Open Policy Agent, Part I — The Introduction

Recently I was looking for a way to implement access control for microservices. I needed a solution that would allow defining complex authorization rules that could be enforced across many services. After searching the web, I discovered a very promising Open Policy Agent project that seems to be the right tool for the job. In this series of three blog posts, I am going to introduce Open Policy Agent to you and highlight how it can help you.

OpenShift Single Sign On (SSO)

I have been asked, tasked, and dropped in by parachute on an extraordinary number of occasions recently to answer questions about, and implement solution for, Single Sign On (SSO) to OpenShift Container Platform. These conversations can start in multiple ways:

 

  • How do I do SSO to OpenShift?
  • How do I integrate OpenShift with my existing SAML identity provider?
  • How do I log into OpenShift with my PIV and PIN?

 

The goal of all of these questions is typically the same and all have the same answer. Organizations typically have an existing SAML based identity provider they use for single sign on, and in the case of many, especially government, organizations the identity is provided by the user via a PIV and PIN.

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.
