我找到了一个tutorial来在Kubernetes集群中设置Selenium网格。在这里你可以找到一些例子：

• deployment.yaml：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: selenium-hub
spec:
  selector:
    matchLabels:
      app: selenium-hub
  strategy: 
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 0      
  template:
    metadata:
      labels:
        app: selenium-hub
    spec:
      containers:
      - name: selenium-hub
        image: selenium/hub:4.0.0
        resources:
          limits:
            memory: "128Mi"
            cpu: "500m"
        ports:
          - containerPort: 4444
        livenessProbe:
            httpGet:
              path: /wd/hub/status
              port: 4444
            initialDelaySeconds: 30
            timeoutSeconds: 5

• pod.yaml：

apiVersion: v1
kind: Pod
metadata:
  name: selenium-hub
  labels:
    name: hub
spec:
  containers:
  - name: selenium-hub
    image: selenium/hub:3.141.59-20200326
    resources:
      limits:
        memory: "128Mi"
        cpu: "500m"
    ports:
      - containerPort: 4444
    livenessProbe:
        httpGet:
          path: /wd/hub/status
          port: 4444
        initialDelaySeconds: 30
        timeoutSeconds: 5

• replication_controller.yaml：

apiVersion: v1
kind: ReplicationController
metadata:
  name: selenium-rep
spec:
  replicas: 2
  selector:
    app: selenium-chrome
  template:
    metadata:
      name: selenium-chrome
      labels:
        app: selenium-chrome
    spec:
      containers:
        - name: node-chrome
          image: selenium/node-chrome
          ports:
            - containerPort: 5555
          env:
            - name: HUB_HOST
              value: "selenium-srv"
            - name: HUB_PORT
              value: "4444"

• service.yaml

apiVersion: v1
kind: Service
metadata:
  name: selenium-srv
  labels:
    app: selenium-srv
spec:
  selector:
    app: selenium-hub
  ports:
  - port: 4444
    nodePort: 30001
  type: NodePort

本教程也记录在YouTube上。你可以在那里找到一个playlist，其中有几集与Kubernetes上的Selenium Grid相关。

现在回答可能有点晚了，但我们现在有了带舵图的 selenium 枢纽。只是发布这个链接，以防有人偶然发现同样的问题。谢谢你的贡献。
