Puppet Setup File Permissions

Task:

The Nautilus DevOps team has put data on all app servers in Stratos DC. jump host is configured as Puppet master server, and all app servers are already been configured as Puppet agent nodes. The team needs to update content of some of the exiting files as well as update its permissions, etc. Please find below more details about the task:

Create a Puppet programming file official.pp under /etc/puppetlabs/code/environments/production/manifests directory on master node i.e Jump Server. Using puppet file resource, perform the below mentioned tasks.
File beta.txt already exists under /opt/finance directory on App Server 3.
Add content Welcome to xFusionCorp Industries! in file beta.txt on App Server 3.
Set permissions 0777 for file beta.txt on App Server 3.
Note: Please perform this task using official.pp only, do not create any separate inventory file.

Step 1) Create a puppet class

root@jump_host /# cd /etc/puppetlabs/code/environments/production/manifests

root@jump_host /etc/puppetlabs/code/environments/production/manifests# vi official.pp

class file_permissions {

  # Update beta.txt under /opt/finance

  file { '/opt/finance/beta.txt':

    ensure => 'present',

    content => 'Welcome to xFusionCorp Industries!',

    mode => '0777',

  }

}

node 'stapp03.stratos.xfusioncorp.com' {

  include file_permissions

}

Step 2) Validate puppet class

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

Step 3) Login to stapp03 as a root

root@jump_host /etc/puppetlabs/code/environments/production/manifests# ssh banner@stapp03

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.
