chef-infra - 如何在 Chef 中定义和调用数组？

Question

下面是我用来复制许多文件的资源。

['contacts_nagios2.cfg','generic-host_nagios2.cfg','generic-service_nagios2.cfg','hostgroups_nagios2.cfg','services_nagios2.cfg','timeperiods_nagios2.cfg'].each do |file|
  cookbook_file "/etc/nagios3/conf.d/#{file}" do
    source  "#{file}"
    mode '0644'
  end
end

我们可以定义['contacts_nagios2.cfg','generic-host_nagios2.cfg','generic-service_nagios2.cfg','hostgroups_nagios2.cfg','services_nagios2.cfg','timeperiods_nagios2.cfg'] 作为同一配方中的一个属性？

Answer 1

这将创建一个数组类型的属性，并且可以在配方文件中定义:

node.default['nagios_config_files']=['contacts_nagios2.cfg','generic-host_nagios2.cfg','generic-service_nagios2.cfg','hostgroups_nagios2.cfg','services_nagios2.cfg','timeperiods_nagios2.cfg']

如果你想添加，你可以稍后做:

node.default['nagios_config_files']|=['more_configs.cfg','even_more_configs.cfg']

(注意“=”符号前的竖线“|”。)

然后你可以像以前一样使用属性:

node['nagios_config_files'].each do |file|
  cookbook_file "/etc/nagios3/conf.d/#{file}" do
    source  "#{file}"
    mode '0644'
  end
end
