[chef] Re: passing attributes to recipes

[Brad Montgomery < >]

Hi Steffen,

I'm also fairly new to Chef, but I've been doing this with data bags. You might create a data bag called "build_info", and it might contain an item called "build01".  That item would then list the file names or build numbers that you want.

Then, in your Role, create an attribute that lists the data bag items you want to use in your recipe:  

default_attributes(

  "build_items" => ['build01']

)

Then you can write your recipe to search for those data bags and read your information from there.  Then, in the future, you just create new data bags and roles for nodes that need different info.

In your recipe:

node['build_items].each do |item_name|

  search(:build_info, "id:#{item_name}") do |build|

    # Depending on what your data bag looks like you might

    # reference something like build["filename"] or build["number"]

  end

end

Hope that helps.

Hello,

 

 

I’m relatively new to chef and I try to figure out, how to pass variable attributes like build file names or build numbers to chef recipes. So the best would be if I could add/overwrite a given attribute in a role/environment by it to knife via command line like: knife environment edit [env_name] “attribute_key=attribute_value”.

 

Is there a recommended way of doing that?

 

Thanks in advance,

Steffen
