Nginx入口控制器无法运行

Question

我试图在没有负载均衡器和云提供商的情况下在我自己的服务器上部署nginx入口控制器。我做了以下步骤：

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

然后，我为这个nginx-ingress创建了一个名为serviceAccount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，当我获得部署状态时，它会告诉我：

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/不运行。

这里出了什么问题，如何获取失败部署的日志？

Answer 1

造成此问题的原因是缺少服务帐户。

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

使用下面的命令，您可以创建SA

kubectl create serviceaccount my-service-account

关于更多细节，K8s-服务-帐户

Answer 2

从服务清单中删除以下条目

externalTrafficPolicy: Local

  externalIPs:
    - my-external-node-ip
