Set up a Kubernetes cluster

General

Kind will be used as the k8s runtime environment as it can easily run on all environments, and does not require any complicated steps to setup.

Install Kind

See: installing Kind

Create Kind Demo Cluster

Use kind to create the customized cluster:

kind create cluster --config=env/cluster.yaml --name=demo --image=docker.io/kindest/node:v1.16.3@sha256:70ce6ce09bee5c34ab14aec2b84d6edb260473a60638b1b095470a3a0f95ebec

NOTE: The latest version of kind and the kind container version can be found here

Set up the Kubernetes environment

Install Calico for NetworkPolicy support:

kubectl apply -f env/calico.yaml

Install Helm tiller on kube-system

kubectl apply -f kind/tiller.yaml

Verifying the cluster is ready:

kubectl get pods -A

Should show:
