I am posting this because for some odd reason it seems nearly impossible to find this in any of Vmware’s documentation on ImageBuilder. It mentions you can add online repo’s but never gives a link to their online repo with all the ESXi builds.

I recently ran across some links and blogs that listed that path. So, in order to get the online depot imported use this:

Add-EsxSoftwareDepot https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml

esxcli software vib install -d Update-Depot
