多个CMD运行在对接组合中，但没有在容器上生效。

Question

我有一个构建GoBGP扬声器映像的dockefile。

这是dockerfile

FROM ubuntu:16.04

RUN apt-get update && apt-get install -y \
        wget \
        iputils-ping \
        traceroute \
        tcpdump \
        iproute2 \
        && rm -rf /var/lib/apt/lists/*

RUN wget https://github.com/osrg/gobgp/releases/download/v1.25/gobgp_1.25_linux_amd64.tar.gz && \
    tar zxvf gobgp_1.25_linux_amd64.tar.gz && \
    mv gobgp* /usr/bin/

RUN mkdir -p /opt/gobgp
WORKDIR /opt/gobgp/

COPY docker/gobgp/configs/* ./configs/

CMD ["gobgpd"]
EXPOSE 50051

我也有一个对接-撰写，将带来一个完整的gobgp网络拓扑。我试图在gobgp_1服务上执行多个命令：

gobgp_1:
    build:
      context: ./
      dockerfile: ./docker/gobgp/Dockerfile
    command: sh -c "gobgpd -f configs/gobgpd_1.conf ; gobgp global rib add -a ipv4 11.8.0.0/24
               ; gobgp global rib add -a ipv4 11.7.0.0/24
               ; gobgp global rib add -a ipv4 11.6.0.0/24
               ; gobgp global rib add -a ipv4 11.5.0.0/24
               "
    privileged: true
    networks:
      net5:
        ipv4_address: 11.8.0.2
      net6:
        ipv4_address: 11.7.0.2
      net7:
        ipv4_address: 11.6.0.3
      net8:
        ipv4_address: 11.5.0.3

gobgpd -f configs/gobgpd_1.conf命令成功运行，但其余命令运行，但它没有在gobgpd应用程序上生效。如果我通过跳入容器bash手动运行这些命令，则该命令将成功运行，并且我看到gobgpd应用程序上的更改。

当我使用以下命令时，为您提供我所期望的信息的上下文：gobgp global rib，但是我没有看到任何东西，在我把对接器-组合起来之后。否则，如果在运行命令时手动运行，则会看到预期的信息。

这是我所有的码头组成文件。

Answer 1

GoBGP只是一个bgp守护进程，它本身不包含任何修改路由表osrg/gobgp#1493的功能。

如果您希望使用GoBGP作为软件路由器的组件并进行数据包转发，则需要实现以下两个选项来实现FIB操作，即使用GoBGP使用内置斑马集成使用gRPC API编写您自己的代码。

使用斑马的例子

[global.config]
  as = 2
  router-id = "172.17.0.3"

[zebra]
    [zebra.config]
        enabled = true
        url = "unix:/var/run/quagga/zserv.api"
        redistribute-route-type-list = ["connect"]
        version = 2
