我已经成功地在几个容器化应用程序中使用了Traefik，并且我对使用LetsEncrypt的本机SSL支持感到满意(非常感谢Traefik团队)。然而，具体来说，要运行Odoo(开源ERP/CRM)，我在后台和浏览器中通过javascript日志得到一个异常:Exception: bus.Bus unavailable+调用栈在这里不重要。显然，这个异常的根本原因是Traefik没有代理到URL/longpolling的请求，当odoo.conf文件中的参数workers > 1时。
Odoo服务器公开两个不同的端口:
- 8069:对webapp的正常请求
- 7082:
/longpolling下的聊天服务使用
我做了一个GitHub仓库，解释如何重现这个"bug";(我不知道这是一个错误，还是我不知道如何正确使用它)。
作为参考，我还添加了一个不使用SSL的nginx.conf文件(只是为了简单起见)。
这是我用来运行Odoo + Traefik的docker-compose.yml:

- traefik.http.middlewares.sslheader.headers.customrequestheaders.X-Forwarded-Proto=https
我找到的最接近的解决方案是在Traefik论坛上的这个问题，建议包括下面的行(我尝试过，但仍然不起作用):traefik.http.middlewares.sslheader.headers.customrequestheaders.X-Forwarded-Proto = https
我可能错过了什么，但我想不出来。
想法吗?
正确的Odoo url路径为/longpolling。检查你的Traefik和Odoo配置是否使用longpolling，而不是longpooling，例如，Traefik的Odoo容器标签…PathPrefix('/longpooling')"→…PathPrefix('/longpolling')".
