我正在尝试在 Linux (RHEL 7) 机器中使用docker-compose. 但是对等容器会在一段时间后退出。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。所以我也尝试在文件中添加dns_search: .和。- GODEBUG=netdns=godocker-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_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

它仍然是同样的错误。

  1. 检查您是否在 docker-compose.yaml 中定义了 couchdb 容器。

  2. 如果你已经定义了 couchdb 对对等容器的依赖。就像是

       - 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 启动容器
