我目前正在研究使用多个 docker 容器的超级账本区块链：

  • dev-peer0.org1.example.com-marbles-v5.9
  • peer0.org1.example.com
  • 沙发数据库
  • orderer.example.com
  • cli
  • ca.example.com

在默认配置下，它们都在同一台机器上运行。

我想要实现的是将它们划分在两台不同的计算机上：

电脑1：

  • dev-peer0.org1.example.com-marbles-v5.9
  • peer0.org1.example.com
  • 沙发数据库

电脑2：

  • orderer.example.com
  • cli
  • ca.example.com

我可以在不编辑任何 conf 文件的情况下使用主机文件来完成这项工作吗？

PC1：

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.31.128.146 orderer.example.com
10.31.128.146 cli
10.31.128.146 ca.example.com

PC2：

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.31.128.198 dev-peer0.org1.example.com-marbles-v5.9
10.31.128.198 peer0.org1.example.com
10.31.128.198 couchdb

我已经尝试过但我没有工作，但我想知道我是否应该更多地采用这种方式？

我建议为覆盖网络启用 Swarm 模式。理想情况下，您甚至可以在 Swarm 模式下运行容器，但这对于覆盖网络来说并不是必需的。

一台一台主机，运行以下命令创建管理器：

docker swarm init

docker swarm join然后在第二台主机上运行输出命令。

选项 A：仅对于覆盖网络，您需要创建一个可附加的网络，以便在群模式之外使用它：

docker network create -d overlay --attachable basic

然后在您的撰写文件中，将网络定义调整为外部：

version: '2'
networks:
  basic:
    external:
      name: basic

这样，您的容器将能够直接通过覆盖网络进行通信。

选项 B：要使用 Swarm 模式运行容器，您可以跳过网络创建并将网络设置为外部。只需将您的版本更新到version: '3'您的 compose.yml 文件中，我也会删除“container_name”行。然后运行：

docker stack deploy -c compose.yml hyperledger

创建一个称为超级账本的堆栈。

如果您想沿着 hosts 路线走，您需要使用/添加extra_hosts到您的每个撰写服务定义中。
