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.

Example of Kamal deployment from Github Actions.

Add your applications .env variables to the Github repo as a repository secret, you can find this under the repo settings => secrets and variables => actions

https://github.com/username/repo_name/settings/secrets/actions

you are going to need an ssh private key that your deployment server is aware of (add public key to servers .ssh/authorized_keys) and add the ssh private key as a repo secret

Choices.js Stimulus wrapper

https://joshuajohnson.co.uk/Choices/

Soon, this will be published as an NPM package, but there's an absence of documentation right now. It supports almost all functions from the original library; soon it will support 100% of them.

This wrapper adds Ajax pre-fetch search. Happens if controller has a data-search-path attribute.

Stimulus controller targets use new v2 syntax. Controller attaches a reference to itself on the element so that you can access the internal state from external scripts.

# Put this function to your .bashrc file.
# Usage: mv oldfilename
# If you call mv without the second parameter it will prompt you to edit the filename on command line.
# Original mv is called when it's called with more than one argument.
# It's useful when you want to change just a few letters in a long name.
