K8S版本：v1.8.2
Grafana及loki都安装好了，但是promtail安装后报错：
level=warn ts=2022-02-16T08:45:02.852189747Z caller=logging.go:71 msg="GET /ready (500) 165.959µs Response: \"Not ready: Unable to find any logs to tail. Please verify permissions, volumes, scrape_config, etc.\\n\" ws: false; Accept-Encoding: gzip; Connection: close; User-Agent: kube-probe/1.8; "
检查过后是因为/run/promtail/positions.yaml未写入数据。检查了一下挂载的docker及pods的路径，里面都是有日志数据的。
以下是我的配置文件，求解答，万分感谢：
