Building the Project

This project uses just as a command runner (similar to make). Follow these steps to build the project from source.

Prerequisites

• Go 1.21 or later
• just 1.36.0 or higher command runner - Install with:

  # On macOS or Linux (recommended for specific version)
  cargo install just --version 1.36.0
  
  # On macOS (using Homebrew - may install a different version)
  brew install just
  
  # Or download from https://github.com/casey/just/releases
  

Build Steps

1. Build all binaries

   Run the main build command:

   just build
   

   This will:

   • Format and vet the Go code
   • Generate Kubernetes CRDs and RBAC manifests
   • Generate API documentation
   • Build all binaries for Linux/amd64:
     • bin/fabric - Main controller
     • bin/agent - Agent binary
     • bin/hhfctl - User-facing CLI tool
     • bin/fabric-boot - Boot service
     • bin/fabric-dhcpd - DHCP daemon

2. View available commands

   See all available build targets:

   just --list
   

Other Useful Commands

• Run tests: just test
• Run linters: just lint
• Build for multiple platforms: just build-multi (builds hhfctl for Linux and macOS, both amd64 and arm64)
• Generate code/manifests: just gen

Building Kubernetes Artifacts

To build Docker images and Helm charts:

just kube-build

Built images:

• 127.0.0.1:30000/githedgehog/fabric/fabric:<version>
• 127.0.0.1:30000/githedgehog/fabric/fabric-dhcpd:<version>
• 127.0.0.1:30000/githedgehog/fabric/fabric-boot:<version>

Where <version> is determined by git describe --tags --always.

Description

// TODO(user): An in-depth paragraph about your project and overview of use

Getting Started

You’ll need a Kubernetes cluster to run against. You can use KIND to get a local cluster for testing, or run against a remote cluster. Note: Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster kubectl cluster-info shows).

Running on the cluster

1. Install Instances of Custom Resources:

kubectl apply -f config/samples/

1. Build and push your image to the location specified by IMG:

make docker-build docker-push IMG=<some-registry>/fabric:tag

1. Deploy the controller to the cluster with the image specified by IMG:

make deploy IMG=<some-registry>/fabric:tag

Uninstall CRDs

To delete the CRDs from the cluster:

make uninstall

Undeploy controller

UnDeploy the controller from the cluster:

make undeploy

Contributing

// TODO(user): Add detailed information on how you would like others to contribute to this project

How it works

This project aims to follow the Kubernetes Operator pattern.

It uses Controllers, which provide a reconcile function responsible for synchronizing resources until the desired state is reached on the cluster.

Test It Out

1. Install the CRDs into the cluster:

make install

1. Run your controller (this will run in the foreground, so switch to a new terminal if you want to leave it running):

make run

NOTE: You can also run this in one step by running: make install run

Modifying the API definitions

If you are editing the API definitions, generate the manifests such as CRs or CRDs using:

make manifests

NOTE: Run make --help for more information on all potential make targets
