如何让Chef在运行其他配方之前运行apt-get update

Question

现在我的Vagrantfile中有以下内容:

config.vm.provision :chef_solo do |chef|
    chef.cookbooks_path = "cookbooks"
    chef.add_recipe "apt"
    chef.add_recipe "build-essential"
    chef.add_recipe "chef-redis::source"
    chef.add_recipe "openssl"
    chef.add_recipe "git"
    chef.add_recipe "postgresql::server"
    chef.add_recipe "postgresql::client"
end

为了安装添加到我的recipe_list的软件,我需要让VM 在安装其他软件之前发布apt-get更新.

我的印象是,这是'apt'配方的一个特点 - 它会首先运行更新.

我做流浪汉时的输出是:

Answer 1

您可以在一开始就包含apt配方:

include_recipe 'apt'

这将运行更新命令.

Answer 2

apt-get update应该先按照你的方式运行.但是,配方只会每24小时更新一次:

execute "apt-get-update-periodic" do
  command "apt-get update"
  ignore_failure true
  only_if do
    File.exists?('/var/lib/apt/periodic/update-success-stamp') &&
    File.mtime('/var/lib/apt/periodic/update-success-stamp') < Time.now - 86400
  end
end

Answer 3

有三种资源可以在ubuntu系统上很好地完成,特别是在12.04精确64位上使用.

1. 当其他食谱需要时,随意运行apt-get-update

2. 安装update-notifier-common软件包,为我们提供更新时间戳

3. 检查时间戳并定期更新.在这种情况下,在86400秒之后.

这是三个食谱.

execute "apt-get-update" do
  command "apt-get update"
  ignore_failure true
  action :nothing
end

package "update-notifier-common" do
  notifies :run, resources(:execute => "apt-get-update"), :immediately
end

execute "apt-get-update-periodic" do
  command "apt-get update"
  ignore_failure true
  only_if do
   File.exists?('/var/lib/apt/periodic/update-success-stamp') &&
   File.mtime('/var/lib/apt/periodic/update-success-stamp') < Time.now - 86400
  end
end

Answer 4

看起来最新版本的opscode apt cookbook允许您在编译时运行它.

config.vm.provision :chef_solo do |chef|
  chef.cookbooks_path = "cookbooks"
  chef.add_recipe "apt"
  chef.json = { "apt" => {"compiletime" => true} }
end

只要apt在运行列表中的其他编译时间烹饪书(如postgres)之前运行,这应该可行.

我似乎能够通过应用以下补丁来解决该问题：
