问题 Im trying to set up a local cluster using VM and minikube, as Id been reading its only possible to use it for local purposes, but id like to join a secondary machine, and im searching a way to create the join and hash. 回答1: You can easily do it in case your minikube machine is using VirtualBox. Start the minikube: $ minikube start --vm-driver="virtualbox" Check the versions of kubeadm, kubelet and kubectl in minikube and print join command: $ kubectl version $ minikube ssh $ kubelet --version

作者 | 易立 阿里云资深技术专家 containerd 是一个开源的行业标准容器运行时，关注于简单、稳定和可移植，同时支持 Linux 和 Windows。 2016 年 12 月 14 日，Docker 公司宣布将 Docker Engine 的核心组件 containerd 捐赠到一个新的开源社区独立发展和运营。阿里云、AWS、 Google、IBM 和 Microsoft 作为初始成员，共同建设 containerd 社区； 2017 年 3 月，Docker 将 containerd 捐献给 CNCF（云原生计算基金会）。containerd 得到了快速的发展和广泛的支持； Docker 引擎已经将 containerd 作为容器生命周期管理的基础，Kubernetes 也在 2018 年 5 月，正式支持 containerd 作为容器运行时管理器； 2019 年 2 月，CNCF 宣布 containerd 毕业，成为生产可用的项目。 containerd 从 1.1 版本开始就已经内置了 Container Runtime Interface (CRI) 支持，进一步简化了对 Kubernetes 的支持。其架构图如下： 在 Kubernetes 场景下，containerd 与完整 Docker Engine 相比，具有更少的资源占用和更快的启动速度。 图片来源：

helm简介 Helm 可以理解为 Kubernetes 的包管理工具，可以方便地发现、共享和使用为Kubernetes构建的应用。 Helm 采用客户端/服务器架构，有如下 组件 组成： Helm CLI 是 Helm 客户端，可以在本地执行 Tiller 是服务器端组件，在 Kubernetes 群集上运行，并管理 Kubernetes 应用程序的生命周期 Repository 是 Chart 仓库，Helm客户端通过HTTP协议来访问仓库中Chart的索引文件和压缩包。 1.Helm的三个基本概念 Chart：Helm应用（package），包括该应用的所有Kubernetes manifest模版，类似于YUM RPM或Apt dpkg文件 Repository：Helm package存储仓库 Release：chart的部署实例，每个chart可以部署一个或多个release 2.Helm工作原理 Helm把Kubernetes资源(比如deployments、services或 ingress等) 打包到一个chart中，而chart被保存到chart仓库。通过chart仓库可用来存储和分享chart。Helm使发布可配置，支持发布应用配置的版本管理，简化了Kubernetes部署应用的版本控制、打包、发布、删除、更新等操作。 Helm包括两个部分

Minikube expose MySQL running on localhost as service

I have minikube version v0.17.1 running on my machine. I want to simulate the environment I will have in AWS, where my MySQL instance will be outside of my Kubernetes cluster. Basically, how can I expose my local MySQL instance running on my machine to the Kubernetes cluster running via minikube? Crazykev Kubernetes allows you to create a service without selector, and cluster will not create related endpoint for this service, this feature is usually used to proxy a legacy component or an outside component. Create a service without selector apiVersion: v1 kind: Service metadata: name: my
