OpenShift – From Design and Deploy to Deliver and Transform: Optimising Distributed Teams with Agile Practices

Previously published on She ITs and Giggles.

Overview

Frequently when I’m on site I am not directly asked but I am expected to provide answers to my customers how to get the best use of a technology. In this post I’m examining a recent scenario around providing structure around deploying OpenShift in order to provide a collaboration environment that would aide the use of this technology. We were also deploying OpenShift but writing about OpenShift deployment is a well covered subject across the board.

Communities of practice: Straight from the open source

Every solution starts with sharing a problem. At Red Hat, when we talk about “open source,” we’re talking about a proven way of collaborating to create technology. The freedom to see the code, to learn from it, to ask questions and offer improvements. This is the open source way. However, bringing together people in your organization to collaborate is often easier said than done.

At Red Hat, we’ve created “Communities of Practice” (CoP) to help our own people collaborate, especially on new and emerging technologies–including automation.

This diagram represents the reference architecture for a full high availability and disaster recovery solution. This solution can be individually tailored to address a single availability solution. For example, if only disaster recovery is needed the configuration supports exclusion of the HA replica.

Dynamic SSL certificates using LetsEncrypt on OpenShift

This post was originally published on the ETI blog here.

Managing SSL certificates in OpenShift can be a bit of a chore, especially when you have more than a few routes to manage. Having an automated mechanism to manage this helps with the operational overhead, and in this example LetsEncrypt is the weapon of choice.

You could quite conveniently use a wild card certificate to cover most of your routes but that doesn’t cover every use case that you might have, especially when you manage multiple domains. Consider also that wildcard certificates are deprecated[1] in favour of tooling that can provide programmatic access to easily create and renew SSL certificates on demand. There are a bunch of advantages (and disadvantages) to this and a tonne of articles out there, already covering the nuts and bolts of that topic, so I’m going to skip over that and instead share my experience deploying and using LetsEncrypt on OpenShift.

LetsEncrypt has been around for a while now and has been adopted into many environments so I thought it is about time that I shared how I have applied Lets Encrypt to solve my problem managing certificates across multiple domains on my OpenShift cluster.

Transforming to a DevOps paradigm with latest Culture and Practices course

Digital transformation as a goal is ubiquitous in 2019, and technology is often the focus, followed by processes. The culture aspect is either overlooked or daunting for teams wanting to change and evolve. Silo based organizations, manual processes, and waterfall practices keep teams in the status quo.
