"Error: No valid response from any peers" when executing composer network install on custom fabric network

Question

我目前正在为我正在处理的 Hyperledger Composer 项目设置自定义 Hyperledger Fabric 网络。

Composer 文件已经可以使用提供的开箱即用的开发结构服务器完美运行，即 ./startFabric.sh。我遵循了 tutorial 关于如何使用给定的 byfn.sh 将现有业务网络部署到多组织情况，并且网络已成功安装（composer network install ... 成功安装了 .bna 在结构网络上）。

现在我尝试修改 byfn.sh 以支持 3（三）个组织，每个组织只有一个对等体。其他文件（crypto-config.yaml, configtx.yaml, scripts/script.sh 和 docker 撰写文件）也相应修改。

script/script.sh 中的 e2e 测试实际上运行成功（直到出现 "END" ASCII 艺术），这让我认为 fabric 网络已成功设置。 docker ps 命令还 shows docker 容器是运行.

但是，当我尝试在设置结构上执行 composer network install 时，它会输出以下内容：

$ composer network install -c PeerAdmin@example-org1 -a stockchainz.bna
✖ Installing business network. This may take a minute...
Error: Error trying install business network. Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: Failed to connect before the deadline
Command failed

为什么会出现这个错误，即使端到端测试运行良好？我怀疑 connection.json file 不知何故配置错误，因为 e2e运行得很好（“INSERT_..._CA_CERT”和 "INSERT_ORG_NAME" 已经替换为正确的值）

通过日志挖掘，我发现grpc找不到对等点。事实证明这是一个证书问题，我的怀疑是正确的。设置 GRPC_VERBOSITY=DEBUG 显示 re-executing composer network install:

时的日志

...
D0507 12:21:21.934229064   14853 security_handshaker.cc:127] Security handshake failed: {"created":"@1557231681.934207000","description":"Peer name localhost is not in peer certificate","file":"../deps/grpc/src/core/lib/security/security_connector/security_connector.cc","file_line":780}
...

connection.json 将所有对等点的 url 设置为 grpcs://localhost:<port>。而不是这个：

...
"peer0.org1.example.com": {
    "url": "grpcs://localhost:7051",
    "tlsCACerts" : {
        "pem": "INSERT_ORG1_CA_CERT"
    }
},
...

我改成了这样：

...
"peer0.org1.example.com": {
    "url": "grpcs://localhost:7051",
    "grpcOptions": {
        "ssl-target-name-override": "peer0.org1.example.com"
     },
    "tlsCACerts" : {
        "pem": "INSERT_ORG1_CA_CERT"
    }
},
...

这样做之后，业务网络存档安装成功：
