部署

kubectl apply -f configmap.yaml
kubectl apply -f statefulset.yaml

创建inlfuxdb账号及数据库

CREATE DATABASE "prometheus";
CREATE USER admin WITH PASSWORD '1234356' WITH ALL PRIVILEGES;
alter retention policy "autogen" on "prometheus" duration 15d default;

修改configmap.yaml文件，开启认证

...   
 [http]
      enabled = true
      bind-address = ":8086"
      auth-enabled = true #false修改为true,开启认证
...

重启influxdb
