minikube 安装试用

目前使用k8s 要么用的物理机搭建的环境，要么就是使用docker for mac 中kubernetes 的特性，为了本地调试方便，使用下minikube

minukube 包含的特性

• 负载均衡器
• 多集群
• nodeports 支持
• 持久化数据卷
• ingress
• dashboard
• 执行容器运行时
• 配置apiserver 以及kubelet选项
• addons 支持
• nvidia GPU 支持
• 文件系统挂载

下载安装包

直接可以在github 下载

配置环境变量

配置到path 路径即可

启动

minukube 实际上是kubeadm 安装的，同时minikube 在启动的时候我们可以配置比较多的参数，比如执行镜像源，配置docker 加速
配置主机内存的大小

• 启动命令

 

minikube start --help

Starts a local kubernetes cluster

Options:

      --apiserver-ips=[]: A set of apiserver IP Addresses which are used in the generated

certificate for kubernetes. This can be used if you want to make the apiserver available from

outside the machine

different components.

  The key should be '.' separated, and the first part before the dot is the component to apply the

configuration to.

  Valid components are: kubelet, kubeadm, apiserver, controller-manager, etcd, proxy, scheduler

For Chinese mainland users, you may use local gcr.io mirrors such as

registry.cn-hangzhou.aliyuncs.com/google_containers

      --insecure-registry=[]: Insecure Docker registries to pass to the Docker daemon. The default

service CIDR range will automatically be added.

Usage:

  minikube start [flags] [options]

• 启动
  从上边的帮助上我们可以看出还是比较全的参数控制，启动也比较简单

minikube start --image-mirror-country=cn --registry-mirror=https://b3uey254.mirror.aliyuncs.com
