Question

我正在尝试使用docker-compose在Linux（RHEL 7）计算机中启动超级账本结构网络。但是，对等容器将在一段时间后退出。在peer容器日志中，我可以看到以下错误。

我怀疑docker容器中可能存在一些dns问题。所以我也尝试过在dns_search: .文件中添加- GODEBUG=netdns=go和docker-compose.yaml。

  peer0.org1.example.com:
    container_name: peer0.org1.example.com
    image: hyperledger/fabric-peer:1.4.4
    dns_search: .
    environment:
      - GODEBUG=netdns=go
      - CORE_PEER_ID=peer0.org1.example.com
      - CORE_PEER_ADDRESS=peer0.org1.example.com:7051
      - CORE_PEER_GOSSIP_BOOTSTRAP=peer1.org1.example.com:7051
      - CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.org1.example.com:7051
      - CORE_PEER_LOCALMSPID=Org1MSP
      - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
      - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=${COMPOSE_PROJECT_NAME}_example
      - FABRIC_LOGGING_SPEC=INFO
      - CORE_PEER_TLS_ENABLED=true
      - CORE_PEER_GOSSIP_USELEADERELECTION=true
      - CORE_PEER_GOSSIP_ORGLEADER=false
      - CORE_PEER_PROFILE_ENABLED=true
      - CORE_PEER_TLS_CERT_FILE=/etc/hyperledger/fabric/tls/server.crt
      - CORE_PEER_TLS_KEY_FILE=/etc/hyperledger/fabric/tls/server.key
      - CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/tls/ca.crt
      - CORE_LEDGER_STATE_STATEDATABASE=CouchDB
      - CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb0:5984
      - CORE_LEDGER_STATE_COUCHDBCONFIG_USERNAME=admin
      - CORE_LEDGER_STATE_COUCHDBCONFIG_PASSWORD=admin

仍然是相同的错误。

Answer 1

1. 检查是否在docker-compose.yaml中定义了沙发数据库容器。

2. 如果已定义，则使该应用程序依赖于对方容器。像

      - CORE_LEDGER_STATE_COUCHDBCONFIG_USERNAME=admin
      - CORE_LEDGER_STATE_COUCHDBCONFIG_PASSWORD=admin
   depends_on:
      - couchdb1
   

3. 检查您的couchdb容器是否已启动。如果没有，请使用docker-compose

上载容器
