• Download links for Docker for Mac: https://www.docker.com/docker-mac

Command to test: docker version

Virtualbox

• Download link: https://www.virtualbox.org/

Command to test: virtualbox

Kubectl:

• Download link: https://kubernetes.io/docs/tasks/tools/install-kubectl/#install-kubectl-binary-via-curl

Command to test: kubectl version

Minikube:

• Download link: https://github.com/kubernetes/minikube/releases

Command to test: minikube version

My environment status

MacOS      \  10.13.4
docker     \  18.03   
kubectl    \  1.10
minicube   \  0.26

setup code

curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.10.0/bin/darwin/amd64/kubectl && chmod +x ./kubectl && sudo mv ./kubectl /usr/local/bin/kubectl
curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.26.2/minikube-darwin-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

2 Setup and test Minikube

prepare local VPN connection env and run

minikube start --docker-env http_proxy=http://192.168.99.1:8118 --docker-env https_proxy=http://192.168.99.1:8118 --docker-env no_proxy=127.0.0.1, localhost, 192.168.0.0/16, 10.0.0.0/8

check minikube run all right

minikube ssh
docker images 

you should be able to see below images.

in order to make the lab demonstration fast without waiting, let pull the docker images first. In minikube run

docker pull k8s.gcr.io/heapster-amd64:v1.5.0
docker pull gcr.io/google-containers/kube-addon-manager:v6.5
docker pull karthequian/secretreader:latest
docker pull karthequian/reader:latest
docker pull karthequian/helloworld:blue
docker pull karthequian/helloworld:black
docker pull karthequian/helloworld:latest
docker pull k8s.gcr.io/k8s-dns-sidecar-amd64:1.14.5
docker pull k8s.gcr.io/k8s-dns-kube-dns-amd64:1.14.5
docker pull k8s.gcr.io/k8s-dns-dnsmasq-nanny-amd64:1.14.5

3. Setup and test kubectl

kubectl get pods
kubectl get nodes
