GitHub Learning Lab

This has been cross posted from my own blog vGemba.net. Go check it out.

Introduction

At a VMUG last year during a presentation by Chris Wahl he recommended that all ops people like me learn a Distributed Version Control System such as GitHub. I use GitHub for my blog and storing some files, and still had not really scratched the surface of it.

Last month GitHub released a tool called GitHub Learning Labthat is basically an app that starts a bot that leads you through some training on the use of GitHub.

Lessons

So far there are five lessons available:

  • Introduction to GitHub
  • Communicating using Markdown
  • GitHub Pages
  • Moving your project to GitHub
  • Managing merge conflicts

In the Introduction to GitHub lesson you learn about:

Coommunity Mythbusters

At the recent meeting the Scottish VMUG Leaders introduced everyone to the Coommunity. The leaders encouraged attendees to speak to themselves and other members of the Coommunity (Colin Westwater, Craig Dalrymple and Martin Campbell) about taking part. It was nice to hear that some attendees did take up the challenge and actively seek out the members to talk to.

Here is some info to help bust those myths,  for those looking to contribute.

I need to be a triple VCDX etc to be able to contribute. Continue reading

vSphere 6.5 Update 1 Security Configuration Guide Released

This has been cross posted from my own blog vGemba.net. Go check it out.

Introduction

On the 12th March 2018 VMware released the latest version of the vSphere Security Configuration Guide. This is an indispensable guide for securing your vSphere infrastructure which I highly recommend all VMware admins read.

Purpose

I have been following the guide for a few iterations now. Back in the early versions there were a lot of settings that could mean the over zealous administrator could have gone in and potentially caused problems. For example in the v5.1 version of the guide there were 172 settings listed over multiple sheets. In the latest version there are 68. A couple of reason for this are the mitigation change has been eradicated due to code changes or the guidance is no longer required because the software is secure by default.

Also included are some common sense ‘best practices’. This goal of secure by default can be seen in the graphs in the blog post from VMware. In vSphere 6.5 there were 24 settings available to harden the deployment. In 6.5 Update 1 there are now 10 due to VMware coding the guidelines into the code. So for that 68 Guidelines 10 are Hardening settings with 58 Non-Hardening (Audit only + Site Specific). Great job VMware! Continue reading

VCAP7-CMA Exam Review

Recently I sat the VCAP Design exam for Cloud Management and Automation based on vRA7.2. Previously I had sat the version 6 exam and this was based on the traditional split of visio based canvas scenarios and drag and drop questions.  I learned that this version of exam has significant changes to it, and in fact there are no more canvas style questions. Indeed most questions are multiple choice with some drag and drop. The time allocation was also less than before, now only 130 minutes to answer 60 questions!

Study Mode

Going into study mode I felt confident having used vRA7.3 for some time now, however there are still slight differences between 7.2 and 7.3 that I had to brush up on. Additionally, due to the architecture of the product I work on, we don’t have a need to utilize all of what vRA can offer, so I also required a refresher on things like approval policies and the vRA portal.

So, where to start? I am lucky enough to have a lab in work where we develop, so I could use that for a “play around”. I created a new tenant and simply clicked everywhere and anywhere to get a feel for all vRA7 has to offer. I also completed some Hands on Labs from VMware. They are an excellent resource and cater for all levels. From here you can also click around – no need to follow the guide :).  I did focus, however, on the vRA/NSX integration labs. I much prefer these labs to reading but I also brushed up on the design qualities that are always part of these types of exams. Having sat a few based on the DCV track, I always refer to Paul McSharrys official guide and also the DCD 5.5 Study Pack from Jason Grierson which is an excellent reference. I also should point out that the official exam guide here contains some really important references. Continue reading

vExpert 2018

VMware vExpert 2018

A few weeks later than planned, yesterday was the day many of us were waiting for. vExpert 2018 announcements were due. We had a sneak peak of the application process and it was clear the standards were being rigorously evaluated. Everyone seems in agreement 2018 has been the hardest year yet to make the grade

So after the delay and a frustrating day watching my inbox last night the news I was waiting for finally arrived.

vExpert Announcement

For those that aren’t familiar with the programme;

Program Overview

The VMware vExpert program is VMware’s global evangelism and advocacy program. The program is designed to put VMware’s marketing resources towards your advocacy efforts. Promotion of your articles, exposure at our global events, co-op advertising, traffic analysis, and early access to beta programs and VMware’s roadmap. The awards are for individuals, not companies, and last for one year. Employees of both customers and partners can receive the awards. In the application, we consider various community activities from the previous year as well as the current year’s (only for 2nd half applications) activities in determining who gets awards. We look to see that not only were you active but are still active in the path you chose to apply for. Continue reading

RVTools 3.10 Released

This has been cross posted from my own blog vGemba.net. Go check it out.

