Developing infrastructure code is challenging: quickly-changing tools, ever-higher quality expectations, and fluid teams.

What would life be like if your team had a containerized infra development environment supporting the development process by standardizing the tooling to build, test, and deploy infra code through the stages of the development lifecycle?

We will demonstrate and explore a simple open source project providing a portable infra development environment using Terraform, kitchen-terraform, and rspec. Patterns will be universal.

This talk will dive deeper into the 'Packaged Environment' pattern described at: https://www.qualimente.com/2017/01/17/simple-ways-to-start-using-docker/#Pattern_Packaged_Environment

Overview

This is a simple demonstration of generating core files for crashing processes that happen to be containerized to a known location on CentOS 7.

Terminal 1 - Configure System and Run Process

Configure Linux kernel with a core pattern that puts files at a well-known location.

The location will be interpreted from the crashing process' perspective of file paths [1]
