apache-kafka - Hyperledger Fabric First 网络不与 kafka 一起使用并使用 TLS

Question

我尝试运行第一个网络示例 Building Your First Network来自官方文档。我需要使用 kafka orderer 类型运行这个示例。对于这种情况，我编辑 configtx.yaml 文件(将 OrdererType 更改为 kafka 并添加了 Brokers)

...

# Orderer Type: The orderer implementation to start
# Available types are "solo" and "kafka"
OrdererType: kafka

...

 Kafka:
    # Brokers: A list of Kafka brokers to which the orderer connects
    # NOTE: Use IP:port notation
    Brokers:
        - kafka:9093

...

并在 base/docker-compose-base.yaml 中添加了 kafka 和 zookeeper 容器

....

zookeeper:
 image: hyperledger/fabric-zookeeper
 container_name: zookeeper
 ports:
  - 2181:2181
 networks:
  - byfn
kafka:
 image: hyperledger/fabric-kafka
 container_name: kafka
 environment:
  - KAFKA_ADVERTISED_HOST_NAME=kafka
  - KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181
  - KAFKA_SSL_KEYSTORE_LOCATION=/var/private/ssl/kafka.server.keystore.jks
  - KAFKA_SSL_KEYSTORE_PASSWORD=test1234
  - KAFKA_SSL_KEY_PASSWORD=test1234
  - KAFKA_SSL_TRUSTSTORE_LOCATION=/var/private/ssl/kafka.server.truststore.jks
  - KAFKA_SSL_TRUSTSTORE_PASSWORD=test1234
  - KAFKA_LISTENERS=PLAINTEXT://kafka:9092,SSL://kafka:9093
  - KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://kafka:9092,SSL://kafka:9093
  - KAFKA_MESSAGE_MAX_BYTES=103809024
  - KAFKA_REPLICA_FETCH_MAX_BYTES=103809024
  - KAFKA_UNCLEAN_LEADER_ELECTION_ENABLE=false
 volumes:
  - ./sample/server.keystore.jks:/var/private/ssl/kafka.server.keystore.jks
  - ./sample/server.truststore.jks:/var/private/ssl/kafka.server.truststore.jks
 ports:
  - 9093:9093
  - 9092:9092
 networks:
  - byfn

我还为 kafka 客户端和服务器生成了加密数据。

keytool -keystore server.keystore.jks -alias kafka -validity 365 -genkey -keyalg RSA -keysize 2048 -storepass test1234 -dname "cn=kafka" -keypass test1234
keytool -keystore client.keystore.jks -alias orderer -validity 365 -genkey -keyalg RSA -keysize 2048 -storepass test1234 -dname "cn=orderer" -keypass test1234
openssl req -new -x509 -keyout ca-key.pem -out ca-cert.pem -days 365 -subj "/CN=FAB5226" -nodes

openssl pkcs12 -in client.keystore.p12 -nodes -nocerts -out client-key.pem -passin pass:test1234

并更改了 base/docker-compose-base.yaml 中的 orderer 容器配置

orderer.example.com:
 container_name: orderer.example.com
 image: hyperledger/fabric-orderer
 environment:
  - ORDERER_GENERAL_LOGLEVEL=debug
  - ORDERER_GENERAL_LISTENADDRESS=0.0.0.0
  - ORDERER_GENERAL_GENESISMETHOD=file
  - ORDERER_GENERAL_GENESISFILE=/var/hyperledger/orderer/orderer.genesis.block
  - ORDERER_GENERAL_LOCALMSPID=OrdererMSP
  - ORDERER_GENERAL_LOCALMSPDIR=/var/hyperledger/orderer/msp
  # enabled TLS
  - ORDERER_KAFKA_TLS_ENABLED=true
  - ORDERER_KAFKA_TLS_PRIVATEKEY_FILE=/var/private/ssl/client-key.pem
  - ORDERER_KAFKA_TLS_CERTIFICATE_FILE=/var/private/ssl/client-cert-signed.pem
  - ORDERER_KAFKA_TLS_ROOTCAS_FILE=/var/private/ssl/ca-cert.pem
  - ORDERER_KAFKA_VERBOSE=true
  - ORDERER_KAFKA_SERVER=kafka
  - ORDERER_KAFKA_BROKERS=[kafka:9093]
  - ORDERER_GENERAL_TLS_ENABLED=true
  - ORDERER_GENERAL_TLS_PRIVATEKEY=/var/hyperledger/orderer/tls/server.key
  - ORDERER_GENERAL_TLS_CERTIFICATE=/var/hyperledger/orderer/tls/server.crt
  - ORDERER_GENERAL_TLS_ROOTCAS=[/var/hyperledger/orderer/tls/ca.crt]
 working_dir: /opt/gopath/src/github.com/hyperledger/fabric
 command: orderer
 volumes:
  - ../channel-artifacts/genesis.block:/var/hyperledger/orderer/orderer.genesis.block
  - ../crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp:/var/hyperledger/orderer/msp
  - ../crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/:/var/hyperledger/orderer/tls
  - ../sample/ca-cert.pem:/var/private/ssl/ca-cert.pem
  - ../sample/client-cert-signed.pem:/var/private/ssl/client-cert-signed.pem
  - ../sample/client-key.pem:/var/private/ssl/client-key.pem
 ports:
  - 7050:7050

然后我尝试使用以下命令运行示例

./byfn.sh -m up -s couchdb -a

并在脚本尝试创建新 channel 时收到错误消息

Error: got unexpected status: SERVICE_UNAVAILABLE -- cannot enqueue

Error message when the script try to create new channel

请帮我解决这个错误。

我解决了问题。在 cli 容器中运行 script.sh 之前添加了 sleep 30。文件 docker-compose-cli.yaml

command: /bin/bash -c 'sleep 30; ./scripts/script.sh ${CHANNEL_NAME} ${DELAY} ${LANG}; sleep $TIMEOUT'
