New function "ensure_resources()" to support passing hash as parameter OR from hiera backend
This new function is extension of ensure_resource() which will now support to pass multiple values as hash/array OR from hiera backend variables in title argument with additional parameters needed.
It will
process multiple values for a resource type from the passed argument & pass each entry (type, title, params) to ensure_resource() in required format for further processing.
Now user can have duplicate resource check functionality extended to multiple entries with this new function.
Use:
For multiple resources using
hash:
ensure_resources('user', {'dan' => { gid => 'mygroup', uid =>'600' } , 'alex' => { gid => 'mygroup' }}, {'ensure' =>'present'})
From Hiera Backend:
userlist:
dan:
gid: 'mygroup'
uid: '600'
alex:
gid: 'mygroup'
Call:
ensure_resources('user',hiera_hash('userlist'), {'ensure' => 'present'})
ensure_packages()
Modified to also support Hash type argument for packages
This modification will call newly added ensure_resources() for processing Hash as second argument.
The original functionality remains same for Array type arguments.
Use:
hiera:
packagelist:
ksh:
ensure: latest
mlocate: {}
myrpm:
provider: rpm
source: "/tmp/myrpm-1.0.0.x86_64.rpm"
install_options:
--prefix:
/users/home
openssl:
provider: rpm
source: "/tmp/openssl-1.0.1e-42.el7.x86_64.rpm"
Call:
ensure_packages($packagelist)
