Nginx入口控制器無法運行

Question

我正在嘗試在沒有負載平衡器和雲提供程序的情況下在自己的服務器中部署Nginx-ingress控制器。 我做了以下步驟：

apiVersion: v1
kind: Namespace
metadata:
  name: ingress-nginx

然后，我為serviceAccount創建了一個名為nginx-ingress的集群角色。
我的nginx-controller-service.yaml ：

kind: Service
apiVersion: v1
metadata:
  name: ingress-nginx
  namespace: ingress-nginx
  labels:
    app: ingress-nginx
spec:
  externalTrafficPolicy: Local
  type: NodePort
  selector:
    app: ingress-nginx
  ports:
  - name: http
    port: 80
    targetPort: http
  - name: https
    port: 443
    targetPort: https
  externalIPs:
    - my-external-node-ip

和nginx-ingress-controller.yaml ：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: nginx-ingress-controller
  namespace: ingress-nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: ingress-nginx
  template:
    metadata:
      labels:
        app: ingress-nginx
      annotations:
        prometheus.io/port: '10254'
        prometheus.io/scrape: 'true'
    spec:
      serviceAccountName: nginx-ingress
      containers:
        - name: nginx-ingress-controller
          image: quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.9.0-beta.17
          args:
            - /nginx-ingress-controller
            - --default-backend-service=$(POD_NAMESPACE)/default-http-backend
          env:
            - name: POD_NAME
              valueFrom:
                fieldRef:
                  fieldPath: metadata.name
            - name: POD_NAMESPACE
              valueFrom:
                fieldRef:
                  fieldPath: metadata.namespace
          ports:
          - name: http
            containerPort: 80
          - name: https
            containerPort: 443
          livenessProbe:
            failureThreshold: 3
            httpGet:
              path: /healthz
              port: 10254
              scheme: HTTP
            initialDelaySeconds: 10
            periodSeconds: 10
            successThreshold: 1
            timeoutSeconds: 1
          readinessProbe:
            failureThreshold: 3
            httpGet:
              path: /healthz
              port: 10254
              scheme: HTTP
            periodSeconds: 10
            successThreshold: 1
            timeoutSeconds: 1

但是，當我獲得部署狀態時，它向我顯示：

NAMESPACE       NAME                                       READY   UP-TO-DATE   AVAILABLE   AGE
ingress-nginx   deployment.apps/default-http-backend       1/1     1            1           17m
ingress-nginx   deployment.apps/nginx-ingress-controller   0/1     0            0           17m

控制器不可用/未運行。

這里出了什么問題，如何獲取失敗部署的日志？

Answer 1

該問題是由於缺少服務帳戶引起的。

58m Warning FailedCreate ReplicaSet Error creating: pods "nginx-ingress-controller-5b7f66f95f-" is forbidden: error looking up service account ingress-nginx/nginx-ingress: serviceaccount "nginx-ingress" not found

使用以下命令可以創建SA

kubectl create serviceaccount my-service-account

進一步了解k8s-service-account

Answer 2

從服務清單中刪除以下條目

externalTrafficPolicy: Local

  externalIPs:
    - my-external-node-ip
