Kubernets traefik代理ws wss应用

对你无可奈何 • 2023-01-02 • 云技术社区 • 445 阅读

背景：

团队要发布一组应用，springboot开发的ws应用。然后需要对外。支持ws wss协议。jenkins写完pipeline发布任务。记得过去没有上容器的时候都是用的腾讯云的cls 挂证书映射cvm端口。我现在的网络环境是这样的：Kubernetes 1.20.5 安装traefik在腾讯云下的实践（当然了本次的环境是跑在tke1.20.6上面的，都是按照上面实例搭建的---除了我新建了一个namespace traefik，并将traefik应用都安装在了这个命名空间内！这样做的原因是tke的kebe-system下的pod太多了！我有强迫症）

部署与分析过程：

1. 关于我的应用：

应用的部署方式是statefulset，如下：

cat <<EOF >  xxx-gateway.yaml
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: xxx-gateway
spec:
  serviceName: xxx-gateway
  replicas: 1
  selector:
    matchLabels:
      app: xxx-gateway
  template:
    metadata:
      labels:
        app: xxx-gateway
    spec:
      containers:
        - name: xxx-gateway
          image: ccr.ccs.tencentyun.com/xxx-master/xxx-gateway:202107151002
          env:
          - name: SPRING_PROFILES_ACTIVE
            value: "official"
          - name: SPRING_APPLICATION_JSON
            valueFrom:
             configMapKeyRef:
              name: spring-config
              key: dev-config.json
          ports:
            - containerPort: 8443
          resources:
            requests:
              memory: "512M"
              cpu: "500m"
            limits:
              memory: "512M"
              cpu: "500m" 
      imagePullSecrets:                                              
        - name: tencent
---

apiVersion: v1
kind: Service
metadata:
  name: xxx-gateway
  labels:
    app: xxx-gateway
spec:
  ports:
  - port: 8443
  selector:
    app: xxx-gateway
  clusterIP: None
EOF

kubectl apply -f xxx-gateway.yaml -n official

偷个懒直接copy了一个其他应用的 ingress yaml修改了一下,如下：

cat <<EOF >  gateway-0-ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: layaverse-gateway-0-http
  namespace: official
  annotations:
    kubernetes.io/ingress.class: traefik  
    traefik.ingress.kubernetes.io/router.entrypoints: web
spec:
  rules:
  - host: xxx-gateway-0.xxx.com
    http:
      paths:
      - pathType: Prefix
        path: /
        backend:
          service:
            name: xxx-gateway 
            port: 
              number: 8443
EOF
