无法应用 Nginx 入口控制器

Question

我在本地系统中有 3 个 VMS 运行，每个 1 个主服务器，2 个节点。我已经安装了 weave CNI 网络。我正在尝试使用

安装 Nginx 入口控制器

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.44.0/deploy/static/provider/cloud/deploy.yaml

但是我无法创建它。我对 AWS Ec2 实例进行了同样的尝试。它总是崩溃我看过描述在 admission-create pod MountVolume.SetUp failed for volume "kube-api-access-kdhpc" : object "ingress-nginx"/"kube-root-ca.crt" not registered

中收到此错误

并且 admission-patch,controller pod 不断重启控制器 pod 输出我在这里有点震惊。我也尝试过使用 flannel cni，结果是一样的。任何建议表示赞赏。

Answer 1

我认为你应该使用这个（用于裸机）

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-0.31.1/deploy/static/provider/baremetal/deploy.yaml

试试这些步骤，这些配置很适合我。

入口控制器

apiVersion: apps/v1
kind: Deployment
metadata:
  name: ingress-controller
  namespace: ingress-space
spec:
  replicas: 1
  selector:
    matchLabels:
      name: nginx-ingress
  strategy:
    rollingUpdate:
      maxSurge: 25%
      maxUnavailable: 25%
    type: RollingUpdate
  template:
    metadata:
      labels:
        name: nginx-ingress
    spec:
      containers:
      - args:
        - /nginx-ingress-controller
        - --configmap=$(POD_NAMESPACE)/nginx-configuration
        - --default-backend-service=app-space/default-http-backend
        env:
        - name: POD_NAME
          valueFrom:
            fieldRef:
              apiVersion: v1
              fieldPath: metadata.name
        - name: POD_NAMESPACE
          valueFrom:
            fieldRef:
              apiVersion: v1
              fieldPath: metadata.namespace
        image: quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.21.0
        imagePullPolicy: IfNotPresent
        name: nginx-ingress-controller
        ports:
        - containerPort: 80
          name: http
          protocol: TCP
        - containerPort: 443
          name: https
          protocol: TCP
      restartPolicy: Always
      serviceAccount: ingress-serviceaccount
      serviceAccountName: ingress-serviceaccount
      terminationGracePeriodSeconds: 30

入口服务

根据您的配置应用此 NodePort 或 LoadBalancer：

apiVersion: v1
kind: Service
metadata:
  name: ingress
  namespace: ingress-space
spec:
  ports:
  - name: http
    nodePort: 30080
    port: 80
    protocol: TCP
    targetPort: 80
  - name: https
    nodePort: 31640
    port: 443
    protocol: TCP
    targetPort: 443
  selector:
    name: nginx-ingress
  type: NodePort

Ingress 的角色

您需要为入口创建一个服务帐户，您选择的任何名称，应用这些 rbac 集群角色和集群角色绑定

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: ingress-role
rules:
- apiGroups:
  - ""
  resources:
  - services
  - endpoints
  verbs:
  - get
  - list
  - watch
- apiGroups:
  - ""
  resources:
  - secrets
  verbs:
  - get
  - list
  - watch
- apiGroups:
  - ""
  resources:
  - configmaps
  verbs:
  - get
  - list
  - watch
  - update
  - create
- apiGroups:
  - ""
  resources:
  - pods
  verbs:

  resources:

apiVersion: rbac.authorization.k8s.io/v1

您的入口源已准备好安装，请参阅https://kubernetes.io/docs/concepts/services-networking/ingress/并应用入口资源
