Kubernetes上的 Dapr 概述
Kubernetes上的 Dapr
Dapr can be configured to run on any supported versions of Kubernetes. 为了实现这一目标,Dapr首先部署了dapr-sidecar-injector
、dapr-operator
、dapr-placement
和dapr-sentry
Kubernetes服务。 这些都提供了一流的集成,使Dapr的应用运行变得简单。
- dapr-operator: Manages component updates and Kubernetes services endpoints for Dapr (state stores, pub/subs, etc.)
- dapr-sidecar-injector: 将 Dapr 注入 annotated deployment 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 通信,而无需硬编码 Dapr 端口值。 - dapr-placement: Used for actors only. 创建映射表,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。 For more information read the security overview.
在 Kubernetes 集群上部署 Dapr
Read this guide to learn how to deploy Dapr to your Kubernetes cluster.
将 Dapr 添加到 Kubernetes deployment
在 Kubernetes 集群中部署和运行启用 Dapr 的应用程序非常简单,只需向 deployment 方案添加一些注解。 要给您的服务提供一个 id
和 port
已知的 Dapr, 通过配置进行追踪并启动 Dapr sidecar 容器, 你要像这样注释你的 Kubernetes deployment。 For more information check dapr annotations
annotations:
dapr.io/enabled: "true"
dapr.io/app-id: "nodeapp"
dapr.io/app-port: "3000"
dapr.io/config: "tracing"
