Flux

A Carvel package for Flux, a continuous deployment solution for Kubernetes powered by the GitOps Toolkit.

🚀  Getting Started

Prerequisites

• Kubernetes 1.29+

• Carvel kctrl CLI.

• Carvel kapp-controller deployed in your Kubernetes cluster. You can install it with Carvel kapp (recommended choice) or kubectl.

  kapp deploy -a kapp-controller -y \
    -f https://github.com/carvel-dev/kapp-controller/releases/latest/download/release.yml

Installation

Add the Kadras package repository to your Kubernetes cluster:

kctrl package repository add -r kadras-packages \
  --url ghcr.io/kadras-io/kadras-packages \
  -n kadras-system --create-namespace

Installation without package repository

The recommended way of installing the Flux package is via the Kadras package repository. If you prefer not using the repository, you can add the package definition directly using kapp or kubectl.

kubectl create namespace kadras-system
kapp deploy -a flux-package -n kadras-system -y \
  -f https://github.com/kadras-io/package-for-flux/releases/latest/download/metadata.yml \
  -f https://github.com/kadras-io/package-for-flux/releases/latest/download/package.yml

Install the Flux package:

kctrl package install -i flux \
  -p flux.packages.kadras.io \
  -v ${VERSION} \
  -n kadras-system

Note You can find the ${VERSION} value by retrieving the list of package versions available in the Kadras package repository installed on your cluster.

kctrl package available list -p flux.packages.kadras.io -n kadras-system

Verify the installed packages and their status:

kctrl package installed list -n kadras-system
