Hyperledger Fabric 创建自己的网络

Question

我能够与一个组织和两个对等方一起创建我的加密配置和通道工件。如何创建类似chaincode-docker-devmode (https://github.com/hyperledger/fabric-samples) 的环境，我可以在其中本地运行我的链代码。我的 docker-compose.yaml 文件应该包含什么。

Answer 1

您的链代码需要在 docker 容器中运行。这取决于您如何编写链代码逻辑 - 如果您使用 Hyperledger Composer（推荐），您需要额外的 docker 包含正在运行的 couch-db，这些存储分类帐数据，每个对等方 1 个 couch-db。如果您是手动编写链代码，则不需要这些额外的容器。

您需要制作一个包含网络拓扑的 yaml 文件。我已将 yaml 文件包含在 hyperledger 提供的 first-network 示例中。 (https://github.com/hyperledger/fabric-samples/tree/release-1.4/first-network) 是指向 github 的链接-我建议您检查一下
