openresty 使用 docker-compose 启动服务

1. pull docker 镜像

version: '3'
services:
  openresty_server:
    image: openresty/openresty:1.25.3.1
    command: [openresty, '-g', 'daemon off;']
    ports:
      - "${SERVER_PORT}:80"
    volumes:
      - ./nginx/conf.d:/etc/nginx/conf.d
      - ./nginx/nginx.conf:/usr/local/openresty/nginx/conf/nginx.conf
      - ./logs/nginx:/usr/local/openresty/nginx/logs
      - ./lualibs:/usr/local/openresty/nginx/lualibs
      - /etc/localtime:/etc/localtime
    user: root
    network_mode: bridge
    #working_dir: /app
    links:
      - openresty_kvrocks

  openresty_kvrocks:
    image: apache/kvrocks:2.8.0
    hostname: openresty_kvrocks
    command:
      - "--bind"
      - "0.0.0.0"
      - "--dir"
      - "/data/kvrocks"
      - "--workers"
      - "16"
    ports:
      - "${KVROCKS_PORT}:6666"
    volumes:
      - ./data/kvrocks:/data/kvrocks
    #environment:
    #  - ""
    user: root
    network_mode: bridge

1. 增加 nginx 的 gw.conf

    server 172.17.0.1:6930 weight=1;

  -- expose global as we expect
  resolver = resol.new("/etc/hosts")
}
#
server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;

        }
    }

    location / {

            --local resolver = require "local-resolver"

            local redis = require "resty.redis"

            local red = redis:new()

            local ok, err = red:connect(resolver:resolve("openresty_kvrocks"), 6666)
            if not ok then

                ngx.log(ngx.ERR, err)
                ngx.exit(ngx.HTTP_FORBIDDEN)
                return
            end

            local token = ngx.req.get_headers()['Token']
            if token == nil then
                token = "null"
            end

            local key = "resty:auth:access:token:" .. token
            local res, err = red:get(key)
            if not res then
                ngx.log(ngx.ERR, "get redis key failed: " .. key)
                ngx.exit(ngx.HTTP_FORBIDDEN)
                return
            end

            if res == ngx.null then
                ngx.log(ngx.ERR, "get redis key empty: " .. key)
                ngx.exit(ngx.HTTP_FORBIDDEN)
                return
            end

            --ngx.say(ngx.req.get_headers()['Token'])
        }
