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

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

config.lua // 配置数据库访问

local config = require("lapis.config")
config("development", {
