添加后重启docker-compose容器

docker-compose up -d

重启后在office-preview/shared目录添加office_convertor_settings.py，内容如下

# -*- coding:utf-8 -*-

#和 seafile 的 seahub_settings.py 里的 SECRET_KEY 保持一致
SECRET_KEY = "b'+lr$^+j9m2(o!tp$*0q-&5u4^x%dw10662@p67c51mc0y$tnlb'"  

WORKERS = 10                   # worker 数
OUTPUT_DIR = '/shared/output'  # 输出目录，容器内目录
PORT = 8089                    # 服务端口，容器内端口，非映射到外部的端口

并修改权限为755

chmod 755 office_convertor_settings.py

在seafile容器中增加office预览配置

进入seafile容器

docker exec -it seafile bash
cd conf

编辑conf目录下的seahub_settings.py，添加如下配置

OFFICE_CONVERTOR_ROOT = 'http://seafile-office-preview:8089'

http后面跟office的容器名即可，即使重启docker-compose导致容器漂移也不用重配ip

最后上系统配置界面看上传下载地址是否配好。

 配好之后就能正常工作了，2M以内的office文件都能预览，超过了必须下载
