Hyperledger/fabric(v0.7) create and join peer to a new channel

用docker搭建fabric网络

找到sfhackfest目录

cd $GOPATH/src/github.com/hyperledger/fabric/examples/sfhackfest

确保docker-compose文件用到的imags都有

docker-compose -f docker-compose-gettingstarted.yml build

构建网络并把peer添加到channel

docker-compose -f docker-compose-gettingstarted.yml up -d

创建自己的channel

进入cli容器

docker exec -it cli bash

创建channel

CORE_PEER_COMMITTER_LEDGER_ORDERER=orderer:7050 peer channel create -c myc2

这里channel的名称是

myc2

会发现当前路径下多了一个文件

myc2.block

这个是channel的创始区块(fabric的官方文档说明的)

把peer0节点添加到myc2的channel

CORE_PEER_COMMITTER_LEDGER_ORDERER=orderer:7050 CORE_PEER_ADDRESS=peer0:7051 peer channel join -b myc2.block

这时在peer0的

/var/hyperledger/production/ledgersData/blocks/blocks

会多出来channel名字的文件夹

myc2

里面包含一个区块文件

blockfile_000000

发布合约

CORE_PEER_ADDRESS=peer0:7051 CORE_PEER_COMMITTER_LEDGER_ORDERER=orderer:7050 peer chaincode deploy -C myc2 -n mycc -p github.com/hyperledger/fabric/examples -c '{"Args":["init","a","100","b","200"]}'

合约调用

CORE_PEER_ADDRESS=peer0:7051 CORE_PEER_COMMITTER_LEDGER_ORDERER=orderer:7050 peer chaincode invoke -C myc2 -n mycc -c '{"function":"invoke","Args":["move","a","b","10"]}'

查询状态

CORE_PEER_ADDRESS=peer0:7051 CORE_PEER_COMMITTER_LEDGER_ORDERER=orderer:7050 peer chaincode query -C myc2 -n mycc -c '{"function":"invoke","Args":["query","a"]}'
