如何让Docker中两个不同网络中的容器互通呢？

  • 使用docker network connect

    # docker network --help

    Usage:  docker network COMMAND

    Manage networks

    Commands:
      connect     Connect a container to a network
      create      Create a network
      disconnect  Disconnect a container from a network
      inspect     Display detailed information on one or more networks
      ls          List networks
      prune       Remove all unused networks
      rm          Remove one or more networks

    Run 'docker network COMMAND --help' for more information on a command.
    # docker network connect --help

    Usage:  docker network connect [OPTIONS] NETWORK CONTAINER

    Connect a container to a network

    Options:
          --alias strings           Add network-scoped alias for the container
          --driver-opt strings      driver options for the network
          --ip string               IPv4 address (e.g., 172.30.100.104)
          --ip6 string              IPv6 address (e.g., 2001:db8::33)
          --link list               Add link to another container
          --link-local-ip strings   Add a link-local address for the container

  • 将容器container-x加入到网络network-y中
