In the last post, we went through creating our home lab Kubernetes cluster and deploying the Kubernetes dashboard. In this post we are going to create a couple more stateless applications. What is BusyBox Several stripped-down Unix tools in a single executable file. Commonly referred to as the “Swiss army knife tool in Linux distributions” I began by just testing this following a walkthrough tutorial but then later realised that this is a great tool for troubleshooting within your Kubernetes pod. You can find out more information here on Docker Hub. kubectl run myshell –rm -it –image busybox – sh Some things you didn’t knowRead More →

In the last post, we walked through the pretty basic way of getting our physical and virtual environment ready for our Kubernetes cluster. This post will cover the Kubernetes cluster setup steps. Kubernetes Cluster At this stage, we just have 3 virtual machines running Ubuntu on a flat layer 2 network. Now things get a little more interesting, in one of the last steps of part 1 we touched on installing kubeadm and this is where I am going to focus my installation and configuration, however, you can use the more challenging approach and build out from scratch. Kubernetes the Hard Way on Bare Metal,Read More →

This series will document my journey in creating a Kubernetes cluster in my home lab using basically the hardware I have available. I do also have some RaspberryPi options but for the purpose of this series, I am going to focus on x86 architecture. The reason for doing this is purely for learning I fully expect the majority of companies to take the easy button and leverage one of the many managed Kubernetes services possibly in the public cloud or from a service provider, the reason for this is because it really does offload the overhead of management and administration off to the service providerRead More →

The next #ignitethetour training I took was with Cecil Philip of Microsoft. Data is of huge interest of me and has been my whole IT career, knowing where that data is stored for production, backup for analytics regardless of it being on premises or in the public cloud or even being hosted by a service provider. I think with the options we have available today to store our personal data and our mission critical enterprise data and everything in between we have so much choice. This session was focused on how the cloud could help when it comes to storing your data in Microsoft Azure.Read More →

Well it is Summer some place, but this learning curve has been going on since the summer in England where I really wanted to take some of the pre events season down time and learn something new, this has spanned a wide range of new and upcoming technologies of which some I have not even written about yet but I have been looking at I promise. A big focus on Containers & Kubernetes Public Cloud Hyperscalers (Microsoft Azure, AWS and Google Cloud Platform) Infrastructure as Code & Automation My aim for the public cloud and in particular Microsoft Azure was to get a better understandingRead More →

Terraform As I said above, I wanted to get into some of the examples of actually some of the tools used to provision your infrastructure using code, terraform use the terms “Execution Plans” to describe the way your code is deployed. Terraform was created by a company called Hashicop they have a number of really good tools in this space. The biggest pull factor for me and why I wanted to kick things off with Terraform is because Terraform is cloud agnostic or pretty much any infrastructure agnostic as you can use Terraform with you on premises vSphere environment as well as AWS, Azure andRead More →

From my first post I wasn’t sure what to expect when diving head first into this newish world of Infrastructure As Code and what it would look like specifically in another world I wasn’t too sure about which is Cloud Computing. I felt that although I believe in the first post, I have grasped the reasons behind and the benefits for Infrastructure As Code I think we need to take a look how things were traditionally managed and still are for the most part in on premises datacentre. But also highlight some of the reasons why things are changing. How was infrastructure traditionally managed TheRead More →

In the last post I said I was going to be kicking off my summer project and this year it was going to be around being more aware of cloud computing, by no means am I going to be knowing everything in the 3 weeks I have set aside but I want to be in a better place than I was at the beginning of summer and understand enough to have a good solid conversation with our customers but also the IT Community. First Steps I also mentioned in the first post about some of the resources I was going to get into but thisRead More →

Every year the summer months in the UK and all over I guess are a good time to start not only reflecting but also thinking about things, last year we worked on some pretty interesting Infrastructure as code as part of a project that saw a lot of good content come out around deploying Veeam components using Terraform and CHEF, this actually made up the majority of our VMworld session and a few other events thereafter. This summer I felt it was now around the right time to use these slowly dwindling 3 weeks of summer before we head to VMworld to really focus inRead More →
