+进入 chaincode 目录中，创建并进入 testcdb 目录：
+```shell
+cd hyfa/fabric-samples/chaincode
+sudo mkdir testcdb
+cd testcdb
+```
+
+将编写的 main.go 文件上传至 testcdb 目录中，然后跳转至fabric-samples的chaincode-docker-devmode目录
+
+```shell
+cd ~/hyfa/fabric-samples/chaincode-docker-devmode/
+```
+
+#### 1. 终端1 启动网络
+```shell
+sudo docker-compose -f docker-compose-simple.yaml up -d
+```
+> 在执行启动网络的命令之前确保无Fabric网络处于运行状态，如果有网络在运行，请先关闭。
+
+#### 2. 终端2 建立并启动链码
+
+**2.1 打开一个新终端2，进入 chaincode 容器**
+```shell
+sudo docker exec -it chaincode bash
+```
+**2.2 编译**  
+进入 testcdb 目录编译 chaincode
+```shell
+cd testcdb
+go build
+```
+**2.3 运行chaincode**
+```shell
+CORE_PEER_ADDRESS=peer:7052 CORE_CHAINCODE_ID_NAME=cdb:0 ./testcdb
+```
+命令执行后输出如下：
+```shell
+[shim] SetupChaincodeLogging -> INFO 001 Chaincode log level not provided; defaulting to: INFO
+[shim] SetupChaincodeLogging -> INFO 002 Chaincode (build level: ) starting up ...
+```
+#### 3. 终端3 测试
+
+**3.1 打开一个新的终端3，进入 cli 容器**
+```shell
+sudo docker exec -it cli bash
+```
+**3.2 安装链码**
+```shell
+peer chaincode install -p chaincodedev/chaincode/testcdb -n cdb -v 0
+```
+**3.3 实例化链码**
+```shell
+peer chaincode instantiate -n cdb -v 0 -C myc -c '{"Args":["init"]}'
+```
+**3.4 初始化数据**
+
+指定调用 billInit 函数进行数据的初始化：
+```shell
+peer chaincode invoke -n cdb -C myc -c '{"Args":["carInit"]}'
+```
+执行成功，输出如下内容：
+```shell
+......
+[chaincodeCmd] chaincodeInvokeOrQuery -> INFO 0a8 Chaincode invoke successful. result: status:200 payload:"\345\210\235\345\247\213\345\214\226\347\245\250\346\215\256\346\210\220\345\212\237"
+```
+
+**3.5 根据 owner 查询数据**
+
+指定调用 queryCars 函数，查询指定用户 p1
+```shell
+peer chaincode query -n cdb -C myc -c '{"Args":["queryCars", "{\"selector\":{\"owner\":\"p1\"}}"]}'
+```
+
+执行成功，输出查询到的结果如下：
+```shell
+......
+key:car001, Value: {"brand":"brand-1","carid":"car001","carname":"car-wife","docType":"carObj","owner":"p1","price":"20"}; key:car002, Value: {"brand":"brand-2","carid":"car002","carname":"car-me","docType":"carObj","owner":"p1","price":"40"}; key:car003, Value: {"brand":"audi-3","carid":"car003","carname":"car-son","docType":"carObj","owner":"p1","price":"20"}
+```
+
+**3.6 根据 owner 以及指定 brand 来查询**
+
+```shell
+peer chaincode query -n cdb -C myc -c '{"Args":["queryCars", "{\"selector\":{\"owner\":\"p1\", \"brand\":\"brand-2\"}}"]}'
+```
+结果：
+```shell
+key:car001, Value: {"brand":"brand-1","carid":"car001","carname":"car-wife","docType":"carObj","owner":"p1","price":"20"}; key:car002, Value: {"brand":"brand-2","carid":"car002","carname":"car-me","docType":"carObj","owner":"p1","price":"40"}
+```
+
+**3.7 根据 owner 以及 brand 的正则表达式匹配规则来查询**
+
+指定调用 queryCars 函数：
+```shell
+peer chaincode query -n cdb -C myc -c '{"Args":["queryCars", "{\"selector\":{\"owner\":\"p1\", \"brand\":{\"$regex\":\"^brand\"}}}"]}'
+```
+执行成功，输出查询到的结果如下：
+```shell
+......
+key:car001, Value: {"brand":"brand-1","carid":"car001","carname":"car-wife","docType":"carObj","owner":"p1","price":"20"}; key:car002, Value: {"brand":"brand-2","carid":"car002","carname":"car-me","docType":"carObj","owner":"p1","price":"40"}
+
+```
