Before I came to Red Hat, I used to work for a Red Hat partner as a consultant and architect. During that time, I was involved in quite a few situations where I had to help people move from one platform to another, most often from some flavor of Unix to Red Hat Enterprise Linux. As Linux is the de facto standard platform for many development teams, it seemed to make sense to translate some of that experience into a...

While validating OpenShift Container Platform on a VMware platform the usage of Atomic OS was also a requirement. In the initial reference architecture, the decision was made to use Red Hat Enterprise Linux as the platform. This platform was then customized and the same packages as in Atomic were installed via Ansible and Red Hat Network. The github repo with those playbooks is here: https://github.com/openshift/openshift-ansible-contrib/tree/master/reference-architecture/vmware-ansible . These playbooks will guide you from start to finish to deploying OCP on VMware...

I came across Linux in 2005, it was Debian . Then followed a love affair with Ubuntu , for which in March 2009 I purchased a netbook Asus EeePC 1000.

The last few years my EeePC with Ubuntu peacefully rested deep in my cupboard. Then there was a chance to clean off the dust. There was a...

(Probably, a more accurate title would be "The Evolution of a Linux Container Developer") Since .NET now runs on Linux (as well as Windows and macOS), the whole world of Linux containers and microservices has opened up to .NET developers. With a large pool of developers, a long track record of success, and performance numbers that are impressive, .NET offers a great opportunity to expand the world of Linux containers to formerly Windows-centric developers. While it’s tempting to rush in...
