TASK 100: Puppet Create a FIle

Requirements

The Puppet master and Puppet agent nodes have been set up by the Nautilus DevOps team so they can perform testing. In Stratos DC all app servers have been configured as Puppet agent nodes. Below are details about the testing scenario they want to proceed with.

  • Use Puppet file resource and perform the below given task:

  • Create a Puppet programming file ecommerce.pp under /etc/puppetlabs/code/environments/production/manifests directory on master node i.e Jump Server.

  • Using /etc/puppetlabs/code/environments/production/manifests/ecommerce.pp create a file media.txt under /opt/sysops directory on App Server 2.

Notes: :- Please make sure to run the puppet agent test using sudo on agent nodes, otherwise you can face certificate issues. In that case you will have to clean the certificates first and then you will be able to run the puppet agent test.

:- Before clicking on the Check button please make sure to verify puppet server and puppet agent services are up and running on the respective servers, also please make sure to run puppet agent test to apply/test the changes manually first.

:- Please note that once lab is loaded, the puppet server service should start automatically on puppet master server, however it can take upto 2-3 minutes to start.

Steps

Proeed to the specified directory.

cd /etc/puppetlabs/code/environments/production/manifests/

Create the Puppet programming file ecommerce.pp based on the requirements. You may need to switch to root to create the Puppet file. For the server credentials, check out the Project Nautilus documentation.

class file_creator {
  # Now create media.txt under /opt/sysops
  file { '/opt/sysops/media.txt':
    ensure => 'present',
  }
}
 node 'stapp02.stratos.xfusioncorp.com' {
  include file_creator
}

Validate the Puppet file.

puppet parser validate ecommerce.pp

Log-in to the app server and switch to root. For the server credentials, check out the Project Nautilus documentation.

sshpass -p  '**********' ssh -o StrictHostKeyChecking=no steve@172.16.238.11
sudo su

Run Puppet agent to pull the configuration from puppet server.

$ puppet agent -tv
