How to make faster Hyperledger Fabric java Smart Contract install (I want to avoid a timeout)?
问题
我正试图在Hyperledger Fabric上部署一个Java智能合约，但在执行命令 peer lifecycle chaincode install cp.tar.gz 时遇到超时问题。
终端上的错误信息是：
> 错误：链码安装失败，状态码：500 - 模拟中出错：
> 无法执行交易

发送错误：超时已过期，无法执行交易
通过监视网络，错误的出现如下：

我认为下载那个gradle文件花费了太多时间。我的网络不太快，但昨天它在多次正常工作。如果我重新执行命令，那么合约会正确安装，我认为这是因为文件已经下载到对等端。
修改超时限制可能会避免错误，但安装智能合约仍然需要很长时间。
我对Docker了解不多。是否有一种方式可以在重新启动网络时不必每次下载gradle文件？是否有其他方法可以加快安装速度？
编辑：是否可能打开Kazam（不录制）会使我的电脑变慢（可能导致超时）？

It seems to me that downloading that gradle file is taking too much time. My internet is not so fast, but yesterday it worked fine several times. If I re-execute the command, then the contract is installed correctly, I think because the file is already downloaded into the peer.
Modifying the timeout limit may be avoid the error, but it will still taking a lot of time installing the Smart Contract.
I don't know much about docker. There is some way that the gradle file is not downloaded everytime I restart the network? There is other way to make the install faster?
EDIT: Is it possible that having Kazam open (not recording) make my PC works slower (and perhaps causing timeout)????

这是超级账本（Hyperledger）的工作原理。
1）您的Java代码将作为gradle项目。当您在'cli'容器中触发'install'时，代码将被简单地复制到指定的位置。
2）下一步是实例化。在这一步中，实际上是通过'gradle build'来启动并开始下载所有依赖项。
为了加快这个过程，首先在您的机器上执行'gradle build'。这将导致所有的依赖项都被下载到您的'~/.gradle'文件夹中。现在，将此文件夹'COPY'到'hyperledger/fabric-javaenv' Docker镜像中，即我们正在将所有依赖项从您的本地磁盘复制到镜像中。这样，可以避免在Docker容器内部进行下载。
编辑：
希望您已经克隆了'fabric samples'代码。完成后，转到以下位置。正是这段代码在'cli'容器中安装和实例化到对等体中。
C:\sw\hlf146-2\fabric-samples\fabcar\java
然后执行gradle build。假设您拥有互联网访问权限且没有代理相关的麻烦，您的构建应该成功。
C:\sw\hlf146-2\fabric-samples\fabcar\java>gradle build
为此构建启动了一个新的JVM，以遵守此构建的JVM设置。请考虑使用守护程序: https://docs.gradle.org/6.3/userguide/gradle_daemon.html。

希望您已经在您的计算机上下载了Fabric镜像。不要担心我的输出中的Fabric镜像大小。我在某些输出中可能会看到一些'巨大'的镜像，比如4.58 GB。还可以忽略下面的'dev-peerX.orgX'图像。您将在网络启动时创建它们。
现在在上面的图像列表中，'hyperledger/fabric-javaenv'图像将用于在'cli'容器中从HLF编译您的链码。我们希望在其中添加来自您机器上'c:\users\your-user-name.gradle'的依赖项。此外，在撰写本文时，'hyperledger/fabric-javaenv'图像正在使用gradle 4.5版本，而我希望使用最新的gradle版本。因此，我还将gradle 6.3（尽管在撰写本文时，Gradle 6.4是最新版本）复制到'hyperledger/fabric-javaenv'图像中。
为此，在一个新的文件夹中放置一个名为'Dockerfile'（无文件扩展名）的文件，并具有以下内容（从现在开始，我假设您在Docker方面有一些了解，否则，您应该停在这里。学习一些Docker的基础知识，然后从这里继续）。
FROM hyperledger/fabric-javaenv:1.4
RUN rm -rf /root/.gradle
RUN rm -rf /opt/gradle
ADD ./gradle.zip /opt/
RUN unzip -o /opt/gradle.zip -d /opt/
ADD ./.gradle.zip /root/.gradle/
RUN unzip -o /root/.gradle/.gradle.zip -d /root/.gradle
ENV PATH="/opt/gradle/gradle-6.3/bin:${PATH}"
ENV GRADLE_HOME="opt/gradle/gradle-6.3"
RUN chmod 777 /opt/gradle/gradle-6.3/bin/*
ENV JAVA_HOME="/opt/java/openjdk"
现在将c:\users\your-user-name.gradle文件夹内容（而不是文件夹本身）压缩为'.gradle.zip'，并将其放置在上述文件夹中。接下来，还需要放置gradle.zip（这是下载的gradle软件，当您解压缩gradle.zip时，其中应该有gradle-6.3，并且其中包含所有Gradle软件。您可以相应地编辑上面的'Dockerfile'以进行正确配置）。
由于我在Windows上运行所有这些操作，我在我的计算机上安装了'Docker Desktop'并选择了'switch to linux containers'。如果您没有安装此软件，则需要安装它。再次假设您没有使用代理，您不会遇到代理相关的麻烦，Docker安装应该会很顺利。
接下来，我们需要使用上述'Dockerfile'来'构建' Docker镜像。

