Fabric踩坑问题记录（无法创建交易链）

我在生成的时候都挺顺利的。
docker compose 启动也都正常
peer channel list 响应结果也是预期的（可以连上节点，看到连接的通道是空的）
但是我在创建通道的时候发生了异常
具体指令为
peer channel create -o orderer.t4cloud.com:7050 -c t4channel -f /etc/hyperledger/config/t4cloud.tx
其中的orderer.t4cloud.com,容器启动正常，我之前看过docker启动log，确实是等待服务的日志（视频中说这样就是启动成功了）
通道名称t4channel这个也是正常的，我尝试过使用别的，就会提示通道ID不一致。
最后的交易文件读取正常，如果修改成别的，也会提示文件无法读取
令我困惑的是他的异常提示，是空的，导致百度无法下手，看过好一些，无法解决，只能向老师求助一下。

这是我的docker容器运行状态，看起来版本号都是1.0.0应该也没错

此时被提醒查看order节点日志
--以下是补充的order日志
图片描述
我搜索过这个显眼的红色部分的异常，有一个前辈说是order节点的配置不对，正确的应该是GENESISMETHOD=file，我看了docker-compose中的order配置，我的确实是对的。其他能搜索到的结果都和这个不一样，陷入茫然。
然后我注意到了蓝色部分，也去搜索了一下，同样只有疑问没有解决办法。
再次求助前辈，发现我犯了一个简单的错误
以下是我使用的命令
生成证书
./cryptogen generate --config=./crypto-config.yaml
创建创世区块及交易
./configtxgen -profile OneOrgOrdererGenesis -outputBlock ./config/genesis.block -channelID t4channel
./configtxgen -profile TwoOrgChannel -outputCreateChannelTx ./config/t4cloud.tx -channelID t4channel
创建通道
peer channel create -o orderer.t4cloud.com:7050 -c t4channel -f /etc/hyperledger/config/t4cloud.tx
（注意，一个是生成系统链，一个是生成交易链，ID不可一样！）
后续异常补充
在我使用小写的不同的名字的时候，出现了go语言的异常，看起来好像是没有响应信息。
（这个我搜了下说是GO语言的环境有问题，可是当前是在官方的docker镜像中……）

然后看order节点的日志，好像是没问题，都成功了，排除order的问题
图片描述
在这种情况下，我尝试过无视异常，然后加入链，会提示tx文件不存在。
如果再次生成链，会生成失败，提示version为1，我搜了下，好像是代表链已存在。
【最终问题解决，成功创建通道】
网上说可能是容器环境有问题，一样面向百度，发现有个前辈说在官方提供的client容器的GODNS是不对的。看起来是个GO语言的问题，也不管什么容器，在所有的镜像都加上修正参数。
注意点
1.创世区块和交易链的通道ID不能一样
2.通道名称，不能有大写，（因为我写JAVA习惯了驼峰），但是在此处会有一场，order节点日志：通道ID有非法自读
3.cli客户端的环境变量中缺少 - GODEBUG=netdns=go 导致响应异常。
