Getting started

Requirements

Fabric CA client
YQ binary to replace values in YAML (for the getting started)
KubeCTL
Kubernetes 1.15+
Istio

Install Istio

kubectl apply -f ./hack/istio-operator/crds/*
helm template ./hack/istio-operator/ \
  --set hub=docker.io/istio \
  --set tag=1.8.0 \
  --set operatorNamespace=istio-operator \
  --set watchedNamespaces=istio-system | kubectl apply -f -

kubectl create ns istio-system
kubectl apply -n istio-system -f ./hack/istio-operator.yaml

Installing the operator

Add the helm chartrepository:

helm repo add kfs https://kfsoftware.github.io/hlf-helm-charts --force-update

helm install hlf-operator --version=1.7.0 kfs/hlf-operator

Installing the Kubectl HLF Plugin

To install the Kubectl HLF Plugin, run the following command:

kubectl krew install hlf

To update the Kubectl HLF Plugin to the latest version, run the following command:

 kubectl krew upgrade hlf

Deploy a Peer Organization

Setup versions

export PEER_IMAGE=hyperledger/fabric-peer
export PEER_VERSION=2.4.3

export ORDERER_IMAGE=hyperledger/fabric-orderer
export ORDERER_VERSION=2.4.3

Deploying a Certificate Authority

kubectl hlf ca create --storage-class=standard --capacity=2Gi --name=org1-ca \
    --enroll-id=enroll --enroll-pw=enrollpw  
kubectl wait --timeout=180s --for=condition=Running fabriccas.hlf.kungfusoftware.es --all

# register user for the peers
kubectl hlf ca register --name=org1-ca --user=peer --secret=peerpw --type=peer \
 --enroll-id enroll --enroll-secret=enrollpw --mspid Org1MSP

Deploying a peer

kubectl hlf peer create --statedb=couchdb --image=$PEER_IMAGE --version=$PEER_VERSION --storage-class=standard --enroll-id=peer --mspid=Org1MSP \
        --enroll-pw=peerpw --capacity=5Gi --name=org1-peer0 --ca-name=org1-ca.default
kubectl wait --timeout=180s --for=condition=Running fabricpeers.hlf.kungfusoftware.es --all

Deploying an Ordering Service

Deploying a certificate authority

kubectl hlf ca create --storage-class=standard --capacity=2Gi --name=ord-ca \
    --enroll-id=enroll --enroll-pw=enrollpw
kubectl wait --timeout=180s --for=condition=Running fabriccas.hlf.kungfusoftware.es --all
kubectl hlf ca register --name=ord-ca --user=orderer --secret=ordererpw \
    --type=orderer --enroll-id enroll --enroll-secret=enrollpw --mspid=OrdererMSP

Deploying the Orderer nodes node

kubectl hlf ordnode create --image=$ORDERER_IMAGE --version=$ORDERER_VERSION \
    --storage-class=standard --enroll-id=orderer --mspid=OrdererMSP \
    --enroll-pw=ordererpw --capacity=2Gi --name=ord-node1 --ca-name=ord-ca.default
kubectl wait --timeout=180s --for=condition=Running fabricorderernodes.hlf.kungfusoftware.es --all

Preparing a connection string for the ordering service

kubectl hlf inspect --output ordservice.yaml -o OrdererMSP
kubectl hlf ca register --name=ord-ca --user=admin --secret=adminpw \
    --type=admin --enroll-id enroll --enroll-secret=enrollpw --mspid=OrdererMSP

kubectl hlf ca enroll --name=ord-ca --user=admin --secret=adminpw --mspid OrdererMSP \
        --ca-name ca  --output admin-ordservice.yaml 
## add user from admin-ordservice.yaml to ordservice.yaml
kubectl hlf utils adduser --userPath=admin-ordservice.yaml --config=ordservice.yaml --username=admin --mspid=OrdererMSP

Create a channel

kubectl hlf channel generate --output=demo.block --name=demo --organizations Org1MSP --ordererOrganizations OrdererMSP

# enroll using the TLS CA
kubectl hlf ca enroll --name=ord-ca --namespace=default --user=admin --secret=adminpw --mspid OrdererMSP \
        --ca-name tlsca  --output admin-tls-ordservice.yaml 

kubectl hlf ordnode join --block=demo.block --name=ord-node1 --namespace=default --identity=admin-tls-ordservice.yaml

Preparing a connection string for the peer

kubectl hlf ca register --name=org1-ca --user=admin --secret=adminpw --type=admin \
 --enroll-id enroll --enroll-secret=enrollpw --mspid Org1MSP  

kubectl hlf ca enroll --name=org1-ca --user=admin --secret=adminpw --mspid Org1MSP \
        --ca-name ca  --output peer-org1.yaml

kubectl hlf inspect --output org1.yaml -o Org1MSP -o OrdererMSP

## add user key and cert to org1.yaml from admin-ordservice.yaml
kubectl hlf utils adduser --userPath=peer-org1.yaml --config=org1.yaml --username=admin --mspid=Org1MSP

