Infrastructure-as-Code: Understanding CoreOS Ignition

The previous post introduced the Ignition file that is being used to configure the CoreOS nodes that will eventually be used for running Kubernetes. The Ignition file is a JSON formatted flat-file that needs to include certain information and is particularly sensitive when improperly written. In an effort to help users of Ignition, the CoreOS team have provided a Config […]

Infrastructure-as-Code: Bootstrap CoreOS with Ignition

The first post in the series went over the design goals and the logical diagram of the Kubernetes environment. This post will include the necessary steps to PXEBOOT a CoreOS node, install the VMware Tools included version of CoreOS and perform an initial configuration of the CoreOS node with Ignition. After determining what the Infrastructure-as-Code project would be working to […]

Infrastructure-as-Code: Project Overview

To accomplish this, I am using (and learning) several technologies, including: Container OS (CoreOS) for the Kubernetes nodes. Ignition for configuring CoreOS. Ansible for automation and orchestration. Kubernetes VMware NSX for micro-segmention, load […]

There are lots of exciting things happening in the cloud native space, and CoreOS, with its heavy influence with Kubernetes is at the forefront of much of the innovation. The conference itself was on the smaller side, but the amount of […]

It then became the design I would submit for my VCDX Defense and spend a couple hundred hours pouring over and documenting. Since then it has included helping other […]
