Hyperledger Fabric Kubernetes peer

Prerequisites

git clone https://github.com/scray/scray.git
cd scray-ledger/containers
kubectl apply -f k8s-hl-fabric-data-share.yaml

Create configuration for new peer

PEER_NAME=peer49
PEER_HOST_NAME=$PEER_NAME.example.scray.org
EXT_PEER_IP=$(kubectl get nodes -o jsonpath="{.items[0].status.addresses[?(@.type=='InternalIP')].address}")

./configure-deployment.sh -n $PEER_NAME

Start service

kubectl apply -f target/$PEER_NAME/k8s-peer-service.yaml

Create peer configuration

GOSSIP_PORT=$(kubectl get service $PEER_NAME -o jsonpath="{.spec.ports[?(@.name=='peer-listen')].nodePort}")
PEER_LISTEN_PORT=$(kubectl get service $PEER_NAME -o jsonpath="{.spec.ports[?(@.name=='peer-listen')].nodePort}")
PEER_CHAINCODE_PORT=$(kubectl get service $PEER_NAME -o jsonpath="{.spec.ports[?(@.name=='peer-chaincode')].nodePort}")

kubectl delete configmap hl-fabric-peer-$PEER_NAME 
kubectl create configmap hl-fabric-peer-$PEER_NAME \
 --from-literal=hostname=$PEER_HOST_NAME \
 --from-literal=org_name=$PEER_NAME \
 --from-literal=sans=peer1.internal.example.com,peer1.external.example.com,peer0.test.s-node.de \
 --from-literal=data_share=hl-fabric-data-share-service:80 \
 --from-literal=ca_country=DE \
 --from-literal=ca_province=Baden \
 --from-literal=ca_locality=Bretten \
 --from-literal=CORE_PEER_ADDRESS=peer0.$PEER_HOST_NAME:$PEER_LISTEN_PORT \
 --from-literal=CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.$PEER_HOST_NAME:$GOSSIP_PORT \
 --from-literal=CORE_PEER_LOCALMSPID=${PEER_NAME}MSP

Start new peer:

kubectl apply -f target/$PEER_NAME/k8s-peer.yaml

Print peer logs

POD_NAME=$(kubectl get pod -l app=$PEER_NAME -o jsonpath="{.items[0].metadata.name}")
kubectl logs -f $POD_NAME  -c $PEER_NAME

Integrate new peer to example network

Example values

ORDERER_IP=10.14.128.30 # Internal IP of orderer
ORDERER_HOSTNAME=orderer.example.com 
CHANNEL_NAME=mychannel
ORG_ID=peer48

Endorse new peer data:

docker exec test-network-cli /bin/bash /opt/scray/scripts/inform_existing_nodes.sh $ORDERER_IP $CHANNEL_NAME $ORG_ID

Integrate new peer to Scray K8s network

Example values

ORDERER_IP=$(kubectl get pods  -l app=orderer-org1-scray-org -o jsonpath='{.items[*].status.podIP}')
ORDERER_HOSTNAME=orderer.example.com 
ORDERER_PORT=30081
# ORDERER_PORT=$(kubectl get service orderer-org1-scray-org -o jsonpath="{.spec.ports[?(@.name=='orderer-listen')].nodePort}")
CHANNEL_NAME=mychannel
SHARED_FS_HOST=10.14.128.38:30080

Endorse new peer data [add to mychannel]:

ORDERER_POD=$(kubectl get pod -l app=orderer-org1-scray-org -o jsonpath="{.items[0].metadata.name}")
kubectl exec --stdin --tty $ORDERER_POD -c scray-orderer-cli  -- /bin/sh /mnt/conf/orderer/scripts/inform_existing_nodes.sh $ORDERER_IP $CHANNEL_NAME $PEER_NAME $SHARED_FS_HOST $EXT_PEER_IP $PEER_HOST_NAME

Join network

 PEER_POD_NAME=$(kubectl get pod -l app=$PEER_NAME -o jsonpath="{.items[0].metadata.name}")
 ORDERER_PORT=$(kubectl get service orderer-org1-scray-org -o jsonpath="{.spec.ports[?(@.name=='orderer-listen')].nodePort}")
 ORDERER_PORT=30081
 PEER_PORT=$(kubectl get service $PEER_NAME -o jsonpath="{.spec.ports[?(@.name=='peer-listen')].nodePort}")
 kubectl exec --stdin --tty $PEER_POD_NAME  -c scray-peer-cli -- /bin/sh /mnt/conf/peer_join.sh $ORDERER_IP  $ORDERER_HOSTNAME $ORDERER_PORT $CHANNEL_NAME $SHARED_FS_HOST $EXT_PEER_IP

Export data

Export channel configuration

Channel configuration can be found here after after the export: $SHARED_FS_HOST/channel/configuration/$CHANNEL_NAME/config.json
kubectl exec --stdin --tty $ORDERER_POD -c scray-orderer-cli -- /bin/sh /mnt/conf/orderer/scripts/publish_channel_conf.sh $CHANNEL_NAME $SHARED_FS_HOST
