Create a symlink using puppet programming

 Task:

Create a puppet programming file apps.pp under /etc/puppetlabs/code/environments/production/manifests directory on puppet master node i.e on Jump Server. Within that define a class symlink and perform below mentioned tasks:
Create a symbolic link through puppet programming code. The source path should be /opt/data and destination path should be /var/www/html on all Puppet agents i.e on all App Servers.
Create a blank file media.txt under /opt/data directory on all puppet agent nodes i.e on all App Servers.
Note: Please perform this task using apps.pp only, do not create any separate inventory file.

Step 1) Create puppet class file apps.pp on jump host where puppet master is running

root@jump_host /# cd /etc/puppetlabs/code/environments/production/manifests
root@jump_host /etc/puppetlabs/code/environments/production/manifests# cat>apps.pp 
class symlink {
# create a symlink
 file { '/opt/data/':
      ensure => 'link',
      target => '/var/www/html',
 }
#media.txt file creation
 file { '/opt/data/media.txt':
      ensure => 'present',
      content => '',
 }
}
node 'stapp01.stratos.xfusioncorp.com', 'stapp02.stratos.xfusioncorp.com', 'stapp03.stratos.xfusioncorp.com' {
include symlink
}

Step 2) Validate the syntax 

root@jump_host /etc/puppetlabs/code/environments/production/manifests# puppet parser validate apps.pp

Step 3) Run puppet agent -tv on app server 1 and validate if the symlink and empty file is created. 

[root@stapp01 ~]# puppet agent -tv

Step 3) Run puppet agent -tv on app server 2 and validate if the symlink and empty file is created.
