Puppet Install Multiple Packages

Task Requirements :

There are some packages that need to be installed on the (app server 1) in the datacenter. We want to install these packages using puppet only.

Create a puppet programming file blog.pp under /etc/puppetlabs/code/environments/production/manifests on master node and perform below mentioned tasks using the same.

• Define a class multi_package_node for agent node 1 (App Server 1).

• Install net-tools and unzip packages on the agent node 1.

• Make sure to run puppet agent test to apply/test the changes manually.

• Also, make sure to verify puppet server and puppet agent services are up and running on the respective servers.

SOLUTION :

• Navigate to the Puppet manifests directory.

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

• Create a new Puppet programming file called blog.pp, in the blog.pp file, define the class and specify the packages to be installed.

sudo vi blog.pp

• You can find the sample of the puppet file in this link ---- https://github.com/mightygull/Puppet-Files/blob/main/install_multi_package_node.pp

• Now, you need to assign this class to the agent node (App Server 1). To do that, create a new file called site.pp in the same directory.

sudo vi site.pp

• In the "site.pp" file, assign the multi_package_node class to the agent node (App Server 1) by adding the following code:

node 'agent_node1.example.com' { include multi_package_node }

• Replace 'agent_node1.example.com' with the actual hostname of your agent node (App Server 1).

• Save and exit the file.

• Trigger a Puppet run on the agent node (App Server 1) to apply the configuration changes.

  sudo puppet agent -t
