k8s安装之nginx.yaml

这里两个nginx。一个是用来测试最简单的集群的。

另一个是用来作grafana,prometheus,dashboard前端安全展示的。

 

简单版

spec:
  replicas: 1
  selector:
    matchLabels:
      name: nginx
  template:

    spec:
      containers:

          image: harbor.xxx.cn/official_hub/nginx:1.13-alpine
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 80

apiVersion: v1
