GitOps provides a declarative approach for improving the management of application delivery.

In this 50-minute video, Keyhole Principal Consultant Jaime Niswonger discusses basic GitOps fundamentals and various implementations in a Kubernetes environment. He covers GitOps best practices that unify deployment, management, and monitoring for containerized clusters and applications. Then he introduces ArgoCD and shows its capabilities in an OpenShift/Kubernetes environment. Jaime includes his own experiences and what he has seen working with companies across various industries.

The Keyhole team is excited to share an internal educational video that is now available to the public. In our first-ever video release, we discuss microservices platform orchestration from a broad scope.

Specifically, Principal Consultant Jaime Niswonger takes a technology-agnostic look at the “big ideas” integral to platform orchestration for the enterprise. He introduces three popular orchestration platforms, Kubernetes, OpenShift, and Cloud Foundry, and discusses scaling container deployments in the enterprise. The video is 60 minutes in duration.

OpenShift Quick Start: Build, Deployment and Pipeline

This post is a continuation of our hands-on OpenShift Quick Start blog series.

In the first post we introduced OpenShift & its features. In part two, you worked to get OpenShift running locally & adding a Container with an API service to a Pod. In part three, you worked on scaling pods and managing Cluster with the CLI.

This blog continues that series, introducing the automated Continuous Integration / Continuous Delivery (CICD) features of the OpenShift platform using both the Web Console and the Command Line. A hands-on exercise will then show how a Jenkins build Pipeline can be customized…

OpenShift Quick Start: CLI

This post is a continuation of our hands-on OpenShift Quick Start blog series. In the first post we introduced OpenShift, and in part two, you worked to get OpenShift running locally & adding a Container with an API service to a Pod. Make sure you’ve completed that step prior to starting the continued exercise below!

The previous blogs in this series managed OpenShift using the web admin user interface. However, everything that can be done with the user interface can also be done from using the CLI (Command Line Interface). Arguably, developers prefer to interact with text commands, but that’s a generalization.

In this post, we’ll demonstrate common OpenShift commands can be done in the web admin from the command line.

OpenShift Quick Start

Our previous blog in the series introduced RedHat’s OpenShift solution that provides a way for enterprise teams to implement their own PaaS. Essentially, it sits atop the Docker-based Kubernetes platform to provide a ready-to-use DevOps platform.

This blog introduces two hands-on exercises (taken from our OpenShift Course), that work to walk you through the following tasks:

– Installing OpenShift locally
– Adding a Container with an API service to a Pod

Unfortunately, it will take more than this quick start blog to get OpenShift installed and enabled in an enterprise. That said, developers, system admins, and any party that may be working on or responsible for the platform, will benefit from understanding how to get OpenShift up and running on a local machine as shown in this blog.
