詳細的環境安裝可以微信掃一掃![]()
1.先進入sample的目錄啓動服務
cd chaincode-docker-devmode
啓動相應的docker實例中使用了已經寫了相應的編排文件如下所示
.
├── chaincode
├── docker-compose-simple.yaml
├── msp
│ ├── admincerts
│ │ └── admincert.pem
│ ├── cacerts
│ │ └── cacert.pem
│ ├── keystore
│ │ └── key.pem
│ ├── signcerts
│ │ └── peer.pem
│ ├── tlscacerts
│ │ └── tlsroot.pem
│ └── tlsintermediatecerts
│ └── tlsintermediate.pem
├── myc.block
├── myc.tx
├── orderer.block
├── README.rst
└── script.sh
執行命令這個命令是docker-compose編排啓動文件如果想後臺運行的話可以加個-d參數
docker-compose -f docker-compose-simple.yaml up
注意如果這裏出現了證書錯誤的情況就切換到master主分支
2.開始編譯區塊鏈
在第一步中啓動程序會爲我們啓動一個開發環境的容器名爲chinacode，我們編譯直接進入該容器進行操作
docker exec -it chaincode bash
我看到默認的主目錄爲chaincode
root@d2629980e76b:/opt/gopath/src/chaincode#
現在編譯sacc
cd sacc
go build
編譯完直接運行
CORE_PEER_ADDRESS=peer:7052 CORE_CHAINCODE_ID_NAME=mycc:0 ./sacc
顯示如下
/saccchaincode/sacc#CORE_PEER_ADDRESS=peer:7052 CORE_CHAINCODE_ID_NAME=mycc:0 ./sacc
2018-05-04 08:56:18.486 UTC [shim] SetupChaincodeLogging -> INFO 001 Chaincode log level not provided; defaulting to: INFO
2018-05-04 08:56:18.486 UTC [shim] SetupChaincodeLogging -> INFO 002 Chaincode (build level: ) starting up ...
peer容器logs顯示已註冊channelID不存在
peer | 2018-05-04 09:40:33.425 UTC [chaincode] beforeRegisterEvent -> DEBU 338 Received REGISTER in state created
peer | 2018-05-04 09:40:33.425 UTC [chaincode] registerHandler -> DEBU 339 registered handler complete for chaincode mycc:0
peer | 2018-05-04 09:40:33.425 UTC [chaincode] beforeRegisterEvent -> DEBU 33a Got REGISTER for chaincodeID = name:"mycc:0" , sending back REGISTERED
peer | 2018-05-04 09:40:33.425 UTC [chaincode] notifyDuringStartup -> DEBU 33b nothing to notify (dev mode ?)
peer | 2018-05-04 09:40:33.425 UTC [chaincode] notifyDuringStartup -> DEBU 33c sending READY
peer | 2018-05-04 09:40:33.425 UTC [chaincode] processStream -> DEBU 33d []Move state message READY
peer | 2018-05-04 09:40:33.426 UTC [chaincode] handleMessage -> DEBU 33e []Fabric side Handling ChaincodeMessage of type: READY in state established
peer | 2018-05-04 09:40:33.426 UTC [chaincode] enterReadyState -> DEBU 33f []Entered state ready
peer | 2018-05-04 09:40:33.426 UTC [chaincode] notify -> DEBU 340 notifier Txid:, channelID: does not exist
此時雖然程序已經註冊但是未和其他的管道間關聯
3.安裝實例化
由於上步的執行進行了堵塞的shell，所以這步需要重新開啓一個shell進行安裝實例化
進入cli開發環境
docker exec -it cli bash
安裝
peer chaincode install -p chaincodedev/chaincode/sacc -n mycc -v 0
peer chaincode instantiate -n mycc -v 0 -c '{"Args":["a","10"]}' -C myc
好了這步基本上a向區塊鏈寫入了10
如果上步錯了想修改20執行如下
peer chaincode invoke -n mycc -c '{"Args":["set", "a", "20"]}' -C myc
想查看下使用如下命令
peer chaincode query -n mycc -c '{"Args":["query","a"]}' -C myc
