使用 loki grafana 分析nginx 请求日志
loki 是类似prometheus 的log 可视化展示、收集系统，已经集成在grafana 6.0 版本中了
说明： 测试环境使用了docker-compose 运行
环境准备
- docker-compose 文件
version: "3"services: nginx: build: ./ ports: - "8090:80" volumes: - $PWD:/etc/promtail loki: image: grafana/loki:master ports: - "3100:3100" volumes: - $PWD:/etc/loki command: -config.file=/etc/loki/loki-local-config.yaml promtail: image: grafana/promtail:make-images-static-26a87c9 volumes: - $PWD:/etc/promtail - ./log:/var/log command: -config.file=/etc/promtail/promtail-docker-config.yaml grafana: image: grafana/grafana:master ports: - "3000:3000" environment: - "GF_EXPLORE_ENABLED=true"- 配置说明
nginx loki 配置，主要是使用容器运行多个应用
dockerfile
FROM grafana/promtail:make-images-static-26a87c9 as builderFROM openresty/openresty:alpineENV TINI_VERSION v0.18.0RUN apk add --update \ && apk add --no-cache tiniADD entrypoint.sh /entrypoint.shADD promtail.sh /promtail.shCOPY nginx.conf usr/local/openresty/nginx/conf/COPY --from=builder /usr/bin/promtail /usr/bin/EXPOSE 80ENTRYPOINT ["/sbin/tini","-s", "--", "/entrypoint.sh"]entrypoint.sh:
#!/bin/shsh promtail.shexec /usr/local/openresty/bin/openresty -g "daemon off;"promtail.sh:
后台方式运行，配置通过数据卷挂载
#!/bin/shnohup /usr/bin/promtail -config.file=/etc/promtail/promtail-docker-config2.yaml & nginx log 配置：
很简单，就是基本的配置

- 构建包含agent 的 nginx
docker-compose build- 启动
docker-compose up -d- 测试
