Spring 启动 Eureka 服务器客户端在 docker 下抛出连接超时
Spring boot Eureka Server Client throws connection timeouts under docker
过去 1.5 年以来，我一直在 Windows Server 2016 上使用 docker Desktop CE。
我在 运行 Spring 里面启动微服务 docker。
从最近几天开始，我突然收到网络连接超时错误。
解决上述问题的唯一方法是重新启动 Docker 桌面。
我尝试更新 docker 桌面，但它说您的 windows 版本不受支持。
Docker Desktop requires Windows 10 Pro/Enterprise (15063+) or Windows 10 Home (19018+).
Windows Server 2016 也是最新的。那么谁能知道 Docker Desktop CE 是否现在不受 Windows Server 2016 上的 Docker 支持？
一些事实
- 我是运行Linux容器
- 我正在使用 7 个微服务
- Docker 版本：- Docker 版本 18.09.2，内部版本 6247962

为什么在配置中使用静态 IPS？容器和 docker 网桥 IP 将在重启时发生变化。尝试使用 docker network 和容器名称进行连接。
过去 1.5 年以来，我一直在 Windows Server 2016 上使用 docker Desktop CE。 我在 运行 Spring 里面启动微服务 docker。 从最近几天开始，我突然收到网络连接超时错误。
解决上述问题的唯一方法是重新启动 Docker 桌面。 我尝试更新 docker 桌面，但它说您的 windows 版本不受支持。
Docker Desktop requires Windows 10 Pro/Enterprise (15063+) or Windows 10 Home (19018+).
Windows Server 2016 也是最新的。那么谁能知道 Docker Desktop CE 是否现在不受 Windows Server 2016 上的 Docker 支持？
