Ans: “I automated the configuration and deployment of Linux and Windows machines using Puppet. In addition to shortening the processing time from one week to 10 minutes, I used the roles and profiles paradigm and documented the purpose of each module in README to ensure that others could update the module using Git.

The modules I wrote are still being used, but they’ve been improved by my teammates and members of the community.”

Q12) Tell me about a time when you used collaboration and Puppet to help resolve a conflict within a team?

Ans: The development team wanted root access on test machines managed by Puppet in order to make specific configuration changes. We responded by meeting with them weekly to agree on a process for developers to communicate configuration changes and to empower them to make many of the changes they needed.

Through our joint efforts, we came up with a way for the developers to change specific configuration values themselves via data abstracted through Hiera. In fact, we even taught one of the developers how to write Puppet code in collaboration with us.”

Q13) Which open source or community tools do you use to make Puppet more powerful?

Changes and requests are ticketed through Jira and we manage requests through an internal process. Then, we use Git and Puppet’s Code Manager app to manage Puppet code in accordance with best practices.

Additionally, we run all of our Puppet changes through our continuous integration pipeline in Jenkins using the beaker testing framework.”
