如何在 docker-compose 中从一个容器连接到另一个容器？

Question

我正在尝试运行 8 个容器。 4个节点和4个abci节点。这是我的 docker-compose 文件

想法是将每个节点连接到它的 abci 节点。所有节点之间共享的配置文件位于目录中名为 build 的文件夹中。

version: '3'

services:
  node0:
    container_name: node0
    image: "tendermintnode"
    ports:
      - "26656-26657:26656-26657"
    environment:
      - ID=0
      - LOG=$${LOG:-tendermint.log}
    build:
      context: .
      dockerfile: abci.Dockerfile
    volumes:
      - ./build:/tendermint
    command: tendermint node --proxy_app=tcp://abci0:26658 --home "./tendermint/node0" --consensus.create_empty_blocks=false
    depends_on:
      - abci0
    networks:
      localnet:
        ipv4_address: 192.167.10.2

  node1:
   .

  node2:

  node3:
   .

  abci0:
    container_name: abci0
    image: "abcinode"
    build:
      context: .
      dockerfile: abci.Dockerfile
    command: python3 vimana/tendermint/app.py
    networks:
      localnet:
        ipv4_address: 192.167.10.6

  abci1:
   .
  abci2:
    .
  abci3:
    .
networks:
 .

本来应该开始互相发送请求的。但它却给出了。

如您所见，abci 容器运行良好。但是连接被拒绝了。

基本上，除了像下面这样将相关的容器定义留在同一网络区域之外，您什么都不用做，并且您不必提供特定的 IP 地址（如果您真的不需要。）。

version: "3"
services:
    node0:
        image: ...
        networks:
            - abci0_net
    node1:
        image: ...
        networks:
            - abci1_net

    node2:
        image: ...
        networks:
            - abci2_net

    abci0:
        image: ...
        networks:
            - abci0_net
    abci1:
        image: ...
        networks:
            - abci1_net

    abci2:
        image: ...
        networks:
            - abci2_net         

networks:
    abci0_net:
        driver: bridge
    abci1_net:
        driver: bridge
    abci2_net:
        driver: bridge

通过配置，只有配对的机器可以互相访问。

求解答的人，PRhttps://github.com/tendermint/tendermint/pull/3195/files前几天被合并开发
