For your VCF homelab you wan to keep the resources small with a little bit overhead.
In this post I will talk about how i managed to deploy a VCF Workload Domain with a single NSX Manager, instead of the standard three nsx nodes.
Warning: Use this only in a Homelab!
The trick is to SSH into your SDDC Manager using the vcf user, and the password used during bring-up of the management domain.
When logged in, run su and log in as root using the password used during bring-up.
run: vi /etc/vmware/vcf/domainmanager/application-prod.properties
Hit i in your keyboard to go into insert mode. Go to the end of the file, and append the following:
nsxt.manager.formfactor=medium
nsxt.manager.resources.validation.skip=true
nsxt.manager.cluster.size=1
nsxt.manager.wait.minutes=120
This will make it so that any workload domain you deploy has one NSX Manager, and that it uses a smaller size. Once done, hit ESC in your keyboard, then type :wq and hit enter to save the file. (w = write, q = quit).
Then run systemctl restart domainmanager and you are good to go!
This worked in my nested Cloud Foundation deployment in my lab running 5.2.1.0.
You will still have to fill in the information for the extra nodes in the UI.
