Looking into this a little further, it looks like the Nomad instances aren't federating, I realized this when looking at my Consul UI, it doesn't show any region dropdown, and doesn't seem to be aware it's in a cluster.

Reading through the chapter, I am wondering if the issue is due to the fact that the Azure Consul cluster now has to be made up of 1 node (due to what appears to be changes to Azures pricing and quotas), meaning it isn't really a cluster, so when Federation is attempted it disregards Azure since it's not a cluster, if someone with more experience could comment

So it used to be 3 but there was some change to the Azure free tier which limits the number of instances that can be started at a time, and this was causing some issues. Reduced the number to 1. I understand this makes it not a real cluster anymore, but you can always change the value back. I have not had time to look into this further. If you would like to make a PR, i would be happy to have a fix for this.

For anyone coming across this issue, I followed scotts instructions above and bumped the cluster to 3.

Before, there were no regions showing up in my nomad console,

changed code to adjust cluster size

and afterwards, the regions showed.
