install the minikube command according to the minikube documentation

  2. Install the kubectl command according to the Kubernetes documentation

  3. Install the helm command according to the Helm documentation

  4. Install the cfssl and cfssljson according to the CFSSL documentation

note

You need to install the cfssl and cfssljson command when following these getting started guides:

Step 2. Start minikube with docker driver (Optional / If you use minikube)​

  1. Start minikube.

    minikube start

  2. Check the status of the minikube and pods.

    kubectl get pod -A

    [Command execution result]

    NAMESPACE     NAME                               READY   STATUS    RESTARTS      AGE
    kube-system   coredns-64897985d-lbsfr            1/1     Running   1 (20h ago)   21h
    kube-system   etcd-minikube                      1/1     Running   1 (20h ago)   21h
    kube-system   kube-apiserver-minikube            1/1     Running   1 (20h ago)   21h
    kube-system   kube-controller-manager-minikube   1/1     Running   1 (20h ago)   21h
    kube-system   kube-proxy-gsl6j                   1/1     Running   1 (20h ago)   21h
    kube-system   kube-scheduler-minikube            1/1     Running   1 (20h ago)   21h
    kube-system   storage-provisioner                1/1     Running   2 (19s ago)   21h

    If the minikube starts properly, you can see some pods are Running in the kube-system namespace.

Step 3.​

After the Kubernetes cluster starts, you can try each Scalar Helm Charts on it. Please refer to the following documents for more details.
