Hyperledger Composer - 多主机安装

Question

我一直在试验 Hyperledger Fabric，使用 docker 群部署了 2 个 VirtualBox Ubuntu 映像。但是我在安装 Composer 时遇到了一些问题。

网络设置：

主机 1：订购者、Peer1.Org1、Peer2.Org1、CLI

主机 2：Peer1.Org2，Peer2.Org2

当涉及到 Fabric 设置时，一切似乎都正常。我能够启动网络，从第二个主机加入对等点，并更新锚点对等点（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。

尝试启动网络时出现的问题：

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 的第一个对等点时，我看到以下错误：

}

有人知道我接下来可以尝试什么吗？

Answer 1

composer network start 命令正在尝试为每个对等点启动一个 'chaincode' 容器，根据您显示的错误，有 2 个对等点无法启动这些新容器。

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 docker-compose-xxx.yaml 文件中定义了一个环境变量，它定义了这个变量：CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE 决定了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。

此对多主机结构进行了一些讨论。

Answer 2

我认为您不需要 Docker Swarm 来设置多主机 Fabric。我试用了 Altoros 的这个工具来轻松设置多主机 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。

还有另一个来自 Debut Infotech 的工具。你也可以试试这个。 https://www.fabricdeployer.com/

早些时候，我尝试使用下面的 link 设置 Docker Swarm。有效。 https://medium.com/@wahabjawed/hyperledger-fabric-on-multiple-hosts-a33b08ef24f
