Adventures in architectures
Introduction K8s lifecycle is something people are still struggling with, despite amazing tools out there like kubeadm which take care of the K8s setup itself, we are still lacking something fundamental – they day-0 setup. Who/what actually creates the VMs and installs the packages on them so we can get to the stage that we […]
This isn’t necessarily a follow-on from the other three blogs so far in this series, but more of an alternative to parts one and two. Following on from those I felt that the process could be much more automated, and less “ssh into every box and change things manually”. After all, the less changes we […]
Using the VCP As of the last part in the series we have a fully up and running k8s cluster with the vSphere Cloud Provider installed! Let’s make sure it works and is provisioning storage for us by deploying a StorageClass and a test app. Prerequisites Tools I am using macOS, so will be using […]
Intro In the last installment we created an Ubuntu 18.04 LTS image to use to clone VMs from for spinning up our K8s nodes, we then cloned four VMs out, one as the master and three to be used as workers. This time we are going to step through installing all the necessary K8s components […]
Intro I have been experimenting a lot over the past 18 months with containers and in particular, Kubernetes, and one of the core things I always seemed to get hung up on was part-zero – creating the VMs to actually run K8s. I wanted a CLI only way to build a VM template for the […]
This article was written a few years back, but never published – it was some work I was doing in my lab to try and get to grips around the work involved in creating a SAN with synchronous replication built in from scratch. It in no way should be used for production, but rather as […]
I have been testing out Runecast Analyzer in my lab recently – it’s pretty badass, you can set it up to scan your virtual infrastructure at a vCenter level and will scan your vC, VMs and hosts looking for KBs that may apply, security compliance and best practises. As you can see my lab isn’t […]
If you’ve been reading my other posts of late, you will have gathered I’ve been building a new lab. I say “new”, the last one was a single R710 with a ReadyNas Ultra 6 attached. So essentially, this is my first REAL lab. It’s mostly based on Dell hardware; it’s cheap on eBay, I like […]
If you’ve just spun up a new vCenter 6.0 appliance, have joined it to the domain and added a new identity source but have found that your integrated windows auth (the handy checkbox you use for SSO) isn’t working with this error: A General System error occurred: Cannot get user info Then it’s because the […]
Very handy little snippet I discovered today, mostly here for my own reference in future. It’s handy to be able to re-play/re-submit commands that you’ve typed into the CLI before on your Linux box, to do this you can use the history command. Why not follow @mylesagray on Twitter for more like this!
