Install devx

Option 1: Homebrew

brew tap stakpak/stakpak
brew install devx

Option 2: Binary

Init the project

mkdir myapp
cd myapp
devx project init

Update project dependencies

devx project update

Generate example

devx project gen

This will generate a sample DevX stack and builder. You create a stack to define your workload and what it needs to run.

stack.cue
package main

import (
"stakpak.dev/devx/v1"
"stakpak.dev/devx/v1/traits"
)

stack: v1.#Stack & {
components: {
cowsay: {
traits.#Workload
containers: default: {
image: "docker/whalesay"
command: ["cowsay"]
args: ["Hello DevX!"]
}
}
}
}

You create a builder for the dev environment to tell DevX how to generate configurations. This step will usually be performed by platform teams or developers wishing to extend the platform.

builder.cue
package main

import (
"stakpak.dev/devx/v2alpha1"
"stakpak.dev/devx/v2alpha1/environments"
)

builders: v2alpha1.#Environments & {
dev: environments.#Compose
}

Build configurations for the dev environment

devx build dev
