使用 Minikube 部署 Kubernetes 集群
环境确认
# 确认宿主机是否支持虚拟化，支持的话下面命令有内容输出
egrep --color 'vmx|svm' /proc/cpuinfo
单机部署
Installing minikube
Install kubectl
直接二进制安装最新版本
curl -LO https://storage.googleapis.com/kubernetes-release/release/`curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/linux/amd64/kubectl
# 赋予可执行权限
chmod +x ./kubectl
# Move the binary in to your PATH.
sudo mv ./kubectl /usr/local/bin/kubectl
# Test to ensure the version you installed is up-to-date:
kubectl version
# 输出信息如下

Install a Hypervisor
# 安装KVM，参考链接：https://www.cyberciti.biz/faq/installing-kvm-on-ubuntu-16-04-lts-server/
sudo apt-get install qemu-kvm libvirt-bin virtinst bridge-utils cpu-checker
# 确认安装
➜ kvm-ok
INFO: /dev/kvm exists

二进制安装 minikube
# download
curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 \
&& chmod +x minikube
# install
sudo install minikube /usr/local/bin
# confirm
