如何使用 puppet 安装 yum 软件包组?

除了 exec 之外,puppet 是否有安装 yum 软件包组(例如“开发工具”)的方法?

我今天遇到了类似的要求,但如果事情可以通过任何其他方式解决,我不喜欢执行官。所以我选择了不同的路径并为“yumgroup”编写了一个简单的自定义类型。只需将这些文件放在模块路径中的任何模块中,就是这样:

“模块名/lib/puppet/provider/yumgroup/default.rb”

Puppet::Type.type(:yumgroup).provide(:default) do
  desc 'Support for managing the yum groups'

  commands :yum => '/usr/bin/yum'

  # TODO
  # find out how yum parses groups and reimplement that in ruby

  def self.instances
    groups = []

    # get list of all groups
    yum_content = yum('grouplist').split("\n")

    # turn of collecting to avoid lines like 'Loaded plugins'
    collect_groups = false

    # loop through lines of yum output
    yum_content.each do |line|
      # if we get to 'Available Groups:' string, break the loop
      break if line.chomp =~ /Available Groups:/

      # collect groups
      if collect_groups and line.chomp !~ /(Installed|Available)/
        current_name = line.chomp.sub(/^\s+/,'\1').sub(/ \[.*\]/,'')
        groups << new(
          :name   => current_name,
          :ensure => :present
        )
      end

      # turn on collecting when the 'Installed Groups:' is reached
      collect_groups = true if line.chomp =~ /Installed Groups:/
    end
    groups
  end

  def self.prefetch(resources)
    instances.each do |prov|
      if resource = resources[prov.name]
        resource.provider = prov
      end
    end
  end

  def create
    yum('-y', 'groupinstall', @resource[:name])
    @property_hash[:ensure] == :present
  end

  def destroy
    yum('-y', 'groupremove', @resource[:name])
    @property_hash[:ensure] == :absent
  end

  def exists?
    @property_hash[:ensure] == :absent
  end

end

“模块名/lib/puppet/type/yumgroup.rb”

Puppet::Type.newtype(:yumgroup) do
@doc = "Manage Yum groups

A typical rule will look like this:

yumgroup { 'Development tools':
  ensure => present,
}
"
    ensurable

    newparam(:name) do
       isnamevar
       desc 'The name of the group'

之后,在启用 pluginsync 的情况下运行 puppet 代理,您可以像这样使用自定义类型:

yumgroup {'Base': ensure => present, }

或者:

yumgroup {'Development tools': ensure => absent, }

您可以通过运行来查看安装了哪些组:

puppet resource yumgroup

我在Puppet Type Reference中找不到Package 类型的任何内容,所以我在 Freenode 上的 Puppet IRC 频道上询问(#puppet,奇怪的是),但什么也没得到,所以我认为答案是“还没有”。
