Add ensure_resources() function
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)
