This is a simple POC of authoring a Porter bundle with MoonScript.
The deploys an instance of HackMD (CodiMD) using the Helm mixin, backed by an Azure Database for PostgreSQL created using the Azure mixin.
The file porter.moon in this repo contains the bundle definition:
-- porter.moon 🌜💫
import MyCloudApp from require("lib/mycloudapp")
name = "my-cloud-app"
version = "0.1.3"
description = "takes us up to the cloud, the moon even"
-- General configuration. Modify for your own registry. This pushes the
-- invocation image to Docker Hub account/org based on the USER env var.
-- Note: the "my-cloud-app" repo must first be created via Docker Hub UI.
config = {
meta: {:name, :version, :description}
registry: {
host: "docker.io",
repo: os.getenv("USER").."/"..name
tag: version.."-develop"
}
}
export bundle = MyCloudApp(config).bundleThe MyCloudApp class (defined here) defines the all the different mixins, credentials, and actions for the bundle.
This is the resulting porter.yaml after conversion from MoonScript/Lua:

- name: kubeconfig
