Grafana匿名登录Kubernetes设置

在Kubernetes中，通过yaml文件安装Grafana。要实现匿名登录查看Dashboard，则需要在`spec.template.spec.containers[]下面添加如下内容：

env:
- name: GF_AUTH_ANONYMOUS_ENABLED
  value: "true"
- name: GF_AUTH_ANONYMOUS_ORG_ROLE
  value: Viewer

部分内容如下：

spec:
  replicas: 1
  selector:
    matchLabels:
      app: grafana
  template:
    metadata:
      labels:
        app: grafana
    spec:

        name: grafana
        ports:
        - containerPort: 3000
          name: http
        readinessProbe:
          httpGet:
            path: /api/health
            port: http
        resources:
          limits:
            cpu: 200m
            memory: 200Mi
          requests:
            cpu: 100m
            memory: 100Mi
        env:
        - name: GF_AUTH_ANONYMOUS_ENABLED
