docker port개방

NodeJS, npm 설치

nvm사용해서 NodeJS 설치

$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.4/install.sh | bash
$ source ~/.bashrc
$ nvm install v8.9.4

설치완료 확인

$ node -v
$ npm -v

Docker 설치

아래의 명령어를 사용하여 설치에 필요한 패키지 설치

$ sudo apt-get update && sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common

아래의 명령어를 사용하여 패키지 저장소 추가

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

아래의 명렁어 사용하여 docker package 있는지 확인

$ sudo apt-get update && sudo apt-cache search docker-ce

Docker 설치

```
$ ./change_hostname.sh
```

fabric이름의 stack 으로 각 PC 에서 docker-compose-pc파일 deploy

PC1

$ docker stack deploy -c docker-compose-pc1.yaml fabric

PC2

$ docker stack deploy -c docker-compose-pc2.yaml fabric

PC3

$ docker stack deploy -c docker-compose-pc3.yaml fabric

PC4

$ docker stack deploy -c docker-compose-pc4.yaml fabric

PC5

$ docker stack deploy -c docker-compose-pc5.yaml fabric

아래 명령어로 docker stack service 확인
```
docker service ls
```
위와같이 확인되면 성공

PC4 (org1cli)

org1cli를 가지고 있는 PC4에서 수행, org1cli docker container에 접속
```
$ docker exec -it <docker cli name> bash
```
ex) $ docker exec -it fabric_org1cli.1.ft35iw2ltv2gf08j0d4zcsi34 bash

성공시 아래와같은 command line
```
root@91eceaddee91:/opt/gopath/src/github.com/hyperledger/fabric/peer#
```

Join Channel, Update Anchor Peer, Install Chaincode, Instantiate Chaincode는 Peer를 돌아가면서 해야하기때문에 인증서를 계속 바꾸어주어야한다.

Create & Join Channel

change Org1-Peer0
$ peer channel create -o orderer0.example.com:7050 -c mychannel -f ./channel-artifacts/channel.tx
$ peer channel join -b mychannel.block
change Org1-Peer1
$ peer channel join -b mychannel.block
change Org2-Peer0
$ peer channel join -b mychannel.block
change Org2-Peer1
$ peer channel join -b mychannel.block

Update Anchor Peer

change Org1-Peer0
$ peer channel update -o orderer0.example.com:7050 -c mychannel -f ./channel-artifacts/Org1MSPanchors.tx
change Org2-Peer0
$ peer channel update -o orderer0.example.com:7050 -c mychannel -f ./channel-artifacts/Org2MSPanchors.tx

Install Chaincode

change Org1-Peer0
$ peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02
change Org1-Peer1
$ peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02
change Org2-Peer0
$ peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02
change Org2-Peer1
$ peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02

Instantiate Chaincode - instantiate 명령어는 chaincode가 installed된 Peer중 한곳에서만 사용

아래의 명령어 사용후 instantiated된 chaincode image가 만들어지기때문에 소량의 시간 소모
```
$ peer chaincode instantiate -o orderer0.example.com:7050 -C mychannel -n mycc -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "OR ('Org1MSP.member','Org2MSP.member')"
```

Query Chaincode

peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

100 출력하면 성공
