Fabric Composer与Bluemix区块链服务的集成 [英] Fabric composer integration with Bluemix blockchain service

问题描述

今天可以将作曲家结构业务网络.bna文件部署到bluemix区块链服务吗?如果是这样，是否存在某人可以共享的连接配置文件示例?谢谢.

Can a composer fabric business network, .bna file, be deployed to the bluemix blockchain service today? If so, is there a connection profile example that someone can share? Thanks.

推荐答案

您现在可以将Composer与Bluemix Blockchain服务一起使用.

You can use Composer with the Bluemix Blockchain service today.

但是，您必须正在运行Composer Playground的本地副本，因为在Bluemix上运行的Composer版本(fabric-composer.mybluemix.net)目前仅支持Web连接配置文件.

However, you must be running a local copy of the Composer Playground as the version of Composer running on Bluemix (fabric-composer.mybluemix.net) only supports the web connection profile at the moment.

您可以按照以下说明设置Composer Playground的本地副本:

You can set up a local copy of the Composer Playground by following the instructions here: https://fabric-composer.github.io/start/getting-started-playground.html

这是我用来连接到Bluemix Blockchain服务的连接配置文件:

Here's the connection profile that I used to connect to the Bluemix Blockchain service:

URL中的主机名和端口号必须来自Bluemix仪表板.通过导航到服务凭据"并查看默认凭据"Credentials-1"，我发现最容易获得此信息.这是每个URL的来源的解释:

The hostname and port numbers in the URLs must come from the Bluemix dashboard. I find it easiest to get this information by navigating to "Service Credentials" and viewing the default credentials "Credentials-1". Here's an explanation of where each URL comes from:

membershipServicesURL 始终为"grpcs://" +来自"ca"对象的网址(该网址也为Discovery_host +:" + Discovery_port).

membershipServicesURL is always "grpcs://" + url from the "ca" object (url also being discovery_host + ":" + discovery_port).

peerURL 始终是"peers"数组中列出的对等方之一的"grpcs://" + Discovery_host +:" + Discovery_port.

peerURL is always "grpcs://" + discovery_host + ":" + discovery_port from one of the peers listed in the "peers" array.

eventHubURL 始终是对等"数组中列出的对等之一的"grpcs://" + event_host +:" + event_port.

eventHubURL is always "grpcs://" + event_host + ":" + event_port from one of the peers listed in the "peers" array.

keyValStore 是运行Composer的系统文件系统上的目录.如果使用Docker映像，请使用"/home/composer/.composer-credentials"路径，否则请使用计算机上存在的目录.

keyValStore is a directory on the file system of the system running Composer. If using the Docker images, then use the "/home/composer/.composer-credentials" path, otherwise use a directory that exists on your machine.

证书来自"us.blockchain.ibm.com.cert"文件，该文件可以从凭证中的"cert"属性下载，例如"

certificate comes from the "us.blockchain.ibm.com.cert" file which can be downloaded from the "cert" property in the credentials, for example "https://blockchain-certs.mybluemix.net/us.blockchain.ibm.com.cert". If you create this JSON manually, you must ensure that it ends with a "\n" newline character.

certificatePath 来自凭据中的"cert_path"属性.

certificatePath comes from the "cert_path" property in the credentials.

您还可以从凭证页面获取要用于Bluemix的注册ID和注册机密.我建议使用管理员".请注意，如果使用REST API与Bluemix服务进行交互，则不能在Composer中使用这些相同的凭证.

You can also get the enrolment ID and enrolment secret to use for Bluemix from the credentials page; I recommend using "admin". Note that if you use the REST APIs to interact with the Bluemix service then you cannot use those same credentials with Composer.

但是要注意的一件事是，由于活动集线器连接由于不活动而超时，因此Bluemix区块链服务可能不可靠.发生这种情况时，Composer将终止，您可能会看到错误.我们正在等待对hfc(Hyperledger Fabric客户端)Node.js模块的修复，该模块将正确处理此错误并根据需要重新连接.

One thing to note however is that the Bluemix Blockchain service can be unreliable due to problems with the event hub connection being timed out due to inactivity. When this happens, Composer will terminate and you may see an error. We are awaiting a fix to the hfc (Hyperledger Fabric Client) Node.js module that will correctly handle this error and reconnect as required.
