Here’s my first post for a while, and in this post, will talk about my journey with using Configuration Management with the overview of the 2 technologies, that I started working on a couple of years ago. Below are the topics I will cover in the next 4 articles, this being the first
- Technology Overview

Over the past year, I have re-started my hobby of running. It all started when. unfortunately, my mum was diagnosed with Cancer. There’s more about that here.

Over the weekend, was my first race of 2018, where I was in the Cancer Research UK London Winter Run. It was my first race outside of South Yorkshire and on a potential flat PB course. The event is well organised and was in its fourth year as an event. With 20,500 people expected and a sold-out event, the race times were different depending on individuals time targets specified at registration. What this meant was that my allocated time was 10:18, for my estimated time, which was around 1 hour. I entered this race before I ran Percy Pud, so didn’t think I could get below the 1-hour barrier.

As most of you are aware, my mother was diagnosed with stage 2 non-Hodgkins Lymphoma in December 2016, It was a lengthy treatment of Chemotherapy, and I would never wish anything like this for anyone.

It’s been a while since I last posted on my blog (almost 4 years, WOW!!!)
A lot of things have changed at work and personal life, and there’s a lot to talk about. The key things in this post is about catching up where I have been
Hopefully, you’ll see more from me, over the next few weeks and months, especially rounding up the new technology I have been working on, and also something, I have taken up in my personal life too.
For those people following my blogs, you would’ve had an all-in-one install all up and running by now; but now we are going to start afresh. We are going to have a fresh system as explained in my first post, with all the relevant RDO packages installed, and we have all the repositories enabled. Now this installation will be for the foreseeable future, so we won’t need to re-install our OpenStack machine.
This post is going to be quite intensive, such that we are going to try and get to the same stage that we finished in the previous post, but with extra compute nodes in mind.

Welcome to the third part of the series of the blog, today we are going to look at installing and configuring OpenStack networking which will allow us to assign a floating IP to the VM created a in the previous post, and then we should be able to ping and SSH to the instance.
You will need to have your system up to the stage where all the RPMs, repositories, and base config of the system is configured, with one instance up, and available. If in doubt, follow Parts 1 and 2 of the series.

Welcome to the second part of the series of the blog, today we are going to look at installing and configuring OpenStack using packstack, which is provided by the RDO openstack-packstack RPM.
You will need to have your system up to the stage where all the RPMs, repositories, and base config of the system is up to follow this blog. See Part 1 of this topic for more information

Before I start, the contents of all files mentioned in this blog are available at (https://gitlab.arif-ali.co.uk/arif/openstack-lab). Also my assumption is that you would have some knowledge of most of the components in OpenStack. Finally, this will be in a few parts so that there’s not as much to take on
Over the past few months, I have been evaluating OpenStack, and trying a few things in a Proof of Concept(PoC) environment, to see how we can use this in the future. I came through many challenges and hurdles, but finally I got the core components working recently.

There are many times in a datacenter, where we can log into the machines remotely, but we are unable to get external access directly from the machine itself.
I have wanted to use wget to download files, but fortunately, I found a new way to do it
