[chef] Re: Re: Re: Re: Re: Re: Understanding node attributes set from 'role' cookbooks

[Torben Knerr < >]

The key here for me was that cookbook attributes files are all
evaluated in their entirety before recipes are evaluated, hence any
login in attributes files cannot be manipulated from recipes.

FYI: you can still reload the attributes file from within a recipe, see here:

http://docs.opscode.com/essentials_cookbook_recipes.html#reload-attributes

For example:

```

# override some node attributes here

node.set ....

# re-evaluate attributes files whose attributes are computed based on the ones above

node.from_file(run_context.resolve_attribute("postfix", "default"))

# include actual recipes which need the attributes

include_recipe 'postfix::default'

include_recipe 'postfix::sasl_auth'

```

Maybe this works in your situation as well?

HTH, Torben

 

Many thanks for the help guys.
