By default, all the peer will join the system chain of `testchainid`.
After the cluster is synced successfully, you can validate by deploying, invoking or querying chaincode from the container or from the host.
```bash
$ docker exec -it fabric-cli bash
root@cli:/go/src/github.com/hyperledger/fabric# peer channel list
Channels peers has joined to:
testchainid
UTC [main] main -> INFO 001 Exiting.....
```
#### Deploy
Use `docker exec -it fabric-peer0 bash` to open a bash inside container `fabric-peer0`, which will accept our chaincode testing commands of `install/instantiate`, `invoke` and `query`.
After the cluster is synced successfully, you can validate by install/instantiate, invoking or querying chaincode from the container or from the host.
Inside the container, run the following command to deploy a new chaincode of the example02. The chaincode will initialize two accounts: `a` and `b`, with value of `100` and `200`.
#### install&instantiate
Use `docker exec -it fabric-cli bash` to open a bash inside container `fabric-cli`, which will accept our chaincode testing commands of `install/instantiate`, `invoke` and `query`.
Inside the container, run the following command to install a new chaincode of the example02. The chaincode will initialize two accounts: `a` and `b`, with value of `100` and `200`.

```
This will take a while, and the result may look like following.
```bash
[golang-platform] writeGopathSrc -> INFO 001 rootDirectory = /go/src
container] WriteFolderToTarPackage -> INFO 002 rootDirectory = /go/src
[main] main -> INFO 003 Exiting.....
```
Then instantiate the chaincode test_cc on defaule channel testchainid.
```bash
root@cli:/go/src/github.com/hyperledger/fabric# peer chaincode instantiate -v 1.0 -n test_cc -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -c '{"Args":["init","a","100","b","200"]}' -o orderer0:7050
```
This will take a while, and the result may look like following:

UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc
UTC [main] main -> INFO 003 Exiting.....
```
There should be no error in the return log, and in the peer nodes's output.
Wait several seconds till the deploy is finished.
If the `peer chaincode install` and `peer chaincode instantiate` commands are executed successfully, there will generate a new chaincode container, besides the 3 existing one, name like `dev-peer0-test_cc-1.0`.