Join channel

kubectl hlf channel join --name=demo --config=org1.yaml \
    --user=admin -p=org1-peer0.default

Inspect the channel

kubectl hlf channel inspect --channel=demo --config=org1.yaml \
    --user=admin -p=org1-peer0.default > demo.json

Add anchor peer

kubectl hlf channel addanchorpeer --channel=demo --config=org1.yaml \
    --user=admin --peer=org1-peer0.default

See ledger height

In case of error, you may need to add the following to the org1.yaml configuration file:

channels:
  _default:
    orderers:
      - ord-node1.default
    peers:
      "org1-peer0.default":
        endorsingPeer: true
        chaincodeQuery: true
        ledgerQuery: true
        eventSource: true

kubectl hlf channel top --channel=demo --config=org1.yaml \
    --user=admin -p=org1-peer0.default

Install a chaincode

# remove the code.tar.gz asset-transfer-basic-external.tgz if they exist
rm code.tar.gz asset-transfer-basic-external.tgz
export CHAINCODE_NAME=asset
export CHAINCODE_LABEL=asset
cat << METADATA-EOF > "metadata.json"
{
    "type": "ccaas",
    "label": "${CHAINCODE_LABEL}"
}
METADATA-EOF

cat > "connection.json" <<CONN_EOF
{
  "address": "${CHAINCODE_NAME}:7052",
  "dial_timeout": "10s",
  "tls_required": false
}
CONN_EOF

tar cfz code.tar.gz connection.json
tar cfz asset-transfer-basic-external.tgz metadata.json code.tar.gz
export PACKAGE_ID=$(kubectl hlf chaincode calculatepackageid --path=asset-transfer-basic-external.tgz --language=node --label=$CHAINCODE_LABEL)
echo "PACKAGE_ID=$PACKAGE_ID"

kubectl hlf chaincode install --path=./asset-transfer-basic-external.tgz \
    --config=org1.yaml --language=golang --label=$CHAINCODE_LABEL --user=admin --peer=org1-peer0.default

# this can take 3-4 minutes

Deploy chaincode

The following command will create or update the CRD based on the packageID, chaincode name and image.

kubectl hlf externalchaincode sync --image=kfsoftware/chaincode-external:latest \
    --name=$CHAINCODE_NAME \
    --namespace=default \
    --package-id=$PACKAGE_ID \
    --tls-required=false \
    --replicas=1

Query chaincodes installed

kubectl hlf chaincode queryinstalled --config=org1.yaml --user=admin --peer=org1-peer0.default

Approve chaincode

export SEQUENCE=1
export VERSION="1.0"
kubectl hlf chaincode approveformyorg --config=org1.yaml --user=admin --peer=org1-peer0.default \
    --package-id=$PACKAGE_ID \
    --version "$VERSION" --sequence "$SEQUENCE" --name=asset \
    --policy="OR('Org1MSP.member')" --channel=demo

Commit chaincode

kubectl hlf chaincode commit --config=org1.yaml --user=admin --mspid=Org1MSP \
    --version "$VERSION" --sequence "$SEQUENCE" --name=asset \
    --policy="OR('Org1MSP.member')" --channel=demo

Invoke a transaction in the ledger

kubectl hlf chaincode invoke --config=org1.yaml \
    --user=admin --peer=org1-peer0.default \
    --chaincode=asset --channel=demo \
    --fcn=initLedger -a '[]'

Query the ledger

kubectl hlf chaincode query --config=org1.yaml \
    --user=admin --peer=org1-peer0.default \
    --chaincode=asset --channel=demo \
    --fcn=GetAllAssets -a '[]'

At this point, you should have:

Ordering service with 1 nodes and a CA
Peer organization with a peer and a CA
A channel demo
A chaincode install in peer0
A chaincode approved and committed

If something went wrong or didn't work, please, open an issue.

Cleanup the environment

kubectl delete fabricorderernodes.hlf.kungfusoftware.es --all-namespaces --all
kubectl delete fabricpeers.hlf.kungfusoftware.es --all-namespaces --all
kubectl delete fabriccas.hlf.kungfusoftware.es --all-namespaces --all
kubectl delete fabricchaincode.hlf.kungfusoftware.es --all-namespaces --all

Troubleshooting

Chaincode installation/build error

Chaincode installation/build can fail due to unsupported local kubertenes version such as minikube.

$ kubectl hlf chaincode install --path=./fixtures/chaincodes/fabcar/go \
        --config=org1.yaml --language=golang --label=fabcar --user=admin --peer=org1-peer0.default
        
Error: Transaction processing for endorser [192.168.49.2:31278]: Chaincode status Code: (500) UNKNOWN. 
Description: failed to invoke backing implementation of 'InstallChaincode': could not build chaincode: 
external builder failed: external builder failed to build: external builder 'my-golang-builder' failed:
exit status 1

If your purpose is to test the hlf-operator please consider to switch to kind that is tested and supported.
