What is the significance of the default directory under chef cookbook \/templates?<\/div>\n
<\/div>\n
A cookbook is frequently designed to work across many platforms and is often required to distribute a specific template to a specific platform. This is a New in Chef Client 12.0. A cookbook can be designed to support the distribution of templates across platforms, while ensuring that the correct template ends up on each system.<\/div>\n
<\/div>\n

 <\/p>\n

The pattern for template specificity depends on two things: the lookup path and the source. The first pattern that matches is used:<\/strong><\/div>\n
<\/div>\n
\/host-$fqdn\/$source<\/div>\n
\/$platform-$platform_version\/$source<\/div>\n
\/$platform\/$source<\/div>\n
\/default\/$source<\/div>\n
\/$source<\/div>\n
<\/div>\n

 <\/p>\n

Use an array with the source property to define an explicit lookup path. For example:<\/strong><\/div>\n
template ‘\/test’ do<\/div>\n
\u00a0 source [“#{node.chef_environment}.erb”, ‘default.erb’]<\/div>\n
end<\/div>\n
<\/div>\n

 <\/p>\n

The following example emulates the entire file specificity pattern by defining it as an explicit path:<\/strong><\/div>\n
template ‘\/test’ do<\/div>\n
\u00a0 source %W{<\/div>\n
\u00a0 \u00a0 host-#{node[‘fqdn’]}\/test.erb<\/div>\n
\u00a0 \u00a0 #{node[‘platform’]}-#{node[‘platform_version’]}\/test.erb<\/div>\n
\u00a0 \u00a0 #{node[‘platform’]}\/test.erb<\/div>\n
\u00a0 \u00a0 default\/test.erb<\/div>\n
\u00a0 }<\/div>\n
end<\/div>\n
<\/div>\n

 <\/p>\n

A cookbook may have a \/templates directory structure like this:<\/strong><\/div>\n
\/templates\/<\/div>\n
\u00a0 windows-6.2<\/div>\n
\u00a0 windows-6.1<\/div>\n
\u00a0 windows-6.0<\/div>\n
\u00a0 windows<\/div>\n
\u00a0 default<\/div>\n
<\/div>\n

 <\/p>\n

and a resource that looks something like the following:<\/strong><\/div>\n
template ‘C:\\path\\to\\file\\text_file.txt’ do<\/div>\n
\u00a0 source ‘text_file.txt’<\/div>\n
\u00a0 mode ‘0755’<\/div>\n
\u00a0 owner ‘root’<\/div>\n
\u00a0 group ‘root’<\/div>\n
end<\/div>\n
<\/div>\n

 <\/p>\n

This resource would be matched in the same order as the \/templates directory structure. For a node named host-node-desktop that is running Windows 7, the second item would be the matching item and the location:<\/strong><\/div>\n
\/templates<\/div>\n
\u00a0 windows-6.2\/text_file.txt<\/div>\n
\u00a0 windows-6.1\/text_file.txt<\/div>\n
\u00a0 windows-6.0\/text_file.txt<\/div>\n
\u00a0 windows\/text_file.txt<\/div>\n
\n

\u00a0 default\/text_file.txt<\/p>\n
