ibm-cloud - Fabric composer 与 Bluemix 区 block 链服务的集成

Question

现在可以将 composer fabric 业务网络 .bna 文件部署到 bluemix 区 block 链服务吗？如果是这样，是否有人可以共享连接配置文件示例？谢谢。

Answer 1

您现在可以将 Composer 与 Bluemix Blockchain 服务结合使用。

但是，您必须运行 Composer Playground 的本地副本，因为在 Bluemix (fabric-composer.mybluemix.net) 上运行的 Composer 版本目前仅支持 Web 连接配置文件。

您可以按照此处的说明设置 Composer Playground 的本地副本:https://fabric-composer.github.io/start/getting-started-playground.html

这是我用来连接到 Bluemix 区 block 链服务的连接配置文件:

URL 中的主机名和端口号必须来自 Bluemix 仪表板。我发现最容易通过导航到“服务凭证”并查看默认凭证“Credentials-1”来获取此信息。以下是对每个 URL 来源的解释:

membershipServicesURL 始终是“grpcs://”+ 来自“ca”对象的 url(url 也是 discovery_host +“:”+ discovery_port)。

peerURL 始终是“grpcs://”+ discovery_host +“:”+ 来自“peers”数组中列出的对等点之一的 discovery_port。

eventHubURL 始终是“grpcs://”+ event_host +“:”+ 来自“peers”数组中列出的对等点之一的 event_port。

keyValStore 是运行 Composer 的系统文件系统上的一个目录。如果使用 Docker 镜像，则使用“/home/composer/.composer-credentials”路径，否则使用计算机上存在的目录。

certificate 来自“us.blockchain.ibm.com.cert”文件，该文件可以从凭证中的“cert”属性下载，例如“https://blockchain-certs.mybluemix.net/us.blockchain.ibm.com.cert”。如果您手动创建此 JSON，则必须确保它以“\n”换行符结尾。

certificatePath 来自凭证中的“cert_path”属性。

您还可以从凭据页面获取用于 Bluemix 的注册 ID 和注册密码；我建议使用“管理员”。请注意，如果您使用 REST API 与 Bluemix 服务交互，那么您不能将这些相同的凭据用于 Composer。

但是，需要注意的一件事是，Bluemix Blockchain 服务可能不可靠，因为事件中心连接因不活动而超时。发生这种情况时，Composer 将终止，您可能会看到一个错误。我们正在等待 hfc(Hyperledger Fabric 客户端)Node.js 模块的修复，它将正确处理此错误并根据需要重新连接。

希望对你有帮助，
