I’ve decided to write this blog post after noticing how many people were asking me to make gettext optional when building fswatch. At the beginning I actually thought it was optional.

Since the release of the OpenShift Container Platform (OCP) it has been my desire to provide a simple, fully configured and easy to use installation. This installation needs to have the Red Hat Middleware product streams installed (pre-configured container options) and all the extras like source to image and .Net Core containers.

Running a linux distro on android devices is a hot topic these days, and why not? After all, android is already based on linux kernel, but a pretty much locked-down and dumbed-down version of it. The OEM doesn’t give you root and in most cases, not even an open source bootloader or kernel. That way, its good for maybe the ...

Note: This article largely borrows from my previous writeup on installing K8s 1.7 on CentOS. Getting a local K8s cluster up and running is one of the first “baby steps” of toddling into the K8s ecosystem.
