Floating Kwaaaay with Podman and systemd

This post was originally published on the ETI blog here.

Red Hat Quay, (or Kwaaaay as my US colleagues pronounce it), is a Container Registry originally from the guys at CoreOS, who were recently purchased by Red Hat. A container registry plays a pivotal role in a successful container strategy, making it simple for developers and administrators to store, manage, distribute and deploy container images across their container platforms, be that on a laptop, standalone server or a distributed solution like Kubernetes.

Remote Debugging of Java Applications on OpenShift

This post was originally published on Ales Nosek – The Software Practitioner.

In this article I am going to show you how to attach a debugger and a VisualVM profiler to the Java application running on OpenShift. The approach described here doesn’t make use of the Jolokia bridge. Instead, we are going to leverage the port-forwarding feature of OpenShift.

4 ways to jump start an Open Source & Agile Automation Culture

Automation within enterprise IT is not a new topic. Whether it’s automating the creation of a user desktop or a server, the drive has always been to automate as much as possible to achieve faster time to market and efficiency. What has changed, though, is the number of infrastructure elements one can automate within an IT org. I still remember my first job in college 15 years ago where I used a variety of tools to automatically deploy and configure Windows XP simultaneously across 50 desktop machines for a classroom lab environment. Today not only can we automate desktop computer deployments but also servers, applications, and even networking.

Welcome to the AI Thunderdome: Using OpenStack to accelerate AI training with Sahara, Spark, and Swift

Like many others in the technology industry, I share a passion for artificial intelligence (AI). This year at OpenStack Summit in Berlin, I presented a talk around parallel AI training. OpenStack lends itself well to big data problems.

Steps for testing DISA STIG controls against Satellite 6

Security technical implementation guides (STIGs) provide a standardized set of security protocols for practically any system. From networks to servers and computers, STIGs are designed to enhance overall security and reduce vulnerabilities. But what happens when the guidelines vary across an enterprise? How do you apply these to a specific product without breaking it? Challenge accepted.

PAM – Pluggable Authentication Modules for Linux and how to edit the defaults

Originally posted on She ITs and Giggles blog.

Most of us have been using PAM when authenticating without really thinking about it, but for the few of us that have actually tried to make sense of it, PAM is the partner that always says “no”, unless otherwise stated. It’s the bane of any sysadmin’s existence when it comes to making system x secure, and it becomes a major pain point on and off when I forget about the normal rules of engagement.

Hey Tate: Libvirt Virtualization and running ipa-server for DNS to resolve Openshift routes on the network

Hello, my name is Christopher Tate and I want to show you how to set up virtualization and a virtual machine for DNS and Identity Management to open our OpenShift web console and routes to the network.

In my previous videos, I showed you how to install OpenShift with valid SSL certificates.

Hey Tate: Step by step securing OpenShift and routes with SSL certificates for development.

Hey Tate: Step by step securing OpenShift and routes with SSL certificates for development

I created this series of videos to show how to first, purchase a domain name for cheap, to use for valid SSL certificates and URLs for all your applications. I do this for learning and developing applications, not just for deploying to production. Then I show how to generate a free SSL certificate for secure, verified https connections to your sites. Then I show you how to run OpenShift locally, from the ground up, with SSL certificates for the web console, and all routes.
