连接超时

Question

我在main.go 中 设置router.Run(“0.0.0.0:8088”)，这样从外面可以访问这个url，但是报了这个错误，应该是config.yaml中peer的url 和event url设置不对，我设置是这两个，改成0.0.0.0：7051也是报这样的错误
url: peer0.org1.example.com:7051
# eventUrl is only needed when using eventhub (default is delivery service)
eventUrl: peer0.org1.example.com:7053

event service creation failed: could not get chConfig cache reference: QueryBlockConfig failed: queryChaincode failed: Transaction processing for endorser [peer0.org1.example.com:7051]: Endorser Client Status Code: (2) CONNECTION_FAILED. Description: dialing connection timed out [peer0.org1.example.com:7051]

用docker-compose的话，直接用service的名字加端口访问

  em,老师麻烦可以说的仔细一点吗，没看明白是什么意思

  docker-compose启动的服务间是可以通过服务名互相访问的，因为他们都被限制在同一个网络中了。不明白的话，贴出你的docker-compose文件以及出错的那个配置文件

  这是config.yaml peer的配置信息 
  peers:
    peer0.org1.example.com:
      # this URL is used to send endorsement and query requests
      url: grpc://localhost:7051
      # eventUrl is only needed when using eventhub (default is delivery service)
      eventUrl: grpc://localhost:7053
  
      grpcOptions:
        ssl-target-name-override: peer0.org1.example.com
        # These parameters should be set in coordination with the keepalive policy on the server,
        # as incompatible settings can result in closing of connection.
        # When duration of the 'keep-alive-time' is set to 0 or less the keep alive client parameters are disabled
        keep-alive-time: 0s
        keep-alive-timeout: 20s
        keep-alive-permit: false
        fail-fast: false
        # allow-insecure will be taken into consideration if address has no protocol defined, if true then grpc or else grpcs
        allow-insecure: true
      tlsCACerts:
        # Certificate location absolute path
        path: ./crypto-config/peerOrganizations/org1.example.com/tlsca/tlsca.org1.example.com-cert.pem

改成0.0.0.0 后是连接超时Description: dialing connection timed out [0.0.0.0:7051]，改成本机ip地址也是这个错误CONNECTION_FAILED. Description: dialing connection timed out [192.168.0.101:7051]
