OK. I found the answer to this on myself. So this is to save anyone else from wasting their time trying to figure this out from the manual.
I logged into my head node via my ssh keys as the root user. Then I executed the following:
cd ~/cm
grep password cm-bright-setup.conf
This value was probably randomly set because I didn't specify --cluster-password
when I created the COD.
Then I logged into Bright View using root
and the username and the password listed in this file. Problem solved.
