I tried two different tutorials:
This one to deploy docker images locally: https://github.com/hyperledger/fabric-samples I tried the fabcar sample. Everything works fine. I'm able to enroll the admin, register a user and invoke transactions using this user identity. Nice.
The second one to deploy a fabric composer playground on bluemix: https://ibm-blockchain.github.io/setup/ I was able to get into the composer playground and deploy business network examples. I'm also able to upload and deploy my own business networks I designed locally with composer-cli. I exposed the network over a Rest Server with admin rights in order to test the transactions. All works fine.
Now it comes to my problem. I want to combine both examples (just for fun, learning by doing:)). I want to deploy the fabcar samples network to the kubernetes environment on bluemix and interact with the network using the fabric node sdk like in example 1. So I made following changes in the scripts/yaml files of example 2:
- adapt the chaincode installation procedure
in the create_all.sh. line 41 (for peer 1) and line 45 (for peer 2). I changed the values of the env variables CHAINCODE_NAME and CHAINCODE_VERSION
echo "=> CREATE_ALL: Running Install Chaincode on Org1 Peer1" CHAINCODE_NAME="fabcar" CHAINCODE_VERSION="1.0" MSP_CONFIGPATH="/shared/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp" PEER_MSPID="Org1MSP" PEER_ADDRESS="blockchain-org1peer1:30110" create/chaincode_install.sh
in the chaincode_install.yaml.base line 16, I changed the path of the chaincode. I forked the https://github.com/hyperledger/fabric and added the fabcar.go chaincode from example 1 to the new repository https://github.com/bigbelette/fabric
command: ["sh", "-c", "git clone https://github.com/bigbelette/fabric $GOPATH/src/github.com/bigbelette/fabric/ && peer chaincode install -n ${CHAINCODE_NAME} -v ${CHAINCODE_VERSION} -p github.com/bigbelette/fabric/examples/chaincode/go/fabcar/"]
- adapt the chaincode instantiation procedure:
in the create_all.sh. line 49. I changed the values of the env variables CHAINCODE_NAME and CHAINCODE_VERSION:
CHANNEL_NAME="channel1" CHAINCODE_NAME="fabcar" CHAINCODE_VERSION="1.0" MSP_CONFIGPATH="/shared/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp" PEER_MSPID="Org1MSP" PEER_ADDRESS="blockchain-org1peer1:30110" create/chaincode_instantiate.sh
In the chaincode_instantiate.yaml.base, I made the parameter list empty:
command: ["sh", "-c", "peer chaincode instantiate -o blockchain-orderer:31010 -C ${CHANNEL_NAME} -n ${CHAINCODE_NAME} -v ${CHAINCODE_VERSION} -c '{\"Args\":[\"\"]}'"]
The deployment on the cluster works without an error. In the fabcar examples node js file enrollAdmin, regiserUser, query and invoke, I changed the channel name (from mychannel to channel1) and the IPs and ports to match to the online kubernetes services:
enrollAdmin.js and registerUser.js work fine so I can get the certificates and store it in the key store. But when I try to invoke a transaction, i get the following error:
It seems the CA which gave me the certificates is not recognized by the peers. But there is only one CA in my network!? Or is it a problem in the MSP definition (something I still dont understand well).
Thanks for your help.
