I think is also important that you need to have docker on the machine, and start it :)

Sorry, what I mean, when you run kamal setup from terminal(example: mac) you need to have docker up and running on your mac. AFAIK

when I try the kamal setup it was complaining about credentials as I was expect they will load via .env, but failled
after I use kamal secrets print, I realize that I ahve no values, so I had to run export KEY from my terminal as kamal will read from there. 

any better ideas here?

  David Kimura  abs. :) they will not be added.  For me is not clear now where to load my ENV. I could just use rails credentials, but happens with all people like me, that Are using .env?

great video!

would love to see this using a bare bone hetzner machine, or multple servers, line ovh, hetzner, DO just to see how that will look
