標籤 lapis 項目添加 prometheus 監控简体版

原文原文鏈接

lapis 是基於openresty 擴展的，因此直接將支持prometheus的模塊構建進openresty 就能夠了
我使用的是nginx-module-vts 模塊html

環境準備

我已經構建好了支持的基礎鏡像，能夠直接配置便可，具體的能夠看下面的參考資料nginx

docker-compose 文件

version: "3"
services:
 api:
   build: ./
   ports:
   - "8080:8080"
   volumes:
   - "./web:/web"

dockerfile

FROM dalongrong/lapis-1.7.0:metrics
ENTRYPOINT [ "lapis","server" ]

dalongrong/lapis-1.7.0:metrics 鏡像

FROM dalongrong/openresty-nginx-module-vts:fat
RUN apk add openssl-dev
WORKDIR /web
RUN /usr/local/openresty/luajit/bin/luarocks install lapis

dalongrong/openresty-nginx-module-vts:fat 鏡像
能夠參考https://github.com/rongfengliang/openresty-nginx-module-vts
nginx.conf 配置vts 支持
主要是web 中nginx.conf 模版的添加

    }

        vhost_traffic_status_display_format html;
    }
    location /static/ {
      alias static/;
    }

    location /favicon.ico {
      alias static/favicon.ico;
    }
  }
