Puppet Create a FIle

Question: 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 task below:

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

Using /etc/puppetlabs/code/environments/production/manifests/blog.pp create a file media.txt under /opt/sysops directory on App Server 1.

Note: Please perform this task using blog.pp only, do not create any separate inventory file.

Please Note :-  Perform the below commands based on your question  server,  user name & other details might differ . So please read task carefully before executing. All the Best 👍

Solution:

1. Go through the folder mentioned in task and create puppet files 

root@jump_host /# cd /etc/puppetlabs/code/environments/production/manifests/ root@jump_host /etc/puppetlabs/code/environments/production/manifests# ll total 0 root@jump_host /etc/puppetlabs/code/environments/production/manifests# vi blog.pp root@jump_host /etc/puppetlabs/code/environments/production/manifests# cat blog.pp class file_creator {   # Now create media.txt under /opt/sysops   file { '/opt/sysops/media.txt':     ensure => 'present',   } }  node 'stapp01.stratos.xfusioncorp.com' {   include file_creator } root@jump_host /etc/puppetlabs/code/environments/production/manifests#

2. Validate the puppet files by below command.( refer Video below for clarity )

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

3. Login on all  App server  (stapp01, stapp02, stapp03 ) & switch to root  user 

root@jump_host /# ssh tony@stapp01 The authenticity of host 'stapp01 (172.16.238.10)' can't be established. ECDSA key fingerprint is SHA256:w9cDRojDoclOxdu1W23Ns2HPyANPrDzhk9VfqtTDoJQ. ECDSA key fingerprint is MD5:a8:3b:55:35:c2:5c:56:76:c8:d0:78:13:7a:4d:8b:e1. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'stapp01,172.16.238.10' (ECDSA) to the list of known hosts. tony@stapp01's password: [tony@stapp01 ~]$ sudo su - 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. [sudo] password for tony: [root@stapp01 ~]#

 4. Run Puppet agent to pull the configuration from puppet server

[root@stapp01 ~]# puppet agen -tv Info: Using configured environment 'production' Info: Retrieving pluginfacts Info: Retrieving plugin Info: Retrieving locales Info: Caching catalog for stapp01.stratos.xfusioncorp.com Info: Applying configuration version '1625738289' Notice: /Stage[main]/File_creator/File[/opt/sysops/media.txt]/ensure: created Notice: Applied catalog in 0.03 seconds [root@stapp01 ~]#

5. Validate the task by running

[root@stapp01 ~]# ll /opt/sysops/ -rw-r--r-- 1 root root 0 Jul  8 09:58 media.txt [root@stapp01 ~]#

Please Note :- I have showed only for stapp01. 

You have to do this in all app server stapp01,stapp02, stapp03. 

6.  Click on Finish & Confirm to complete the task successful
