Okd on A Random Walk Down Tech Street

GCP Quickstart Guide for OpenShift OKD

Wed, 07 Oct 2020 00:00:00 +0000

Introduction

I recently did a blog post series. showing how to get started with OpenShift OKD on Fedora CoreOS for DigitalOcean. For that series I wrote a script to do most of the heavy lifting because DigitalOcean isn’t a native supported platform by the OpenShift installer.

Today I’ll show off how to get started in GCP, which is supported natively by the OpenShift installer. This makes it much easier to get started because most of the heavy lifting (including infrastructure bringup) is done by the installer itself.

OpenShift OKD on Fedora CoreOS on DigitalOcean Part 4: Recorded Demo

NOTE: The fourth post of this series is available here.

This blog post is the fifth in a series that illustrates how to set up an OpenShift OKD cluster on DigitalOcean.

Back on August 17th I highlighted this blog post series with a presentation and demo for the OKD working group’s Demo Marathon.

The video is posted on YouTube and also available below. If you’re interested take some time and watch the whole process work and see a cluster up and running at the end.

OpenShift OKD on Fedora CoreOS on DigitalOcean Part 3: Upgrading

Introduction

NOTE: The third post of this series is available here.

This blog post is the fourth in a series that illustrates how to set up an OpenShift OKD cluster on DigitalOcean. The third post in the series covered further configuration of a cluster once it’s already up and running. At this point you should have a cluster up and running and configured with custom TLS certificates and user login’s outsourced to some other identity management service.

Introduction

NOTE: The second post of this series is available here.

This blog post is the third in a series that illustrates how to set up an OpenShift OKD cluster on DigitalOcean. The second post in the series covered the automated deployment and teardown of a cluster using the digitalocean-okd-install script. At this point you should have a cluster up and running and ready to be further customized.

Set Up Custom TLS Certificates

In the first post in this series we mentioned that you may want to have valid certificates for your cluster. For this example we used certbot to talk with Let's Encrypt to get us some certificates for use with our cluster. Assuming the files are in the letsencrypt/ directory we can add the certificates to our cluster like so:

OpenShift OKD on Fedora CoreOS on DigitalOcean Part 1: Deployment

Introduction

NOTE: The first post of this series is available here.

This blog post is the second in a series that illustrates how to set up an OpenShift OKD cluster on DigitalOcean. The first post in the series covered some background information and pre-requisites needed for deploying a cluster. At this point you should have chosen the domain for your cluster, set up your registrar to point to DigitalOcean nameservers, installed all necessary software (doctl, openshift-install, oc, aws cli, etc..), and configured appropriate credentials in your environment (DIGITALOCEAN_ACCESS_TOKEN, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY).

OpenShift OKD on Fedora CoreOS on DigitalOcean Part 0: Preparation

Tue, 28 Jul 2020 00:00:00 +0000

Introduction

This blog post is the first in a series that will illustrate how to set up an OpenShift OKD cluster on DigitalOcean using the bare metal install documentation (user provisioned infrastructure). OKD has tight integrations with the Operating System and uses Fedora CoreOS as a platform for driving the underlying infrastructure, thus we’ll be deploying on top of Fedora CoreOS images inside of DigitalOcean.

The documentation for OKD is pretty comprehensive, but there is nothing like having a guide to help fill in some of the gaps and show an example of it working with real world values. This series aims to do just that.

The K9s TUI for Kubernetes

Sat, 18 Jul 2020 00:00:00 +0000

If you’ve ever had a chance to “nerd out” with me much I’ve probably told you about at least one TUI that I use to make my daily work life easier. Some of my favorites include htop, tig, tmux (not sure if tmux counts), etc..

Lately I’ve been finding myself using Kubernetes/OpenShift much more and I have often thought to myself I wish a nice TUI existed to get in and navigate resources in a Kubernetes environment. The various web interfaces are nice and comprehensive, and the CLI is awesome too, but each of them are too far on the fringes of what I’ll define as my sweet spot for discoverability vs speed vs power. A well designed TUI sits right in the middle and makes me feel right at home.
