Setting up K8s and the vSphere Cloud Provider using kubeadm

28/01/2019 by Myles Gray 1 Comment

This post is part of the Kubernetes on vSphere course.

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 […]

Creating an Ubuntu 18.04 LTS cloud image for cloning on VMware

27/01/2019 by Myles Gray 16 Comments

This post is part of the Kubernetes on vSphere course.

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 […]

Replicating SAN on openSUSE with VAAI

Replaying Linux CLI commands with history

20/06/2015 by Myles Gray Leave a Comment

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!

Utilising Kerberos/AD auth in Ubuntu 14.04 with realmd

How to test if 9000 MTU/Jumbo Frames are working

09/09/2013 by Myles Gray 23 Comments

Fairly straight forward this time, you’ve configured your MTU/jumbo frames to be 9000 on your client and destination devices (say a laptop/desktop/server/san/nas) and on ALL your switching devices in between – you’ve done that right? ;) Why not follow @mylesagray on Twitter for more like this!