英文:
This is how hyper ledger works.
- Your Java code would be gradle project., and when you trigger 'install' in 'cli' container, then the code is simply copied to designated location.
- Next step would be instantiate. In this step, it is 'gradle build' that actually kicks off and starts downloading all dependencies.
In order to expedite this, first get the 'gradle build' work on your machine. This would result into all depeandancies to be downloaded to your '~/.gradle' folder. Now, 'COPY' this folder to 'hyperledger/fabric-javaenv' docker image, i.e. we are copying all dependencies from your local disk into image. This way, a download from within the docker container would be avoided.
EDIT:
Hope you've cloned the 'fabric samples' code. Once done, go the following location. It is this code that gets installed and instantiated from within the 'cli' container into the peers.
C:\sw\hlf146-2\fabric-samples\fabcar\java
Now perform gradle build. Assuming you have internet accessa and no proxy related harrassment, your build should succeed.
C:\sw\hlf146-2\fabric-samples\fabcar\java>gradle build
To honour the JVM settings for this build a new JVM will be forked. Please consider using the daemon: https://docs.gradle.org/6.3/userguide/gradle_daemon.html.
Daemon will be stopped at the end of the build stopping after processing

Hope you have already downloaded fabric images too onto your machine. Dont worry about the sizes of the fabric images in my output below. I was monkeying around and so you see certain images to be 'huge' like 4.58 GB. Also ignore 'dev-peerX.orgX' images below. You'd have them created by the time you get the network UP.

Now in the above image list it is 'hyperledger/fabric-javaenv' image that would be used by HLF to compile your chain code from within the 'cli' container. It is this image that we'd like to enrich with 'c:\users\your-user-name.gradle' dependancies from your machine. Also, at the time of this writing, the 'hyperledger/fabric-javaenv' image was using gradle 4.5 version, and I wanted to use latest gradle version. So, I also copied gradle 6.3 (although Gradle 6.4 was the latest at the time of this writing) too to the 'hyperledger/fabric-javaenv' image.
So for this, in a new folder put a file named 'Dockerfile' (with no file extension) in it with the following contents (from here on I'm assuming you'll have some knowledge on docker, otherwise, you should stop here. Learn some basics of Docker and resume from here).
FROM hyperledger/fabric-javaenv:1.4
RUN rm -rf /root/.gradle
RUN rm -rf /opt/gradle
ADD ./gradle.zip /opt/
RUN unzip -o /opt/gradle.zip -d /opt/
ADD ./.gradle.zip /root/.gradle/
RUN unzip -o /root/.gradle/.gradle.zip -d /root/.gradle
ENV PATH="/opt/gradle/gradle-6.3/bin:${PATH}"
ENV GRADLE_HOME="opt/gradle/gradle-6.3"
RUN chmod 777 /opt/gradle/gradle-6.3/bin/*
ENV JAVA_HOME="/opt/java/openjdk"
Now zip c:\users\your-user-name.gradle folder contents (not the folder itself) as '.gradle.zip' and place it in the above folder. Next also place gradle.zip (this would be gradle software downloaded, and when you unzip this gradle.zip, it should have gradle-6.3 in it, and that would have all of Gradle software. You can edit above 'Dockerfile' to have right accordingly otherwise).
As I'm running all of this on windows, I have 'docker desktop' installed on my machine and selected 'switch to linux containers' too. If you do not have this software, you need to get this installed. Again assuming you are not behind a proxy, you'll not have all of that proxy related harrasment and things should be seamless for Docker installation.
Next we need to 'build' docker image using above 'Dockerfile'.
