vSphere 7 and Kubernetes
There seems to be a lot of confusion around VMware vSphere 7 and Kubernetes on how you can deploy Kubernetes in a lab versus production.
William Lam covers how you can deploy Kubernetes to lab or evaluation. Here: Kubernetes available for evaluation?
VMware vSphere 7 was released April 20th, 2020, and is approaching its 1st milestone of 6 months since GA. My experience tells me you can count on two things:
1) Update 1 proceeds the GA release of VMware vSphere by about 6 months.
2) Customers tend to wait for Update 1 before they install a new version of vSphere in production.
We are approaching the timeframe where more VMware customers will deploy vSphere 7 and might want to take advantage of using Kubernetes.
Let’s start with vSphere 7 Datasheet for critical information:
A requirement for VMware Cloud Foundation 4.x (VCF 4.x)
This always prompts the question of why do we need VCF 4.x?
K8 deployments require NSX-T VCF 4.x is 1st version of VCF that uses NSX-T in the management and workload domains; by making VCF 4.x a requirement, VMware has validation that a customer has NSX-T deploy in a configuration that will support Kubernetes.
Ok, I have VCF 4.x deployed, I am excited to deploy Kubernetes for my development team, but I have to ask is there anything else we need to do before we start?
Yes, one more thing you need to license your clusters to use Kubernetes Licensing for vSphere with Kubernetes the critical piece of information here is:
Assign a VMware vSphere 7 Enterprise Plus with Add-on for Kubernetes license to all ESXi hosts that you want to use as part of a Supervisor Cluster.
Yes, you need to purchase the add on the license to run Kubernetes in production.
I bought an Add-on license. Can we now deploy Kubernetes?
We should have an Architical session before we deploy where we can make decisions on:
What Workload Domain (WLD) should we use for the supervisor cluster?
We can talk about how vCenter inventory has changed now that you enabled your first WLD.
I will cover these topics during my series of blogs on VCF; stay tuned!
