lapis docker 运行说明

1. lapis docker 镜像制作

因为openresty 新版本一个json 库的问题，我们使用的是 openresty:1.11.2.1 基础镜像

FROM openresty/openresty:1.11.2.1-centos
RUN yum install -y openssl-devel
RUN /usr/local/openresty/luajit/bin/luarocks install luaossl && \
    /usr/local/openresty/luajit/bin/luarocks install lapis
ENV PATH=$PATH:/usr/local/openresty/luajit/bin:/usr/local/openresty/nginx/sbin:/usr/local/openresty/bin

2. 基本项目

备注：基础镜像可以使用上面构建的，同时可以使已经构建好的

docker pull dalongrong/openrestydemogithub:lapis

3. 项目代码说明

主要是app.lua 以及config.lua

app.lua

local lapis = require("lapis")
local db = require("lapis.db")
local app = lapis.Application()
local json = require("cjson");
app:get("/", function()
  return "Welcome to Lapis " .. require("lapis.version")
end)
app:get("/user", function()
  -- local res = db.query("SELECT * FROM userdemo")
  -- return json.encode(res)
  local res = db.query("SELECT * FROM userdemo")
  return { json= res}

end)
return app

config.lua // 配置数据库访问

local config = require("lapis.config")
config("development", {
  mysql = {
    host = "mydb",--change to you database url
    user = "root",
    password = "dalongrong",
    database = "userapp"
  }
})

Dockerfile
