hyperledger fabric fabcar error

问题

I tried to run fabcar example from hyperledger-fabric tutorial https://hyperledger-fabric.readthedocs.io/en/latest/write_first_app.html.

when I run ./startFabric.sh I got the error :

    //Join peer0.org1.example.com to the channel.

Usage:
  peer channel join [flags]

Flags:
  -b, --blockpath string   Path to file containing genesis block

Global Flags:
      --cafile string              Path to file containing PEM-encoded trusted certificate(s) for the ordering endpoint
      --logging-level string       Default logging level and overrides, see core.yaml for full syntax
  -o, --orderer string             Ordering service endpoint
      --test.coverprofile string   Done (default "coverage.cov")
      --tls                        Use TLS when communicating with the orderer endpoint
  -v, --version                    Display current version of fabric peer server

when I type 'docker ps' it showed:

I check using port in peer0 : $docker ps -a | grep peer0

Then, I check the logs in each container:

Can anyone tell me why??

Based on the information you have posted in your question, the reason for the error:

Primarily due to the fact that peer container is down, hence peer cli cannot reach endorsing peer and therefore failing. Now the reason it fail, because it cannot reach couchdb:

panic: Error in instantiating ledger provider: Unable to connect to CouchDB, check the hostname and port: Get http://couchdb:5984/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

By looking on docker-compose file in basic-network folder it seems that startup of the peer container is not dependent on couchdb container:

  peer0.org1.example.com:
    container_name: peer0.org1.example.com
    image: hyperledger/fabric-peer:x86_64-1.0.0
    environment:
      - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
      - CORE_PEER_ID=peer0.org1.example.com
      - CORE_LOGGING_PEER=debug
      - CORE_CHAINCODE_LOGGING_LEVEL=DEBUG
      - CORE_PEER_LOCALMSPID=Org1MSP
      - CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/peer/
      - CORE_PEER_ADDRESS=peer0.org1.example.com:7051
      # # the following setting starts chaincode containers on the same
      # # bridge network as the peers
      # # https://docs.docker.com/compose/networking/
      - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=${COMPOSE_PROJECT_NAME}_basic
      - CORE_LEDGER_STATE_STATEDATABASE=CouchDB
      - CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb:5984
    working_dir: /opt/gopath/src/github.com/hyperledger/fabric
    command: peer node start
    # command: peer node start --peer-chaincodedev=true
    ports:
      - 7051:7051
      - 7053:7053
    volumes:
        - /var/run/:/host/var/run/
        - ./crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/msp:/etc/hyperledger/msp/peer
        - ./crypto-config/peerOrganizations/org1.example.com/users:/etc/hyperledger/msp/users
        - ./config:/etc/hyperledger/configtx
    depends_on:
      - orderer.example.com
    networks:
      - basic

The fix should be rather simply, just to add dependency to make sure couchdb is available while running the peer container:

depends_on:
  - orderer.example.com
  - couchdb # <--- Add this line

回答2:

The only solution which worked for me is increasing sleep time to start fabric.Follow the following the procedure

Delete all hyperledger docker images before starting fabric (startFabric.sh will download latest images again).

To delete all containers including its volumes use,
```
docker rm -vf $(docker ps -a -q)
```
To delete all the images,
```
docker rmi -f $(docker images -a -q)
```
open basic-network/start.sh
make FABRIC_START_TIMEOUT=90 (default 10)
./startFabric.sh
