What is a BlockChain? BlockChain is a distributed database that maintains a continuously-growing list of ordered records called blocks. This technology underlying and other cryptocurrencies. It is a public ledger of all Bitcoin transaction. These blocks are added in a chronological order. In order to deploy a blockchain application, you need a distributed Hyperledger blockchain on your choice of infrastructure (on-premise or cloud). Bitcoin In this article, we will deploy a Hyperledger Fabric cluster using . Kubernetes Prerequisites To follow this guide you need a system with working kubernetes cluster on it. We will use Fabric which is an implementation of blockchain technology written in Golang so go version go1.6.2 or above is required. Before proceeding further let’s have a look on Hyperledger Fabric. The Hyperledger Project Hyperledger is an open source project with collaborative effort created to advance blockchain technology. It helps in cross-industry distributed ledgers which support transaction system, property transaction, and other services. Hyperledger Fabric is an implementation of blockchain technology. It provides a modular architecture allowing pluggable implementations of the various function. The Fabric Setting Hyperledger Cluster on Kubernetes Hyperledger Kubernetes Replication Controller We will launch hyperledger on kubernetes as a Replication Controller it will ensure us the high — availability of hyperledger pods. Create a file named membersrvc-rc.yml. apiVersion: v1 kind: ReplicationController metadata: creationTimestamp: null labels: service: membersrvc name: membersrvc namespace: default spec: replicas: 1 selector: service: membersrvc template: metadata: creationTimestamp: null labels: service: membersrvc spec: containers: - command: - membersrvc image: hyperledger/fabric-membersrvc imagePullPolicy: "" name: membersrvc ports: - containerPort: 7054 resources: {} restartPolicy: Always serviceAccountName: "" volumes: null status: replicas: 0 In the same way, create another file vp0-rc.yml apiVersion: v1 kind: ReplicationController metadata: creationTimestamp: null labels: service: vp0 name: vp0 namespace: ${NAMESPACE} spec: replicas: 1 selector: service: vp0 template: metadata: creationTimestamp: null labels: service: vp0 spec: containers: - command: - sh - -c - sleep 5; peer node start --peer-chaincodedev env: - name: CORE_PEER_ADDRESSAUTODETECT value: "true" - name: CORE_VM_ENDPOINT value: unix:///var/run/docker.sock - name: CORE_LOGGING_LEVEL value: DEBUG - name: CORE_PEER_ID value: vp0 - name: CORE_PEER_PKI_ECA_PADDR value: membersrvc:7054 - name: CORE_PEER_PKI_TCA_PADDR value: membersrvc:7054 - name: CORE_PEER_PKI_TLSCA_PADDR value: membersrvc:7054 - name: CORE_SECURITY_ENABLED value: "false" - name: CORE_SECURITY_ENROLLID value: test_vp0 - name: CORE_SECURITY_ENROLLSECRET value: MwYpmSRjupbT image: hyperledger/fabric-peer imagePullPolicy: "" name: vp0 ports: - containerPort: 7050 - containerPort: 7051 - containerPort: 7053 resources: {} restartPolicy: Always serviceAccountName: "" volumes: null status: replicas: 0 That’s enough with replication controller. Now our next target is to deploy services for the Replication Controller. Create a file called membersrvc-srv.yml apiVersion: v1 kind: Service metadata: creationTimestamp: null name: membersrvc namespace: default spec: ports: - name: "" nodePort: 0 port: 7054 protocol: "" targetPort: 0 selector: service: membersrvc status: loadBalancer: {} Create another file vp0-srv.yml apiVersion: v1 kind: Service metadata: creationTimestamp: null name: vp0 namespace: default spec: type: NodePort ports: - name: "port1" port: 7050 protocol: "" targetPort: 0 - name: "port2" nodePort: 0 port: 7051 protocol: "" targetPort: 0 - name: "port3" nodePort: 0 port: 7053 protocol: "" targetPort: 0 selector: service: vp0 status: loadBalancer: {} Running Hyperledger Pods After creating all the necessary file, next step is to start these rc pods $ kubectl create -f membersrvc-rc.yml $ kubectl create -f vp0-rc.yml Continue Reading the Full Article at — XenonStack.com/Blog
