#182: Create Node Resources and Develop Basic Module - Rmhibbert/oe2-group-c GitHub Wiki

Step by step

Creating the module

Description: Navigate to the Puppet modules directory on your management server.

Command: cd /etc/puppetlabs/code/modules

---

Creating Required Directories

Description: Create the necessary directory structure for the sudo module.

Command: mkdir -p sudo/files sudo/templates sudo/manifests

---

Creating the init.pp Manifest File

Description: Every Puppet module requires an init.pp file inside the manifests directory.

Command: cd manifests then sudo touch init.pp

---

Editing init.pp

Description: Open init.pp in a text editor and add the following Puppet class definition.

Command: nano sudo/manifests/init.pp

Content of init.pp

class sudo { package { 'sudo': ensure => present, } file { '/etc/sudoers': owner => 'root', group => 'root', mode => '0440', source => 'puppet:///modules/sudo/etc/sudoers', require => Package['sudo'], } }

---

Add include sudo

Description: Add include sudo into the site.pp file in management server

Command: include sudo

---

Adding the sudoers Configuration File

Description: Copy a verified sudoers file into the module’s files directory.

Command: cp /etc/sudoers /etc/puppetlabs/code/modules/sudo/files/etc/sudoers

---

Change Ownership of the sudoers File

Description: Ensure that the sudoers file is owned by the puppet user and group

Command: sudo chown -R puppet:puppet /etc/puppetlabs/code/modules/sudo/files/

---

Restart the puppetserver

Description: Restart the puppetserver on management server

Command: sudo systemctl restart puppetserver

---

Run the Puppet Agent

Description: Execute the following command on the node to apply the configuration

Command: sudo /opt/puppetlabs/bin/puppet agent --server=mgmt-c --no-daemonize --verbose --onetime

---

Challenges

I was having trouble applying the configuration as it kept giving me errors. Additionally, the command provided for applying the configuration was incorrect—I only needed to use the server name mgmt-c instead of the full mgmt-c.oe2.org.nz.
