Welcome to the world of DevX, a versatile tool designed to help you build internal developer platforms seamlessly. Whether you want to set internal standards, avoid misconfigurations, or enable infrastructure self-service, DevX is your go-to solution. In this guide, we will walk you through the installation and usage of DevX and offer troubleshooting tips to help you on your journey.

Installation

Getting started with DevX is a breeze. Here’s how you can install it:

Using Homebrew

• Open your terminal and run the following commands:

brew tap stakpak/stakpak
brew install devx

Downloading the Binary

• Visit the Releases page to download the latest binary.

Using Docker

• To run DevX using Docker, execute:

docker run --rm -v $(pwd):app ghcr.io/stakpak/devx:latest -h

Quick Start

To set up and start your first project using DevX, follow these commands:

devx project init
devx project update
devx project gen
devx build

This transforms your stack for the development environment.

Understanding Configuration Language with CUE

DevX uses CUE as its configuration language, making it easier to manage configurations without worrying about typos. Think of CUE like a well-organized library:

• Every book (or configuration) has its specific place (type), ensuring nothing is misplaced.
• If you ever want to change a book’s title or author (transform its format), it’s straightforward.
• CUE lets you validate configurations even before applying them, avoiding those awful surprises when you make a typo.

You can find a detailed primer on CUE here.

Creating Stacks

To develop your application stack, you can define workloads and dependencies easily. Here’s a simple tutorial:

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!"]
                }
            }
        }
    }
}

Think of it this way: creating an internal developer platform with DevX is like preparing a recipe. You gather your ingredients, ensure you have all the right tools, and follow a clear step-by-step process (or code) to whip up a delicious dish!

Validating Configurations

Before deploying, it’s crucial to validate your configurations. Run:

devx project validate

This will confirm that everything looks good before you proceed!

Troubleshooting Tips

If you encounter issues, consider these troubleshooting instructions:

• Verify that you have installed DevX correctly by checking its version with devx --version.
• Ensure you’re in the correct directory when running commands.
• Check for any Docker-related issues if you’re using the Docker image.
• If configurations fail to validate, inspect your CUE syntax closely.
