VirtualBox
Let’s install VirtualBox first.
Get latest stable version from https://www.virtualbox.org/wiki/Downloads
Linux: KVM2
Follow the instructions here: https://github.com/kubernetes/minikube/blob/master/docs/drivers.md#kvm2-driver
Kubectl
For Mac OS X:
curl -O https://storage.googleapis.com/kubernetes-release/release/v1.9.0/bin/darwin/amd64/kubectl \
&& chmod +x kubectl && sudo mv kubectl /usr/local/bin/
For Linux:
curl -O https://storage.googleapis.com/kubernetes-release/release/v1.9.0/bin/linux/amd64/kubectl \
&& chmod +x kubectl && sudo mv kubectl /usr/local/bin/
Minikube
For Mac OS X:
curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.25.0/minikube-darwin-amd64 \
&& chmod +x minikube && sudo mv minikube /usr/local/bin/
For Linux:
curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.25.0/minikube-linux-amd64 \
&& chmod +x minikube && sudo mv minikube /usr/local/bin/
Also, you can install drivers for various VM providers to optimize your minikube VM performance. Instructions can be found here: https://github.com/kubernetes/minikube/blob/master/docs/drivers.md.
Xcode and local tools
Xcode will install essential console utilities for us. You can install it from AppStore.
Set up cluster using minikube
To run cluster:
Mac OS
# starts minikube
minikube start --kubernetes-version=v1.9.0
# this command should work
kubectl get nodes
# use docker from minikube
eval $(minikube docker-env)
# this command to check connectivity
docker ps
Linux
# starts minikube
minikube start --kubernetes-version=v1.9.0 --vm-driver=kvm2
# this command should work
kubectl get nodes
# use docker from minikube
eval $(minikube docker-env)
# this command to check connectivity
docker ps
