puppet - 在使用 Puppet 安装其他软件包之前运行 `apt-get update`

Question

我正在尝试创建自动安装 zend server CE 的 puppet 模块，这在这里并不重要，但步骤如下

1. 更新/etc/apt/source.list
2. 通过 wget 下载存储库 key
3. 执行 apt-get 更新
4. 执行 apt-get install zend-server-ce-5.2

我有init.pp文件

class zendserverce {

# https://github.com/puppetlabs/puppetlabs-stdlib
file_line { 'debian_package':
    path => '/etc/apt/sources.list',
    line => 'deb http://repos.zend.com/zend-server/deb server non-free'
}

exec { "wget http://repos.zend.com/zend.key -O- |apt-key add -":
    path => ["/usr/bin", "/usr/sbin"]
}

exec { "apt-get update":
    command => "/usr/bin/apt-get update",
    onlyif  => "/bin/sh -c '[ ! -f /var/cache/apt/pkgcache.bin ] || /usr/bin/find /etc/apt/* -cnewer /var/cache/apt/pkgcache.bin | /bin/grep . > /dev/null'",
}

package { "zend-server-ce-php-5.2":
    ensure => "latest"
}

}

似乎 puppet 以与我需要的不同顺序运行命令。有什么办法告诉他按照我想要的顺序运行吗？

该代码片段的输出是

  [0;36mnotice: /Stage[main]/Mc/Package[mc]/ensure: ensure changed 'purged' to 'latest'[0m
  [1;35merr: /Stage[main]/Zendserverce/Package[zend-server-ce-php-5.2]/ensure: change from purged to latest failed: Could not update: Execution of '/usr/bin/apt-get -q -y -o DPkg::Options::=--force-confold install zend-server-ce-php-5.2' returned 100: Reading package lists...
  Building dependency tree...
  Reading state information...
  E: Couldn't find package zend-server-ce-php-5.2 at /tmp/vagrant-puppet/modules 0/zendserverce/manifests/init.pp:28[0m
  [0;36mnotice: /Stage[main]/Zendserverce/Exec[wget http://repos.zend.com/zend.key -O- |apt-key add -]/returns: executed successfully[0m
  [0;36mnotice: /Stage[main]/Zendserverce/File_line[debian_package]/ensure: created[0m
  [0;36mnotice: Finished catalog run in 6.75 seconds[0m

所以它说:找不到包 zend-server-ce-php-5.2

谁能指导我哪里出了问题？

自 Puppet 2.6.0 起，一个新功能“关系语法”是 introduced .

Puppet 2.6.0 及更高版本中的示例如下所示:

exec { "apt-update":
    command => "/usr/bin/apt-get update"
}

Exec["apt-update"] -> Package <| |>

每次执行打包命令时，依赖项(在我们的例子中为“apt-update”)都会首先被触发。您甚至可以定义更长的链。
