The way IT operations teams deploy and manage their infrastructure is constantly evolving. The latest developments in containers and container scheduling technologies such as Docker, Kubernetes, and Mesos, especially, have gotten a lot of attention, and more and more people in IT and software development are adopting these solutions — and deploying infrastructure in the cloud — all the time.
Managing this modern infrastructure isn't a trivial task — and that's exactly what Puppet is here for. In this post, I am summarizing for you some of the excellent talks that were given at PuppetConf 2016 on container technologies and how Puppet fits into this new IT ecosystem. These talks — all captured on video — really are a must-watch if you are using these technologies, and even more so if you are thinking about adopting them.
If you want to start this video series from the beginning, take a look at why it's important to care about container management, the challenges with container configuration, running Puppet software in Docker, and Kubernetes for Sysadmins.
Using Puppet With Kubernetes and Openshift
OpenShift brings application awareness to Kubernetes. It provides a layer of abstraction for developers, abstracting infrastructure under the hood and allowing developers to focus on their own workflows.
OpenShift provides, as a built-in service, persistent storage for applications that need to be stateful. It is also platform-agnostic, running on all cloud providers as well as bare metal.
Diane Mueller from Red Hat and Daniel Dreier from Puppet gave a talk titled Using Puppet with Kubernetes and OpenShift. The talk discusses the distractions infrastructure can cause, delves into what Kubernetes and OpenShift do, and includes a demo of how Puppet can be used for building containers and creating and managing Kubernetes resources. The talk also covers the business rationale for using these tools together.
