CFEngine 3.5 Oracle承诺

Question

这里是CFEngine 3新手。

我正试图在Ubuntu系统上安装Oracle，我应该如何用CFEngine编写它呢？

我可以使用webupd8team提供的PPA在shell中进行类似的操作。

add-apt-repository ppa:webupd8team/java
apt-get update

echo "Installing JDK 7..."
echo debconf shared/accepted-oracle-license-v1-1 select true | sudo debconf-set-selections
echo debconf shared/accepted-oracle-license-v1-1 seen true | sudo debconf-set-selections
apt-get install -y oracle-java7-installer

我在CFEngine上做这件事完全失败了。到目前为止，我已经：

body common control {
    inputs => { "$(sys.libdir)/stdlib.cf" };
    bundlesequence => { "manage_properties", 
                        "manage_jdk"};
}

bundle agent manage_properties {
    vars:
        "prop_pkgs" slist => {"python-software-properties", "software-properties-common"};
        "cmds"      slist => {  "/usr/bin/add-apt-repository ppa:webupd8team/java",
                                "/bin/echo debconf shared/accepted-oracle-license-v1-1 select true | sudo debconf-set-selections", 
                                "/bin/echo debconf shared/accepted-oracle-license-v1-1 seen true | sudo debconf-set-selections",
                                "/usr/bin/apt-get update" };

    methods:
        "$(prop_pkgs)" 
            handle => "manage_properties",  
            comment => "Make sure required properties packages are installed",
            usebundle => package_latest("$(prop_pkgs)");

    commands:
        "$(cmds)"
            comment => "Firing preinstall commands for JDK";
}

bundle agent manage_jdk {
    methods:
        "JDK" 
            handle => "manage_jdk",
            comment => "Make sure Java is installed",
            usebundle => package_latest("oracle-java7-installer");
}

但是，这个承诺失败了，有以下错误：

2014-06-30T14:11:18+0000    error: /default/manage_jdk/methods/'JDK'/default/package_latest/packages/'oracle-java7-installer'[0]: Finished command related to promiser 'oracle-java7-installer' -- an error occurred, returned 100
2014-06-30T14:11:18+0000    error: /default/manage_jdk/methods/'JDK'/default/package_latest/packages/'oracle-java7-installer'[0]: Bulk package schedule execution failed somewhere - unknown outcome for 'oracle-java7-installer'

会喜欢任何指针的。谢谢

我在您的策略中看到的一件事是，您正在运行一些需要shell (管道命令)的命令，并且您的命令承诺不会包含在任何shell中。

commands: "/bin/echo 'Hello World' | grep Hello" contain => in_shell;

而且，似乎您对预命令采取了一个非常必要的观点。CFEngine通常每5分钟运行一次策略。在必要时，我将更多地关注于执行必要的操作，并试图将重点放在状态而不是行动上。

例如，无条件地运行apt-add-存储库。考虑在什么条件下实际需要执行命令。
