修改

修改三个地方:

  1. hostNetwork:使用宿主机的网络;
  2. nodeSelector:添加标签选择器;
  3. DaemonSet:修改 DeploymentDaemonSet
  4. 删除原有名为 ingress-nginx-controllerService

如下:

apiVersion: apps/v1
kind: DaemonSet  # 这里把 Deployment 改成 DaemonSet
metadata:
  labels:
    ...
  name: ingress-nginx-controller
  namespace: ingress-nginx
spec:
  minReadySeconds: 0
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      app.kubernetes.io/component: controller
      app.kubernetes.io/instance: ingress-nginx
      app.kubernetes.io/name: ingress-nginx
  template:
    metadata:
      labels:
        app.kubernetes.io/component: controller
        app.kubernetes.io/instance: ingress-nginx
        app.kubernetes.io/name: ingress-nginx
    spec:
      hostNetwork: true  #这里加一句
      nodeSelector:
        kubernetes.io/os: linux
        hasIngress: "true"  # 在存在这个标签的 node 上部署
      containers:
      - args:
        ...

部署

给节点打上标签,标识需要在该节点上运行 ingress controller:

kubectl label <node_name> hasIngress="true"

部署修改后的 Yaml:

kubectl create -f deploy.yaml

附加

附一份当前(2022.11.26)最新的、已经修改好的、且修改镜像源为阿里云 acr 的 yaml:
