Docker 安装 (本次未测试Docker)
https://hub.docker.com/r/grafana/loki
Loki Docker Image
Running Docker
- docker run -d --name=loki -p 3100:3100 grafana/loki
- To persist data in a docker volume named loki-data:
- docker run -d --name=loki --mount source=loki-data,target=/loki -p 3100:3100 grafana/loki
- To run using a custom config file:
- docker run -d --name=loki --mount type=bind,source="path to loki-config.yaml",target=/etc/loki/local-config.yaml -p 3100:3100 grafana/loki
- In most cases you should specify a tagged release version for running, the above examples all use the implied :latest tag:
-
docker run -d --name=loki -p 3100:3100 grafana/loki:1.4.1

# By default, Loki will send anonymous, but uniquely-identifiable usage and configuration
# analytics to Grafana Labs. These statistics are sent to https://stats.grafana.org/
#
# Statistics help us better understand how Loki is used, and they show us performance
# levels for most users. This helps us prioritize features and documentation.
# For more information on what's sent, look at
# https://github.com/grafana/loki/blob/main/pkg/usagestats/stats.go
# Refer to the buildReport method to see what goes into a report.

# If you would like to disable reporting, uncomment the following lines:
