1、Loki 部署

本文不过多介绍，请参考官网：Install the monolithic Helm chart | Grafana Loki documentation

loki:
  auth_enabled: false
  commonConfig:
    replication_factor: 1
  storage:
    type: 'filesystem' #you storage name
singleBinary:
  replicas: 1

helm upgrade --values values.yaml loki --namespace=phx-sidecar grafana/loki

 2、Promtail
