Hiera Environment Wildcard

[phundisk]

I am looking to use hiera in my environment but I cannot get past one thing. In our current puppet code we have some case statements based on environments.  The case statements are like the following...

'production' { do this }

/^aw/ { do this } # this is for all AWS stuff

'aws' { do this } # this is the production like environment of AWS

otherenv { do this }

default { do this } # other server that default here

I would like hiera to do the following order, hostname, environment, common.  I would also like to create one YAML file for all the AW* fîles rather than create one for awtest, awsandbox, awetc.  Is there a way to do this in hiera that I am missing?  Or will I need to re work some logic in my puppet code?

I don't think there's a wildcard match functionality for hiera like that. If you interpolate the environment variable in you hierarchy, it will try to match the result exactly.

On the other hand, if all of you "aw*" environments need the same data, I'm inclined to ask what they're doing in different environments?

So right now we use environment to both control specialized parameters related to different networks such as LDAP server, DNS servers, and other things that are related to the environment variable.  We also use unique environment names to setup different instances of our application.  For example, the environment sandbox, will create a version of our application that is configured as in app-sandbox, sprint will create an environment that is like app-sprint. (there are more configurations that this takes care of beyond the naming), AWSandbox will create one related to AWSandbox.

ENVS

sandbox, sprint, qaprod = office network

awsprint, awsandbox, awqaprod = AWS env

production = production network

Part of the original thinking of puppet design was to only handle the setups of these unique instances of our application (as we had multiple puppet servers per environment  BLAH ), the network environment based cases which set LDAP servers and other settings came after. 

So in reality, I have three main environments: office, aws, and production and I need multiple sub environments per environment due to application module we wrote.  Makes me want to do some re-writing of our application''s puppet module or maybe at least set another parameter within the host called like 'appEnv' or something.
