Hyperledger Fabric network in K8s with External Chaincodes as pods

Refer the tutorial and instructions in this article: https://medium.com/@pau.aragones/how-to-implement-hyperledger-fabric-external-chaincodes-within-a-kubernetes-cluster-fd01d7544523

Install the binaries

wget https://github.com/hyperledger/fabric/releases/download/v2.3.1/hyperledger-fabric-linux-amd64-2.3.1.tar.gz

tar -xzf hyperledger-fabric-linux-amd64-2.3.1.tar.gz

# Move to the bin path
mv bin/* /bin

# Check that you have successfully installed the tools by executing
configtxgen --version

# Should print the following output:
# configtxgen:
#  Version: 2.3.1
#  Commit SHA: 2f69b4222
#  Go version: go1.14.12
#  OS/Arch: linux/amd64

Launching the network

./fabricOps.sh start

Create the namespace and launch the workload:

kubectl create ns hyperledger
kubectl create -f orderer-service/
kubectl create -f org1/
kubectl create -f org2/

Configure the network

peer channel create -o orderer0:7050 -c mychannel -f ./scripts/channel-artifacts/channel.tx --tls true --cafile $ORDERER_CA
peer channel join -b mychannel.block
peer channel fetch 0 mychannel.block -c mychannel -o orderer0:7050 --tls --cafile $ORDERER_CA

Package the chaincode information for the peer and install it

cd chaincode/packaging
tar cfz code.tar.gz connection.json
tar cfz marbles-org1.tgz code.tar.gz metadata.json
peer lifecycle chaincode install marbles-org1.tgz

Build and deploy the chaincode

docker build -t chaincode/marbles:1.0 .
kubectl create -f chaincode/k8s

Approve the chaincode and commit it to the channel

peer lifecycle chaincode approveformyorg --channelID mychannel --name marbles --version 1.0 --init-required --package-id marbles:d8140fbc1a0903bd88611a96c5b0077a2fdeef00a95c05bfe52e207f5f9ab79d --sequence 1 -o orderer0:7050 --tls --cafile $ORDERER_CA

peer lifecycle chaincode checkcommitreadiness --channelID mychannel --name marbles --version 1.0 --init-required --sequence 1 -o -orderer0:7050 --tls --cafile $ORDERER_CA

peer lifecycle chaincode commit -o orderer0:7050 --channelID mychannel --name marbles --version 1.0 --sequence 1 --init-required --tls true --cafile $ORDERER_CA --peerAddresses peer0-org1:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1/peers/peer0-org1/tls/ca.crt --peerAddresses peer0-org2:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2/peers/peer0-org2/tls/ca.crt
