Vagrant

vagrant box add <box_image_name> <imageURL>
vagrant init <box_image_name>
# Vagrantfile: memory 4096 등
vagrant up && vagrant ssh
sudo passwd vagrant

도구

# Docker
sudo usermod -aG docker $USER   # 재로그인 후
docker version

# Go
echo 'export GOPATH=$HOME/go' >> ~/.profile
echo 'export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin' >> ~/.profile
source ~/.profile

jq --version

Fabric samples

mkdir -p $HOME/go/src/github.com/<user>
cd $HOME/go/src/github.com/<user>
chmod +x install-fabric.sh && ./install-fabric.sh

test-network

cd $HOME/go/src/github.com/<user>/fabric-samples/test-network
./network.sh up
./network.sh createChannel -c mychannel
./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go
./network.sh down

• deployCC: -ccn 이름, -ccp 경로, -ccl 언어(go|java|javascript|typescript)
