[Puppet Users] Replicating += with hiera

2014-03-12 Thread Kenton Brede

I'm in the process of moving to Puppet 3 and hiera.

With my old setup I placed users that were on all servers in basenode.
Then did a += for any additional users in the node definition.

node basenode {
  users = ['user1', 'user2']
}

node server.example.com inherits basenode {
  users += ['user3']
  # or simple exclude the line, if there were no additional users
}

With the new setup I've got a common.yaml that contains a hash of users
with access to all boxes.  Then I thought I'd place additional users for
server1 in server1.yaml.

common.yaml
users_common:
  user1:
ensure: present
home: /home/user1
..

server1.yaml
server1_users:
  user3:
ensure: present
home: /home/user3
..

Then I call like this, which just pulls the usernames from the hash and
creates home directories with a file type:

class users::ldap {
  # regular users
  $users_common = hiera('users_common')
  $users_common_keys = keys($users_common)
  $users_hosts = hiera(${::hostname}_users)
  $users_hosts_keys = keys($users_hosts)
  $adusers_combined = flatten([ $users_common_keys, $users_hosts_keys ])

  # create ldap user home directories
  users::admin_homedir_define { $adusers_combined: }
}

Works great until there are no users for ${::hostname}_users.

How can I make this work when ${::hostname}_users is empty?
Thanks,

Re: [Puppet Users] Replicating += with hiera

2014-03-12 Thread Jonathan Proulx

see http://docs.puppetlabs.com/hiera/1/puppet.html

If you need to merge arrays or merge hashes from multiple hierarchy
levels, you will have to use the hiera_array or hiera_hash functions
in the body of your classes.

There's not really a good example in that page, but essentially where
'hiera' takes the most specific patch hiera_array and heira_hash
collect all the values across all matching hierarchies (though you
needn't define the key in every level)

we use this for packages to install:

  $basepackages = hiera_array('basepackages')
  ensure_packages($basepackages)

Then in hiera be define (or not) arrays of packages by os version, role, etc...

I don't fully understand you problem, but I believe you want to pass a
default value to your hiera call so that it will work in the absence of
the key. E.g.

$users_hosts = hiera(${::hostname}_users, [])

HTH,
Felix

Re: [Puppet Users] Replicating += with hiera

2014-03-12 Thread Kenton Brede

Thanks for the help all. Maybe I'm approaching this in the wrong way but
the example puts all users on each box. I'm trying to do something like:

users_common = admin1, admin2
server1 = users_common + user1
server2 = users_common
server3 = users_common + user1, user3

The goal is to not have to list the admin users in each host.yaml file, but
include them.

From what I gather hiera doesn't allow:

sever1.yaml
include users_common

server1_users:
user1:
ensure: present
home: /home/user1

Thanks,
Kent

in stead of using users_common and server1_users just call both 'users':

users:

 ensure: present
 home: /home/user1
 ..

 server1.yaml
 users:
   user3:

 Then I call like this, which just pulls the usernames from the hash and
 creates home directories with a file type:

 class users::ldap {
   # regular users
   $users_common = hiera('users_common')
   $users_common_keys = keys($users_common)
   $users_hosts = hiera(${::hostname}_users)

   $adusers_combined = flatten([ $users_common_keys, $users_hosts_keys ])

   # create ldap user home directories
   users::admin_homedir_define { $adusers_combined: }
 }

You can then collect all the users with hiera_hash('users') rather
than fussing with seperate $users_common and $users_hosts

 class users::ldap {
   # regular users
   $users = hiera('users')
   $users_keys = keys($users)

   # create ldap user home directories
   users::admin_homedir_define { $users_keys: }
 }

Note I just copy pasted your code example  substituted syntax didn't
test, seems a bit odd that you're operating on just the keys not the
collected hash but left that as is since I don't knwo what it's
ultimately being fed to.
