⽆缝对接新的应⽤功能 节省资源，优化硬件资源的使⽤ Minikube 简介 Minikube 可以实现⼀种轻量级的 Kubernetes 集群，通过在本地计算机上创建虚拟机并部署只包含单个节点的简单集群 MacOS 系统安装依赖 安装依赖 # 命令⾏⼯具 brew install kubectl brew install minikube # 如果遇到权限⽂图 sudo chown ⽂件中查看所有可⽤的环境 启动 # 可添加参数 # --vm-driver=hyperkit minikube start minikube dashboard Minikube Dashboard Docker Desktop Dashboard（MasOC） minikube start 回启动⼀个 Docker 容器： 打包 Nodejs 应⽤镜像 创建 Nodejs ClusterIP 10.96.0.1 443/TCP 16h 浏览器访问 Service 可以通过minikube Service 命令访问。 minikube service hello-node 会即刻打开浏览器，显示 “Hello World” 消息。 更新 Nodejs 应⽤镜像和服务 修改 Nodejs 程序并出新镜像：

Kubernetes cluster with Istio running within it. Instead, NCC Group used various hosting options (i.e. Minikube, GKE, KOPS) to build reference clusters and test various configurations. These reference architectures Cluster The assessment was performed using a variety of types environments including GCP, AWS, minikube, and GKE but for reference, each of the findings can be found within the reference cluster architecture installation steps used for creating a minikube cluster with the versions of Istio relevant to this assessment. These steps assume a Ubuntu 18.04.4 LTS machine with minikube20 configured to use KVM, and Go installed

10，Docker已经原⽣⽀持了Kubernetes。你所要做的只是启⽤Kubernetes即可，如下图： Minikube ⼀些场景下，安装Minikube是个不错的选择。该⽅式适⽤于Windows 10、Linux、macOS 官⽅安装说明⽂档：https://github.com/kubernetes/minikube 如何在Windows 10上运⾏Docker和Kubernetes？：http://dockone 本节中的示例需要安装Heapster。因此，需要先安装Heapster，对于Minikube，执⾏如下操作即可。 minikube addons enable heapster 查看Heapster Service是否已在运⾏： kubectl get services --namespace=kube-system TIPS 按理，对于Minikube，启⽤Heapster addon后，即可在Dashbo addon后，即可在Dashboard上看到各种资源的CPU占⽤等指标。然⽽，对 于 minikube 0.22.x ，在Dashboard上⽆法看到，可使⽤如下命令，直接查询Grafana监控界⾯： minikube addons open heapster 相关Issue：https://github.com/kubernetes/minikube/issues/2013 限制CPU分配 示例 cpu-request-limit

但我们忽略了⼀个关键节点：开发阶段 微服务应⽤使⽤ Kubernetes ⼯作负载封装后，解决了开发过程应⽤的快速启动问题，开发⼈员只需要在本地 安装单节点的 Kubernetes 集群，例如 Minikube、Kind 等即可快速启动微服务应⽤。 但对于开发⼈员来说，原来单体应⽤的开发体验变得不复存在，由于应⽤很难在 Docker 容器之外运⾏，所以 每次代码修改，都需要经历以下步骤： 执⾏ docker 的集群，运⾏以下命令来快速初始化： Nocalhost - 重新定义云原⽣开发环境.md 2021/1/20 6 / 7 nhctl init -n nocalhost -p 7000 对于 Minikube、Kind、K3S、MicroK8s 等，运⾏以下命令： nhctl init -n nocalhost -t nodeport --set mariadb.primary.persistence