Introduction

A utility that I find very useful for checking my vSphere environment is the amazing tool RVTools developed by Rob de Veij. The utility is a comprehensive tool that shows a lot of information from either a vCenter or ESXi host. Some examples of items it can report on are VMs, Partitions, Resource Pools, Licenses, Datastores, Health, etc. Version 3.10 was recently released so in this post I will run through the installation and usage of RVTools.

Installation

The installer is a simple 6.35MB msi file that can be grabbed from the website. You have to submit your details to get access and you will receive emails from Veeam.

The msi is a Next…Next…Next…Finish install:

2018 Personal Objectives (a bit late)

It’s now 6 weeks into the year and i figure it’s finally time to do something that i’ve been meaning to do since late last year… And that’s to to publish my personal objectives for 2018. For me it should be two fold it means they’re publicly out there so i can judge (and be judged) how the year went for me. Secondly i’m sure a lot of my objectives cross over with others in this community so i’m hoping it may spark some conversations and debates as the year goes on.

Certifications:

  • VCAP-DCV – So as posted last year (actually oops, that’s still in draft!) well spoiler alert on the 2nd attempt i got my VCAP-DCD, so it’s high on my list to aim for the 2nd VCAP which would of course unlock VCIX for me. This has to be my #1 goal for the year
  • About a year ago, like so many others i decided to embark on some AWS certs. I started working through the training but then it totally stalled. As i had an expiring exam voucher i forced issue and its scheduled for 3 months time. I need to set aside sufficient time between now and then to give myself any chance. I’m going for AWS Certified Solutions Architect – Associate

New Technologies:

  • Ansible and SaltStack . The scale of things at my new job compared to my old one is staggering. Everything is multiplied by 10x. Therefore it’s going to be essential for me to get much more familiar with configuration management

Using Terraform with vSphere vBrownBag

This has been cross posted from my own blog vGemba.net. Go check it out.

On the 19th December 2017 I presented a session on vBrownbag titled Using Terraform with vSphere. It’s now available on the vBrownBag YouTube channel.

Rebbeca Fitzhugh reached out to me and asked if I would do a session after she read my Terraform Series. Of course I jumped at the chance.

In the session I cover:

  • Terraform Terminology
  • Installation
  • Initialisation
  • Creating a new VM
  • Cloning a VM
  • Variables and the associated files
  • Documentation

It’s pretty much all live demo and I show how easy it is to get started with Terrform to spin up or clone VM’s. I have posted the code I used on my GitHub. This should be the first of a series on Terraform so watch out for more.

I want thank the vBrownBag team for the opportunity to present. I love the content they produce and to be asked to participate was an amazing opportunity.

Scotland VMUG – Glasgow April 26th 2018

Scottish VMUG – Glasgow April 26th 2018

We’re delighted to confirm the date for the next Scotland VMUG and it’ll be in Glasgow on Thursday April 26th.

Iain is always trying to convince me that Glasgow’s miles better, he’s obviously wrong. However on this occasion he has managed to find a fantastic venue for April.  University of Strathclyde Technology and Innovation Centre; a venue that’s valid in both stature and purpose.

The directions i’ve been given are; it’s a 3 minute walk from Queen Street station, assuming that’s based on Iain and James’ little legs so only 90 seconds or so for Sandy and I.
More details on the venue are here; https://www.strath.ac.uk/conferencingandevents/venues/technologyinnovationcentre/

We’re working really hard to finalise speakers and sponsors, needless to say it’s going to be a cracking lineup and we’ll publish all details as soon as we can. As per always we’re looking for anyone community who’d like to participate in someway, please just contact one of the leaders and we can have a conversation about options.

Registration is now open and available here: https://community.vmug.com/events/event-description/?CalendarEventKey=7a1c7931-1d4d-45cb-9580-50a7e7a5fda1&CommunityKey=cae4bc48-6188-4760-8781-3153cddee49e&Home=%2fevents%2fevent-description
