K8s Hyperledger 2.2 Network

Important things to read

• Orderering Service
• Peers

Getting Started

• My bash
• Install Hyperledger Deps
• Install fabric binaries and images

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

• Create aws account
• Create docker hub account
• Install Kubectl
• Install Minikube
• Install Docker-compose

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.

• Golang
• Nodejs

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

• Having docker registry issues?
• There is an issue with CA 1.4.9... use 1.4.7
• Really good Golang tutorial
• Issue with watchers

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
