Adventures in architectures
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 […]
Creating an Ubuntu 18.04 LTS cloud image for deployment on VMware 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 […]
I had a question last week from Bozo Popovic during our EMEA field SE training session on vSAN operations relating to SPBM support for service providers that use vCloud Director in their environments. Next up Mr. @mylesagray giving a #vSAN operations overview to our EMEA field at the @vmwarevsan workshop this morning pic.twitter.com/48seQc8i7d — Cormac […]
After deploying a vSAN cluster, the need sometimes arises to make changes to its network configuration, such as migrating the vmkernel network of the cluster to a new subnet. This requirement may appear for example when changing the network in which the vSAN cluster is running, or even, in a more complex scenario such as […]
I was recently rebuilding part of my lab infrastructure, and as part of it, I wanted to migrate my vCD cells from two IPs each to a single IP (as this feature was added in vCD 8.10) for both the web UI and the console proxy. It simplifies provisioning, potential routing problems, and load-balancer configuration […]
I had a power outage recently that took out my entire lab in a very ungraceful manner – everything, well mostly everything, came back up without a hitch – but NSX was acting a bit weird, so I decided to redeploy the NSX Controllers. I removed all 3 controllers and tried redeploying but ended up […]
Over the last 9 months, a lot has happened in my life; I have a nice titanium plate in my shoulder now courtesy of a major car accident. I changed roles at Novosco from Infrastructure Engineer to Cloud Technologist – focusing more on R&D and emerging platforms, and I helped out Frank Denneman and Niels […]
Over the last 6-9 months, I have been reviewing the vast majority of a new book just released to print by Frank Denneman and Niels Hagoort – The vSphere 6.5 Host Resources Deep Dive. This book is, without a doubt, the most in-depth look at host design I have ever read, we are not talking […]
Out of morbid curiosity (and lack of IPv4 public address space available to me), I decided I wanted to enable IPv6 in my lab. However, before taking the plunge there, I would try it out on my residential ADSL line, I use the same brand of firewall there as in my lab so the experience […]
