docker - Hyperledger Composer - 多主机安装
问题描述
我一直在试验 Hyperledger Fabric，使用 docker swarm 部署了超过 2 个 VirtualBox Ubuntu 映像。但是在安装 Composer 时我遇到了一些问题。
网络设置：
Host1：Orderer、Peer1.Org1、Peer2.Org1、CLI
主机 2：Peer1.Org2、Peer2.Org2
当涉及到 Fabric 设置时，一切似乎都很好。我能够启动网络，从第二台主机加入对等点，并更新锚点对等点（每个组织一个）。
Composer 安装首先创建和导入业务网卡，然后将 .bna 文件安装到网络上。
当我尝试启动网络时出现问题：
Error: Error trying to start business network. Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: failed to execute transaction 14f90ad938da64fbbdb2923b07f4985251391937fc3fdc8bab19c2d13135ecd3: error starting container: error starting container: API error (500): Could not attach to network net_example: rpc error: code = NotFound desc = network net_example not found

Response from attempted peer comms was an error: Error: Failed to connect before the deadline
Response from attempted peer comms was an error: Error: Failed to connect before the deadline
当我检查来自 org1 的第一个对等方时，我看到以下错误：

有人知道我接下来可以尝试什么吗？
解决方案
我认为您不需要 Docker Swarm 来进行多主机 Fabric 设置。我尝试了 Altoros 的这个工具，以便轻松设置多主机 Fabric。它确实适用于 Fabric 1.1。对于 1.2 它不起作用 - 我认为它需要一些更改。

Debut Infotech 还有另一个工具。你也可以试试这个。 https://www.fabricdeployer.com/
早些时候，我尝试使用下面的链接设置 Docker Swarm。有效。 https://medium.com/@wahabjawed/hyperledger-fabric-on-multiple-hosts-a33b08ef24f
