环境准备

docker-compose

version: "3"
services:
  api:
   build: ./
   ports:
   - "8080:8080"
   volumes:
   - "./web:/web"
  g:
    image: grafana/grafana
    ports:
    - "3000:3000"
  p:
    image: prom/prometheus
    volumes:
    - "./prometheus.yml:/etc/prometheus/prometheus.yml"
    ports:
    - "9090:9090"

prometheus 配置
prometheus.yml 文件

scrape_configs:
  - job_name: nginx
    metrics_path: /status/format/prometheus
    static_configs:
      - targets: ['api:8080']

dockerfile
基本项目，使用数据卷挂载

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

添加几个测试路由
web/app.lua 文件，很简单都是get 方法

local lapis = require("lapis")
local app = lapis.Application()

app:get("/", function()
  return "Welcome to Lapis dalongrong " .. require("lapis.version")
end)

app:get("/users", function()
  return "users" .. require("lapis.version")
end)

app:get("/apps", function()
  return "apps" .. require("lapis.version")
end)


app:get("/mobiles", function()
  return "mobiles" .. require("lapis.version")
end)


app:get("/paas", function()
  return "paas " .. require("lapis.version")
end)
app:get("/saas", function()
  return "saas " .. require("lapis.version")
end)

return app
