Puppet Node agent

Step 1: Enable the Puppet Package Repository

Release packages configure your system to download and install appropriate versions of the puppetserverand puppet-agent packages. These packages are grouped into a Puppet Collection repository comprised of compatible versions of Puppet tools.

To enable the repository:

1. Download the “puppetlabs-release” package for your OS version.
   • You can see a full list of these packages on the front page of https://apt.puppetlabs.com/. They are all named puppetlabs-release-<CODE NAME>.deb. (For Ubuntu releases, the code name is the adjective, not the animal.)
   • Architecture is handled automatically; there is only one package per OS version.
2. Install the package by running dpkg -i <PACKAGE NAME>.
3. Run apt-get update to get the new list of available packages.

For example, to enable the repository for Debian Jessie :

wget https://apt.puppetlabs.com/puppetlabs-release-pc1-jessie.deb

dpkg -i puppetlabs-release-jessie.deb

apt-get update

By doing this the sources list have been modified to this :

root@gitlab2-public:~ cat /etc/apt/sources.list.d/puppetlabs.list

# Puppetlabs PC1 jessie Repository

deb http://apt.puppetlabs.com jessie PC1

Step 2: Confirm you can run Puppet executables

The new location for Puppet’s executables is /opt/puppetlabs/bin/, which is not in your PATHenvironment variable by default.

This doesn’t matter for Puppet services — for instance, service puppet start works regardless of the PATH — but if you’re running interactive puppet commands, you must either add their location to your PATH or execute them using their full path.

To quickly add this location to your PATH for your current terminal session, use the command export PATH=/opt/puppetlabs/bin:$PATH. You can also add this location wherever you configure your PATH, such

Step 3: Install the puppet-agent package

For Apt-based systems

On your Puppet agent nodes, run sudo apt-get install puppet-agent.

Do not start the puppet service yet.

Step 4: Start and Configure the puppet service

To start the Puppet service, run sudo /opt/puppetlabs/bin/puppet resource service puppet ensure=running enable=true.

Configure the puppet.conf file with the server information :

root@gitlab2-public:~ vim /etc/puppetlabs/puppet/puppet.conf

# This file can be used to override the default puppet settings.
