Question

我试图在程序中读取一个docker文件作为模板，并在发生新情况时替换细节。但是当我使用dump函数时，它失败了。我的代码就像：

    let yaml  = require('js-yaml');
    let filePath = **/docker-compos-template.yaml';
    let savePath = '**/docker-compose-save.yaml';
    try{
        let doc = yaml.safeLoad(fs.readFileSync(filePath),'utf8');
        console.log(doc);
        fs.writeFileSync(savePath, yaml.dump(doc), 'utf8');
    }catch(e) {
        console.log(e);
    }

我的模板文件的一部分是：

 environment:
      - FABRIC_CA_HOME=/etc/hyperledger/fabric-ca-server
      - FABRIC_CA_SERVER_CA_NAME=ca-santai
      - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=chembean_default
      - FABRIC_CA_SERVER_TLS_ENABLED=true
      - FABRIC_CA_SERVER_TLS_CERTFILE=/etc/hyperledger/fabric-ca-server-config/ca.santai.chembean.io-cert.pem

，翻译后的文件是：

    environment:
      - FABRIC_CA_HOME=/etc/hyperledger/fabric-ca-server
      - FABRIC_CA_SERVER_CA_NAME=ca-santai
      - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=chembean_default
      - FABRIC_CA_SERVER_TLS_ENABLED=true
      - >-
        FABRIC_CA_SERVER_TLS_CERTFILE=/etc/hyperledger/fabric-ca-server-config/ca.santai.chembean.io-cert.pem

符号>-未在模板中定义。然后将在翻译文件中为''。 e.g我的模板文件是：

environment:
      - CORE_LEDGER_STATE_STATEDATABASE=CouchDB
      - CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb-santai:5984

      - CORE_PEER_ID=peer0.santai.chembean.io
      - CORE_PEER_NETWORKID=chembean
      - CORE_PEER_ADDRESS=peer0.santai.chembean.io:7051
      - CORE_PEER_GOSSIP_BOOTSTRAP=peer0.santai.chembean.io:7051
      - CORE_PEER_ADDRESSAUTODETECT=true
      - CORE_PEER_CHAINCODEADDRESS=peer0.santai.chembean.io:7052
      - CORE_PEER_CHAINCODELISTENADDRESS=0.0.0.0:7052
      - CORE_CHAINCODE_STARTUPTIMEOUT=1200s
      - CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.santai.chembean.io:7051
      - CORE_PEER_LOCALMSPID=SantaiMSP
      - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
      # 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=chembean_default
      - CORE_LOGGING_LEVEL=INFO
      #- CORE_LOGGING_LEVEL=DEBUG
      - 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

但翻译文件是：

    environment:
      - CORE_LEDGER_STATE_STATEDATABASE=CouchDB
      - 'CORE_LEDGER_STATE_COUCHDBCONFIG_COUCHDBADDRESS=couchdb-santai:5984'
      - CORE_PEER_ID=peer0.santai.chembean.io
      - CORE_PEER_NETWORKID=chembean
      - 'CORE_PEER_ADDRESS=peer0.santai.chembean.io:7051'
      - 'CORE_PEER_GOSSIP_BOOTSTRAP=peer0.santai.chembean.io:7051'
      - CORE_PEER_ADDRESSAUTODETECT=true
      - 'CORE_PEER_CHAINCODEADDRESS=peer0.santai.chembean.io:7052'
      - 'CORE_PEER_CHAINCODELISTENADDRESS=0.0.0.0:7052'
      - CORE_CHAINCODE_STARTUPTIMEOUT=1200s
      - 'CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.santai.chembean.io:7051'
      - CORE_PEER_LOCALMSPID=SantaiMSP
      - 'CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock'
      - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=chembean_default
      - CORE_LOGGING_LEVEL=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

似乎符号''，随机出现。有没有什么好主意，帮我解决这些问题呢？

解析和转储yaml文件时可能会出现问题。如果您可以使用replace-in-files替换yaml文件中的某些字符串。只需将<>放在需要替换文本的位置并相应地放置它们。

不规则的符号时会发生转换搬运工YAML文件
