Dapr+Net6+K8S最小原型项目架构和实现-12-将Dapr项目部署到K8S集群

1. 回顾

上一章，我们使用AspNetCore6.0编写了Dapr项目：

这一章，我们将Dapr项目部署到K8S集群。

2. 编写Dapr项目yaml部署文件

apiVersion: v1
kind: Namespace
metadata:
  name: dapr-demo
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: service01
  namespace: dapr-demo
  labels:
    app: service01
spec:
  replicas: 2
  selector:
    matchLabels:
      app: service01
  template:

      annotations:
        dapr.io/enabled: "true"
        dapr.io/app-id: "service01"
        dapr.io/app-port: "80"
        dapr.io/sidecar-liveness-probe-delay-seconds: "10"
        dapr.io/sidecar-readiness-probe-delay-seconds: "10"
        dapr.io/log-as-json: "true"
    spec:
      containers:
        - name: service01
          image: docker.io/k8schina/service01:v1
          ports:
            - containerPort: 80
          imagePullPolicy: Always
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: service02
  namespace: dapr-demo
  labels:
    app: service02
spec:
  replicas: 1
  selector:
    matchLabels:
      app: service02
  template:

      annotations:

        dapr.io/app-port: "80"
        dapr.io/sidecar-liveness-probe-delay-seconds: "10"
        dapr.io/sidecar-readiness-probe-delay-seconds: "10"
    spec:
      containers:
        - name: service02
          image: docker.io/k8schina/service02:v1
          ports:
            - containerPort: 80
          imagePullPolicy: Always
---
apiVersion: v1
kind: Service
metadata:
  name: service02
  namespace: dapr-demo
spec:
  type: NodePort
  selector:
    app: service02
  ports:
    - port: 80
      targetPort: 80
      nodePort: 30006

3. 将DarpDemo项目部署到K8S集群

3.1. 部署

kubectl apply -f http://k8schina.corecore.cn/DaprDemo.yaml

3.2. 验证docker镜像

docker images | grep service

• 可能被调度到slave节点下载

3.3. 验证pod

kubectl get pods -n dapr-demo

• 每个pod有两个container，一个是service，一个是dapr sidecar 

3.4. 验证 service

kubectl get svc -n dapr-demo

4. 配置反向代理

• 反向代理到DaprDemo的K8S服务

vi /usr/local/nginx/conf/nginx.conf

server {
        listen       80;
        server_name  app.corecore.cn;
 
        location / {
            proxy_pass http://localhost:30006;
        }
}

server {
        listen       80;
        server_name  www.corecore.cn;
 
        location / {
            root html;
            index index.html index.htm;
        }
}

• 重启nginx

/usr/local/nginx/sbin/nginx -s reload

5. 公网访问我们的微服务

http://app.corecore.cn/api/hello

​

​  

• 可以看到负载均衡效果，两次访问，被路由到了不同的pod
