Dapr + .NET Core实战（十-终篇）K8S运行Dapr

为了实现在k8s上安装Dapr，Dapr需要部署dapr-sidecar-injector、dapr-operator、dapr-placement和dapr-sentry服务。 

dapr-operator: 管理组件(state stores, pub/subs, etc.)

dapr-sidecar-injector: 将 Dapr 注入  pods，并添加环境变量 DAPR_HTTP_PORT 和 DAPR_GRPC_PORT，以使用户定义的应用程序能够轻松地与 Dapr Sidecar通信，而无需硬编码 Dapr 端口值。

dapr-placement: 将 actor 实例映射到 pods。

dapr-sentry: 管理服务之间的mTLS并作为证书颁发机构。 

2.安装K8s集群

通常使用以下方法本地安装的K8S集群

k8s-for-docker-desktop

kubeadm

我本地已经安装好了这两种，这次使用kubeadm 1.20版本演示dapr

 3.将Frontend和Backend build成docker Image

vs中分别右击Frontend和Backend，添加Docker支持，即可生成对应的Dockerfile，修改暴露端口

#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.
