如何使用 cloudfoundry 存储库中的 apt-buildpack

问题描述 投票：0回答：2

apt-buildpack 是实验性的，尚未用于生产用途。我想这就是为什么也没有文档的原因。

您能否举例说明如何推送

cf-env
示例应用程序并安装例如rtorrent和/或openvpn。是否可以安装 gnome 进行测试？

就使用而言，它非常简单，您只需在应用程序的根目录中包含一个 

apt.yml
即可。其中应该包含要安装的软件包列表。

例如：

---
packages:
- ascii
- libxml
- https://example.com/exciting.deb

构建包支持安装包名称、deb 文件、自定义 APT 存储库，甚至 PPA。

请参阅自述文件以获取更多说明。

此消息：

警告：此构建包只能作为供应构建包运行，不能单独运行

告诉您 Apt 构建包仅用于提供二进制文件。它实际上不知道如何运行您的应用程序或任何应用程序。有关供应脚本的更多信息，请查看此处的文档。

使其工作的技巧是您需要使用多构建包支持。可以在此处找到相关说明。这应该适用于大多数应用程序，但有一个简单的示例here。

应用程序暂存并启动后，您可以通过运行 

cf ssh apt-test -t -c "/tmp/lifecycle/launcher /home/vcap/app bash ''"
来确认您的软件包已安装。安装的所有内容都应该位于路径上，但如果您想查看安装内容的位置，它将位于 
/home/vcap/deps/<buildpack-number>/
下。

应该就是这样了。希望有帮助！

接受的答案是正确的，并提供了文档链接，但在这里我想给出一个使用 Maven 进行 WAR 打包的 Spring Boot Java 应用程序的示例。

  1. 在您的 
    manifest.yml
    中，
    buildpacks
    部分应如下所示：
    buildpacks:
      - https://github.com/cloudfoundry/apt-buildpack.git
      - java_buildpack

请注意 

apt-buildpack
：a) 使用 git 存储库，因为它是实验性的 b) 位于构建包列表中的第一个。

  1. 在我的 
    manifest.yml
    中，应用程序工件的路径如下所示：
path: ./target/ROOT.war

因此可以在应用程序构建期间将 

apt.yml
添加到 WAR 文件中。对于 
apt.yml
位于上一级文件夹中 
src
，将构建插件添加到 
pom.xml
应该可以工作：

...
            <build>
                <plugins>
                    <plugin>
                        <artifactId>maven-antrun-plugin</artifactId>
                        <executions>
                            <execution>
                                <id>add-apt.yml</id>
                                <goals>
                                    <goal>run</goal>
                                </goals>
                                <phase>prepare-package</phase>
                                <configuration>
                                    <target>
                                        <copy file="${project.build.directory}/../apt.yml" tofile="${project.build.directory}/ROOT/apt.yml" />
                                    </target>
                                </configuration>
                            </execution>
                        </executions>
                    </plugin>
...
                </plugins>
            </build>

其中

ROOT
是未来
ROOT.WAR
文件的目录。此命令会将 
apt.yml
文件复制到生成 WAR 文件的文件夹中。

  1. apt.yml
    可能看起来像这样：
---
packages:
  - libnss3
  - libnspr4
  - libatk1.0-0
  - libatk-bridge2.0-0
  - libcups2
  - libxkbcommon0
  - libatspi2.0-0
  - libxcomposite1
  - libxdamage1
  - libxrandr2
  - libgbm1
  - libasound2

在此示例中，它放置在应用程序的存储库根目录中，与 

pom.xml
和 
manifest.yml
相同。

  1. 像往常一样运行 
    cf push -f manifest.yml
    ，您应该看到在 Java 构建包启动之前已经安装了 apt 软件包：
