Question

有两个具有以下配置的Docker容器：

version: '2'

services:

  host:
    ports:
      - 8081:8081
    build:
      context: .
      dockerfile: Dockerfile
      args:
        PROJECT_DIR: Host
        PROJECT_NAME: Host
        WAIT_FOR_HOST: 0
    restart: on-failure

  client:
    depends_on:
      - host
    ports:
      - 8082:8082
    build:
      context: .
      dockerfile: Dockerfile
      args:
        PROJECT_DIR: Client
        PROJECT_NAME: Client
        WAIT_FOR_HOST: 1
    restart: on-failure

  tcpdump:
    image: kaazing/tcpdump
    network_mode: "host"
    volumes:
      - ./tcpdump:/tcpdump

同时启动的应用程序都通过TCP / IP进行通信。

这是网络配置：

当我在Wireshark中分析网络通信时，我可以看到多个乱序的TCP数据包。

您有什么建议为什么会发生以及如何解决？这可能是解决我在here中描述的其他问题的可能解决方案。

Answer 1

您可以查看数据包的MAC地址吗？如果仔细观察，数据包77和数据包78具有相似的有效负载。有一种可能，容器正在使用网桥的MAC地址发送数据包，而网桥正在路由数据包。

容器内部的

ip route可以通过路由或桥接确认数据包之间的通信是否发生。
