Question

到目前为止，我正在尝试使用istio 1.1.5最新版本在GKE Cluster中启动spring boot micro服务。它引发错误，并且pod永不旋转。如果我在Kubernetes引擎中将其作为单独的服务运行，则它可以完美运行，但与isito一起使用时，它将不起作用。使用istio的目的是托管多个微服务并使用istio提供的功能。这是我的yaml文件：

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: revenue  
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: revenue-serv
        tier: backend
        track: stable
    spec:
      containers:
        - name: backend
          image: "gcr.io/finacials/revenue-serv:latest"
          imagePullPolicy: Always
          ports:
          - containerPort: 8081
          livenessProbe:
              httpGet:
                path: /
                port: 8081
              initialDelaySeconds: 15
              timeoutSeconds: 30 
          readinessProbe:
              httpGet:
                path: /
                port: 8081
              initialDelaySeconds: 15
              timeoutSeconds: 30

感谢您的宝贵反馈。

我发现了问题。我删除了readynessProbe和livenessProbe，并创建了入口网关和虚拟服务。奏效了。

部署和服务：
