In my previous article, titled,“Puppet: Writing simple manifests” , I wrote about how to write simple manifest to create a user.
In this article, we are going to see more complex way of writing manifests using “modules”.
We will see how can we write a simple module called “motd” and display the banner when we login to any puppet-client.

Please follow below steps in sequence:
- Please change to “/etc/puppetlabs/code/environments/production/modules” in Puppet-Master.
2. Now create below Directories as mentioned below:


3. Now go to “manifests” directory inside “motd” directory and create “init.pp” file such that it has entry as below:

4. Now go to files Directory and create a file named “motd” like below.
You can create “motd” like below using some professional banner generator using below link:

5. Now go to “/etc/puppetlabs/code/environments/production/manifests” directory and modify “site.pp” to look like below:


6. Now run below commands in sequence:
puppet parser validate site.pp
puppet apply — noop site.pp
puppet apply site.pp

7. Now logout / log back in in Puppet-Master server. You will see the banner when you login:

8. Now login to Puppet-client and run below command:
puppet agent -t

9. Now try to log out / log back in to puppet-client , you should get something like below as banner when you login.

That’s It. We are done !!
Point to remember
For our example , same result can be achieved if we write site.pp like below. This will set banner on all the servers:

However for better understanding, we have written “site.pp” like earlier in our example so that we can set banners on selective servers only.
Happy Learning !!

Reading your article helped me a lot and I agree with you. But I still have some doubts, can you clarify for me? I’ll keep an eye out for your answers.
