Chef-client –local-mode 返回零长度文件

Chef-client –local-mode 返回零长度文件

由于我最近发现 chef-solo 版本 12 存在问题，我将从 chef-solo 切换到 chef-client -z (--local-mode)，以便在我的计算机上运行 chef。在我的其中一本食谱中，我有一个地方正在从食谱的“文件”子目录中下载一个 499 MB 的 gzip 压缩 tar 文件，然后立即提取该文件。代码如下：

# Retrieve and extract the classic.tgz file
cookbook_file '/usr/local/src/classic.tgz' do
  source 'opt/webdocs/classic.tgz'
  backup false
  owner "root"
  group "root"
  mode 0644
  notifies :run, "execute[untar-classic.tgz]", :immediately
end
execute 'untar-classic.tgz' do
  action :nothing
  command '/bin/tar xmzf /usr/local/src/classic.tgz'
  cwd '/opt/webdocs'
  user "apache"
  group "apache"
end

当它在 chef-client 中运行时，它会给出以下输出：

  * cookbook_file[/usr/local/src/classic.tgz] action create
    - create new file /usr/local/src/classic.tgz
    - update content in file /usr/local/src/classic.tgz from none to e3b0c4
    (no diff)
    - change mode from '' to '0644'
    - change owner from '' to 'root'
    - change group from '' to 'root'
  * execute[untar-classic.tgz] action run

我正在 vagrant box（运行 Ubuntu 14.04）中测试此代码，当我登录到 VM 时，问题显而易见。该文件 /usr/local/src/classic.tgz 没有下载，即使 Chef 中没有抛出错误代码（Chef 尝试运行 untar 命令时会抛出 Chef 错误）。该文件在那里，但长度为零：

$ ls -l /usr/local/src/classic.tgz
-rw-r--r-- 1 root root 0 Dec 22 19:54 /usr/local/src/classic.tgz

我猜测该问题是 chef-zero 服务器超时，当 chef-client 使用 --local-mode 标志运行时，该服务器在后台运行，但我无法找到如何配置 chef-zero 服务器（我假设这是“chef-client --local-mode”的工作方式）。

请给我指出正确的方向。

谢谢！

您可以通过从 chef repo 文件夹chef-client -z运行来独立运行服务器。然后您可以使用诸如检查清单是否正确之类的东西。500MB 绝对是chef-zeroknife cookbook show出色地超过文件大小，我建议通过 进行传输cookbook_file。我会将该文件存储在某个 Web 服务器上（可能是 S3），然后使用remote_file（或s3_file）下载它。这样会更安全，性能也会更好，Chef Server 使用的书架服务器并非为实现最大文件服务性能而设计的。
