我一直在尝试使用Hyperledger Fabric，使用docker swarm部署2个VirtualBox Ubuntu映像。但是在Composer安装方面我遇到了一些问题。
网络设置：
Host1：Orderer，Peer1.Org1，Peer2.Org1，CLI
Host2：Peer1.Org2，Peer2.Org2
在Fabric设置方面，一切似乎都没问题。我能够启动网络，加入来自第二个主机的对等端，并更新锚点对等体（每个组织一个）。
Composer安装从创建和导入业务网卡开始，然后将.bna文件安装到网络上。
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

当我从org1检查第一个对等体时，我看到以下错误：

有人知道我接下来会尝试什么吗？
composer network start命令正在尝试为每个对等体启动一个“chaincode”容器，并且从您显示的错误中，有两个对等体无法启动这些新容器。
该错误看起来像Docker错误 - 无法在名为“net_example”的网桥上启动容器。我猜你在你的一个定义这个变量的docker-compose-xxx.yaml文件中定义了一个环境变量：CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE，它确定新容器连接到哪个网桥。
您需要确定我们的其他Fabric容器正在使用哪个网桥，然后将.yaml中的此变量设置为该网桥。
这个previous post对多主机结构进行了一些讨论。
我不认为你需要Docker Swarm来进行多主机Fabric设置。我尝试使用Altoros的这个工具来轻松设置多主机Fabric。它确实与Fabric 1.1一起使用。对于1.2它没有用 - 我认为它需要一些改变。

Debut Infotech还有另一款工具。你也可以尝试一下。 https://www.fabricdeployer.com/
早期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
