获取背书人客户端通道时出错:背书人客户端无法连接到peer0.org1.example.com:7051



我是Hyperleger Fabric的新手。我正在阅读关于构建你的第一个网络的教程，并陷入了结构示例/第一个网络示例。我第一次跑步：

./byfn.sh generate

然后我运行：

./byfn.sh up

这样做的结果是：

Starting for channel 'mychannel' with CLI timeout of '10' seconds and CLI delay of '3' seconds

我不知道出了什么问题。我该如何解决这个问题？

唯一对我有效的解决方案是增加睡眠时间来启动结构。

  1. 在启动结构之前删除所有超级账本docker图像(startFabric.sh将再次下载最新图像。

    要删除所有容器，包括其使用的卷，

    docker rm -vf $(docker ps -a -q)

    要删除所有图像，

    docker rmi -f $(docker images -a -q)
  2. 打开基本网络/start.sh
  3. 使FABRIC_START_TIMEOUT=90(默认值为10(
  4. /startFabric.sh

我已经遇到过两次这个问题

第1.1.0节

我通过删除所有docker图像来修复它，以便再次下载所有相关图像。因为，在那个时候，我有很多版本的织物图像。

在版本1.2.0中

我在一台新的ecs机器上又遇到了这个问题。

我也通过IBM区块链平台VS代码扩展得到了这个错误。我使用Fabric的1.4.4版本。

我怀疑我的磁盘空间用完了，所以我跑了docker system prune --volumes删除挂起的卷，并获得了22GB的备份(我有其他占用大量空间的docker卷(。请记住，您应该运行要在卷中保留重要数据的容器。这样"修剪"就不会删除这些卷。

之后，我通过VS代码扩展重新启动了IBM区块链平台环境，它正常启动。

我用以下命令清理码头站解决了这个问题：

docker rm -f $(docker ps -aq) && docker rmi -f $(docker images | grep dev | awk '{print $3}') && docker volume prune
