如何更快地安装 Hyperledger Fabric java 智能合约（我想避免超时）？
How to make faster Hyperledger Fabric java Smart Contract install (I want to avoid a timeout)?
我正在尝试在 Hyperledger Fabric 上部署 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
终端的错误是：
Error: chaincode install failed with status: 500 - error in
simulation: failed to execute transaction
baeacb6b68dac2872098105d20cb0398e5ce5b744afd37bf75ab65b0ffc7a754:
error sending: timeout expired while executing transaction
监控网络，报错是这样的：

在我看来，下载 gradle 文件花费了太多时间。我的网速不是那么快，但昨天它好几次都运行良好。如果我重新执行命令，那么合约就正确安装了，我想是因为文件已经下载到对等点了。
修改超时限制可能会避免错误，但仍然会花费大量时间安装智能合约。
我对docker了解不多。每次重新启动网络时，有什么方法不会下载 gradle 文件？还有其他方法可以加快安装速度吗？
编辑：打开 Kazam（不录制）是否可能使我的 PC 运行速度变慢（并可能导致超时）？？？？
这就是超级分类帐的工作原理。
1) 您的 Java 代码将是 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位置。
2）下一步将是实例化。在这一步中，真正开始并开始下载所有依赖项的是'gradle build'。
为了加快速度，首先让 'gradle build' 在您的机器上运行。这将导致所有依赖项都被下载到您的“~/.gradle”文件夹中。现在，'COPY' 这个文件夹到 'hyperledger/fabric-javaenv' docker 图像，即我们正在将所有依赖项从您的本地磁盘复制到图像中。这样，就可以避免从 docker 容器内下载。
编辑：
希望您已经克隆了 'fabric samples' 代码。完成后，前往以下位置。正是这段代码从 'cli' 容器中安装并实例化到对等体中。
C:\sw\hlf146-2\fabric-samples\fabcar\java
现在执行 gradle 构建。假设您可以访问互联网并且没有代理相关的麻烦，那么您的构建应该会成功。
C:\sw\hlf146-2\fabric-samples\fabcar\java>gradle build

现在，在上面的图像列表中，HLF 将使用 'hyperledger/fabric-javaenv' 图像从 'cli' 容器中编译您的链代码。我们希望通过您机器的 'c:\users\your-user-name.gradle' 依赖关系来丰富这张图片。此外，在撰写本文时，'hyperledger/fabric-javaenv' 图像使用的是 gradle 4.5 版本，而我想使用最新的 gradle 版本。因此，我也将 gradle 6.3（尽管 Gradle 6.4 在撰写本文时是最新的）也复制到 'hyperledger/fabric-javaenv' 图像。
因此，为此，在一个新文件夹中放入一个名为 'Dockerfile' 的文件（没有文件扩展名），其中包含以下内容（从这里开始，我假设您对 docker，否则，你应该到此为止。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（不是文件夹本身）压缩为 '.gradle.zip' 并将其放在上面的文件夹中。接下来还要放置gradle.zip（这将是下载的gradle软件，当你解压这个gradle.zip时，它应该有gradle-6.3在里面，那将有所有Gradle 软件。您可以在 'Dockerfile' 上面编辑，否则有相应的权限。
因为我 运行 在 windows 上安装了所有这些，所以我在我的机器上安装了 'docker desktop' 并且也选择了 'switch to linux containers'。如果您没有此软件，则需要安装此软件。再次假设您不在代理后面，您将不会遇到所有与代理相关的麻烦，并且 Docker 安装应该是无缝的。
接下来我们需要'build'docker图像使用上面'Dockerfile'.

现在，在上面的图像列表中，HLF 将使用 'hyperledger/fabric-javaenv' 图像从 'cli' 容器中编译您的链代码。我们希望通过您机器的 'c:\users\your-user-name.gradle' 依赖关系来丰富这张图片。此外，在撰写本文时，'hyperledger/fabric-javaenv' 图像使用的是 gradle 4.5 版本，而我想使用最新的 gradle 版本。因此，我也将 gradle 6.3（尽管 Gradle 6.4 在撰写本文时是最新的）也复制到 'hyperledger/fabric-javaenv' 图像。
因此，为此，在一个新文件夹中放入一个名为 'Dockerfile' 的文件（没有文件扩展名），其中包含以下内容（从这里开始，我假设您对 docker，否则，你应该到此为止。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（不是文件夹本身）压缩为 '.gradle.zip' 并将其放在上面的文件夹中。接下来还要放置gradle.zip（这将是下载的gradle软件，当你解压这个gradle.zip时，它应该有gradle-6.3在里面，那将有所有Gradle 软件。您可以在 'Dockerfile' 上面编辑，否则有相应的权限。
因为我 运行 在 windows 上安装了所有这些，所以我在我的机器上安装了 'docker desktop' 并且也选择了 'switch to linux containers'。如果您没有此软件，则需要安装此软件。再次假设您不在代理后面，您将不会遇到所有与代理相关的麻烦，并且 Docker 安装应该是无缝的。
接下来我们需要'build'docker图像使用上面'Dockerfile'.
