Install Chaincode

[jchai002]

How do we install chaincode after setting up the network in this manner? The official hyperledger documentation uses a docker CLI container that can access the peers. But I don't see an equivalent pod in this kubernetes setup.

Hey, I'm facing the same issue. Can you please share if you find a solution?

Hi
@Comonut & @jchai002

I know this might be late, I hope you can still find this useful; but you can setup a fabric tools POD

apiVersion: v1
kind: Pod
metadata:
name: fabric-tools
spec:
volumes:

• name: fabricfiles
  persistentVolumeClaim:
  claimName: your-pvc
• name: dockersocket
  hostPath:
  path: /var/run/docker.sock
  containers:
  • name: fabrictools
    image: hyperledger/fabric-tools:amd64-1.3.0
    imagePullPolicy: Always
    command: ["sh", "-c", "sleep 48h"]
    env:
    • name: FABRIC_CFG_PATH
      value: "/fabric"
      volumeMounts:
      • mountPath: /fabric
        name: fabricfiles
      • mountPath: /host/var/run/docker.sock
        name: dockersocket

1)Apply kubectl apply -f kubernetes/fabric-tools.yaml

2. Then copy your chaincode into your desired folder into the pod; copy your MSP folders too.

3. Install Chaincode
   kubectl exec -it fabric-tools -- /bin/bash
   cp -r /chaincode-folder $GOPATH/src/

export MY_CHAINCODE_NAME="my-chaincode"
export CHAINCODE_VERSION="1.0"
export FABRIC_CFG_PATH="/etc/hyperledger/fabric"
export CORE_PEER_MSPCONFIGPATH="/Path-to-msp"
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_ADDRESS="peer-address:7051"

peer chaincode install -n ${MY_CHAINCODE_NAME} -v ${CHAINCODE_VERSION} -p path-to-chaincode

4. Instantiate Chaincode (After install chaincode on all your peers)
   export ORDERER_URL="orderer-address:7050"
   export MY_CHANNEL_NAME="mychannel"

5. peer chaincode instantiate -o ${ORDERER_URL} -C ${MY_CHANNEL_NAME} -n ${CHAINCODE_NAME} -v ${CHAINCODE_VERSION} -c '{"Args":["Init"]}''

**you can add -P if you wanna setup endorsement policies.
