How to change the name of an attribute with an attribute?

Van_Fossan_Randy · February 2, 2012, 9:08pm

Does anyone know how to change the “name of an attribute” with an
attribute? I know that sounds silly, but I want to subscribe to a set
of repos based on the platform version and the environment that the
server is in.

The attributes from the /attributes folder are:

default[:repo][:my_centos][:updates_prd_5x] =
“http://repo_centos5_prod…”

default[:repo][:my_centos][:updates_prd_6x] =
“http://repo_centos6_prod…”

default[:repo][:my_centos][:updates_dev_5x] =
“http://repo_centos5_dev…”

default[:repo][:my_centos][:updates_prd_6x] =
“http://repo_centos6_dev…”

In a recipe, I have tried variations of the following:

If server is prod…

Update_Repo =
node[:repo][:my_centos][:updates_prd_{node[:platform_version].to_i}x]

if server is dev…

Update_Repo =
node[:repo][:my_centos][:updates_dev_{node[:platform_version].to_i}x]

I cannot get the syntax down correctly. Although, I suspect it may be
more of how chef is handling the attributesd in the Compile Resource
Collection phase of a chef run…

I have different repos for each of my environments (dev, test, prod, QA,
stage1, personal) and different versions of centos for each of these.
Each points to a specific internal url.

Anyone have any ideas?

AJ meant that you can use Hash syntax or regular ruby method syntax.

node[:foo][:bar] is the same as node.foo.bar

another way is

prod_key = :"updates_prd_#{node[:platform_version].to_i}x"
dev_key = :"updates_dev_#{node[:platform_version].to_i}x"

Update_Repo = node[:repo][:my_centos][key_prod]
or
Update_Repo = node[:repo][:my_centos][key_dev]
