Warning

This gist is still a draft. At the moment it is not functional: see basecamp/kamal#257

Motivation

Kamal was designed with 1 service = 1 droplet/VPS in mind.
But I'm cheap and I want to be able to deploy multiple demo/poc apps apps on my $20/month dedicated server.
What the hell, I'll even host my private container registry on it.

Both methods below are almost equivalent, it just depends on which file you want to edit. I'd recommend .bashrc myself, as it doesn't involve editing a local copy of a system file.

If you experience any problems with this, please comment below so that it can be fixed.

Using ~/.bashrc

1. Edit ~/.bashrc with this command:

gedit ~/.bashrc

ismarsantos

step 1 
sudo nano /etc/hosts

add line
127.0.1.1        lvh.me
