使用 docker 镜像在 Azure 上部署 Spring Eureka Service Registry

Question

我创建了一个 Docker 映像并通过 docker hub 加载它。然后尝试将其作为 docker 容器运行并暴露端口 8080。列出了容器，端口列显示如下：0.0.0.0:8080->8080/tcp。

所以我认为该服务正在运行，但我无法使用 ip-addres/eureka 访问它。

如何打开 Eureka 仪表板？

编辑： 我更改了端口，现在容器的端口列显示：0.0.0.0:8761->8761/tcp

这是日志：

Answer 1

对于您的问题，您无法访问该容器。据我所知，可能的原因如下：

1. 容器运行不正常。
2. 容器运行良好，但应用程序在容器内运行不佳。
3. 容器和应用程序都运行良好，但您暴露了错误的端口。该端口不是应用程序在容器内侦听的端口。

所以你需要检查上面的点。我发现默认端口是8761，你需要设置配置。看看Containerize-Spring-Cloud-Eureka-Server。
