No luck.
With:
ec2_config:
instance:
m1.small:
pvdisks:
- /dev/xvdb1
swapvol_size: 2G
logvol_size: 64G
m1.medium:
pvdisks:
- /dev/xvdb1
swapvol_size: 2G
logvol_size: 64G
etc...
and in the manifest:
$foo = hiera_hash('ec2_config')
$pvdisks = $foo['instance'][$::ec2_instance_type]['pvdisks'] #
Line 17 from error below.
notice ("PVDISKS = $pvdisks")
puppet bails with:
err: Could not retrieve catalog from remote server: Error 400 on
SERVER: $foo["instance"] is not an hash or array when accessing it
with m1.large at
/truth/sauce/env/prod/modules/role/manifests/base_server.pp:17 on node
gfs01.us1.xxx.co,
Grrrr.
Doug.
