Google Kubernetes Engine Ingress 后端服务不健康

Question

Kind Note: I have googled a lot and take a look too many questions related to this issue at Whosebug also but couldn't solve my issue, that's why don't mark this as duplicate, please!

我正在尝试在 Google Kubernetes Engine 上部署 2 个服务（一个是 Python flask，另一个是 NodeJS）。我已经为每个服务创建了两个 Kubernetes 部署，为每个 NodePort 类型的服务创建了两个 Kubernetes 服务。然后，我创建了一个 Ingress 并提到了我的 endpoints 但 Ingress 说一个后端服务是 UNHEALTHY.

这是我的部署 YAML 定义：

# Pyservice deployment
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: pyservice
  labels:
    app: pyservice
  namespace: default
spec:
  selector:
    matchLabels:
        app: pyservice
  template:
    metadata:
      labels:
        app: pyservice
    spec:
      containers:
      - name: pyservice
        image: docker.io/arycloud/docker_web_app:pyservice
        ports:
        - containerPort: 5000
      imagePullSecrets:
         - name: docksecret

# # Nodeservice deployment
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: nodeservice
  labels:
    app: nodeservice
  namespace: default
spec:
  selector:
    matchLabels:
        app: nodeservice
  template:
    metadata:
      labels:
        app: nodeservice
        tier: web
    spec:
      containers:
      - name: nodeservice
        image: docker.io/arycloud/docker_web_app:nodeservice
        ports:
        - containerPort: 8080
      imagePullSecrets:
         - name: docksecret

而且，这是我的服务和 Ingress YAML 定义：

# pyservcie service
kind: Service
apiVersion: v1
metadata:
  name: pyservice
spec:
  type: NodePort
  selector:
    app: pyservice
  ports:
  - protocol: TCP
    port: 5000
    nodePort: 30001
---

# nodeservcie service
kind: Service
apiVersion: v1
metadata:
  name: nodeservcie
spec:
  type: NodePort
  selector:
    app: nodeservcie
  ports:
  - protocol: TCP
    port: 8080
    nodePort: 30002
---

# Ingress

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: my-ingress
  namespace: default
  annotations:
    kubernetes.io/ingress.class: "gce"
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - http:
      paths:
      - path: /
        backend:
          serviceName: pyservice
          servicePort: 5000
      - path: /*
        backend:
          serviceName: pyservice
          servicePort: 5000
      - path: /node/svc/
        backend:
          serviceName: nodeservcie
          servicePort: 8080

pyservice 工作正常，但 nodeservice 显示为 UNHEALTHY 后端。这是一个截图：

即使我已经为所有 gke-.... 编辑了 Firewall Rules 并允许所有端口只是为了解决这个问题，但它仍然显示 nodeservice 的 UNHEALTHY 状态].

这是怎么回事？

提前致谢！

Answer 1

为什么要使用 GCE 入口 class 然后指定 nginx 重写注释？如果您还没有意识到，注解不会对 GCE 入口执行任何操作。

您还选择了 'nodeservcie' 而不是 'nodeservice'。
