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/amd64Launching the network
./fabricOps.sh startCreate 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
