使用Hyperledger Fabric创建频道失败？

Question

我在docker中构建了一个带有Hyperledger结构的自定义网络。但是当我尝试构建一个通道时它会因此错误而失败。

 Error: got unexpected status: BAD_REQUEST -- error authorizing update: error validating DeltaSet: policy for [Group]  /Channel/Application not satisfied: Failed to reach implicit threshold of 1 sub-policies, required 1 remaining

当我查找orderer的日志时它会在终端上留下这个。

这就是我的订购者设置的样子。

我尝试了这个问题中提出的一切。

peer channel creation fails in Hyperledger Fabric

但我无法找到我做错的地方。有人可以帮我解决这个问题吗？谢谢。

该错误表示您尝试创建的频道已经创建，并且您正尝试使用channel.tx文件再次创建它。可能你没有清理你的docker容器，也没有完全重启容器。

要验证尝试更改通道名称，请重新创建anchor.tx和channel.tx文件等工件，然后使用新名称和文件重新提交。

要清理docker容器并完全重启，请执行以下操作：

注意：根据<consortiumName >文件中指定的值替换configtx.yaml。

• docker rm -f -v `docker ps -a --no-trunc | grep "<consortiumName>-" | cut -d ' ' -f 1` 2>/dev/null || true
• docker rmi `docker images --no-trunc | grep "<consortiumName>-" | cut -d ' ' -f 1` 2>/dev/null || true
