Question

Unable to deploy chaincode example in my local hyperledger fabric.

system config: mac osx, Docker toolbox for mac

One validating peer is up and running using docker-compose.yaml

membersrvc:
  image: hyperledger/fabric-membersrvc
  command: membersrvc
vp0:
  image: hyperledger/fabric-peer
  environment:
    - CORE_PEER_ADDRESSAUTODETECT=false
    - CORE_VM_ENDPOINT=http://172.17.0.1:2375
    - CORE_LOGGING_LEVEL=DEBUG
    - CORE_PEER_ID=vp0
    - CORE_SECURITY_ENROLLID=test_vp0
    - CORE_SECURITY_ENROLLSECRET=MwYpmSRjupbT
  links:
    - membersrvc
  command: sh -c "sleep 5; peer node start --peer-chaincodedev"

While deploying chaincode by running

CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=0.0.0.0:30303 ./test

Its showing the error as [shim] ERRO : Error trying to connect to local peer: grpc: timed out trying to connect

I tried replacing CORE_PEER_ADDRESS as suggested by grep timeout solution but no change in error.

You need to use the correct port number on which peer process is listening to.

instead of using the following command,

CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=0.0.0.0:30303 ./test

try this instead,

CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=0.0.0.0:7052 ./test

if it doesn't work then run the following command to check your listening port and use that instead,

netstat -atp tcp | grep -i "listen"
