The experience of writing a book

I wanted to write about my experience (before I forget about it), and as some colleagues asked about it… here we go… As published in the blog entry RHEL8 Administration book, some colleagues and I wrote a book on RHEL8 administration, which can be bought here. Many years ago I started one about Linux, but every time a new paragraph was added, a lot of new ‘TO-DO’ items were appended as the information growth… and as it was a ‘solo’ project, I had other stuff to work on and was parked. ...

Checking the latest logs or list of issues open and closed on github is probably not an easy task or the best way to get ‘up-to-date’ with changes, so I’ll try to compile a few here.

InfraRed for deploying OpenStack

InfraRed is tool that allows to install/provision OpenStack. You can find the documentation for the project at http://infrared.readthedocs.io. Also, developers and users are online in FreeNode at #infrared channel. Why InfraRed? Deploying OSP with OSP-d (TripleO) requires several setup steps for preparation, deployment, etc. InfraRed simplifies them by automating with ansible most of those steps and configuration. It allows to deploy several OSP versions Allows to ease connection to installed vm roles (Ceph, Computes, Controllers, Undercloud) Allows to define working environments so one InfraRed-running host can be used to manage different environments and much more… Setup of InfraRed-running host Setting InfraRed is quite easy, at the moment the version 2 (branch on github) is working pretty well. ...
