我在 grpc.mydomain.com 上使用 LetsEncrypt 在 traefik 上启动并运行了一项服务。但是,由于 CORS 的一些问题( https://github.com/containous/traefik/issues/4210),traefik 不支持路由 grpc-web 请求。Envoy 似乎是与 grpc-web 一起使用的 traefik 的替代品,但我不想重新配置所有内容。
如果我将特使放在 envoy.mydomain.com 上,那么它实际上首先会命中 traefik,而 traefik 无法将 grpc-web 请求路由到特使。所以这行不通。
如果我将特使放在 traefik 之外(mydomain.com:9091),那么特使就没有 traefik 所具有的 TLS 支持。
我需要将所有东西都切换到特使吗?有没有我没有考虑过的替代方案?欢迎任何指导:)
当前 Traefik 设置:

我还尝试设置这些以修复 CORS 错误,但无济于事。
