Gluster for OpenShift – Part 1: Container-Ready Storage

OpenShift Container Platform (OCP) offers many different types of persistent storage. Persistent storage ensures that data should be insistent between builds and container migrations. When choosing a persistent storage backend to ensure that the backend supports the scaling, speed, dynamic provisioning, RWX/RWO support and redundancy that the project requires. Container-Ready Storage (CRS), or native Gluster for OCP, is defined by the concept of persistent volumes, which are OCP created objects that allow storage to be defined and then used by pods to allow for data persistence.

How To Setup A Redis Server Cluster on Red Hat

So, you’ve been told you need to build a Redis Server Cluster. First, if you don’t know what Redis is you are probably thinking, “What is this weird named thing and what do I need to do”. This guide will walk you through both in a way that will hopefully be easy to follow and be easy to repeat in the future.

While you can have more than three servers in a Redis cluster for the sake of simplicity, we will cover setting up a three server Redis cluster. In our three servers cluster, we will have two Redis servers with one Redis Sentinel with HAProxy to assist the Sentinel.

Much of this guide will work with a tested code stored in GitLab (https://gitlab.com/Kittell-Projects/RedHat/Redis) to make it easier to build the cluster. While this code is tested, it is suggested to build in a development environment first.

Red Hat Summit 2017 – Planning your Cloud and Containers Labs

This year in Boston, MA you can attend the Red Hat Summit 2017, the event to get your updates on open source technologies and meet with all the experts you follow throughout the year.

It’s taking place from May 2-4 and is full of interesting sessions, keynotes, and labs.

This year I was part of the process of selecting the labs you are going to experience at Red Hat Summit and wanted to share them to help you plan your cloud and containers labs experience. These labs are for you to spend time with the experts who will teach you hands-on and how to get the most out of development with containers and in the Cloud using products like OpenShift Container Platform.

Each lab is a 2-hour session, so planning is essential to getting the most out of your days at Red Hat Summit.

As you might be struggling to find and plan your sessions together with some lab time, here is an overview of the labs, you can find the exact room and times in the session catalog. Each entry includes the lab number, title, abstract, instructors, and is linked to the session catalog entry:
