influxdb2.0 beta填坑

Posted 2023-04-05

参考技术A 其中networks、label配置的是traefik反向代理的标签，将 influxdb.api.mydomain.com 这个域名代理到容器内部的9999端口，可以去除，但是要做9999的端口映射，用于访问influxdb。如果需要进行数据持久化，可以将容器内/root/.influxdbv2挂载到宿主机，参考 官方建议k8s配置文件 。

默认在9999端口提供webUI以及API服务，安装成功后直接访问 http://localhost:9999 ,可以在前面配置反向代理，如traefik、nginx等，但是注意必须要代理在根路径下，否则无法加载webUI的静态文件。相关 issue

在2.0版本升级后，数据操作的api都改为restful的webAPI，改变很大，所以Python的SDK也重做了，区别于1.x版本。
对写入数据的格式也有比较大的改变。
