Hi Yoshi

Unfortunately, no. Even if it did I cannot modify anything related to base ( due to process/policy/politics/etc)

If I could, then many options would open up .

Thank you for your suggestion.

Does your config type support including? Because you could keep the app portion separate and only include it if a certain attribute is set in the base template (which would only be set in the app cookbook).

So something like

Base:

attributes: default['myconf']['include_app'] = false

template:

<%= "include './my.app.conf'" if node['myconf']['include_app'] %>

App:

attributes: default['myconf']['include_app'] = true
and deploy your app config to the same directory as the base conf.

Hi Dang

I did see the article you refer to.

If I am not mistaken , it talks about replacing templates in a wrapper cookbook.

I was wondering, if I can merge the template in base with the template in the wrapper cookbook.

So final output would be 

final_conf = base_temp.conf + app_temp.conf

Is template merging possible?

You’d want to wrap your base cookbook in the app cookbook. Since you’ve already setup the dependency, your next step is to override the template source being referenced by the template resource. Julian Dunn wrote up a nice blog, entitled “Doing Wrapper Cookbooks Right” and addresses exactly how to specify a different template as the source from a wrapper cookbook.

Hi 

 

I have a base cookbook and a app cookbook which depends on base.

 

The base cookbook has a template - base_temp.conf.erb which gets used inside the app cookbook

 

app_cookbook/recipe/default.rb has include_recipe 'base'

 

Is there a way to append to the base template within app cookbook without modifying the template in the base cookbook as it is applicable only to this one app.

 

So can I have a app_temp.conf.erb which gets appended to the base_temp.conf in the recipe or maybe get the resource collection and append line by line to the base_temp.conf

 

I can get the template resource in the app recipe like so

 

run_context.resource_collection.lookup(
  "template[#{base_template}]")
 
But I dont know if any of the above is correct.
 
Any pointers would be appreciated?
 
Regards
