Kubernetes部署elasticsearch-head

在之前已经部署好了elasticsearch集群了，下面开始部署es-head。es-head是一个nodejs项目，所以我们使用deployment部署就可以了。

在之前的configmap中我们已经加入了 http.cors.enabled: true 和 http.cors.allow-origin: “*”，处理跨域拒绝访问问题

创建deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: es-head
  namespace: log-system
spec:
  replicas: 2
  selector:
    matchLabels:
      app: es-head
  template:
    metadata:
      labels:
        app: es-head
    spec:
      containers:
        - name: es-head
          image: mobz/elasticsearch-head:5
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 9100

创建service

apiVersion: v1
kind: Service
metadata:
  name: es-head
  namespace: log-system
spec:
  type: NodePort
  selector:
    app: es-head
  ports:
    - port: 9100
      targetPort: 9100

测试es连接

通过node ip:nodepod访问es-head页面,然后输入node ip + es-out的svc nodeport 连接即可
