Run BDLS-Fabric

Google-cloud Ubuntu VM

Step 1

sudo apt update && sudo apt upgrade -y
sudo snap install go --classic
sudo apt install jq -y
sudo apt install curl -y
sudo snap install yq
sudo apt install build-essential
sudo apt install git

Step 2

mkdir -p $HOME/go/src/github.com/BDLS-bft/

cd $HOME/go/src/github.com/BDLS-bft/

curl -sSLO https://raw.githubusercontent.com/hyperledger/fabric/main/scripts/install-fabric.sh && chmod +x install-fabric.sh

./install-fabric.sh samples binary

Step 3

cd fabric-samples/

yq -i 'del(.chaincode.externalBuilders) | .chaincode.externalBuilders[0].name = "ccaas_builder" | .chaincode.externalBuilders[0].path = env(PWD) + "/builders/ccaas" | .chaincode.externalBuilders[0].propagateEnvironment[0] = "CHAINCODE_AS_A_SERVICE_BUILDER_CONFIG"' config/core.yaml

cd test-network-nano-bash

./configureExternalBuilders.sh

Step 4

cd ../..
git clone https://github.com/hyperledger-labs/bdls fabric

cd fabric 
make configtxlator configtxgen cryptogen orderer osnadmin peer discover ledgerutil

Step 5

edit Orderer 
 cd fabric-samples/config/
 vi orderer.yaml 
 delete Kafka section

vi ~/.bashrc
export FABRIC_CFG_PATH=${PWD}/../config
source ~/.bashrc

Step 6

(Running the experimental)

  • We need at least 5 terminals to run the experimental. Running the comment from the diffrent terminals or tmux new session and splite the screen. Tew options a or b.
cd ../test-network-nano-bash/

a.

  • In the first orderer terminal, run ./generate_artifacts.sh BFT to generate crypto material (calls cryptogen) and application channel genesis block and configuration transactions (calls configtxgen). The artifacts will be created in the crypto-config and channel-artifacts directories.
  • In the four orderer terminals, run ./orderer1.sh, ./orderer2.sh, ./orderer3.sh, ./orderer4.sh respectively.
  • Note that each orderer and peer write their data (including their ledgers) to their own subdirectory under the data directory
  • Open a different terminal and run ./join_orderers.sh BFT.

b. tmux use to create new session then split till you get five sessions.

tmux new -s mysession
tmux split-window -v
tmux select-pane -t 0

The uses like:

./generate_artifacts.sh BFT
./orderer1.sh & tmux select-pane -t 1
./orderer2.sh & tmux select-pane -t 2
./orderer3.sh & tmux select-pane -t 3
./orderer4.sh & tmux select-pane -t 4
./join_orderers.sh BFT

Troubleshooting

  1. yq is updating the yaml file, maybe version not compatible try to reinstall it by:
sudo wget https://github.com/mikefarah/yq/releases/latest/download/yq_linux_amd64 -O /usr/bin/yq &&    chmod +x /
usr/bin/yq

Then run the yq commend in Step 3 If it didn't work, you can edit the file manually, using vim or nano fabric-samples/config/core.yaml by navigate this section in file:

externalBuilders:
  - name: ccaas_builder
    path: /Users/nanofab/fabric-samples/builders/ccaas
    propagateEnvironment:
      - CHAINCODE_AS_A_SERVICE_BUILDER_CONFIG

update the path: env(PWD) + "/builders/ccaas"

  • For example, mine is: path: /home/ahmed/go/src/github.com/BDLS-bft/fabric-samples/builders/ccaas
git --version

No results

sudo apt install git
