Is it bad to have a CHEF wrapper cookbook for every environment? -


i new chef, , i'm trying setup cookbooks infrastructure.

i have several types of web servers. have base webserver cookbook, , have 3 wrapper cookbooks. 1 each type of web server.

base

  • web

wrappers

  • web_mail
  • web_scheduled
  • web_hsm

i want setup multiple environments qa , production servers can point different databases. (using variables in .erb templates). want use cookbook version promotion ensure each version tested in stage before production.

  • production
  • stage
  • qa
  • dev

while put database variables in environment attributes, or in roles, this blog, suggests that anti pattern , better use environment wrapper cookbooks.

however, if use environment wrapper cookbooks, have unmanageable 4x3 matrix of cookbooks (13 cookbooks total).

is there way combine wrapper cookbooks, multiple environments?

a better explanation of environment cookbook pattern given here:

"environment" cookbooks same "application" cookbook. idea capture applications logic in 1 place. cookbook attributes capture default settings.

when comes deployment want leverage chef's attribute precedence , override cookbook defaults using chef environment. secondary benefit of using environments can constrain cookbook versions applied @ run-time. means each deployed instance of cookbook customized in single place (the chef environment).

finally roles can used override cookbook attributes, best advised keep number of customization points minimum initially.
