使用了三臺VPC，都是Ubuntu 16.04 LTS版

如果要執行e2e_cli的例子，則必須準備5個節點，一個orderer四個peer並且分兩個org。因為整個建立過程都在script.sh中寫死，必須這些，如果要修改，自己要修改相應的指令碼檔案，指令碼檔案在docker cli中

如果出現啟動peer時，BAD_REQUEST，可以關閉docker orderer，重新進入則就將建立好的channel刪除了。

修改後的script.sh，這是peer0.org1.example.com中的，遮蔽peer0.org2.example.com的使用

s1跑orderer,s2跑peer0.org1和cli, s3跑peer0.org2

只能有一個cli，否則在其他peer join時會出現mychannel.block找不到的情況，因此就需要在一個cli中將所有peer都join到網路中。

如果在另外一臺peer加入到網路時，報下面的錯誤，需要複製cli所在的crypto-config目錄到peer所在的目錄

"x509: ECDSA verification failure\" while trying to verify candidate authority certificate \"tlsca.example.com\")"

如下錯誤，在呼叫peer0.org2.example.com的chaincode時報錯，超時。docker images檢視chaincode的映象在，但就是執行超時，刪除dev-peer0.org2.example.com-mycc-1.0的image，重新呼叫程式碼，則正常了。

Error: Error endorsing query: rpc error: code = Unknown desc = Error executing chaincode: Timeout expired while starting chaincode mycc:1.0(networkid:dev,peerid:peer0.org2.example.com,tx:ab10012b339c8d5b18a3355c6e465db10de193749c9bb50f239dac6d770a85c0) - <nil>
Usage:
  peer chaincode query [flags]
 

如下錯誤,是cli關閉的不完全，重新執行 docker-compose -f cli.yaml down，再執行就可以了

如下錯誤，在docker-compose 加上 --remove-orphans
