参考 github 上的一个 issue 以及代码，修改为下面这样配置 docker-compose.yml 文件可以 (本地 ubuntu 上 docker-compose 成功运行)：

version: '3'
services:
  siyuan:
    image: b3log/siyuan
    container_name: siyuanNote
    restart: always
    ports: 
      - 6806:6806
    command: [--accessAuthCode=123456,--lang=zh_CN]
    volumes:
      - siyuan:/siyuan/workspace
    user: 1000:1000
volumes:
  siyuan:

项目代码中，参数配置在 kernel/util/working.go 文件，第 62 - 69 行, 代码如下：

	workspacePath := flag.String("workspace", "", "dir path of the workspace, default to ~/Documents/SiYuan/")
	wdPath := flag.String("wd", WorkingDir, "working directory of SiYuan")
	port := flag.String("port", "0", "port of the HTTP server")
	readOnly := flag.String("readonly", "false", "read-only mode")
	accessAuthCode := flag.String("accessAuthCode", "", "access auth code")
	ssl := flag.Bool("ssl", false, "for https and wss")
	lang := flag.String("lang", "", "zh_CN/zh_CHT/en_US/fr_FR/es_ES")
	mode := flag.String("mode", "prod", "dev/prod")

昨天部署的时候，没有注意授权码的问题。不过，刚 windows 上试了一下 docker-compose 部署，但是访问网页，并没有让输入授权码，不知道你那边部署完之后是否成功了？
