Assignment 2 – Puppet_Module 4_Devops BC = 2330070508

Module 4: Puppet Assignment - 2

Tasks To Be Performed:

1. Add one more slave to the setup
2. Add a condition, if Apache is already installed on the slaves, install NGINX The result should be 3rd slave with NGINX installed.

I spine another EC2 instance 000 follow the same steps previously for agents

Back in the master we sign certificate:

I check agent sudo systemctl status puppet

In master I create a new module to install nginx like i did with apache

update site.pp

root@ip-10-0-1-249:~# cat /etc/puppetlabs/code/environments/production/manifests/site.pp
node default {
  exec { 'nginx_if':
    command => 'apt-get install nginx -y',
    path    => '/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games',
    unless  => '/bin/which apache2',
  }
}
root@ip-10-0-1-249:~#

==maybe change path==

Note

The path attribute in a Puppet exec resource specifies the list of directories that Puppet will use to search for the command being executed. This is analogous to the PATH environment variable in a Unix-like operating system, which the shell uses to locate executables.

In agent3 our latest

sudo /opt/puppetlabs/puppet/bin/puppet agent --test

We try in agent2

sudo /opt/puppetlabs/puppet/bin/puppet agent --test

was nto installed in agent2 cuse it already had apche2 not meeting the conditions
