Thanks for the instructions. I did something very similar from instructions I found on the internet.
I created the key and registered the key in the appropriate file on the ESXi host and confirmed.
When I try starting the pi-control container this time I get the following generated in the log:
Warning: Permanently added '192.168.0.200' (RSA) to the list of known hosts.
Permission denied (publickey,keyboard-interactive).
If the key I created was properly registered on the ESXi host I should be able to SSH to the ESXi host from the Xpenology DSM teminal without the password but I always get the password prompt.
I found this article which seems to indicate that I might need to make some more changes to the ESXi host
