集群启动后，进入一个 VP 节点。以 pbft 模式为例，节点名称为 。

    部署 chaincode example02。

    1. $ peer chaincode deploy -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -c '{"Function":"init", "Args": ["a","100", "b", "200"]}'
    2. Deploy chaincode: ee5b24a1f17c356dd5f6e37307922e39ddba12e5d2e203ed93401d7d05eb0dd194fb9070549c5dc31eb63f4e654dbd5a1d86cbb30c48e3ab1812590cd0f78539

    部署成功后，系统中会自动生成几个 chaincode 容器，例如

    1. CONTAINER ID        IMAGE                                                                                                                                      COMMAND                  CREATED             STATUS              PORTS                                   NAMES

    查询 a 手头的价值，为初始值 100。

    1. $ peer chaincode invoke -n ${CC_ID} -c '{"Function": "invoke", "Args": ["a", "b", "10"]}'

    查询 a 手头的价值，为新的值 90。
