Important things to read

Getting Started

curl -sSL https://bit.ly/2ysbOFE | bash -s -- 2.2.1 1.4.7

You want to copy over all the bin files into a bin directory where you can easily access them. I usually just like to make a bin folder in my home directory and set the path to include that

mkdir -p ~/bin
cp fabric-samples/bin/* ~/bin

You then need to add to your bash the path and then source it. I use ZSH so this is how I do it. Copy this into your bash file

export PATH=$PATH:~/bin

Then source your bash so they are available. Check the execs and make sure they work

source ~/.zshrc

This is what you should see

☁  k8s-hyperledger-fabric-2.2 [master] ⚡  configtxgen --version
configtxgen:
 Version: 2.2.1
 Commit SHA: 344fda602
 Go version: go1.14.4
 OS/Arch: linux/amd64
☁  k8s-hyperledger-fabric-2.2 [master] ⚡

You then need to install Go and Nodejs... I would also suggest installing vue cli but I've included all the files you need for the front end.

Some other ways to run the network (good place to look for automation scripts in cli-peer start scripts)

Of if you want to use the auto-join yaml: NOTE - this is experimental and it may not work for you

  • uses some unique scripts to auto join the peers and install chaincodes
docker-compose -f network/docker/docker-compose-auto-join.yaml up

Lets go ahead and test this chaincode

docker exec -it cli-peer0-ibm bash -c 'peer chaincode invoke -C mainchannel -n resource_types -c '\''{"Args":["SetPrivateData", "1", "IBM Private Name"]}'\'' -o orderer0:7050 --tls --cafile=/etc/hyperledger/orderers/msp/tlscacerts/orderers-ca-7054.pem'
docker exec -it cli-peer0-oracle bash -c 'peer chaincode invoke -C mainchannel -n resource_types -c '\''{"Args":["SetPrivateData", "1", "ORACLE Private Name"]}'\'' -o orderer0:7050 --tls --cafile=/etc/hyperledger/orderers/msp/tlscacerts/orderers-ca-7054.pem'

sleep 5

docker exec -it cli-peer0-ibm bash -c 'peer chaincode query -C mainchannel -n resource_types -c '\''{"Args":["Index"]}'\'' -o orderer0:7050 --tls --cafile=/etc/hyperledger/orderers/msp/tlscacerts/orderers-ca-7054.pem'
docker exec -it cli-peer0-oracle bash -c 'peer chaincode query -C mainchannel -n resource_types -c '\''{"Args":["Index"]}'\'' -o orderer0:7050 --tls --cafile=/etc/hyperledger/orderers/msp/tlscacerts/orderers-ca-7054.pem'

docker exec -it cli-peer0-oracle bash -c 'peer chaincode query -C mainchannel -n resource_types -c '\''{"Args":["Transactions","1"]}'\'' -o orderer0:7050 --tls --cafile=/etc/hyperledger/orderers/msp/tlscacerts/orderers-ca-7054.pem'
docker exec -it cli-peer0-ibm bash -c 'peer chaincode query -C mainchannel -n resource_types -c '\''{"Args":["Transactions","1"]}'\'' -o orderer0:7050 --tls --cafile=/etc/hyperledger/orderers/msp/tlscacerts/orderers-ca-7054.pem'

Commands

Clean all docker things

docker system prune
docker container prune
docker volume prune
docker rmi $(docker images -q) --force

Kill minikube env

minikube delete

You can purge everything with

minikube delete --purge

You can find and replace file names like this

sudo find . -depth -name '*org1*' -execdir bash -c 'mv -i "$1" "${1//org1/ibm}"' bash {} \;
sudo find . -depth -name '*org2*' -execdir bash -c 'mv -i "$1" "${1//org2/oracle}"' bash {} \;

Common issues

Error: ENOSPC: System limit for number of file watchers reached, watch '/home/nick/Projects/k8s-hyperledger-fabric-2.2/frontend/public/index.html'

Run this command

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
