Traefik

Question

我的配置是一个简单的 Docker Swarm（在 Docker for Windows 上），带有一个 Treafik 容器和一个非常简单的 Spring Boot 'echo' 容器.

我想将 'localhost/traefik' 的浏览器请求转发到 Traefik 仪表板，并将 'localhost/echo/something' 转发到一个简单的 Sprint Boot echo 应用程序。

预计工作：

localhost/treafik => gives a "Gateway timeout"
localhost/echo/something => gives a "Gateway timeout"

预计不会工作，但会绕过 Traefik（错误地）：

localhost:8080 => shows the Traefik dashboard
localhost:8082/echo/something => { "status":"something" }

如何改进 docker-compose.yml 文件以获得预期的结果？这与 'networking' 有关系吗？创建任何网络时，即使是覆盖，也会给出错误消息。

第一个问题是网络问题。解决了，多亏了聪明的吉姆。

另一个问题是我使用了错误的端口号。要从前端“/echo”路由到后端，不使用 'ports' 部分。我可以直接路由到 slackbot 应用程序的公开端口！

查看端口配置：只有 80 个可用。
