Question

嗨，我只是想知道在docker文件中定义对等时，我们正在设置环境变量“ -CORE_PEER_ADDRESS = peer0.org1.example.com：7051 ” 那么为什么还要为其他组织使用相同的“ 7051 ”端口。正如我在下面的文件中看到的那样，他们在org2中定义对等方时，他们使用了相同的端口。我只是想知道这一点。

Answer 1

在docker-composer文件中，右侧端口7051属于运行容器的HostOS。

基于此配置，7051端口被映射到左侧的Peer端口，以便与HOST OS进行通信。

例如，您可以从主机OS运行CLI实用程序。

Answer 2

核心对等地址仅对于客户端节点是必需的。在其他节点上并不是必须的。在客户端节点上，该节点将指示要在哪个对等方上执行所使用的命令，例如安装链码或调用它。

例如，假设您有2个对等方，并且要在其上安装2个链式代码，那么在首次执行并执行时，它将在您定义为CORE_PEER_ADDRESS的计算机上执行代码：

peer chaincode install -p <path> -n <name> -v <version>

现在，要安装其他链式代码，您需要将CORE_PEER_ADDRESS设置为下一个对等体：

export CORE_PEER_ADDRESS=peer1.kaytek.es:7051
peer chaincode install -p <path> -n <name> -v <version>

超账结构中的CORE_PEER_ADDRESS是什么？
